UL Fire Ratings

This is the most commonly accepted standard. Created by Underwriters Laboratories, Inc., a non-profit organization dedicated to establishing fire safety standards.

They use the following ratings:

  • Class “A”: The highest fire-resistance rating for roofing indicates that the materials are able to withstand severe exposure to fire if the fire source is outside the building.
  • Class “B”: This fire-resistance rating indicates that the rated roofing materials will withstand moderate exposure to fire if the fire source is outside the building.
  • Class “C”: This rating indicates that the roofing materials limited to withstanding only light exposure to fire if the fire source is outside the building.

Some roofing materials, such as untreated wood, are unrated as they cannot meet even the minimum ratings for fire safety. However, if the wood is treated with fire-retardant chemicals, it can often meet Class B – or even class A – requirements. Underlying material may also be used to boost the roof material rating, but these ratings will specify a “by assembly” qualification.

They utilize a standard fire test to determine the fire rating of roofing material. They look at the ability for flames to penetrate the materials into the attic, how the flame spreads over the entire surface of the roof covering, how it displaces, throws off embers, and other criteria.

In regards to your insurance, materials that fall into Class A are generally afforded better insurance rates. These materials include clay, slate, concrete, asphalt shingles, and metal.

One more thing, new roofing materials are being developed all the time so make sure to research and ask your roofing professional for help when looking at material options for your roof.
