In recent years, pressure has been placed on asphalt shingle manufacturers to upgrade their products' performance in all areas. This pressure has come primarily from insurance companies, municipalities and other agencies such as Factory Mutual, Underwriters Laboratories (UL) Inc. and Florida's Miami-Dade County.
In particular, asphalt shingles' high-wind resistance has taken on added importance in the roofing industry to meet more stringent uplift requirements. In response to this, roofing material manufacturers have made changes to their designs, raw materials, application methods, adhesives used to bond laminates used in individual dimensional shingles and adhesives used to seal shingles to shingles for more wind-resistant roof systems.
High-wind-resistant shingles use a combination of design features and special attachment procedures.
