What should Marietta homeowners know about metal roof repair?
Short answer. In Marietta, most metal roof repairs come down to worn fasteners, opened laps, failed wall and chimney flashing, or storm and limb damage, and the right fix is targeted replacement of those parts rather than a blanket coating. Before work starts, confirm whether your address falls under the City of Marietta or unincorporated Cobb County for permits, and get photos and a written scope from the contractor.
Local factors
- Mature trees. Many Marietta neighborhoods sit under heavy oak and pine canopy. Falling limbs dent panels and tear trims, and leaf litter holds moisture against the metal.
- Storms. Cobb County gets the same spring and summer severe thunderstorms and hail as the rest of metro Atlanta, which loosen trims and damage fasteners and panels.
- Older homes with metal porch roofs. Many older Marietta homes have metal porch or accent roofs with aging flashing where they meet brick or siding.
- Mixed roofs. Many homes pair a shingle main roof with metal accents, and leaks often sit at the transition between the two.
Permits and approvals
A Marietta mailing address does not always mean City of Marietta jurisdiction; some addresses fall under Cobb County. Check which building department covers your property before work that may need a permit. Homes in local historic districts or HOAs may need design approval for changes to roofing material or color.
Getting a solid repair
- Ask for photos of the failure and an explanation of why it leaked.
- Get a written scope listing fasteners, laps, trims, closures and any panels to be replaced.
- Insist on matching metal and compatible fasteners, with no copper or lead touching steel panels.
- Be wary of whole-roof coatings as the first answer to a single leak.
- If the damage followed a storm, photograph it before repairs, since it may be covered depending on your policy.
