Best Choice for Coastal Georgia
Humidity-prone areas (Savannah, Pooler, Richmond Hill): Atlas Pinnacle Pristine dominates with its lifetime 3M Scotchgard algae warranty. In our humid climate, algae streaks appear on unprotected roofs within 5-7 years — Atlas prevents this permanently.
Hail and storm zones: IKO's Dynasty (Class 3) and Nordic (Class 4) provide superior impact protection with potential insurance discounts of 20-35%.
Our recommendation: For most Coastal Georgia homeowners, Atlas Pinnacle Pristine offers the best long-term value. If you're in a hail-prone area or want maximum impact protection, IKO Nordic is the better investment.
