About
Alexander's Roofing has been servicing commercial roofs across San Antonio, TX since 1980 — over 45 years of continuous operation under the same owner, David Alexander, who personally inspects every project. For facility managers and property owners managing flat and low-slope commercial roofs in Bexar County, that kind of institutional continuity is rare and operationally valuable. Alexander's handles the full spectrum of commercial flat roof work, including modified bitumen systems, TPO membrane installation and repair, built-up roofing (BUR), roof coatings, EPDM rubber membranes, and metal roofing. Their commercial service menu covers new installations, commercial roof repair, preventive maintenance programs, and full roof replacements — making them a practical single-vendor option for office buildings, retail centers, warehouses, industrial facilities, multifamily properties, and mixed-use developments throughout the San Antonio metro. A key operational differentiator for facility managers: Alexander's uses no subcontractors. Every crew member is a direct employee, which reduces quality-control variability and simplifies accountability on multi-phase projects. David Alexander still goes on roofs himself, not just for inspections but to work alongside his crews. The company backs all installations with a 10-year workmanship warranty layered on top of applicable manufacturer material warranties — a meaningful protection for commercial property owners managing long-term capital expenditure planning. Alexander's also handles insurance claim documentation directly, coordinating with adjusters on storm damage and hail events, which reduces administrative burden on facility management teams. Written estimates are provided for every project, and commercial timelines are communicated upfront. With an A+ BBB rating and a client base spanning multiple generations of San Antonio property owners, Alexander's Roofing represents a vetted, locally grounded option for commercial roofing procurement in south-central Texas.
