Savannah sits on the Atlantic coast of Georgia at the mouth of the Savannah River, and the roofing environment combines direct hurricane exposure with one of the most rigorous historic preservation regimes in the country. The Savannah Historic District covers the original city grid and much of the surrounding older neighbourhoods, and any exterior work triggers review through the Savannah Historic Review Board — with material and profile requirements that predate and constrain standard roofing choices.
Hurricane season is the seasonal anchor. Every named storm crossing the Southeast passes close enough to matter, and Matthew in 2016 and Irma in 2017 both brought significant wind and coastal impact to Chatham County. Between storms, salt air off the marshes and the river accelerates corrosion on every metal component, and near-constant humidity produces algae on shaded slopes.
Historic Review Board approval is a precondition
The Savannah Historic Review Board reviews all exterior work on historic-district parcels before the permit will be issued. Slate, standing-seam metal, and specific historic tile profiles are frequently required over asphalt substitutes. A local Savannah contractor working these districts will know the process; an out-of-area crew will not.
High-wind fastening is code
Coastal Georgia code requires enhanced fastening. Six nails per shingle in the double-thickness zone, proper starter courses, and hip-and-ridge shingles rated for the wind class of the field are code baselines — not upgrades.
Salt-air corrosion is aggressive here
Marsh-adjacent and river-adjacent homes across historic Savannah, the Isle of Hope, and Tybee-area properties see accelerated corrosion on flashings, drip edges, and any exposed metal component. Coated stainless, copper, or ZAM-coated flashing is worth specifying — cheap fasteners will rust-streak a good roof within a few years in this environment.
Named-storm deductibles are percentage-based
Coastal Georgia policies apply a hurricane deductible as a percentage of dwelling coverage — often 2 to 5 percent. Reading the declarations page before hurricane season is essential.
Slate is a specialist trade in Savannah
The historic slate roofs across the Historic District can outlast the buildings when maintained correctly. Slate failure is almost always the copper flashing or the fastening — not the slate itself. Quotes should name the slate origin, fastening approach, and flashing spec.
Savannah permits
The City of Savannah Development Services Department issues re-roof permits, with Historic Review Board approval preceding permit issuance in historic districts. Both should appear as line items on the written quote.
