Selecting A Roofing Product Part Part 3 What Does The UL Fire Resistance Rating For A Shingle Mean?

What does the UL fire resistance rating for a shingle mean?

The Underwriters Laboratories Inc. (UL) ratings signify that the shingles were manufactured to pass a certain set of standards to qualify as fire resistant.  Organic shingles carry a UL Class C fire resistance rating.  Fiber glass shingles carry a UL Class A fire resistance rating.  Either is appropriate for residential applications.   Some local building codes may have ordinances specifying a certain UL Class for your residential area.  Your roofing contractor or local building codes officer can tell you what the requirements are for your particular area.
