  Fire Retardant Treated Roofing

Fire treated roof, fire retardant treatment Fire retardant cedar shakes and shingles can be used as an affordable and convenient alternative in many areas where the building code requires flame-resistant roofing materials to be used.

There are three different classes of fire retardant treatments available:

Class "A" Fire Retardant Treatment


This classification uses a Class "B" fire retardant treated product along with a UL (Underwriters Laboratories) rated fire retardant fiberglass cap sheet underlay. A Class "A" product is effective against severe fire exposures. Under such exposures, roof coverings are:

  • not readily flammable
  • afford a fairly high degree of fire protection to the roof deck
  • do not slip from position
  • pose no flying-brand hazard.

Class "B" Fire Retardant Treatment


Class "B" fire retardant treatment is effective against moderate fire exposures. Under such exposures, roof coverings of this class are not readily flammable, afford a moderate degree of fire protection to the roof deck, do not slip from position and pose no flying-brand hazard.

Class "C" Fire Retardant Treatment


A product that is effective against light fire exposures. Under such exposures, roof coverings of this class are not readily flammable, afford a measurable degree of fire protection to the roof deck, do not slip from position and pose no flying-brand hazard.
