Tab shingles are a common type of asphalt shingle, notable for their rectangular shape and cut-out tabs that create the classic shingle pattern on a roof. Granule loss happens when the small, colored particles embedded in the shingle surface begin to fall off, sometimes exposing the underlying asphalt layer. This can result from prolonged sun exposure, severe weather, hail, or simply the roof aging over time. You might notice granules accumulating in gutters or at the base of downspouts, or shingles appearing dull or bare in spots. A simple DIY check involves gently brushing a few shingles to see if granules come off easily or inspecting the gutter for granule sediment after rain. Also, look for curling, cracking, or missing tabs that signal wear beyond just granule loss. If these issues are widespread or if you detect water stains inside the home, it’s time for a professional inspection.
Calling a roofer is critical when granule loss is significant since it reduces the shingle’s ability to protect your roof from UV rays and weather, ultimately shortening its lifespan. When contacting a contractor, ask if the granule loss is due to normal wear or a deeper underlying issue that might void your roof warranty. Another useful question is how they plan to address any protective coatings and whether the shingle manufacturer’s guidelines for repairs or replacements will be followed, ensuring your warranty remains valid. A qualified roofer can recommend whether spot repair, partial re-roofing, or full replacement is the best fix, all while considering the long-term health of your roof and your budget.
