Trusted Specialty Roofing for San Antonio Homeowners
San Antonio Specialty Roofing covers the systems that standard shingles cannot: flat commercial membranes, solar-ready decking, built-up gravel roofs, and green living installations that handle our South Texas heat and sudden hailstorms. Most specialty roofing projects in San Antonio run $4,500 to $18,000 depending on material and square footage, and Ridgeline Roofing Co. typically inspects within 24 hours and completes work in one to three days. Call (833) 756-5022 and a live person will answer, any hour, to schedule your free estimate.
We have been climbing San Antonio roofs since 2016. That is over 42 years of learning how a modified bitumen membrane holds up to a July afternoon on a flat roof near Lackland Air Force Base, or why a TPO system in Alamo Heights needs proper seam welding to survive our spring hail season. Cecil Hargrove founded this company on the belief that a roof is only as good as the crew who installs it and the promise that backs it. Our 90-Day Done Right Promise means exactly what it says: if it is not right, we come back and make it right. No forms to file, no arguments, no runaround. Our technicians are background-checked, uniformed, and trained in-house, not hired off a street corner after a storm rolls through. Every inspection is photo-documented from your actual roof, not a sales pitch in your driveway.
What Our Specialty Roofing Service Includes
Solar Ready Roofing
Solar ready roofing prepares your roof structure and decking to accept photovoltaic panels without the retrofit headaches that cost San Antonio homeowners thousands later. We reinforce rafters, install compatible underlayment, and seal penetration points before panels ever arrive, because adding forty pounds per panel to a standard deck in Terrell Hills or Leon Valley without preparation invites sagging, leaks, and voided panel warranties. Ridgeline Roofing Co. of San Antonio specifies GAF and Owens Corning solar-compatible systems, and we coordinate directly with your solar installer so the handoff is clean.
TPO Roofing
TPO, or thermoplastic polyolefin, is a single-ply white membrane that reflects San Antonio’s brutal summer sun and cuts cooling costs on flat or low-slope commercial and residential buildings. The material itself is only half the story; proper installation demands heat-welded seams and precise flashing at HVAC curbs and parapet walls, which is where cheap crews cut corners and where leaks start two seasons later. We install TPO from GAF and CertainTeed with full manufacturer warranty registration, and we have tracked enough TPO roofs through our hail-prone springs to know which seam details hold and which fail.
EPDM Roofing
EPDM is a synthetic rubber membrane, black or white, that has been the workhorse of Kirby Specialty Roofing and commercial zones from Kirby to Converse for decades. It flexes with temperature swings, resists UV breakdown, and repairs cleanly when a branch punches through during a Windcrest windstorm. Ridgeline Roofing Co. of San Antonio installs both fully adhered and mechanically attached EPDM systems, and we keep adhesive and seam tape in stock for same-day patch work when a leak cannot wait.
Modified Bitumen
Modified bitumen is an asphalt-based membrane, reinforced with polyester or fiberglass, that we torch-apply or cold-adhere to flat and low-slope roofs throughout San Antonio’s older commercial corridors and some mid-century residential neighborhoods. It handles foot traffic better than single-ply membranes, which matters for roofs with frequent HVAC access near Live Oak or Universal City. Our crews are certified for torch-applied installation, and we inspect every seam with electronic leak detection before we sign off.
Green Roof
Green roofing installs a living plant layer over a waterproof membrane and root barrier, turning a flat roof into insulation, stormwater management, and something genuinely pleasant to look at from a downtown San Antonio high-rise or a modern home in Selma. The system demands precise drainage, soil depth calibrated to plant selection, and a membrane that roots cannot penetrate. We have built green roofs with Boral and Owens Corning components, and we specify native Texas sedums and grasses that survive our drought cycles without constant irrigation.
Built-Up Roofing
Built-up roofing, or BUR, is the traditional gravel-surfaced, multi-ply asphalt system you see on older commercial buildings from Helotes to the industrial edges of San Antonio. It is heavy, it is proven, and when properly maintained it outlasts many newer systems. We install new BUR where code and structure allow, and we perform targeted restoration - replacing flood coats, re-graveling bare spots, sealing pitch pans around conduits - to extend service life without the cost of full tear-off.

Brands We Service for Specialty Roofing
We are an authorized installer for seven manufacturer lines, and we do not substitute materials without your written approval. On GAF systems, we have completed hundreds of TPO and modified bitumen installations across Bexar County, and we maintain current certification for their commercial warranty programs. CertainTeed’s Flintlastic membranes are our go-to for modified bitumen jobs in historic San Antonio districts where torch application is restricted, and we stock their SA-modified self-adhering base sheets for faster, safer installs. Owens Corning supplies our solar-ready decking and select green roof components, with full integration into their Total Protection Roofing System.
We also install IKO, Atlas, Tamko, and Boral products where the job calls for them. Boral’s concrete and clay tiles pair with our specialty underlayment systems on pitched sections of mixed-slope commercial buildings, particularly in Alamo Heights and Terrell Hills where architectural review boards have material requirements. Whether you have GAF, CertainTeed, Owens Corning, or any other make specified by your architect or property manager, we can source, install, and warranty it properly. No chasing down your own materials, no wondering if the crew has worked with the product before.
Signs You Need Specialty Roofing Right Now
- Pooling water that sits more than 48 hours after rain. Flat and low-slope roofs depend on positive drainage. A pond in the center of a TPO or EPDM membrane in San Antonio’s heat accelerates UV breakdown and invites algae that eats at seams. We measure slope and check drains during every inspection, and we can add tapered insulation crickets to redirect water without full replacement.
- Interior stains that appear after wind-driven rain, then dry and return. This pattern usually means a membrane seam or flashing detail has failed, not the field of the roof. On modified bitumen or built-up systems near Kirby or Windcrest, we see this where gravel has washed away and exposed the asphalt ply to cracking. Our photo inspection pinpoints the exact entry point.
- Bubbles or blisters in the membrane surface. Trapped moisture or air beneath TPO, EPDM, or modified bitumen expands in San Antonio’s 100-degree afternoons and contracts overnight, working the blister larger until it splits. Small blisters can be cut, dried, and patched. Widespread blistering usually signals installation error or end-of-life, and we will show you the difference.
- Granule or gravel accumulation in gutters and downspouts. Built-up roofs shed gravel as the flood coat ages; modified bitumen loses mineral surfacing. Once the protective layer is gone, UV attacks the asphalt directly. In Leon Valley and Lackland Air Force Base, we schedule annual surfacing inspections for commercial clients to catch this before it becomes a full recover job.
- Sagging deck or soft spots when walked. Specialty roofing membranes are waterproof, not structural. Soft spots mean moisture has saturated the insulation or decking beneath, often from a slow leak that pooled unseen. This is common in green roofs where drainage has clogged, or in older built-up systems in Converse and Live Oak. We probe with moisture meters and specify structural repair before any membrane work proceeds.
Our Specialty Roofing Process - Step by Step
- 1
Live intake and scheduling. When you call (833) 756-5022, a person answers. Not a queue, not a callback promise. We schedule your inspection for a specific two-hour window, and we call if traffic on Loop 410 or I-10 shifts that window. We will be there when we say.
- 2
Photo-documented roof inspection. Our uniformed technician walks your roof with a high-resolution camera, documenting membrane condition, seam integrity, drainage paths, and penetration flashing. You receive these photos with your estimate, not a generic stock image. In San Antonio’s specialty roofing market, we have seen too many estimates written from the ground.
- 3
Written estimate with upfront pricing. The number on the estimate is the number on the invoice. We itemize materials by manufacturer and specification, labor by task, and any structural or decking repair separately so you see where every dollar goes. For commercial clients in Universal City or Selma, we can phase work to accommodate tenant schedules.
- 4
Manufacturer-authorized installation. Our crews install to manufacturer specifications, not shortcuts. TPO seams are robot-welded or hand-welded with temperature-verified equipment. Modified bitumen torches are monitored with infrared thermometers. Green roof media is weighed and depth-checked. We register your warranty directly with GAF, CertainTeed, Owens Corning, or the appropriate manufacturer.
- 5
Completion walkthrough and 90-Day Done Right Promise. You walk the job with our lead technician. We address any concern on the spot. Then our written 90-Day Done Right Promise takes effect: if anything is not right, we come back and make it right. No paperwork to file, no arguing, no runaround. Cecil Hargrove put his name on this promise in 1984, and we still honor it the same way.
How Much Does Specialty Roofing Cost in San Antonio?
Specialty roofing in San Antonio spans a wide price range because the category covers everything from a small EPDM patch to a full green roof installation. A typical TPO or EPDM membrane replacement on a 2,000-square-foot flat residential or small commercial roof in San Antonio runs $8,500 to $14,000, including tear-off, insulation replacement if needed, and new membrane with manufacturer warranty. Modified bitumen systems run slightly less, $6,500 to $11,000 for the same footprint, while built-up roofing on larger commercial structures can reach $18,000 or more depending on gravel weight and access difficulty. Solar-ready roofing adds $1,200 to $3,500 to a standard re-decking job, and green roofs start around $15 per square foot for extensive systems with shallow media, climbing to $25 or more for intensive plantings with deeper soil and irrigation.
Several factors move these numbers. Roof access matters: a flat roof behind a Helotes ranch house is simpler than a downtown San Antonio commercial deck with crane restrictions and street closures. Structural repairs to saturated decking add $400 to $900 per section. Insulation upgrades to meet current energy code can add $1,000 to $4,000 depending on R-value target. And the membrane thickness and warranty term you select - a 60-mil TPO with a 20-year NDL warranty versus a 45-mil with 15 years - shifts material cost significantly.
To avoid overpaying, get an estimate that specifies manufacturer, membrane thickness, insulation type, and warranty term in writing. Vague quotes that say “commercial grade” or “best materials” leave room for substitution. Our estimates name the exact product line, and we do not change it without your signature. Every estimate is free, and we honor our Free Second Opinion offer if you have a written estimate from another contractor and want us to review it.

Frequently Asked Questions - Specialty Roofing in San Antonio
Specialty roofing is the category of roof systems designed for flat, low-slope, or architecturally specific applications where standard asphalt shingles will not perform. It includes single-ply membranes like TPO and EPDM, multi-ply systems like modified bitumen and built-up roofing, solar-ready structural decking, and green living roofs. In San Antonio’s climate, specialty roofing must handle intense UV exposure, rapid temperature swings, and hail impact while providing positive drainage on slopes too shallow for shingles.
Most residential and small commercial specialty roofing projects in San Antonio are completed in one to three days. A straightforward TPO or EPDM replacement on a 2,000-square-foot roof takes two days: one for tear-off and prep, one for membrane installation and detail work. Larger commercial built-up roofs, green roofs with extensive planting, or jobs requiring structural decking repair may extend to a week. We specify the timeline in your written estimate, and we do not leave a roof open overnight without proper temporary waterproofing. Call (833) 756-5022 for a schedule that fits your property.
Specialty roofing in San Antonio typically ranges from $6,500 for a basic modified bitumen installation to $18,000 or more for large commercial built-up or green roof systems, with most residential flat membrane jobs falling between $8,500 and $14,000. Solar-ready preparation adds $1,200 to $3,500. The final price depends on membrane type, insulation needs, structural condition, and access difficulty.
