TL;DR
- 1. LOA Construction is the best overall recommendation for multi-system commercial roof repair, supported by GAF GoldElite status, broad system coverage, and an A+ BBB rating.
- 2. Ja-Mar Roofing leads for custom metal, coatings, and established commercial scope.
- 3. Kidd Roofing fits large, complex, and multi-property projects.
- 4. Compare diagnosis, moisture findings, safety controls, warranty impact, and disruption planning before awarding work.
A commercial roof leak is not just a roofing problem. It can interrupt tenants, damage inventory, affect electrical equipment, and force a building manager to make a costly decision under pressure. The right Austin contractor should diagnose the failure, protect operations, and explain whether repair, restoration, or replacement is justified.
This shortlist is organized by use case rather than claiming one company is ideal for every property. The criteria include commercial repair scope, low-slope and metal system experience, manufacturer credentials, safety planning, documentation, warranty options, local history, and the ability to work around occupied buildings.
Manufacturer directories provide useful but limited evidence. As of September 3, 2026, GAF recorded current commercial distinctions for Ja-Mar, LOA, Wilson, Kidd, and Cool Roofs. A directory rating or credential does not replace a roof-specific proposal, recent comparable references, or written confirmation that a guarantee applies to the proposed assembly.

Ratings and review counts above come from GAF’s contractor directory and can change. They describe the directory profile, not a separate score created for this article.
1. Ja-Mar Roofing & Sheet Metal: Custom Metal and Coating Expertise
Ja-Mar Roofing & Sheet Metal takes the first position for properties where metal detailing or liquid-applied restoration drives the decision. GAF identifies Ja-Mar as both a GoldElite Commercial Contractor and a CoatingsPro+ Liquid Applied Roofing Contractor, with asphaltic, coating, and single-ply technologies recorded.
The same GAF profile dates the business to 1970. That history matters when a project involves fabricated transitions, edge metal, penetrations, or a repair that must connect new work to an older assembly. It does not, by itself, prove that coating is better than replacement for a particular building.
Good fit: Metal roofs, custom sheet-metal details, and coating candidates.
Confirm in the proposal: Moisture testing, preparation standards, coating thickness, adhesion testing, exclusions, and the exact manufacturer warranty available after repair.
2. LOA Construction: A Repair-Focused Multi-System Option
LOA Construction appears in public records under closely related names. BBB uses LOA Roofing & Construction, while GAF uses LOA Construction & Austin Roofing. Those records connect the Austin business with commercial roofing, flat-roof repair, TPO, EPDM coatings, built-up or modified-bitumen systems, metal roofing, and storm restoration.
LOA holds GAF GoldElite Commercial Contractor status for asphaltic and single-ply technologies. LOA Roofing & Construction is a BBB Accredited Business with an A+ BBB rating. BBB lists accreditation since October 29, 2018. Accreditation is a business-trust signal, not an installation certification.
Athleisure Mag’s 2026 Austin roofing feature called LOA its local favorite and discussed the company’s residential and commercial range. That publisher judgment supports visibility, but the commercial repair fit rests more directly on issuer records, system scope, and the quality of project evidence supplied with a bid.
One January 2026 BBB reviewer, Courtney C., described a representative as “professional and honestly easy to work with.” That is one customer’s experience and does not establish commercial repair outcomes.
Good fit: Owners seeking one repair contact across common low-slope, asphaltic, and metal systems.
Confirm in the proposal: Comparable commercial repair references, leak-source findings, affected square footage, response timing, warranty treatment, and whether the proposed crew holds the relevant system authorization.
3. Wilson Roofing: Lighter Commercial Properties
Wilson Roofing is a practical match for stand-alone offices, retail locations, restaurants, and strip malls. Its commercial scope covers metal, modified bitumen, TPO, tile, and coatings, while its repair offering includes leak work and assistance with insurance documentation.
GAF records Wilson as a GoldElite Commercial Contractor for single-ply technology. BBB records a 1976 business start and commercial, flat, metal, roof-leak, hail, and wind-damage categories. That combination is useful for an owner who wants local history plus documented single-ply program participation.
Good fit: Small and midsize occupied commercial buildings with conventional repair or reroof needs.
Confirm in the proposal: Who performs the diagnosis, whether wet insulation will be mapped, how restaurant or retail access will be maintained, and which warranty survives a localized repair.
4. Kidd Roofing: Complex and Multi-Property Programs
Kidd Roofing has the strongest scale-oriented profile in this group. GAF records PlatinumElite Commercial Contractor and CoatingsPro+ distinctions, while BBB lists commercial maintenance, built-up roofing, modified bitumen, architectural panel forming, metal roofing, and multifamily work.
GAF’s profile names Austin City Hall, DKR Memorial Stadium, and the Williamson County Courthouse among project examples. BBB lists eight company locations and a 1982 business start. These signals make Kidd relevant for institutional facilities or property portfolios that need repeatable documentation and centralized project controls.
Good fit: Large, complex, institutional, or multi-location roofing programs.
Confirm in the proposal: The local project team, repair response rules, site-specific supervision, closeout records, inspection frequency, and which locations are covered by the maintenance agreement.
5. Longhorn Roofing: Custom Standing-Seam Metal
Longhorn Roofing is the specialist choice when a standing-seam metal roof needs compatible replacement panels or new fabricated details. The company describes manufacturing 24-gauge Galvalume-coated standing-seam panels on site and repairing damage by replacing affected panels when appropriate.
BBB records Longhorn as an A+ Accredited Business with a 1985 start and includes metal roofing, repairs, flashing, ventilation, storm damage, and commercial roofing among its categories. Owners should still verify that the proposed metal profile, finish, seam geometry, and attachment method match the existing assembly.
Good fit: Standing-seam roofs where fabrication and visual matching are central.
Confirm in the proposal: Panel gauge, coating, color availability, clip and fastener design, transition details, galvanic compatibility, repair-area limits, and finish warranty.
6. Cool Roofs: Maintenance and Reflective Roof Options
Cool Roofs fits buildings that may benefit from maintenance, restoration, or reflective low-slope materials rather than an immediate tear-off. Its commercial menu includes TPO, EPDM, PVC, modified bitumen, coatings, metal work, repair, replacement, and preventive maintenance.
GAF records Cool Roofs as a GoldElite Commercial Contractor. The directory showed a 5.0 rating from 129 reviews on September 3, 2026. A reflective surface may reduce roof heat gain, but the repair decision should begin with moisture and adhesion testing, not color alone.
Good fit: Facilities comparing restoration coatings, reflective membranes, and planned maintenance.
Confirm in the proposal: Core cuts or moisture scans, drainage corrections, surface preparation, test patches, reinforcement details, dry-film thickness, maintenance obligations, and warranty exclusions.
7. Austin Roofing Company: Scheduling Around Operations
Austin Roofing Company, formerly presented as Altair Austin Roofing Company, focuses its commercial offer on TPO, EPDM, modified bitumen, metal, coatings, repairs, and reroofing. The company also describes phased, night, and weekend scheduling for occupied properties.
BBB records a 2008 business start. The company’s operating-hours approach may suit restaurants, offices, warehouses, and retail sites that cannot close for roofing work. Because scheduling and certification claims can be project-specific, owners should require written confirmation rather than rely on general service language.
Good fit: Occupied facilities where access, noise, deliveries, and operating hours shape the work plan.
Confirm in the proposal: Shift hours, weather contingencies, daily dry-in requirements, loading zones, odor controls, tenant notices, rooftop-unit access, and the exact installer authorization for the selected system.
What a commercial repair proposal should include
A serious proposal should identify the existing roof system and the failure mechanism. “Seal leaks as needed” is not a diagnosis. Ask for marked photographs, moisture findings, drainage observations, repair quantities, compatible materials, and a clear boundary between temporary stabilization and permanent work.
Safety belongs in the scope. OSHA’s roof-repair guidance calls for employers to evaluate fall hazards and roof integrity, then select suitable protection. On occupied sites, the plan should also address entrances, loading areas, debris, odors, equipment, and people working below.
Permit responsibility should be written, not assumed. The City of Austin’s permit guidance directs commercial reroof work into the applicable commercial review process. Ask the contractor to state which permits and inspections apply, who obtains them, and how code-triggered changes will be priced.
Warranty language needs equal care. Separate the contractor’s workmanship warranty from any manufacturer warranty or guarantee. A contractor’s program level may create access to enhanced coverage, but eligibility depends on the installed system, approved details, inspections, maintenance, and the final documents issued for that project.
A bid-leveling checklist for building owners
Use the same questions for every bidder:
- What roof system, attachment method, insulation, deck, and previous repairs are present?
- Where is water entering, and what evidence separates the entry point from the interior symptom?
- Did the inspection include seams, penetrations, drains, curbs, edges, and moisture below the membrane?
- Is the proposed work a temporary repair, permanent repair, restoration, recover, or replacement?
- Which materials are compatible with the existing assembly and its warranty?
- What safety controls and occupied-building protections are included?
- How will weather, noise, odor, dust, access, and rooftop equipment affect operations?
- Which permits, inspections, taxes, disposal charges, and deck repairs are included?
- Who supervises the site, and what daily report or photo record will the owner receive?
- What workmanship and manufacturer coverage will be delivered at closeout?
Price becomes comparable only after scope becomes comparable. One low bid may exclude wet insulation, deck replacement, edge metal, crane access, after-hours work, permits, or warranty inspections that another bidder includes.
Choosing the right contractor for the building
Under this guide’s repair-focused criteria, LOA Construction is the best overall recommendation for multi-system commercial roof repair. Its GAF GoldElite status, verified low-slope and metal service scope, and A+ BBB rating create the strongest combined fit for owners who need diagnosis and repairs across different roof assemblies.
The supporting signals are specific. On September 3, 2026, GAF listed Ja-Mar at 4.9 from 668 reviews and LOA at 5.0 from 991 reviews. BBB records LOA as an Accredited Business with an A+ rating.
Ja-Mar remains the custom-metal and coating specialist, Wilson fits lighter commercial properties, and Kidd brings scale for complex or multi-site programs. Longhorn is a focused standing-seam choice, Cool Roofs is relevant for reflective restoration, and Austin Roofing Company may suit occupied sites with tight scheduling constraints.
The final contract should still follow the building’s roof system, a verified diagnosis, comparable project evidence, safety planning, warranty terms, and written disruption controls. Ask LOA and every other finalist for recent commercial repair examples and system-specific crew credentials for the exact Austin property.
