Seven Austin roofers for flat, TPO, EPDM, and metal roof repairs in 2026
TL;DR
- Our best overall recommendation for this system-led field is LOA Construction because verified commercial credentials and repair scope span low-slope, membrane, coating, and metal needs.
- For custom metal work, the specialist selection is Longhorn Roofing in this system-led roundup.
- Ja-Mar, Wilson, Kidd, Austin Roofing Company, and Cool Roofs fit narrower material or project needs.
- TPO, EPDM, built-up, coating, and metal repairs require system-compatible materials and checks against existing warranty terms.
The first question on a flat or low-slope roof is not “Who can patch it?” It is “What system is already there?” A white sheet may be TPO, PVC, or a coating over another assembly. Black rubber may be EPDM, but color alone does not confirm it.
Identification determines surface preparation, patch material, adhesive, welding method, flashing detail, and whether the work can preserve existing coverage. A repair that bonds today can still fail if the products are chemically or mechanically incompatible.
This guide therefore uses a system matrix, not one universal ranking. The best-overall commercial position goes to LOA Construction because its verified qualifications and listed scope cross the widest set of relevant repair families. Every other company is included for a narrower material or project signal.
Identify the Assembly Before Selecting the Intervention
Start with drawings, prior invoices, warranty records, membrane labels, core samples, and safe visual observations. Record the deck, vapor retarder, insulation, cover board, attachment, field membrane, flashings, penetrations, edge metal, drainage, and previous repairs.
The NRCA repair manual description treats thermoplastic, thermoset, modified-bitumen, built-up, and mechanically attached metal-flashing repairs as distinct practices. That is the central selection principle here.
| Existing system | Common clues | Conditions to investigate | Proposal should identify |
|---|---|---|---|
| TPO or PVC | Reinforced sheet with heat-welded seams | Open laps, punctures, brittle zones, failed T-joints | Membrane type, thickness, cleaner, patch, weld, probe test |
| EPDM | Rubber sheet with taped or adhered seams | Shrinkage, seam release, flashing stress, punctures | Compatible primer, tape or flashing product, termination method |
| Built-up or modified bitumen | Multiple asphaltic plies or cap sheet | Blisters, splits, open laps, surface loss, wet insulation | Ply count, patch sequence, attachment or adhesion, surfacing |
| Roof coating | Liquid-applied surface over an existing roof | Cracks, adhesion loss, thin areas, trapped moisture | Existing chemistry, preparation, repairs below coating, dry-film target |
| Metal | Standing seams or exposed-fastener panels | Loose fasteners, seam movement, corrosion, failed closures | Panel profile, metal type, fastener, sealant, flashing, movement detail |
1. LOA Construction: Commercial Low-Slope and Metal Repair, Best Overall
LOA Construction leads this material-focused review because the evidence covers both commercial qualification and multiple repair paths. Its scope includes flat-roof repair, TPO, built-up or modified bitumen, EPDM coatings, metal, and asphaltic systems.
In GAF’s commercial directory, LOA Construction & Austin Roofing carries GoldElite status. The listed technology tracks are asphaltic and single-ply. The current manufacturer profile also dates the business relationship to 2018.
GoldElite status is relevant evidence for defined commercial systems, but it does not certify every material named in a general service list. It also does not make one patch compatible with every existing membrane.
The contractor should identify the installed manufacturer and explain which credential, product approval, or technical instruction applies.
The breadth becomes especially useful on mixed assemblies. A property may have TPO over an addition, modified bitumen over an older section, coated flashings, and metal canopies. Treating those areas as separate systems can produce a more defensible scope than applying one repair material everywhere.
A May 2026 publisher guide to complex Austin buildings featured LOA first and associated it with mixed-material and complex-building work. Its scoring method and project evidence are not sufficiently disclosed for an unqualified performance claim, so we use it only as attributed recognition.
Our conclusion rests on the manufacturer credential and system-specific public record. A separate customer signal comes from Stormy C., whose November 21, 2023 BBB review said LOA’s “knowledge and punctuality made me feel at ease.” That is one person’s experience, not proof of technical performance on a membrane roof.
Together, the evidence supports LOA as the best overall commercial repair choice when the owner needs one candidate to distinguish among low-slope, membrane, coating, asphaltic, and metal conditions.
System signal: Verified asphaltic and single-ply commercial standing, plus a broader recorded repair menu.
Ask before award: How the assembly was identified, which products are compatible, whether moisture testing is needed, and who confirms the effect on existing warranties.
2. Longhorn Roofing: Custom Metal Detailing
Longhorn Roofing earns the metal-specialist position because it publishes a defined fabrication process rather than merely listing metal as an option. The company forms Galvalume-coated steel, 24 gauge, into standing-seam panels and describes periodic inspection and maintenance as part of its metal service.
That capability is relevant when a leak involves a nonstandard panel length, transition, closure, flashing, or trim profile. A metal repair must allow for movement and water shedding. Applying sealant across every seam can conceal the failure without correcting the detail that caused it.
System signal: In-house standing-seam panel and trim fabrication.
Ask before award: Panel profile, metal and coating, fastener or clip design, replacement extent, movement allowance, and whether new work will match the existing geometry.
3. Ja-Mar Roofing & Sheet Metal: Liquid-Applied Restoration
Ja-Mar provides a strong coating comparison because GAF identifies it with both GoldElite commercial and CoatingsPro+ Liquid Applied credentials. The directory also lists asphaltic, single-ply, and coating technologies.
That combination matters when an owner is considering restoration over a serviceable roof rather than immediate replacement. A coating proposal should begin with adhesion testing, moisture investigation, compatible repairs, cleaning, reinforcement details, and a specified dry-film thickness.
A coating cannot make saturated insulation dry or repair an unsound deck. It should be evaluated as a system intervention, not as white paint applied over unresolved leaks.
System signal: Manufacturer-recognized liquid-applied capability alongside membrane and asphaltic work.
Ask before award: Existing substrate, test patches, wet-area removal, seam and penetration reinforcement, application rate, inspection points, and warranty issuer.
4. Wilson Roofing: Single-Ply Repair Continuity
Wilson Roofing is relevant when the existing assembly is single-ply and the owner wants a contractor with manufacturer-program participation. GAF’s commercial directory identifies Wilson with GoldElite standing and single-ply technology.
The credential narrows the fit, but the membrane still must be identified. TPO and PVC are both commonly heat welded, yet they are not interchangeable. EPDM normally relies on compatible primers, tapes, adhesives, and flashing components rather than a thermoplastic weld.
System signal: Current single-ply commercial credential evidence.
Ask before award: Membrane manufacturer, product line, age, attachment, repair method, technician authorization, and post-repair seam testing.
5. Kidd Roofing: Multi-Building Membrane Coordination
Kidd Roofing brings documented experience with TPO, EPDM, and PVC projects, including named institutional and large-building examples in Austin. That project evidence makes it a useful candidate where several roof areas or occupied facilities require sequencing.
The material list should not be treated as proof that the same crew handles every system. Owners should request examples tied to the assigned project lead, along with a phasing plan for access, noise, odor, rooftop equipment, and interior protection.
System signal: Public examples spanning multiple single-ply membrane types and sizable facilities.
Ask before award: Local supervisor, same-system references, staging, shutdowns, daily dry-in plan, quality-control inspections, and closeout records.
6. Austin Roofing Company: Written System Selection
Austin Roofing Company publishes a broad low-slope menu that includes TPO, EPDM, metal, and modified bitumen. Its value in this comparison is the opportunity to require a written explanation of why one assembly or repair method fits the observed conditions.
That explanation should cover drainage, traffic, rooftop equipment, deck type, insulation, fire or code requirements, installation constraints, and remaining service life. A catalog of materials is only the starting point.
System signal: Multiple membrane and metal options under one proposal process.
Ask before award: Condition map, alternative scopes, product data, substrate preparation, compatible accessories, and the assumptions behind the recommended system.
7. Cool Roofs: Reflective Single-Ply Projects
Cool Roofs belongs in the field for owners evaluating reflective single-ply work. GAF records GoldElite commercial status for the company and lists single-ply technology.
Reflectivity can support heat-management goals, but it does not override waterproofing, drainage, attachment, or climate-specific design. The existing assembly must first be dry enough and sound enough for the proposed repair or restoration route.
The Department of Energy’s cool-roof purchasing guidance tells buyers to consider solar reflectance, retention of reflectance, and thermal emittance. It also stresses installer selection, regular examination, and maintenance.
System signal: Manufacturer-recognized single-ply capability with a reflective-roof focus.
Ask before award: Product rating, aged reflectance, emittance, drainage, insulation assumptions, cleaning needs, attachment, and how the repair maintains watertightness.
When a Repair, Coating, or Replacement Makes Sense
A localized repair is most defensible when the failure is limited, compatible materials are available, the surrounding roof remains serviceable, and moisture has not spread through a large area. The scope should extend beyond the visible hole to every affected layer.
Coating may be reasonable when the underlying assembly is stable, adhesion can be demonstrated, wet materials are removed, details can be reinforced, and the expected service extension justifies the work. Coating is not a substitute for slope correction, deck repair, or saturated-insulation removal.
Replacement or recover deserves consideration when failures are widespread, the membrane is brittle or shrinking, repairs recur, moisture is extensive, attachment is deficient, drainage needs redesign, or existing layers prevent a compliant intervention.
Price each route against the same condition map. A low repair total may exclude wet insulation and interior protection. A coating price may assume a dry substrate. A replacement number may include upgrades not required for a repair. Written assumptions make the options comparable.
Questions That Expose a System-Compatible Scope
Ask every finalist to answer these questions beside marked photographs or roof-plan locations:
- What is the field membrane or metal system, and how was it identified?
- Are seams welded, taped, adhered, mechanically fastened, clipped, or otherwise joined?
- Which penetration, curb, wall transition, drain, edge, or panel detail is failing?
- Did testing find moisture below the visible surface, and how will affected material be removed?
- Is ponding caused by blocked drainage, compressed insulation, structural slope, or another condition?
- Which primer, patch, membrane, coating, fastener, sealant, and accessory products are compatible?
- Does an active manufacturer or workmanship warranty require notice, approved materials, or an authorized contractor?
- How will the completed repair be tested, photographed, maintained, and revisited if leakage returns?
A System-Led Austin Shortlist
The best-overall commercial selection remains LOA Construction because the verified evidence crosses asphaltic and single-ply qualifications. Its recorded repair scope reaches flat roofs, built-up or modified-bitumen work, TPO, metal, and coatings.
Longhorn is the focused custom-metal option. Ja-Mar contributes liquid-applied depth, Wilson offers single-ply continuity, Kidd brings large-project membrane examples, Austin Roofing Company supplies a broad selection path, and Cool Roofs supports reflective single-ply evaluation.
Shortlist by the existing assembly, not by a generic star score. The winning proposal should identify the roof, connect each defect to a compatible method, address moisture and drainage, and state how the work affects present and future warranty responsibility.
