Top Signs It's Time to Replace Your Roof: Advice from Blackstone Experts Jul 18, 2025

As homeowners, recognizing when it's time to replace your roof can save you money, protect your investment, and ensure your family’s safety. At Blackstone Roofing & Construction LLC, we often field questions from clients unsure if their roof needs repair or full replacement. Here, we break down the key signs that indicate it’s time to replace your roof.

The age of your roof is one of the most telling indicators. Most asphalt shingle roofs last between 20 to 25 years. If your roof is approaching this age range, it’s time to start considering replacement options. The longevity of your roof also depends on whether the old shingles were removed and if it's properly ventilated.

Next, inspect your shingles for curling or buckling. Shingles that are curling or losing granules are clear signs that your roof is nearing its life expectancy. Watch for shingles on slopes that are directly exposed to sunlight, as they are prone to deteriorate faster due to the intense heat.

Another sign to look for is roof valleys. Snow and rain flow through valleys into gutters, so if your valley is compromised, you may be susceptible to leaks. Missing or damaged shingles in these areas require immediate attention. Roof valleys are critical points for the overall integrity and functionality of your roofing system, making their maintenance paramount.

Your chimney flashing also plays an essential role. If your chimney flashing consists of roof cement or tar, you'd need to replace it with a long-term, water-tight fitting metal flashing system. This upgrade is crucial in preventing water leakage and maintaining your roof’s integrity.

Gutters piling up with shingle granules are another point of concern and often suggest the need for a roof replacement. As a roof ages, the granules from shingles deteriorate and accumulate in your gutters. Check for inconsistencies in the granule distribution on your shingles, you may notice darker spots.

Sunlight penetrating through roof boards is a definite indicator that a replacement is necessary. Climb into your attic on a bright day and look up. If sunlight comes through the roof boards, you should inspect your roof immediately.

Sagging roof boards should also not be overlooked. A droopy, sagging roof can signify severe structural problems and indicates that a replacement is not just an option, but a necessity. There could be a potential problem with decking in the attic, possibly due to moisture build-up over time.
