Fiberglass shingles are a common roofing material known for their balance of durability and affordability. Typically, the lifespan of fiberglass shingles ranges from 20 to 30 years, though this can vary depending on the quality of the product, installation, and local weather conditions. The shingles consist of a fiberglass mat coated with asphalt and mineral granules, which help protect against sunlight and water damage. Over time, exposure to the elements causes the shingles to lose granules, crack, or curl, which signals aging or deterioration. Simple DIY inspections include checking your roof for missing granules in gutters or downspouts, looking for uneven or damaged shingles, and noting any signs of leakage inside your attic. These visual checks can help you identify when the roof might need professional attention.
If you’re unsure about the condition of your fiberglass shingles or if you detect early wear, it’s smart to call a qualified roofer to conduct a thorough inspection. A professional can assess if repairs are necessary or if replacement is the better option, especially since improper handling can void your shingle warranty. When talking to a contractor, ask how long they expect the current shingles to last under your regional weather conditions and inquire whether their recommendations comply with local building codes and warranty terms. Additionally, it’s helpful to discuss the roofer’s experience with fiberglass shingles specifically, as installation quality significantly affects longevity and performance.
