St. Louis County encompasses over 90 municipalities and numerous unincorporated communities, making it the most populous county in the State of Missouri. From the historic inner-ring suburbs like Kirkwood, Webster Groves, and Clayton to the established communities of south county and the growing western suburbs of Ballwin, Wildwood, and Town and Country, the county offers an extraordinary diversity of housing stock spanning more than a century of construction.
Gallagher Bros Construction has been serving homeowners and businesses throughout St. Louis County since 1973, building deep expertise across every neighborhood and housing type in the region.
The diversity of St. Louis County’s housing stock means roofing needs vary dramatically from community to community. Inner-ring suburbs feature homes from the early 1900s with complex roof lines and sometimes historic materials, while mid-county neighborhoods contain the mid-century ranch homes and split-levels that form the backbone of the area’s residential roofing demand. Western suburbs often feature newer, larger homes with premium materials and significant square footage. Throughout the county, St. Louis’s severe weather patterns bring regular hail, wind, and storm damage that drives both planned replacements and emergency repairs. As a contractor with over 50 years of experience in St. Louis County, Gallagher Bros Construction understands the specific needs of each sub-market.
