We're a family-owned roofing company in San Antonio, TX, focused on doing one thing well: honest, durable roofing for homes and commercial buildings across Bexar County. No subcontractors. No corporate sales reps. No storm-chasing pitch.
David started this business 45 years ago and has personally inspected, repaired, and replaced thousands of San Antonio roofs since. We handle everything from a single shingle leak to a full commercial flat roof system. If you need a trusted San Antonio roofing contractor for a repair, replacement, or emergency roof repair in San Antonio after a hailstorm, we're the same crew that's been showing up - on time, with the right materials - since the year your parents' first roof was new.
Why Alexander's Is Different
For over 40 years, David Alexander has built his reputation on one principle: do the work himself, know every customer by name, and stand behind it forever
Born and raised in San Antonio, David started in roofing when he was young and never stopped. While other companies scaled into corporations, David kept Alexander's small, focused, and personal. He personally meets every customer. He still goes up on roofs himself—not just to inspect, but to work. When Hurricane Katrina hit, David was there helping restore Beaumont homes. When the city needed expertise rebuilding the Stockyard and other key infrastructure, they called Alexander's Roofing.
The Generational Trust
Today, David has worked on the homes of two—sometimes three—generations of San Antonio families. That's not a marketing slogan. That's what happens when you've been doing the same job, the same way, for 40+ years in the same city.
Alexander's has never gone corporate. No venture capital. No shortcuts. Just David, his dedicated crews, and his word.
Full Roof Replacements - When repairs aren't enough, Alexander's handles complete roof replacement in San Antonio with 10-year workmanship warranties and next-day inspections.

Roofing Expertise
Roofing in San Antonio Takes Local Knowledge — 45 Years of It
San Antonio's climate is hard on roofs. The combination of 100+ degree summers, sudden hail storms, and intense UV exposure means roofing materials break down faster here than almost anywhere else in the country. We've been fixing, replacing, and maintaining roofs through all of it since 1980.
Hail damage is a regular event in San Antonio
Our storm season can bring multiple hail events in a single year, and we've responded to hundreds of emergency calls across the city. We know how to document damage for insurance claims so the full scope gets covered, not just the visible damage.
Clay tile and concrete tile roofs are everywhere in San Antonio
Neighborhoods like Alamo Heights, Terrell Hills, Monte Vista, and the North Side are full of tile roofs that require specialized installation and repair techniques. We've been working with clay tile and concrete tile roofs since David started the company.
Flat commercial roofs across San Antonio's business districts
need materials that can handle Texas heat without cooking the building underneath. We install and maintain TPO roofing, modified bitumen, and gravel built-up systems designed for this climate.
The heat itself is the silent roof killer
Thermal cycling, hot days followed by cooler nights, causes shingles to crack, tiles to shift, and flat roof seams to pull apart. Regular inspections catch these problems before they become leaks. We offer free roof inspections because catching problems early saves our customers thousands of dollars.
