7 Critical Warning Signs Roof Needs Replacement Savannah GA

Key warning signs include: shingles curling, buckling, or missing; heavy granule loss in gutters; daylight visible through the attic; sagging roof deck; recurring leaks after repairs; dark streaks from algae growth; and a roof age over 20 years. If you notice two or more of these signs, schedule a professional inspection.

In Savannah's coastal climate, asphalt shingle roofs typically need replacement at 20–25 years, though some fail earlier due to storm damage or poor ventilation. Metal roofs last 40–60 years. Age alone isn't the deciding factor — condition matters more. A well-maintained 22-year-old roof may outlast a neglected 15-year-old one.

Repairs make sense when damage is localized (less than 30% of the roof), the roof is under 15 years old, and the underlying decking is sound. If repairs are needed across multiple areas, the roof is over 20 years old, or you're spending more than 30% of replacement cost on cumulative repairs, replacement is the better investment.

For a standard 2,000 sq ft home with architectural shingles: $11,000–$17,000 depending on brand, complexity, and any decking replacement needed. Metal roofing runs $18,000–$28,000. Factors that increase cost include steep pitch, multiple stories, extensive decking rot, and complex rooflines with many penetrations.
