Asphalt Shingle Roofing for High Wind Regions HOME BUILDER’S GUIDE TO COASTAL CONSTRUCTION Technical Fact Sheet No. 7.3 Purpose: To recommend practices for installing asphalt roof shingles that will enhance wind resistance in high-wind, coastal regions. Key Issues n Special installation methods are recommended for asphalt roof shingles used in high-wind, coastal regions (i.e., greater than 90-mph gust design wind speed). n Use wind-resistance ratings to choose among shingles, but do not rely on ratings for performance. n Consult local building code for specific installation requirements. Requirements may vary locally. n Always use underlayment. See Fact Sheet No. 7.2 for installation techniques in coastal areas. n Pay close attention to roof-to-wall flashing and use enhanced flashing techniques (see Fact Sheet No. 5.2). Construction Guidance 1. Follow shingle installation procedures for enhanced wind resistance. 7.3: ASPHALT SHINGLE ROOFING FOR HIGH WIND REGIONS HOME BUILDER’S GUIDE TO COASTAL CONSTRUCTION 1 of 3 12/10 ROOFING 7
