The granules on your asphalt shingles are a critical component of the roofing system. Apart from their cosmetic value, asphalt roofing granules safeguard the integrity of your shingles from the environment, particularly ultraviolet (UV) radiation. While there are some situations in which granule loss is expected and acceptable, in other cases it can signal the need for prompt roof repair or replacement.

Today, The Thomas Roofing Company, a professional roofing contractor, explains when and why loose asphalt granules are a cause for concern.
- Granule Degradation Results in Water Damage. Leakage occurs most commonly in bald spots left on your shingles after the granules have fallen off. Water damage causes ceiling discoloration, shingle curling and attic ventilation concerns. A professional roofer should repair this problem.
- Granule Degradation Is a Symptom of Roof Failure. Your roof is only as robust as the materials its built with. When the granules on your asphalt roof begin to fall off, the roof’s defense against the elements becomes impaired. Preserve the structural integrity of your home by contacting roof and gutter installation experts for prompt shingle replacement.
- Granule Loss Results in Inadequate Weather Defense. Loose granules compromise your roof’s ability to withstand severe weather. This is especially true if you live in an extreme climate. This is why you should speak with expert roofers to determine which asphalt shingle products are most suited to your area’s climate.
- Granule Loss Results in an Unsightly Exterior. Granule loss can also affect the appearance of your exterior. The bald patches or incorrect shingle colors caused by re-roofing can drag down your home’s curb appeal, reducing its value.
