Gutters With a Roof Replacement

A roof replacement is the easiest time to deal with gutters. The roof edge is already open, the drip edge is being replaced, and fascia problems are visible. Replacing or rehanging gutters during the roof job usually costs less than a separate visit and produces a cleaner edge detail.

Here is how to decide whether to replace or reuse existing gutters.

Replace when

Gutters are sectional and leaking at seams, sagging or pulling away, dented or rusted, or undersized for the roof area, which shows up as overflow even after cleaning. Rotted fascia behind the gutter means the gutters have to come down anyway. Adding gutter guards is easier on new gutters.

Reuse when

Newer seamless gutters that are straight, pitched correctly and draining well can be removed and rehung after the new drip edge goes on. The key detail is that the drip edge extends into the gutter so water does not run behind it and rot the fascia.

Sizing and downspouts

Steep roofs and long runs collect a lot of water in heavy Georgia storms. Many homes benefit from 6-inch gutters and 3-by-4-inch downspouts instead of the 5-inch and 2-by-3 standard. Downspouts should discharge well away from the foundation.

Costs

Published 2026 estimates put seamless aluminum gutters at about $9–$13 per linear foot installed. Fascia repair, guards and larger downspouts add cost. Including gutters in the roof contract simplifies scheduling and responsibility.

Permits and HOA

Gutter replacement is not listed as needing a building permit in Johns Creek's checklist; a roof replacement without structural work and with no more than 32 square feet of decking is also listed as not needing one. HOAs may regulate gutter color.

Gutter guards and maintenance

Guards reduce how often gutters need cleaning under the oaks and pines common in Johns Creek, but none are maintenance-free. Ask how a guard handles pine needles, which slip through some screens, and whether it affects the shingle warranty if it slides under the first course. Plan on checking gutters at least once or twice a year either way.
