You know it's time to replace a roof when you see curled or missing shingles, granules in the gutters, or daylight through the roof boards. After 20-30 years, most asphalt shingles just wear out. Look for dark spots inside, especially after rain, or sagging areas that feel soft underfoot. A professional inspection every year can catch problems early, but once you have persistent leaks or significant moss growth, replacement is the practical fix.
