TPO (Thermoplastic Olefin) roofing is a popular single-ply membrane known for its durability and heat-reflective properties, but it’s not designed with granules like asphalt shingles, so granule loss specifically relates to other roofing types rather than TPO. However, if you’re seeing granule loss on a roof installed with granule-surfaced shingles, it usually happens because of weather exposure, aging, hail, or poor-quality installation or materials. Granules protect the shingles from UV rays and help with fire resistance, so losing them can lead to faster wear and leaks. For TPO, issues to watch for include surface degradation, small punctures, or seam problems, but these aren’t linked to granule loss. If you notice any unusual wear on your TPO or shingles, checking for wrinkles, bubbles, or exposed fabric in TPO or bare spots on shingles can help you identify early signs.
For a simple DIY check, carefully inspect your roof from the ground or a ladder if safe, looking for any bald spots or thin areas where granules are missing or any tears and punctures on TPO sheets. Cleaning debris gently without harsh tools can help prevent further damage. It’s important not to walk on the roof too much to avoid causing additional wear. If you do spot any damaged areas or excessive granule loss, it’s a good idea to call a professional roofer who can perform a thorough inspection and suggest a fix, whether that’s applying a coating, replacing sections, or addressing underlying issues. When talking to a contractor, ask how they will ensure the repair maintains your roof’s warranty and what specific materials or techniques they use for granule loss or TPO membrane repairs. This helps you ensure quality and long-term protection for your roof.
