When building or renovating a home, many important decisions must be made. While many homeowners may focus on the aesthetics of their siding or windows, your roof can have a surprisingly significant impact on the overall look of a home.

Several factors go into choosing the right roof, from materials and type to color, but one of the most significant choices you will need to make is whether to go with a single or double-pitched roof.

What sets these two options apart, and when is one pitch style superior? Here’s what you need to know about the difference between single-pitched and double-pitched roofs.

What Is a Single-Pitched Roof?

A roof that has just one slope is known as a single-pitched roof. Also sometimes referred to as a mono-pitched roof, the single slope featured on this type of roof is typically set at a low angle. Single-pitched roofs are relatively easy and affordable because they require less labor and fewer materials than their double-pitched counterparts.

The straightforward design of a single-pitched roof also means it is easier to maintain than a double-pitched roof because there are fewer corners and joints where debris and water can collect.

From an aesthetic standpoint, single-pitched roofs look good on homes with minimalist or modern designs. They are also good for structures such as detached garages, sheds, or porches.

What Is a Double-Pitched Roof?

In a double-pitched roof, two slopes meet at a ridge to form a triangle. Also known as a peaked roof or a gable roof, the double-pitched roof is one of America’s most popular roofing styles.

Double-pitched roofs can be more expensive and complicated to build due to the need for more labor and materials. Moreover, because a double-pitched roof has more corners and joints where debris or water can collect, it tends to be more challenging to maintain than the single-pitched varieties.

Nevertheless, double-pitched roofs are the roof of choice for many homeowners because they provide more attic space that can be used to store items or even create additional living space.

They are also highly desired for their aesthetic appeal. A double-pitched roof pairs well with homes featuring a classic or traditional design, such as colonials. It is also a good option for homes in areas prone to severe weather.

Which Type of Roof Is Right for Me?

There are a few factors to consider when determining whether a single-pitched or a double-pitched roof is more suitable for a home.

Which Type of Roof Looks Best For My Home?

A primary consideration is the aesthetics of the two options. Is your vision for a sleek, simple roof, or a more elegant appearance? Consider how either choice will blend with your home’s other features, such as siding and windows.

It may be helpful to take a walk or drive around your neighborhood to compare the different types of roofs on other homes nearby. This may give you a better idea of what you prefer and what will fit in best with the surroundings.

Will My Roof Need More Maintenance?

Maintenance is another important consideration. While all roofs need to be cleaned regularly, it is important to consider that a double-pitched roof will require more significant effort and maintenance and may require more repairs, especially after storms. If you lack the time and resources for roof maintenance, a single-pitched roof may be a better choice.

Will My Roof Need Home Renovations?

You should also take space considerations into account. If you need extra space in your attic, a double-pitched roof may be the better choice. However, if you would instead enjoy more excellent headroom in the rooms of your home, a single-pitched roof could be more suitable.

Does My Roof Fit My Budget?

Your budget will also help guide your decision. If you have a limited budget, you may get a higher-quality roof by opting for a single-pitched roof, requiring less labor and maintenance.

Is My Roof Right For The Weather Conditions of My Area?

A uniquely unavoidable consideration is weather conditions for your region. If your area’s climate is marked by frequent storms, high winds, or heavy snowfall in winter, a double-pitched roof can provide better protection from the elements, while those in milder climates can safely choose a single-pitched roof.

A roof extension is a cost-effective method for extending the length of an existing roof in a renovation to create additional living area or storage space in the home. There are many types of roof extensions, but one of the more popular variations is a gable roof extension.

A gable roof is one of the most popular roofing styles in the country and is marked by two sloping sides that meet at the top to form a triangle known as a gable. Some homes feature more than one gable, and their steep slope helps rain and snow to slide off and avoid causing damage to the home.

Many times, this type of roof is extended by building a flat roof extending from the gable to provide additional living space or create a covered area outside of the home that can be used as a patio or storage area. Another option is extending the existing roof line on the gable end of the home.

For larger extensions, another gable roof section can be added. In some cases, the gable end wall can be extended outward to create a box-like shape with additional room.

What Can a Gable Roof Extension Be Used For?

There are several reasons you might want to add a gable roof extension to your home.

Home Office

Some homeowners use a gable roof extension as a way of creating space for a home office or a study space. Skylights or windows can be added to increase the amount of natural light and air circulation in the space.

Additional Bedroom

A larger gable roof extension can be used to create space for an additional bedroom, whether your family is growing or you want to accommodate guests. Many homeowners who add an extra bedroom with a gable roof extension include a bathroom or a balcony as well.

Storage Area

A gable roof extension can also be used to form a storage area or a hobby room. This area can be built with cabinets and shelves to help keep everything organized.

Playroom

This type of roof extension is also useful in cases where a full room is not needed but the home could benefit from additional space for children to play and store their toys and games.

What Does Getting A Roof Extension Entail?

Before getting a roof extension, you will need to determine your budget and have a rough idea of the design and timeline you would like for the project. You should also find out if you will need to obtain planning permission before the work gets underway.

Next, you will need to enlist the services of a qualified roofing contractor with a proven track record of carrying out jobs safely and efficiently. You will also need an architect to draw the plans for the project.

The precise timeline will depend on the size and scope of the project as well as the materials and contractor availability. When the work is completed, you should ensure that everything has been constructed according to your plans and arrange for any necessary inspections.

Considerations When Getting a Gable Roof Extension

Although a gable roof extension can be an excellent investment for any home, there are some considerations that you need to keep in mind.

Higher Costs Upfront, Lower Costs Overall

The first consideration is cost. Although a gable roof extension is cost-effective, that does not mean it comes with a low price tag. Depending on the design, size and quality of the project you have in mind, a gable roof extension can be rather expensive. You’ll want to obtain quotes from different contractors before you make up your mind and be realistic when planning your budget.

Reduction Of Overall Property Space

It is also important to consider the question of space. Although a gable roof extension will often provide you with additional space within the home or directly outside one of its walls, it is important to keep in mind that it will reduce the space in your yard or your driveway. Work with your roofing contractor to determine how much the roofline will be extended and how it will affect your outdoor space.

Ensure Roof Extension Matches Current Style Of Home

Keep in mind that a gable roof extension may affect the appearance of your home. You’ll want to ensure that the new roof area matches your existing roof and consider how the final design will impact your home’s resale value and curb appeal, particularly if you plan on selling your home in the near future.

Your roof is a crucial component of your home, ensuring that its structure and inhabitants are protected from the elements while maximizing energy efficiency. When your roof is damaged or showing signs of wear or age, a timely replacement can help you protect your investment in your home.

The first question many homeowners have when it is time to replace their roof is how much the project will cost. When you factor in materials and labor, this can be a very expensive undertaking. According to Forbes, a full roof replacement in the U.S. can cost anywhere from $6,700 to $80,000, which is a very broad range. This is because there are so many different variables that influence the cost of a roofing project.

Calculating the cost to replace your roof can be tricky, so here is some advice on how to accurately estimate the cost of a roof replacement.

Estimating Roof Replacement Cost By Size

You can get a rough idea of the cost of your roof replacement by considering its size. As you might expect, replacing a bigger roof is more expensive due to the need for more raw materials and additional labor time. It is not just the overall size of the roof but also the pitch that determines the cost of the project, however.

According to Roofing Calculator, roof replacement costs for a typical 1500-square-foot home with a 5/12 roof pitch and architectural shingles are in the range of $6600 to $9000, while those with a 2000-square-foot-home should expect to pay in the range of $8900 to $12,000. The replacement cost for a 2500-square-foot home’s roof is between $11,100 and $15,000.

Estimating Roof Replacement Cost By Material

The type of roofing that is being replaced is one of the biggest determinants of the cost of the project. Roofing contractors typically supply quotes using the cost per square of materials. One roofing square equals 100 square feet. However, to make this calculation easier for homeowners, we will provide pricing averages for square feet.

Here is a closer look at how much you can expect to pay for different roofing materials; keep in mind that the information provided is only an estimate.

Asphalt Shingles

Asphalt shingles are one of the most popular roofing materials in the country thanks to their durability and affordability. They are currently the most common type of shingles for both residential and commercial buildings throughout the nation, with RoofCalc reporting that around 67% of American residential roofs use asphalt shingles.

Homeowners can expect to spend somewhere in the range of $5800 to $10,000 to replace a full roof using asphalt shingles. However, within the category of asphalt shingles, there are different types that come with different price points. For example, premium architectural shingles can cost between $4.39 and $5.95 per square foot. These are more expensive than other options but are also considered the strongest asphalt shingles, lasting for as long as 50 years.

Architectural asphalt shingles are considered a mid-range option, costing in the range of $4.11 to $5.57 per square foot. They typically come with a 30-year warranty for additional peace of mind. These shingles are more aesthetically pleasing than three-tab shingles.

Three-tab shingles are considered the most basic and affordable type of asphalt shingle, with the national average cost ranging from $3.43 to $4.65 per square foot. In addition to their low price, they are favored by many homeowners because they are quick to install and relatively DIY-friendly.

Roof Size	Three-Tab	Mid-Range	Premium
1,000 Sq. Ft	$3,430 – $4,650	$4,110 – $5,570	$4,390 – $5,950
1,700 Sq. Ft	$5,831 – $7,905	$6,987 – $9,469	$7,463 – $10,115
2,400 Sq. Ft	$8,232 – $11,160	$9,864 – $13,368	$10,536 – $14,280
3,000 Sq. Ft	$10,290 – $13,950	$12,330 – $16,710	$13,170 – $17,850
3,400 Sq. Ft	$11,662 – $15,810	$13,974 – $18,938	$14,926 – $20,230

It is important to note that because asphalt shingles are not able to stand up to severe weather as well as other materials, higher-end asphalt shingles are not a good choice in cases where more durable roofing options are being offered for a similar price. Although asphalt roofs perform well in moderate climates, those with severe temperature fluctuations and strong rains and snow may wish to choose a different material. However, they are considered a good choice for reroofing on a budget before selling a home, particularly a moderately priced one.

Metal Roofing

Metal roofing boasts a long lifespan and plenty of curb appeal, and it is considered a premium roofing material as a result. Homeowners can expect to pay somewhere between $10,000 and $41,000 to replace their existing roof with a metal one.

This is a sizable range because different metals come with different prices, with aluminum roofing generally costing significantly less than copper or steel roofing.

Homeowners who opt for a metal roof can choose from three main varieties that come with different price points. The most affordable is corrugated aluminum roofing, which costs between $6.03 and $8.15 per square foot, according to Roofing Calculator. Metal shingles cost somewhere in the range of $7.69 to $10.41 per square foot, while standing seam metal roofing can cost between $18.11 and $24.50 per square foot for installation. Standing seam metal roofing is aesthetically pleasing and known for being weather tight and extremely durable.

Roof Size	Corrugated Aluminum	Metal Shingles	Standing Seam Metal
1,000 Sq. Ft	$6,030 – $8,150	$7,690 – $10,410	$18,110 – $24,500
1,700 Sq. Ft	$10,251 – $13,855	$13,073 – $17,697	$30,787 – $41,650
2,400 Sq. Ft	$14,472 – $19,560	$18,456 – $24,984	$43,464 – $58,800
3,000 Sq. Ft	$18,090 – $24,450	$23,070 – $31,230	$54,330 – $73,500
3,400 Sq. Ft	$20,502 – $27,710	$26,146 – $35,394	$61,574 – $83,300

The average lifespan of a metal roof is around 50 years, although many metal roofs can last for several decades longer. It stands out as the most affordable premium roofing type and provides durable protection in all climates. As a result, it has seen a significant rise in popularity during the last decade.

It is also suitable for homeowners who are looking to save money on energy costs as well as those who are trying to make their homes greener. Some metal roofs are made using as much as 80% recycled materials. In addition, many metal roofs have received an Energy Star rating as a “cool roof”, allowing homeowners to save on their monthly energy costs.

Another benefit of metal roofs from an environmental standpoint is their suitability for installing solar panels. For homeowners who are building new homes on which they intend to install solar panels, metal is the recommended roofing material.

Wooden Shakes & Shingles

Wooden shakes and shingles have a distinctive appearance and are often chosen for aesthetics alone. While wood shingles are cut smoothly and tend to have a modern style, shakes are made using split wood and have a distinctive textured appearance. Both shingles and shakes may be made of wood such as spruce, pine, cedar, cypress and redwood. While many wood roofs begin with a light color, they often turn silver-gray or dark brown as they age.

Wooden roof replacements generally range from $10,000 to $15,000, according to Roofing Calculator. Wooden shingles cost between $6.02 and $8.14 per square foot, while wooden shakes cost slightly more at $6.47 to $9.12 per square foot.

Roof Size	Wooden Shingles	Wooden Shakes
1,000 Sq. Ft	$6,020 – $8,140	$6,470 – $9,120
1,700 Sq. Ft	$10,234 – $13,838	$10,999 – $15,504
2,400 Sq. Ft	$14,448 – $19,536	$15,528 – $21,888
3,000 Sq. Ft	$18,060 – $24,420	$19,410 – $27,360
3,400 Sq. Ft	$20,468 – $27,676	$21,998 – $31,008

However, it is important to keep in mind that wooden roofs require significantly more maintenance than other materials in order to maintain their appearance and performance. Improperly maintained wooden roofs can experience algae growth or rot and a reduced lifespan. While thicker wood shingles can withstand hail and ice, this material is more prone to catching on fire than other roofing materials when it has not been treated with fire retardants. As a result, it may have an impact on your homeowner’s insurance cost.

Tile Roofing

Tile is one of the more expensive roofing materials available, but many homeowners believe it is worth the investment because of its durability and its pleasing appearance. Clay tiles can last for up to 100 years, although they may become brittle as they approach the end of their lifespan. They cost between $9.09 to $12.29 per square foot.

Concrete tiles are more affordable, costing anywhere from $6.27 to $8.49 per square foot, and they have a similar appearance to clay tiles while coming with the added benefit of being easier to install.

Roof Size	Concrete Tiles	Clay Tiles
1,000 Sq. Ft	$6,270 – $8,490	$9,090 – $12,290
1,700 Sq. Ft	$10,659 – $14,433	$15,453 – $20,893
2,400 Sq. Ft	$15,048 – $20,376	$21,816 – $29,496
3,000 Sq. Ft	$18,810 – $25,470	$27,270 – $36,870
3,400 Sq. Ft	$21,318 – $28,866	$30,906 – $41,786

Slate Roofing

A slate tile roof is widely considered the most expensive roofing option, but its extremely long lifespan – with some slate tile roofs lasting as long as 150 years – and its low-maintenance nature make it a great choice for those who have room in their budget for higher-end materials.

Replacing a slate roof can cost between $40,000 and $54,000, according to Roofing Calculator.

Factors That Increase Your Roofing Cost

Some factors can be difficult to account for when calculating roof replacement cost. Here is a look at some of the most common factors that can cause your price to deviate from the average.

The Cost Of Roofing Materials

The current economic conditions can influence the cost of your roofing materials beyond the variations seen between more affordable materials such as asphalt and higher-end ones like slate. For example, changes in supply and demand, seasonal rate spikes and fluctuations can all play a role.

In addition, natural disasters such as floods and hurricanes can affect the cost of roofing materials by interrupting the supply chain.

Labor Costs

The cost of labor charged by professional roof installers can vary according to local economic conditions. The competition among local roofers, the costs of dumping waste, overheads and profits, and the cost of workers compensation insurance and liability for roofing contractors can all drive up roofing costs.

Labor generally accounts for around 60% of the overall cost of a roof replacement project. This means that on a roof replacement that costs $10,000, around $6000 of it will likely be for labor. According to Roofing Calculator, roofers are generally paid a rate of around $130 per hour, while general roof laborers are paid around $35 per hour.

This is why choosing the right roof replacement contractor is so important. Homeowners should check the roofing company’s reputation, asking friends and relatives for referrals and looking at reviews online to get a better idea of public opinion of the roofers you are considering. You should also check whether the roofing company offers a warranty. Reputable roofing contractors often provide a workmanship and labor warranty that would provide assistance in the event that they make a mistake with their installation.

Although roof replacements are very expensive and homeowners often seek to maximize savings, the cost should not be the sole deciding factor when choosing which contractor to work with. Those that offer unusually low prices may be working with sub-par materials or taking shortcuts with installation that could lead to greater expenses in the long run. Likewise, those that provide quotes on the higher end are not necessarily the best roofers. Obtaining multiple quotes from different roofing companies can help you get a better idea of whether you are paying a reasonable price.

The Complexity Of Installation

The design of the roof, along with its pitch, accessibility, and the number of floors on the home can all play a role in the overall cost of the project. Although it is possible to approximate how much you can expect to spend, most roofers are only willing to provide an accurate estimate after physically inspecting the roof.

Location

The location of the home is another factor that influences the cost of a roof replacement. Homes that are situated in areas that are subject to heavy snowfall on a regular basis may need ice barriers or extra underlayment to protect the home and the roof. For those in warmer climates, certain materials like asphalt may not be good options due to their tendency to crack in high temperatures.

According to RoofCalc, homes situated in the Pacific region can expect to pay around 18% more than the average for the U.S., while those in the West South Central region may find roof replacement costs that are 16% less than the average. However, climate is only one aspect of location that can influence the cost of a roof replacement.

Local and state jurisdictions sometimes have requirements pertaining to materials, methods of installation, or permits that can affect the cost of a roof replacement project.

How Online Roof Replacement Estimate Calculators Work

There are some online roof replacement cost estimators that can give you a very precise idea of how much you might expect to pay in your particular case. For example, RoofCalc.org offers a roofing cost estimator that takes many of the factors involved in a roof replacement into account to give you a tailored range. Their price estimates include installation and materials, but they should be considered a guide only.

The way the calculator works can provide valuable insight into the process of making an accurate estimate, even for those who plan to perform their own calculations.

[caption id="attachment_4816" align="aligncenter" width="500"] RoofCalc Roof Replacement Calculator[/caption]

Total Size Of Roof In Feet

The first metric the calculator asks for is the size of your roof in feet. The ground dimensions are sufficient for most estimates, and there are instructions for accounting for roof overhangs on the site. If your roof has multiple areas, just make sure the overall square footage matches to ensure the calculator considers the right amount of material.

Define Angle/Slope Of Roof

Next, you will need to select the slope, or angle of your roof as this helps provide a more accurate idea of the roof’s area.

Complexity Of Roof Style

The third field prompts users to estimate the complexity of their roof. The pull-down menu provides three options: simple roof, medium difficulty, or a very cut-up roof. They suggest that those who have ranch-style or Cape Cod homes choose simple, while Victorian homes with multiple sections and dormers should select the cut-up option. Those who are unsure can go with medium complexity.

History Of Existing Shingles/Roof

The next box is labeled “tear-off” and is used to indicate whether you will have your previous shingles removed before the new roof is installed. This is highly recommended to extend the lifespan of the roof and give contractors a chance to inspect the underlayment for signs of damage.

Number Of Floors In Home

Next, you will be prompted to select the number of levels in your home from one, two or three. This information helps the calculator determine the ease of accessing the roof, which will influence the labor costs associated with the project.

Desired Roofing Material

The next field is for your desired roofing material, which can have an outsized influence on the overall cost of the roof. Asphalt, metal, natural slate and wood are just a few of the options that are available.

Location Of Home

Finally, you will be asked to note the region of the U.S. in which you reside. A map is provided for those who are unsure. You can also select “national average” to see how the price in your region compares to the country at large.

Final Roof Replacement Estimate

After that, you can click on the “Calculate” button and the system will provide you with cost estimates for your roofing materials and labor, as well as the expenses of tearing off and dumping the old roof and obtaining building permits. You will receive three estimates: low-end, mid-range and high-end. These represent the prices you might be quoted by contractors in your area who cater to homeowners in these price ranges.

Additional Considerations When Calculating Roof Replacement Cost

While many people focus largely on the shingles and labor when determining the cost of their roof replacement, it is important to keep in mind that there may be other considerations to factor in as well.

Decking

The decking is the plywood that is placed over the rafters upon which the roofing material is installed. In cases where a roof has been leaking or is damaged, it may be necessary to replace this decking, which can cost between $2.20 and $3 dollars per square foot.

Keep in mind, however, that contractors may not be able to determine if the decking has been damaged until they have removed the existing roofing material. This means that decking replacement might only be added to the cost of the project after you have been given a quote by the contractor. This should be discussed beforehand to avoid unexpected costs.

Roof Flashing & Pipe Boots

Vulnerable areas of roofs, such as around skylights or at the base of chimneys, often contain roof flashing to make them watertight. This thin plate of galvanized steel can cost between $9 and $11 per foot to replace. Although this may sound like a big expense, flashing is generally limited to the most vulnerable areas of the roof, so it may not add much to the overall price of the project.

Meanwhile, pipe boots are often installed around the base of pipes in the roof to prevent leaks. These cost between $63 and $85 and are generally made of rubber.

Homeowners should keep in mind that both pipe boots and flashing do not have to be changed every time a roof is replaced; those that are in good condition can generally be reused. However, those that are damaged should be replaced or they could cause leaks and other damage that can require more expensive repairs in the future.

Fascia & Soffit

Fascia and soffit materials run along the edge of your roof and are therefore susceptible to rot and water damage. Fascia boards are found along the roof’s lower edge and support gutters and the lower part of the roof, while soffits cover the overhang of rafters or trusses.

These features may need to be replaced as part of a roof replacement, although some homeowners choose to take on this part of the project on their own to save money. Installing new fascia boards typically costs between $4.25 and $8.62 per linear foot, while soffit replacement may cost between $2.80 and $5.28 for each linear foot.

Underlayment

The underlayment of a roof protects the roof’s decking from water damage. This means that if the shingles crack and water makes its way through them, the underlayment will stop it from rotting the overall roofing system.

Underlayment is often required by municipalities for the home to comply with local building code codes. When a roof is replaced, it is often necessary to replace the underlayment as well. This can cost between $1.50 and $2.10 per square foot.

Removing The Existing Roof

Another factor that must be considered when estimating the cost of a roof replacement is the cost of removing the existing roof and disposing of it. This can cost up to $2 per square foot depending on the roof’s characteristics and material.

For example, Roofing Calculator estimates that asphalt shingles cost around $0.50 per square foot to remove, while the cost to remove a square foot of tile roofing approaches $2. Overall, homeowners can expect to pay somewhere between $600 and $3300 to have their existing roof removed and disposed of.

However, some types of roofs do not have to be removed as new shingles may be installed on top of certain types of older shingles. This depends on your local building codes, but many of them will allow two to three layers of shingles to be installed before a full replacement is needed.

Although this may save a significant amount of money at the time of the replacement, it is important to keep in mind that multiple layers will take longer to remove and will drive up the cost of future roof replacements.

Moreover, installing shingles over existing ones means the roofing contractor will not have the opportunity to look at the roof’s decking or underlayment for potential damage. If a problem is not caught during the replacement, another roof replacement may be needed much sooner than anticipated.

Request a Cost Estimate From The Roof Replacement Professionals

Although this information should provide you with a reasonable idea of how much you can expect to spend on a roof replacement, it is not a substitute for the opinion of a professional who has personally inspected your home.

Metal roofs are becoming more popular in both new construction and roof replacements. Could this material be the right choice for your roof? Here is a look at the advantages and drawbacks of metal roofing.

Metal Roofing: The Advantages

Outlined below are some of the reasons metal roofing is such a popular choice among modern homeowners.

Metal Roofs Are Lightweight

One of the biggest advantages of a metal roof is its light weight. In fact, metal roofing is considered one of the lightest of all roofing materials available on the market today. While conventional asphalt shingles can weigh up to 3.5 pounds per square foot and wood shingles and shakes may weigh up to 4.5 pounds per square foot, clay and concrete tile can tip the scales at as much as 10 pounds per square foot. This can place significant stress on the structure of your home. Metal roofing, in contrast, typically weighs between 1 and 3 pounds per square foot depending on the material’s thickness and profile.

The lightweight nature of a metal roof enables homeowners to save on engineering and building the supporting structures. For those who are building new homes or using the roofing for an addition, it is often possible to reduce the number of roof supports needed because the metal is so lightweight.

Metal Roofs Are Fire-Resistant

Most metal roofs have the best fire resistance rating available, Class A, because they are non-combustible. This means that flying embers or sparks will not ignite them. However, it is important to keep in mind that the roof’s general classification also depends on any materials that are beneath its surface that could catch on fire in intense heat. For example, metal roofs that have been applied on top of combustible materials such as wood shingles will have a lower rating as a result.

Metal Roofs Are Long-Lasting

Although not the cheapest material available, a metal roof can last for up to 50 years when installed properly. Metal can stand up to high winds, sheds snow easily, and effectively seals out water while resisting fire, insects and mildew.

Other roofing materials do not fare as well. For example, a flat roof of tar and gravel or fiber cement shingles lasts around 25 years, while modified bitumen roofing and asphalt shingles have a roughly 20-year lifespan. Wood shingles and shakes last for up to 30 years.

Keep in mind, however, that the workmanship, climate conditions and damage caused by severe weather can impact a roof’s lifespan regardless of the material.

They Can Stand Up to Hurricanes and Tornadoes

Metal roofs are ideal for those living in areas that are prone to hurricanes and tornadoes because they can stand up to the high winds and other conditions seen in such storms. In fact, many metal roofing systems can handle winds exceeding 140 miles per hour, like those seen in an F2 tornado. When attached with clips or screws, wind should not be able to get underneath metal roof panels.

Metal Roofing: The Drawbacks

Here are some of the downsides of metal roofing to keep in mind.

Metal Roofing May Be Noisier Than Other Materials

Although metal roofing is not as noisy as most people imagine, it will be noisier than thicker materials like tile or slate during a heavy rainstorm or hail. However, their noise levels are about equivalent to other thin materials, such as wood or asphalt shingles. Those who are concerned about noise can ensure that they use quality materials with structural barriers that can reduce the drumming effect caused by rain or hail. Sound-reducing insulation can also help keep this effect to a minimum.

Metal Roofing Is More Expensive Than Other Materials

One of the biggest drawbacks of a metal roof is its high initial cost. Although it does cost more than asphalt shingles, its price is comparable to other premium materials, such as concrete tile. It is significantly cheaper than synthetic or natural slate and clay tile. However, its long-term durability and reduced need for seasonal maintenance means that those who live in their home for an extended period can enjoy a reasonable return on their investment with a metal roof.

Metal Roofs are Prone to Denting

Metal roofs are robust and designed to stand up to typical weather conditions. However, in areas that experience large-sized hail on a regular basis, some denting may occur, particularly if the roof is composed of a soft metal such as aluminum or copper. Those living in areas where this is a concern can avoid this problem by choosing metal roofing shingles, shakes or metal roofs that have patterned structures to provide additional rigidity. In addition, choosing higher-gauge steel can increase a metal roof’s durability.

One of the most important measurements when it comes to roofing is the pitch. Not only does the pitch play a vital role in the roof’s efficiency and ability to perform tasks such as draining water from the roof, but it also has a significant impact on the home’s overall appearance.

Here is a look at how this important measurement is calculated and how it affects the home.

Roof Pitch Basics

The pitch of a roof is a measurement used to describe how steep it is. It is a very simple calculation to perform; just determine the number of inches that it rises vertically for every foot that it extends horizontally. For example, a roof rising 8 inches for every 12 inches it extends horizontally is said to have an 8/12 pitch.

A high-pitched roof is one that is above a 6/12 pitch. A high-pitched roof has a very steep slope that can move water off of the roof rapidly to prevent leaking and pooling. This also means that it is more difficult for snow to accumulate on the roof and weigh it down, potentially leading to leaks and structural damage. In addition, a steeper roof creates more attic space that the home’s inhabitants can use for storage or living space.

Roofs with a pitch of less than 3/12 are categorized as low pitch. Low-pitched roofs may not move water as quickly off of them as their higher-pitched counterparts, but they are considered easier and safer to walk across. Flatter roofs are associated with lower installation costs because they require smaller rafters or trusses than a high-pitched roof.

Measuring the Pitch of a Roof

The pitch of a roof on an existing home can be measured from inside the attic. Gather an 18-inch or 24-inch level, a pencil and a tape measure and head to the attic. Measure 12 inches from one end of your level and mark it. Then, place the end of the level along the bottom of one of the rafters in the roof and hold it level. Next, find the 12 inch mark that you made previously on the level and measure vertically directly upward to the underside of the rafter; This indicates the number of inches that your roof rises for 12 inches of horizontal extension.

It is also possible to calculate the pitch of a roof on an existing home from on top of the roof itself, although it is essential to carry this out using full protection equipment and a safety ladder. Therefore, this is a job that is best left to experienced roofing contractors who know how to determine when a roof is safe to walk on and who have the appropriate safety equipment.

For new construction, the pitch can be calculated before the roof is even built. First, you must determine how tall the home stands. Then, take the height of all the floors and add them together, then subtract this figure from the home’s total height to obtain the attic height. The attic’s height represents the estimated rise.

Next, you must determine the span of the house using the distance of the width between the home’s exterior walls. Divide this figure in half to obtain the rafter run. Finally, divide the rise by the run to determine the pitch of the roof.

Understanding Types of Roofs

Here is a look at some of the most popular types of roofs and their general pitch patterns.

• • Gable roofs: This is the most common style of roof, with two sloping sides meeting at a top ridge. The end walls have triangular extensions known as gables at the top. This type of roof is the most straightforward when it comes to calculating pitch.
  • Flat roofs: A roof that has a pitch of zero is considered a flat roof. However, it is important to keep in mind that many roofs that look like they are flat do have a subtle slope to facilitate water drainage. Like gable roofs, determining the pitch of a flat roof is very simple.
  • Mansard roofs: A mansard roof is a four-sided roof that has two slopes per side; the bottom slope is steeper than the top slope.
  • Gambrel roofs: A gambrel roof is similar to a gable roof but has more of a barn shape. These roofs feature two sides, and each side contains a shallower slope sitting above a steeper slope.

Flat roofs are an attractive feature of many homes in Alexandria, Virginia. They are affordable and easy to install, and they can provide homeowners with additional space that can be used as a rooftop patio or garden. However, their lack of a slope makes them more vulnerable to the elements.

How To Care For Flat Roofs In Alexandria, VA

This guide to flat roof repair and maintenance can help Alexandria homeowners ensure their roof remains functional for as long as possible.

Conduct Regular Inspections

Flat roofs in Alexandria, VA must be inspected regularly given their susceptibility to leaks and other issues. Fortunately, these roofs are easier than other types of roofs to inspect safely. Homeowners should look for signs of cracking, damage, blockages or aging in the material of their roof.

Pay particular attention to the seams in the roofing system, looking for signs of separating or lifting. Bear in mind that even a small crack could cause a sizable leak, so be sure to repair any cracks right away.

Pay Attention To Roof Blistering

Another problem to look for is blisters, which can occur when air becomes trapped beneath the membrane. These blisters need to be gently popped to allow the air to escape and then patched using roofing cement. For Alexandria homeowners with spray polyurethane foam roofs, areas of discoloration can be a sign that the material is deteriorating. These spots can be addressed by cutting them out and filling the gap with caulk.

Homeowners should also check the flashing that is protecting the protrusions in their roofs, such as roof vents and plumbing stacks, to identify potential leaks. Any gaps or cracks that are identified should be repaired with roofing caulk to prevent water from seeping in through them.

It is equally important to check for leaks from inside the home. For example, damp, brown spots on a ceiling can indicate seepage and should be fixed right away.

In some cases, a personal check may be enough. However, homeowners who suspect something may be wrong with their roof should seek the services of a professional roofing contractor who can identify problems that may not be obvious so they can be corrected before they get worse.

Keep Your Drains Clear

A flat roof is not usually truly flat. Instead, most flat roofs slope to one side very slightly to facilitate drainage. Nevertheless, puddles often form following heavy rain, and this can lead to leaks when the water is left standing for a long time.

Drain openings are typically found in the barrier on the side of the roof that slopes downward. Homeowners should check this area at least once a month to ensure that these drain openings are not blocked by leaves or other types of debris. This check may need to be performed more often in the fall months when leaves are more likely to become airborne in Alexandria.

The drain openings can easily be cleared by pulling the material out of them and discarding it. A flat roof should also be swept twice a month, with homeowners placing all the sweepings in a bucket and throwing them away afterward. As part of this maintenance routine, a garden hose can be used to clear the downspouts to prevent buildup and blockages as dirt and silt may occasionally clog them.

Trim Nearby Trees

Although the weather in Alexandria is generally moderate, occasional storms can wreak havoc on area homes. For homeowners who have trees hanging near or over their roof, trimming them regularly can prevent problems when bad weather strikes. In addition, branches that grow long enough to hit the roof can scrape it and cause damage.

Clear Snow On Roofs

After a bout of heavy snow, check the rooftop for accumulation. This must be cleared out following every snowstorm. Otherwise, the snow melt could turn into ice and create cracks in the roofing.

Ensure Timely Roofing Repairs

In some cases, homeowners can repair simple leaks or cracks by using a patch of their roofing material. For example, an EPDM roof can be easily repaired using adhesives or heat guns in many cases. Materials like PVC and TPO, however, generally need professional repairs.

Bear in mind that water can seep beneath the membrane of the roof across a large distance before making its way through a seam. This can make it difficult to find the exact source of a leak. A contractor can help homeowners find the precise spot of a leak and address it properly to keep water out and avoid further damage.

Some problems may require a flat roof replacement. These include persistent water pooling; multiple instances of damage to the flashing, seams or membrane; impact damage due to falling trees; or multiple leaks.
