Roofing Company in San Antonio, TX - Family-Owned Since 1980
When you call Alexander's Roofing, you reach a family-owned San Antonio roofing company that has been serving local homes and businesses since 1980. Our team is focused on doing one thing well: honest, durable roofing for residential and commercial properties across Bexar County. No subcontractor shuffle. No corporate sales script. No storm-chasing pitch.

For more than 45 years, Alexander's Roofing has inspected, repaired, and replaced thousands of roofs across San Antonio. 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 roof repair, roof replacement, or emergency roof repair after a hailstorm, you are calling the same local company that has been showing up with the right crew, the right materials, and a reputation built over decades.
Why Alexander's Is Different
For over 40 years, Alexander's Roofing has built its reputation on one principle: do the work right, know the customer, and stand behind every roof.
Founded in San Antonio and still locally operated, Alexander's Roofing has stayed focused on dependable roofing work instead of turning into a high-pressure sales operation. Our experienced inspectors and crews know the roof systems used across this area, from shingle homes and tile roofs to flat commercial buildings. The company has helped restore homes after major storms, supported large local rebuilding projects, and earned the trust of San Antonio property owners one roof at a time.
The Generational Trust
Today, Alexander's Roofing has worked on the homes of two and sometimes three generations of San Antonio families. That is not a marketing slogan. That is what happens when a local roofing company keeps doing the same job, the right way, in the same city for more than 40 years.
Alexander's has never gone corporate. No venture capital. No shortcuts. Just a dedicated local roofing team, experienced crews, and a company name that has to stand behind every job.

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.
