If you are getting roof replacement quotes in Savannah, you will encounter two main categories of asphalt shingles: three-tab and architectural. The price difference is real — but so is the performance difference, and in coastal Georgia's climate, that performance gap matters more than most places.
Quick Comparison

| Weight | ~200 lbs/square | ~300 lbs/square |
| Wind Rating | 60-70 mph | 110-130 mph |
| Lifespan (Savannah) | 12-16 years | 20-25+ years |
| Cost (installed) | $2.50-$3.50/sq ft | $3.50-$5.00/sq ft |

Why Three-Tab Is Disappearing
Three-tab shingles dominated American roofing for decades. They are thin, flat, uniform — and that is the problem. In Savannah's climate:
- • Wind vulnerability: 60-70 mph wind ratings do not cut it in a hurricane zone. Architectural shingles are rated for 110-130 mph because they are heavier and use stronger adhesive strips.
- • Shorter lifespan: The thin profile means less asphalt to protect against UV and moisture. In our heat and humidity, three-tabs fail 30-40% sooner than architectural.
- • Insurance complications: Some Georgia insurers are now refusing to write policies on homes with three-tab shingles, or charging significantly higher premiums.
- • Resale impact: Homebuyers and inspectors view three-tab as outdated. An architectural roof adds measurable resale value.
The Cost Math
2,000 sq ft Savannah Home (typical)
- • Three-tab installed: $7,500-$10,000
- • Architectural installed: $10,500-$15,000
- • Price difference: $3,000-$5,000
- • Extra lifespan: 8-10 years
- • Cost per extra year: $300-$625/year
Our Recommendation
We strongly recommend architectural shingles for every Savannah home. The wind protection alone justifies the upgrade — and the longer lifespan means it actually costs less per year than three-tab. Options like GAF Timberline HDZ or Atlas StormMaster provide 130-150 mph wind ratings that coastal Georgia demands.
