Fireproof Your Roof! How to Choose the Right Fire- ...

Can You Really Have a Fireproof Roof?

The roof over your head serves many important functions. It&#;s your home or business structure&#;s first line of defense against sun, wind, precipitation, and other natural threats. Your roof also plays a significant role in maintaining the integrity of your building&#;s infrastructure as a whole. And as an added bonus, an aesthetically-pleasing roof serves to offer a nice boost to the value of your curb appeal.

But is there really such a thing as a fireproof roof? Unfortunately not. Even roofing materials that aren&#;t easily flammable can still melt or warp in the face of a raging fire&#;s extreme heat.

Fireproof vs. Fire-Resistant

While a roof that&#;s completely fireproof may not be a realistic possibility, it is possible to have a roof that&#;s reliably fire-resistant. There are several types of fire-resistant roofing materials available which can provide greater fire protection for your home, your property, and your most precious asset &#; the people that your roof covers! Now that we&#;ve established there&#;s really no such thing as a fireproof roof, let&#;s uncover more about what makes for a truly fire-resistant roof.

Roof Fire Rating Standards and Basics

When we speak about roof fire-resistance, what we mean is how effective a roofing material is in terms of fire prevention from the outside of the roof structure. Interior fire hazards are another matter altogether, and potentially-combustible materials inside your building are evaluated by a different set of standards. Here&#;s a look at how roof fire ratings work:

1. Class A Roofing

Class A roofs are the most effective against severe fire exposure. They last the longest before igniting, and are really the preferred choice for any home. Some Class A-rated standalone coverings include metal, clay tiles, slate, asphalt glass fiber composition shingles, and concrete tiles.

2. Class B Roofing

Class B roofs are known to be effective in the face of moderate fire exposure. To be rated Class B, the exterior roofing must last at least one hour before igniting. Two common examples of roofing materials which fall under the Class B rating are pressure-treated shakes and shingles.

3. Class C Roofing

Class C roofing is only rated for light fire protection. Roofing with a Class C rating is only required to last 20 minutes before igniting. Class C materials are not recommended for any application where fire-resistance is a potential concern. Some common Class C roofing materials include untreated wood shakes, shingles, plywood, and particleboard.

4. Unrated Roofing

If the roofing material in question is unrated, this means it&#;s not even fire-resistant enough to qualify for a Class C rating. Any unrated roofing material should simply be avoided; it&#;s simply not worth the risk! In fact, most local building codes won&#;t allow for any type of unrated roofing material.

A Survey of Some Good, Fire-Resistant Roofing Materials

Thankfully, there are plenty of roof sheathing materials that are known to provide Class A fire protection. Here are just a few of the options available to you:

&#; Slate

Slate is a stone material which combines beauty, durability, and natural fire resistance. Slate is also very slow to weather or break down, and can make for an incredibly long-lasting roof. There are a few drawbacks to slate, though. It&#;s incredibly heavy, it&#;s expensive, and it also requires some specialized knowledge and equipment for effective installation.

&#; Clay Tile

Clay tiles are also produced with natural, non-combustible materials, and clay isn&#;t as heavy as slate. Rounded clay tiles are popular for Spanish-style architecture, as well as for other buildings which carry a Southwestern or mission theme. In order to maintain Class A fire protection however, it&#;s very important that clay tile be installed correctly. Any gaps that remain between the tile and the underlayment can allow fire embers to penetrate.

&#; Concrete Tile

Concrete is another great material to consider if you like the look of tile. Concrete tiles are reliably weather-resistant, they&#;re non-combustible, and they&#;re often more cost-effective to use as compared with other tile materials. In addition, concrete tiles come in a wide range of colors, finishes, and shapes. With concrete, you have more options for customization than you do with slate or clay.

&#; Asphalt Shingles

Surprised to see asphalt shingles on the list? While it&#;s true that asphalt is itself a petroleum-based product, that doesn&#;t mean that shingles can&#;t be fire-resistant. Fiberglass-backed asphalt shingles actually provide some good fire protection, especially when combined with fire-resistant underlayment. And of course, many people like the fact that asphalt shingles are some of the least expensive roofing materials available today. A key drawback to shingles is that they require more upkeep, and a shingle roof will have to be replaced long before any sort of tile roof you might choose.

Two More Fire-Resistant Materials That Are Even Better

While there are many good things that can be said about tile and shingles, there are two more available roofing materials that offer even more benefits. Both of these materials provide Class A fire protection, and they also offer great style, great durability, and little need for ongoing maintenance:

1. Metal Roofing

When you get right down to it, there&#;s really a lot to like about metal roofing. Not only will metal not burn, but metal roofing is also lightweight, doesn&#;t corrode, and needs very little maintenance. There&#;s lots more to like, too. Metal roofs have a long lifespan, are very effective at shedding rain and snow, help to dissipate lightning strikes, and can be certified to withstand hurricane-force winds. In addition, metal can be used on roofs of practically any pitch, from very steep to very low slope.

2. Synthetic Roofing

Sturdy synthetics or composition shingles and tiles can be made to mimic the look of wood, asphalt, or natural tile, and they boast some highly reflective properties which can help to reduce your home&#;s cooling costs. For example, DaVinci Cool Roof tiles have earned the ENERGY STAR designation. They&#;re very long-lasting too; in fact, they come with a 50-year warranty. Oh, and one more thing &#; they&#;re also a Class A-rated material for fire protection!

As wildfires become increasingly common, fire-resistant roofing and siding have evolved from luxury to necessity for many homeowners. These materials improve your home&#;s ability to withstand high temperatures and help slow the spread of flames. In this comprehensive guide, we&#;ll explorethe  top fire-resistant options for both roofing and siding to help you choose the best materials for your home.

Fiberglass-Based Fire Resistant Asphalt Shingles

Fiberglass-based asphalt shingles are the most popular roofing material in the United States, accounting for 80% of the residential roofing market. It isn&#;t hard to see why. Fiberglass shingles are both affordable and durable. As long as they are installed with a code-compliant underlayment, fiberglass shingles provide excellent fire resistance. They can be installed in various weather conditions, and they come in a wide range of colors and styles. 

CertainTeed&#;s Highland Slate shingles offer the best of both worlds: the cost-effectiveness of asphalt and the luxurious appearance of natural slate. They also have a Class A fire rating and can withstand winds up to 110 mph. 

Fire Resistant Recycled-Rubber Tiles

Recycled-rubber tiles like EcoStar&#;s Majestic Slate tiles are an excellent choice for environmentally conscious homeowners. Made with a highly effective fire retardant and installed over a fire-resistant barrier, these tiles have earned a Class C fire rating and Class 4 impact rating from UL.

Superior fire resistance isn&#;t the only benefit of this material. Like CertainTeed&#;s Highland Slate shingles, these particular tiles are designed to mimic the look of slate. They are made from 80% recycled rubber and plastic&#;which means they are exceptionally durable, low maintenance, and eco-friendly. They are much lighter than slate, easier to install, and available in 11 different colors.

Fire Resistant Metal Tiles

Metal tiles are lightweight and low-maintenance, but most impressively, they&#;re noncombustible. When combined with a fire-resistant underlayment, many metal roofing systems can achieve a Class A fire rating. High-quality metal tiles are often coated with UV-resistant materials that reflect heat and resist abrasion.  Many manufacturers also offer long-term warranties that range from 30 to 50 years.

With minimal upkeep, homeowners can enjoy safety, beauty, and cost-savings over the lifespan of the metal tiles. Metal tiles are highly effective at reflecting sunlight, which can help in reducing energy costs. Their sleek and modern appearance can enhance the aesthetic value of a home, making them an excellent choice for contemporary designs.

Fire Resistant Clay Tiles

Traditional clay tiles are both durable and noncombustible, making them an excellent choice for fire-prone areas. There&#;s only one small caveat: If you choose a barrel-shaped variety, you must seal any openings, especially over the eaves. Otherwise, flying embers could penetrate the roof.

Clay tiles provide superior insulation, which can help in maintaining indoor temperature. Their ability to withstand various weather conditions while maintaining structural integrity adds to their appeal. Plus, the natural look of clay tiles can complement a wide range of architectural styles.

Fire Resistant Slate

Slate is often considered the pinnacle of roofing materials thanks to its unique combination of elegance, longevity, and excellent fire resistance. As a noncombustible material, it naturally receives a Class A fire rating. High-quality slate, such as the S1 grade offered by Evergreen Slate Company, is rated to last 75 years or more. It requires minimal maintenance and can withstand extreme weather conditions without cracking or fading.

Slate roofs do come with two major drawbacks: their cost and their weight. Slate is one of the heaviest roofing materials, weighing between 700 to 3,000 pounds per square, and not every roof can support the extra weight. It&#;s also one of the most expensive materials&#;though the extended lifespan and durability of slate roofing justify the expense for many homeowners.

Fire Resistant Stone Veneer

The fire resistance of Natural Stone Veneer International&#;s fieldstone veneer is amplified when applied over masonry-block or ICF framing instead of untreated wood. To maximize the stone&#;s fire-resistant properties, use a fire-rated mortar and perform regular maintenance to prevent cracks.

The natural appearance of stone veneer can significantly boost a home&#;s curb appeal. Homeowners also appreciate its durability and resistance to pests. Regular maintenance helps the veneer remain intact and effectively fire-resistant throughout its lifespan.

Fire Resistant Fiber Cement

Made from a mixture of Portland cement, sand, and wood fibers, fiber cement products usually carry a Class A fire rating. This means they can withstand high heat for 2 to 4 hours before your home&#;s structure starts to fail. Fiber cement siding also offers significant durability against weather and insects, and it&#;s available in various styles and colors for easy customization. Some fiber cement products are even designed to mimic the appearance of real wood.

To maximize their effectiveness, fiber cement products often require a gypsum-board underlayment. It&#;s also important to enclose eaves, soffits, and fascias with the complementary fire-retardant trim to prevent embers from entering through cracks or other flammable surfaces.

Exterior Insulation Finish Systems

Exterior Insulation Finish Systems (EIFS) provide a stucco-like appearance with added insulation benefits. These systems consist of an acrylic-impregnated cement finish applied over fiberglass lath, with a foam insulation layer on the back to prevent cracking. While EIFS products like Dryvit don&#;t have a specific fire rating due to their tendency to fall off when exposed to high heat, they won&#;t compromise the fire resistance of the underlying wall system. 

The insulation properties of EIFS also contribute to energy efficiency by reducing heat loss or gain, which can lead to lower utility bills. This combination of fire resistance and energy efficiency makes EIFS a practical choice for homeowners who want to save money and protect their homes. 

Fire Resistant Treated Wood

For homeowners who prefer the look of natural wood, some companies offer clapboards and shingles treated with UL-approved fire-retardant chemicals. Treated wood siding from companies like Watkin Sawmills combines the traditional look and charm of natural wood with an added layer of fire protection.

It&#;s important to note that the fire-retardent chemicals used in these products will leach out over time. As a result, the wood must be retreated regularly to retain its fire-resistant properties.

Fire Resistant Masonry

The classic appearance of brick and stucco can enhance a home&#;s aesthetic appeal while providing robust fire resistance. Though these materials tend to be more expensive, they are also naturally fire-resistant and offer decades of protection when properly installed and maintained. Masonry materials are also durable and relatively low maintenance.

Depending on the thickness, masonry siding can meet or exceed one-hour fire ratings. To slow heat transfer from the siding to the framing even more, add a layer of gypsum underneath&#;which contains 22% chemically combined water.

Our Conclusion

Consider your budget, local climate, and architectural style when selecting the best fire-resistant materials for your home. While options like fiberglass-based asphalt shingles and fiber cement offer affordable fire protection, premium materials such as slate and clay tiles provide superior durability and aesthetics. Understanding each material&#;s unique characteristics and benefits can help you make an informed decision.
