No guard can fix a gutter that sags, leaks or tilts the wrong way. Ask the company to look over the pitch, seams and hangers first and to show any repairs as separate line items. If the gutters are worn out, ask for a second price on new gutters with guards installed at the same time.
In the city’s five local historic districts, the preservation ordinance never mentions gutters, but it does require approval before any material change to a house’s appearance. Call the city’s historic preservation staff at 678-553-6596 before adding a guard that would alter how the roof edge looks.
Each written quote should name the guard type and material, the feet measured, the installed price per foot, and any cleaning or repair work. Ask how the guard is attached. Some sit inside the gutter, some fasten to the gutter lip or fascia, and some slide beneath the first row of shingles, a method cost guides warn can affect a roof warranty.
Ask how often the guard will need clearing beneath the trees on your lot, and whether the manufacturer’s warranty requires a professional install. Then ask for proof of liability insurance, because a SirGutters listing reflects what a company says about itself online, with no check of licenses or coverage.
