What can void asphalt shingle wind warranties?

Installation deficiencies can void asphalt shingle wind warranties because proper installation is critical for the performance and longevity of the roofing system. Manufacturers provide specific guidelines and standards that must be followed for the shingles to function as intended, especially for resisting wind damage. If the shingles are not installed correctly—such as improper fastening techniques, inadequate overlap, or failure to follow manufacturer instructions—the warranty may be invalidated.

Each shingle system is designed to perform under certain conditions, and deviations in installation can lead to premature failure or damage, which the warranty would not cover if they were not adhered to. Therefore, it's essential that professional installers follow all manufacturer specifications to ensure the validity of the warranty.
