What are signs your roof needs replacing soon?

Your roof likely needs replacing if you notice missing, curling, or cracked shingles, as these expose the underlying structure to water damage. Granules collecting in your gutters indicate shingles are deteriorating. If your roof is 20 to 30 years old, it's approaching the end of its typical lifespan regardless of appearance. Inside the house, look for water stains on ceilings or walls, daylight visible through the attic, or sagging areas in the roof deck. Moss or algae growth can signal trapped moisture breaking down shingles. If you're making frequent repairs or notice your energy bills rising due to poor insulation, replacement is likely more cost-effective than continued patching.
