Homeowners can differentiate between normal wear and tear and signs that a new roof is needed by carefully observing the condition of their roofing materials and the home's interior. Normal wear might include minor discolorations or small amounts of granules in gutters. In contrast, significant indicators like curled or missing shingles, visible leaks, or daylight showing through the attic suggest urgent need for replacement. Timely professional inspections can help distinguish between these conditions, ensuring that issues are addressed before they escalate into more severe damage.
