Which roofing materials are the most fire retardant?
Not only do roofing materials need to be able to withstand adverse weather conditions, they also need to be able to withstand the heat of a fire in the event of an emergency. There are a number of roofing materials, all with varying levels of fire resistance, each classified by specific fire ratings so they can be easily identified.
These are a few of the most common roofing materials alongside their classification of fire resistance:
Even under extreme heat from flames, metal does not ignite. And with the addition of a fire-resistant barrier it earns a Class A certification. The range of metal roofing materials is diverse; copper, steel and zinc are some options available with varying aesthetic differences available to constructors. Metal alloys are another option. Alloys are a mixture of separate metals to give varying benefits depending on location.
Not only do metal tiles provide great fire resistance, they are also non-corrosive, giving them a longevity guarantee that far exceeds other materials.
Slate has been used for roofing solutions for centuries. The natural material is inherently resistant to fire and is also awarded a Class A rating. There are different types of slate that are available, some can be used for flooring or walls, but the slate used for roof tiling is slightly different; it is thicker and heavier than other tiles and it is this thickness which helps it earn its Class A rating as thick slate cannot be easily chipped and penetrated by fire.
Although slate is a more expensive roofing option, the material itself is perfect for roofing and can last a very long time. Some historic buildings fitted with slate roofs have lasted more than 70 years without the benefit of modern building techniques.
A lot of residential homes make use of clay or concrete tiles. They are heavy, durable, fireproof, and affordable and have become one of the safest roofing covers available. Clay not only resists flames but can easily dissipate heat evenly and quickly. Properly installed they also achieve a Class A rating. Although not as durable as slate tiles, clay tiles can easily last upwards of 30 years thanks to modern manufacturing methods.
