In this article from Watkins Construction & Roofing, we will be discussing what roofing materials are fire resistant. Among its many important functions, the roof of your home or business serves as the first line of defense against harsh elements.
It protects your home or business from heat, wind, and precipitation, as well as other natural threats. In addition, a beautiful roof serves to enhance the curb appeal of your building and contributes to maintaining the integrity of the building.
Is a fireproof roof possible? Unfortunately, not. Despite their non-flammability, roofing materials can still melt or warp in extreme heat from a raging fire.
Fireproof vs. Fire-Resistant
While a completely fireproof roof may not be realistic, it is possible to have a reliably fire-resistant roof. Your home, property, and most precious asset – the people covered by your roof – are all better protected from fire with the use of fire-resistant roofing materials. After establishing that a fireproof roof does not exist, let’s explore what makes a truly fire-resistant roof.
Roof Fire Rating Standards and Basics
The term roof fire-resistance refers to the effectiveness of roofing material in preventing fires from outside the roof structure. It is another matter entirely when it comes to interior fire hazards and the assessment of materials that are potentially combustible inside a building. An overview of roof fire ratings is provided below:
-
Class A Roofing
There are a few types of roofs available that can survive severe fire exposure, but class A roofs are the best choice because they last the longest before igniting, making them a great choice for any home. Metal, clay tiles, slate, asphalt glass fiber composition shingles, and concrete tiles are examples of Class A-rated standalone coverings.
-
Class B Roofing
Roofs classified as Class B are known to perform well when exposed to moderate fire conditions. To qualify as a Class B roof, its exterior surface must last for at least an hour before igniting. Shakes and shingles that have been pressure-treated are two examples of roofing materials that fall into the Class B category.
-
Class C Roofing
Roofing with a Class C rating is only rated for light fire resistance, it only needs to stay lit for 20 minutes before igniting. Materials classified as Class C should not be used for applications where fire resistance is an issue. Particleboard, plywood, and untreated wood shakes are some materials commonly used in Class C roofing.
-
Unrated Roofing
Roofing materials that are unrated aren’t even fire-resistant enough to qualify for a Class C rating. Roofing materials that are not rated should simply be avoided at all costs – the risk is simply too great! Local building codes don’t allow unrated roofing materials in most places.
A Survey of Some Good, Fire-Resistant Roofing Materials
You have a variety of roof sheathing options available, all of which provide Class A fire protection. Here are a few examples:
Slate
Natural fire resistance, beauty, and durability are all characteristics of slate stone. Furthermore, slate is very resistant to weathering and can last for a very long time. Slate has some drawbacks. To install it effectively, you’ll need specific knowledge and equipment. The material is incredibly heavy, it’s expensive, and it’s also expensive.
Clay Tile
In addition to using non-combustible, natural materials, clay tiles are also lighter than slate tiles. The use of rounded clay tiles is common in Spanish architecture, as well as in mission or Southwestern style buildings. To maintain Class A fire protection, clay tile must be installed correctly. It is possible for fire embers to penetrate through gaps between the tile and the underlayment.
Concrete Tile
Concrete is another very attractive material to consider if you like tile. Concrete tiles are reliably weather-resistant, non-combustible, and often more cost-effective to use than other tile materials. A wide variety of colors, finishes, and shapes are also available for concrete tiles. When it comes to concrete, you have a greater amount of customization options than when it comes to slate or clay.
Asphalt Shingles
Asphalt shingles make the list despite being petroleum-based while that doesn’t mean that shingles can’t withstand fire. When combined with a fire-resistant underlayment, fiberglass-backed asphalt shingles provide decent fire protection. Asphalt shingles are among the least expensive roofing materials on the market today, which is another reason why so many people prefer them. However, you will need to replace a shingle roof much sooner than you would any type of tile roof if you choose to go with shingles.
Two More Fire-Resistant Materials That Are Even Better
Even though tile and shingles have many benefits, there are two other roofing materials that are even more beneficial. Both materials provide Class A fire protection, and they also offer an impressive style, durability, and little ongoing maintenance:
-
Metal Roofing
When you get right down to it, metal roofing is good. Metal roofing is not only non-flammable, but also lightweight, non-corrosive, and requires very little maintenance. The benefits of metal roofs are many, including their long lifespan, effectiveness in shedding rain and snow, ability to dissipate lightning strikes, and ability to withstand hurricane-force winds. As well as having the ability to cover roofs of any pitch, metal can be used on roofs with slopes ranging from very steep to very shallow.
-
Synthetic Roofing
Synthetic or composition shingles come in a wide variety of colors and textures that mimic wood, asphalt, and natural tiles, and their highly reflective properties can help you save on cooling costs throughout the year. There are many roof tiles that have earned ENERGY STAR certifications, such as DaVinci Cool Roofs. The material is very durable and comes with a 50-year warranty. They are also rated Class A for fire resistance!
