Best Flat & Low-Slope Roofing Contractors in San Antonio

Santex Roofing is one of San Antonio’s longest-operating independent roofing firms, founded in January 1983 by the Lopez family and still operating as a sole proprietorship under Alonso Lopez Jr. and Michelle Lopez. Their BBB A+ accreditation date of April 14, 2005 gives them one of the oldest continuously-held BBB accreditation records among San Antonio residential and commercial roofers. Over 43 years, they have developed deep expertise across the full roofing spectrum: composition shingles, standing seam metal, modified bitumen (hot tar and cold process), and wood shake. Their classification as both a roofing contractor and a metal roofing contractor reflects a genuine specialty in alternative roofing systems that many competitors lack. With over 55 combined years of roofing experience among principals, Santex brings institutional knowledge of San Antonio’s building codes, climate challenges, and neighborhood-specific roofing demands that newer entrants simply cannot match.

Stephens Roofing & Remodeling was founded in January 1983 under president Edward Torrez and has accumulated one of the strongest credential portfolios of any multi-decade San Antonio contractor. Their simultaneous GAF Master Elite, Owens Corning, and CertainTeed certifications make them one of the few firms in the market capable of offering the best warranty programs from three major manufacturers. They are notable for holding an explicit City of San Antonio Home Improvement Contractor License (#IC2-916836) and carry MBE (Minority Business Enterprise) and SBE (Small Business Enterprise) certifications — meaningful qualifications for public and government-adjacent contracts. Their geographic footprint is notably broad: San Antonio, Austin, New Braunfels, Boerne, Kerrville, Fredericksburg, Comfort, Victoria, and Marble Falls, covering both urban and Hill Country markets. All work is guaranteed in writing.

Founded in 2004 by Genaro Montelongo Jr., Bison Roofing has grown from a San Antonio residential contractor into one of the most geographically expansive roofing firms in Texas, operating offices in San Antonio (1445 Austin Hwy and 24405 Wilderness Oak), the Rio Grande Valley, Austin, Houston, and Corpus Christi. This statewide reach reflects their significant capacity for storm restoration response — a critical capability in Texas, which leads the nation in hail-damage insurance claims. Bison is one of only a small number of San Antonio-based firms to hold Owens Corning Platinum Preferred status, the manufacturer’s highest contractor tier, enabling them to offer the Owens Corning Platinum Protection Limited Lifetime Warranty. Their commercial and multi-family expertise sets them apart from purely residential competitors; their team handles apartment complexes, commercial buildings, and multi-unit projects alongside standard residential work.

Transcendent Roofing, operating as San Antonio Roofing Companies (sanantonioroofingcompanies.com), has achieved a rare tri-manufacturer certification combination in less than a decade: GAF Master Elite, Owens Corning certified contractor, and CertainTeed ShingleMaster — a combination that allows them to offer the best warranty programs from three leading manufacturers simultaneously. Their BBB accreditation was established just nine months after founding, reflecting rapid establishment of professional standards. They hold RCAT licensure, carry $2 million general liability insurance per incident (double the RCAT minimum for commercial work), and offer extended manufacturer warranties of up to 50 years. Under managing member Brad Ridenhour, Transcendent has built a dedicated project manager system with final inspections after every job — a process discipline that distinguishes them from contractors who handoff to subcontractors without follow-through. They are a member of the NW San Antonio Chamber of Commerce.

Roofer Chicks, founded in 2016 by Ami Feller in New Braunfels, is a women-owned roofing contractor with a multi-manufacturer certification portfolio that rivals firms with decades more history. Owner Ami Feller brings roofing experience dating to 1992 through family industry involvement, and she sits on the San Antonio chapter of the National Association of Women Business Owners (NAWBO). As a GAF Master Elite contractor, a Malarkey Emerald Premium Pro (Malarkey’s highest contractor tier), an Owens Corning certified contractor, a Tile Roofing Industry (TRI) certified installer, and a current RCAT member, Roofer Chicks has demonstrated a commitment to professional credentialing across multiple industry bodies simultaneously. Their BBB accreditation was obtained in the same year they were founded — a strong signal of immediate accountability. They maintain a San Antonio location at 1999 Gulfmart St and serve the broader New Braunfels-San Antonio-San Marcos corridor with a specialty in both residential replacements and complex low-slope commercial systems.

Rhino Roofers is among San Antonio’s fastest-growing roofing companies since its founding in April 2021. Under managing partner Dante Cantu, the company obtained BBB A+ accreditation on the exact date of their founding — an unusually rapid commitment to formal accountability. Their 2024 Owens Corning MVP Top Performer Award is a nationally competitive recognition granted to Platinum Preferred Contractors who demonstrate exceptional volume and quality during the award year. Rhino is also a 2024 DECRA Project of the Year Award winner for stone-coated metal roofing — a specialty particularly relevant to San Antonio homeowners seeking Class 4 impact-resistant systems with superior hail protection. Their RCAT Residential Roofing License #01-0639 is publicly verifiable, and they maintain active membership in both RCAT and the Central Texas Roofing Contractors Association (CTRCA). HAAG-certified inspectors on staff ensure professional insurance documentation. The 2025 San Antonio Express-News and San Antonio Current Readers’ Choice Award for Roofing adds further community recognition. They also serve Austin from a Round Rock office.
