A homeowner files a warranty claim 8 years after installation, reporting widespread shingle cracking. The GAF-certified contractor inspects and finds the attic has been converted to living space with no insulation above, causing extreme heat buildup. How does this affect the claim?
-
A
GAF's warranty covers all cracking regardless of attic conditions
-
B
The warranty may be denied because inadequate ventilation due to attic conversion voids coverage
-
C
The claim is valid since 8 years is within the coverage period
-
D
The claim falls to the homeowner's insurance automatically
