Photo 1: Research studies conducted: 1) unsealed shingle surveys; 2) full-scale wind tunnel tests; 3) in situ mechanical uplift tests on naturally aged shingle roofs; 4) shingles artificially aged then tested for uplift capacity; 5) measurements of wind-induced forces on the sealant strips of fully sealed and partially unsealed shingles
Photo 2: Location of partially/fully unsealed three-tab and laminate shingles (tape marks)
Photo 3: Blown-off three-tab asphalt shingles were observed in Hurricane Katrina in 2005 and Hurricane Ike in 2008.
Photo 4: These are typical partially unsealed ridge and hip shingles found during
roof surveys in Florida. The edges frequently were unsealed with an adhesive failure
plane while the folded portion was sealed.
Photo 5: Characteristic hip shingle blow-off patterns from left to right: 0-degree
wind direction, 45-degree wind direction and 90-degree wind direction
Photo 6: These blown-off shingles were initiated by a corner shingle that pulled
through the corner fastener. Blow-off progressed across the roof as the wind test
continued and wind speeds increased. The location of fasteners was not within the
Asphalt Roofing Manufacturers Association's 2006 Asphalt Roofing Residential Manual
Asphalt roofing shingles represent about 80 percent of the residential roofing market.
