Commercial Roofing
Single-ply, modified bitumen, and metal roof systems engineered for performance and code compliance
Commercial roofing is a different discipline than residential work. Roof decks are larger, penetrations are more numerous, mechanical loads are higher, and commercial roof systems only perform when installed by experienced crews to exacting detail. National Restoration is a commercial-first roofing contractor that installs, restores, and maintains flat and low-slope roof systems across office buildings, retail centers, warehouses, industrial plants, and mixed-use developments.
From rooftop deck assessments and core sampling to full tear-off and re-roof engineered for long-life service, we deliver turnkey commercial roofing that keeps buildings dry, keeps carriers satisfied, and keeps operations running. Our project managers understand occupied-building logistics: staged tear-off, crane and material staging plans, hot-work permits, fire watch, and rooftop safety programs.
Why Building Owners Choose Us
Six reasons property owners, facility managers, and general contractors keep us on speed dial.
Long-standing installer relationships with Carlisle, GAF, Firestone, Johns Manville, and Versico, installed to exact specification on qualifying systems.
Core cuts to determine deck type and insulation moisture, infrared scans for wet substrate, drone-based orthomosaic mapping, and a written report with life expectancy and budget options.
OSHA 10/30 crews, site-specific fall protection, hot-work permitting, fire watch, and daily tailgate safety briefings. Low EMR and clean OSHA record make us welcome on sensitive sites.
Phased tear-off to limit exposure, interior protection below the work zone, and coordination with tenant schedules. We can work nights and weekends when operations demand.
ENERGY STAR and CRRC-rated membranes, tapered insulation to code R-values, and reflective coatings that lower cooling loads and qualify for local energy rebates.
Preventive maintenance contracts with semi-annual inspections, drain clearing, flashing repair, and roof condition reporting to extend roof life and reduce surprise repairs.
Commercial Roof Systems We Install
The right system depends on building use, slope, insulation requirements, and budget. We help owners choose the system that performs for decades.
The dominant single-ply membrane in North American commercial roofing. Heat-welded seams, excellent chemical and UV resistance, and a bright white surface that reflects solar load.
- Welded seams deliver monolithic watertight surface
- ENERGY STAR reflective white or tan finish
- Mechanically attached, adhered, or ballasted
A 50-year-proven synthetic rubber membrane. Excellent weathering, long service life, and forgiving installation detail. Still the right choice for many roof decks.
- Exceptional hail and impact resistance
- Field seams using factory-applied tape technology
- Black or reflective white options
The premium single-ply choice for restaurants, manufacturing, and chemical-exposure environments. Superior resistance to grease, oils, and aggressive rooftop exhaust.
- Fire-resistant and chemical-resistant formulation
- Strong hot-air welded seams
- Multiple color options including cool-roof whites
Asphalt-based multi-ply systems with a long track record in North America. Self-adhered, torched, or hot-asphalt options depending on site conditions and fire restrictions.
- Multi-ply redundancy for critical facilities
- Granulated cap sheet for UV protection
- Excellent for high-traffic roof decks
Concealed-fastener metal roof systems for architectural, industrial, and long-span applications. 24 and 22 gauge Galvalume and aluminum with Kynar finishes.
- Long service life with proper maintenance — among the longest of any commercial system
- On-site panel fabrication for continuous runs
- Solar-ready snap-on attachment systems
Silicone, acrylic, and urethane coating systems that extend the life of existing roofs without full tear-off. A capex-friendly path to substantially extended service life.
- Tax-deductible repair expense on many projects
- Avoid landfill disposal of existing membrane
- Manufacturer-backed renewable warranties
Before Any Re-Roof, We Assess the Deck
Specifying a new membrane without understanding the deck underneath is how projects fail. We start every commercial re-roof with rigorous substrate evaluation.
Cores pulled across the roof to identify deck type (steel, concrete, wood, lightweight insulating concrete), existing insulation layers, and moisture content. Code implications and tear-off quantities become clear before bid.
Infrared scanning at dusk to identify heat-retaining wet insulation, followed by capacitance moisture readings. Owners see exactly what insulation needs to be removed versus reused.
Verification of current IECC insulation R-value requirements, wind uplift ratings (FM, UL), and structural capacity for tapered insulation and ballast systems.
Owners receive a detailed assessment report with photographs, core samples documented, and budget options ranging from targeted repair to coating restoration to full tear-off and replacement.
Distribution Centers & Manufacturing
Large-footprint industrial roofs bring unique challenges: hundreds of rooftop units, extensive piping, fall hazards at every skylight, and little room for operational shutdowns. We have installed and restored millions of square feet of single-ply and metal across distribution, cold storage, manufacturing, and logistics facilities.
Our logistics planning, rigging expertise, and material handling experience mean new roofs get installed on schedule even when trucks never stop rolling in and out of the dock doors below.

All Commercial Services Under One Contract
Roofing is rarely the only scope on a commercial property. We deliver the full envelope — roof, siding, windows, gutters, and storm-damage restoration — under one accountable contractor with a single project schedule.
TPO, EPDM, PVC, modified bitumen, BUR, and standing-seam metal systems for warehouses, retail, office, and industrial buildings.
Metal panel, EIFS, fiber cement, and masonry-veneer facade work for multi-tenant buildings, mixed-use developments, and industrial properties.
Storefront, curtain wall, and punched-opening commercial window replacement with thermally broken aluminum frames meeting IECC commercial energy codes.
High-capacity commercial gutter systems, internal scupper assemblies, downspout routing, and roof-drain coordination for low-slope commercial roofs.
24/7 emergency response, rapid envelope mitigation, full damage documentation, and insurance-claim support for commercial properties after severe weather.
Multi-building capital refresh, facade modernization, and common-area upgrades for business parks, mixed-use, and Class A repositioning projects.
