Brentwood is one of St. Louis’s most desirable inner-ring suburbs—a walkable community with excellent schools, convenient shopping at the Promenade, and a housing stock that ranges from charming 1920s bungalows to mid-century ranches and newer construction. Property values here reflect the quality of life, and your roof is a major part of protecting that investment.
Many Brentwood homes were built between the 1920s and 1960s, which means unique roofing considerations. Steeper pitches on older bungalows. Slate or tile on historic homes. Original wood shake that’s been covered over with asphalt. We’ve worked on every type of roof in this area and understand what each style demands.
When you hire a roofer in Brentwood, you need someone who respects the character of your home—not a crew that slaps on the cheapest three-tab shingles and calls it done. We work with homeowners to select materials that complement their home’s architecture, whether that’s dimensional shingles that mimic the look of cedar shake or premium options that match a neighbor’s historic slate.
Gallagher Bros has been roofing homes across St. Louis since 1973—before Brentwood Promenade existed, before I-64 was rebuilt. We’re not a franchise. We’re not storm chasers. We’re a family-owned company that will still be here when your warranty matters.
Roof Replacement: Whether your 1940s cape cod needs its third roof or your newer home is showing storm damage, we handle complete tear-offs with attention to detail. Every replacement includes deck inspection, proper underlayment, and premium shingles from GAF, Owens Corning, or CertainTeed. For historic homes, we offer specialty options that maintain architectural integrity.
Storm Damage & Insurance Claims: Brentwood isn’t immune to the hailstorms and wind events that sweep through the St. Louis metro. When damage happens, we handle the insurance process from inspection through payment. Our documentation is thorough, our estimates are accurate, and we advocate for homeowners to receive fair compensation.
Roof Repair: Not every issue requires replacement. Flashing failures around chimneys, damaged vent boots, or missing shingles can often be repaired. Older Brentwood homes sometimes have unique repair needs—valleys that collect debris, dormers with tricky flashing, flat sections over additions. We diagnose problems accurately and fix them right.
Gutters, Siding & Windows: Brentwood’s mature trees are beautiful but murder on gutters. We install seamless aluminum gutters and gutter guards to handle heavy leaf and debris loads. We also handle siding and window replacement for complete exterior projects.
Gallagher Brothers Construction serves homeowners throughout Brentwood and the 63144 zip code. Whether you’re near Brentwood Park, the Promenade, Brentwood Forest, or along Hanley Road, we’re ready to help with your roofing project.
We also serve neighboring communities including Clayton, Richmond Heights, Maplewood, Webster Groves, Rock Hill, and Glendale.
