Why Affton Homeowners Choose Gallagher Bros
Affton is the heart of South County—a tight-knit community with tree-lined streets and well-maintained homes, many built in the 1950s through 1970s. These classic ranch homes and split-levels have solid bones, but roofs from that era are long past their lifespan. Even homes re-roofed in the 1990s are now due for replacement.
Our South County headquarters at 500 S South County Center Way is literally in your backyard. We’re not a company that swoops in after a storm and disappears—we’ve been part of this community for over 50 years. Our trucks are on Gravois and Mackenzie every day. Our crews live in Affton, Mehlville, and Oakville. When something goes wrong, you know where to find us.
Older homes often have unique roofing challenges: multiple layers of shingles that need removal, outdated ventilation systems, or original decking that needs inspection. We’ve seen it all, and we approach every job with the care it deserves—no cutting corners, no skipping steps.
Whether you’re dealing with storm damage, an aging roof, or a leak that just won’t quit, Gallagher Bros delivers the same quality workmanship we’ve been providing to South County families since 1973.
Roofing Services for Affton & South County
Roof Replacement for Older Homes: Many Affton homes are on their second or third roof. We handle complete tear-offs, including removing multiple shingle layers if needed. Every replacement includes a thorough inspection of the underlying deck, replacement of damaged plywood, and installation of proper ice and water barriers. We use premium shingles from GAF, Owens Corning, and CertainTeed.
Storm Damage Restoration: South County gets hit by the same hailstorms and wind events as the rest of the St. Louis metro. When your roof takes damage, we handle the insurance claim process from initial inspection through final payment. Our documentation is thorough, our communication is clear, and we fight to get you the coverage you deserve.
Roof Repair: Sometimes you don’t need a full replacement—just a targeted repair to stop a leak or replace wind-damaged shingles. We provide honest assessments. If a repair will solve the problem and buy you more years, that’s what we’ll recommend.
Gutters, Siding & Windows: Your roof doesn’t work alone. Clogged gutters cause water damage. Aging siding lets moisture into your walls. We handle complete exterior projects, and bundling services often makes financial sense.
