Signs You Need a New Roof

Knowing when to replace prevents costly water damage.

Visual Signs

Missing, cracked, or curling shingles. Excessive granule loss in gutters. Moss or algae growth indicating moisture issues.

Structural Signs

Sagging roofline (serious structural issue). Daylight visible through attic roof boards. Soft spots when walking on roof indicate rot.

Age-Related

Asphalt shingle roofs over 20 years are approaching end of life. Rising energy bills suggest failing insulation. Neighbors replacing similar-age roofs is a clue.

Water Signs

Ceiling/wall stains, peeling paint near roofline, mold in attic, wet insulation. Multiple or recurring leaks suggest replacement over patching.
