Our Coastal Georgia Recommendation
For most Savannah-area homeowners: Atlas Pinnacle Pristine ($$) is our top pick. The lifetime algae warranty alone makes it worth the investment in our humid climate, and the HP42 upgrade to 150 mph wind is available for high-exposure homes.
If hail protection is your #1 concern: IKO Cambridge ($$) gives you Class 3 impact at the same price tier as Atlas Pinnacle Pristine — the best impact value on the market.
If curb appeal is paramount: OC TruDefinition Duration ($$$) has the most vibrant color technology and SureNail's patented wind performance. Worth the premium for high-end homes.
