Granule loss has become an increasingly common concern among roofing contractors, particularly with shingles manufactured and installed following the COVID-19 pandemic. Contractors have reported instances of excessive granule shedding on relatively new roofs, resulting in homeowner complaints, warranty claims, and disputes over whether the condition constitutes a manufacturing defect or improper installation.
Asphalt shingles contain mineral granules that protect the underlying asphalt from ultraviolet exposure and weathering. Some granule loss is normal, particularly during transportation, installation, and the initial period following installation. However, excessive or premature granule loss may indicate a manufacturing defect, particularly when it exposes the underlying asphalt or affects the performance of the shingles.
Because installing contractors generally have no control over the manufacturing process or granule adhesion, roofing contracts should distinguish between normal granule shedding, manufacturing defects, and installation deficiencies. Contractors should also direct product-related warranty claims to the manufacturer while preserving their responsibility for workmanship.
Recommended Contract Provision
Granule Loss Disclaimer. Owner acknowledges that some granule loss or shedding is a normal characteristic of asphalt shingles, particularly during and following installation, and as a result of ordinary weathering and aging. Contractor does not manufacture the shingles and makes no independent warranty regarding granule adhesion or retention. To the fullest extent permitted by law, Contractor disclaims liability for any excessive or premature granule loss (“Loss”). The Loss shall be governed exclusively by the manufacturer’s written warranty, which shall constitute Owner’s sole and exclusive remedy against Contractor for such product defects.
