When a roof can account for as much as 40% of
the average home's exterior, many factors weigh into the choice of
materials. Some surfaces are more beautiful than others. Some offer
greater resilience or endurance. Some are more affordable. But the one
roofing surface which offers all those attributes in balance is the asphalt
shingle.
Now accounting for about 80% of the
residential roof surfacing in the United States, asphalt shingles are
measured against a variety of standards that evaluate fire and wind
resistance, tear strength, and other key performance indicators. For fiber
glass shingles, ASTM D3462 is considered the most important.
This comprehensive standard covers tear
strength, nail-pull resistance and pliability, among other shingle
characteristics.
Over 20 CertainTeed fiber glass shingles are
independently certified by Underwriters Laboratories to meet the tough ASTM
D3462 standard.
