Full-service design, installation, and maintenance for every major commercial roof system
Commercial roofing is an entirely different discipline from residential work. The stakes are higher, the systems are more complex, and a failure means lost production, damaged inventory, or shuttered tenants. At National Restoration, we have built our commercial division around the engineering, expertise, and logistics required to deliver roofs that protect property portfolios for decades.
We install every major low-slope and steep-slope commercial system, from heat-welded TPO membranes and proven EPDM rubber to multi-ply modified bitumen, traditional gravel-surfaced BUR, and commercial-grade standing seam metal. Every project is designed around the building's occupancy, insulation strategy, wind zone, and owner's operating priorities. We handle new construction, re-roofs, tear-offs, restoration coatings, and full-service maintenance programs.
From a single standalone building to multi-property portfolios, we deliver the credentials, crews, and project management that commercial owners expect.
Long-running installation experience across the major commercial roofing systems — thermoplastic single-ply, EPDM rubber, modified bitumen, and built-up — installed to each manufacturer's published specification.
Because we install every major system, we specify around the building's real needs rather than defaulting to whatever a single-system contractor happens to sell. The right roof for your building is the one we recommend.
Every commercial roof is designed to meet the FM Global, UL, and ASCE 7 wind uplift and fire rating requirements for the occupancy and location. We provide engineered attachment drawings on request.
Code-compliant insulation values, cool-roof surfacing, and continuous air barriers are built into every specification. We document compliance with ASHRAE 90.1, IECC, and local code amendments.
We run multi-building programs for property owners, REITs, and facility managers. A single point of contact coordinates budget planning, tenant notices, phasing, and warranty tracking across the entire portfolio.
Occupied buildings require occupied-building work habits. We schedule low-odor cold-applied or self-adhered systems where needed, coordinate deliveries away from tenant traffic, and keep operations running during the re-roof.
Explore our full commercial lineup. Every system is backed by manufacturer specifications and a 5-year workmanship warranty (longer terms available with system upgrades). Material warranty varies by product tier selected at proposal.
The most specified commercial membrane in North America. White heat-reflective TPO reduces cooling costs, heat-welded seams deliver monolithic strength, and service life reaches 25+ years.
The most proven single-ply system in commercial roofing, in service since the 1960s. Black synthetic rubber with exceptional ozone, UV, and temperature-swing resistance.
Multi-ply SBS and APP membrane roofs with factory-manufactured sheets. Torch-down, cold-applied, or self-adhering installation delivers redundancy single-ply cannot match.
The traditional tar-and-gravel commercial roof. Multi-ply hot asphalt assembly with gravel ballast that has protected warehouses, schools, and institutional buildings for more than a century.
Architectural and structural standing seam panels for retail centers, agricultural facilities, and institutional buildings. 50+ year service life with unmatched wind and hail performance.
Fluid-applied silicone, acrylic, and urethane coating systems that meaningfully extend the service life of aging commercial roofs at a fraction of replacement cost, while improving reflectivity.
From first assessment to final warranty delivery, our process is designed around the priorities of facility managers, property owners, and general contractors.
We start with a full rooftop walk, drone survey where appropriate, and core samples to document the existing assembly, moisture content, and deck condition. You receive a detailed written report.
Multiple system options are engineered with lifecycle cost analysis, energy modeling, and warranty comparisons so you can make a decision grounded in real numbers, not sales pressure.
Our team coordinates with local code authorities as required, prepares manufacturer submittals, safety plans, and pre-construction meetings with tenants and stakeholders. Nothing starts on the roof until the paperwork is complete.
Daily tear-offs and dry-ins protect the building's interior at every phase. Experienced crews install the full assembly, including insulation, cover board, membrane, and flashings, to manufacturer spec.
On larger jobs we welcome the owner's third-party consultants and roof reviewers, which is the best independent quality check an owner can put in place.
You receive a complete close-out package with warranty certificates, as-built drawings, product documentation, maintenance recommendations, and a direct line for service calls.
Scheduled maintenance extends roof life, preserves total-system warranties, and catches small issues before they damage tenant spaces or production equipment. Our programs are tailored to each property portfolio.
Bi-Annual Inspections
Spring and fall walk-throughs with a detailed photo report documenting seams, flashings, drains, and equipment impacts for every building in the portfolio
Preventative Repairs
Minor repairs are completed on the same visit when possible, with larger work bundled and pre-approved through your facility management team
Budget & Capital Planning
We provide five-year capital plans with expected replacement timing, anticipated costs, and restoration-coating options that help building owners avoid surprise capex
From TPO and EPDM to modified bitumen, BUR, and metal, we install the full commercial lineup and back every project with engineering, expertise, and responsive service. Schedule your rooftop evaluation.
