CRACKING THROUGH THE REINFORCEMENT AND BALD SHINGLES ARE SERIOUS DEFECTS
Cracking Through Reinforcement
Depending upon the style of shingle, the normal weathering characteristics described earlier may be a sign of more serious problems. For example, cracks across a typical three-tab shingle may be a sign of a weak reinforcement. This type of cracking threatens the waterproofing integrity of the roof and needs to be addressed immediately. Large areas of granule loss that expose the underlying asphalt place the shingle at risk of premature failure because UV rays can now get to the asphalt layer. In situations in which hail has knocked off large areas of granules, you can expect the life of your shingles to be appreciably reduced due to the effects of ultraviolet radiation from the sun. Shingles with open blisters in which the asphalt becomes visible are also at greater risk for premature failure. This information has been prepared to help you identify normal aging characteristics of asphalt roofing shingles and become more informed. Take the time to determine if the conditions you have observed are serious enough to require immediate action. Should you need some assistance please contact The Defrehn Corporation at 215-860-1000.
