Asphalt shingles are a popular roofing material due to their affordability and ease of installation. However, they are vulnerable to UV degradation over time because the sun’s ultraviolet rays break down the asphalt binder in the shingles. This causes the shingles to become brittle, lose granules, and fade in color, reducing their protective qualities against water and weather. Heat combined with UV exposure accelerates this aging process, especially in warmer climates. Homeowners might notice curling edges, bald spots where granules have worn off, or shingles that crumble when touched. A simple DIY check is to look closely at your roof from the ground with binoculars or binoculars and see if large sections appear faded or have excessive granule loss. During a safe, close-up inspection from a stable ladder, gently running your hand over the shingles can reveal if they are brittle or crumbling, but be cautious not to damage the roof or put yourself at risk.
When you notice signs of UV damage, it’s often time to call a professional roofer for a thorough assessment. A qualified contractor will evaluate whether the shingles can be treated or if a partial or full replacement is needed, especially before your warranty expires. Ask your roofer, “How much of the roof is affected by UV damage, and will patch repairs hold up long term?” and “Are there upgraded shingle options with better UV resistance that fit my budget and warranty requirements?” In some cases, applying roof coatings or sealants can extend the life of shingles, but these fixes are temporary and don’t replace the need for shingle integrity. Always confirm that any repair or replacement work won’t void your existing warranty by checking manufacturer guidelines with your contractor. Early action can prevent leaks and costly damage down the road, so UV damage should never be ignored.
