Commercial Roofing

A commercial roof is not a one-time purchase. It is an asset with a service life, a maintenance budget, and a renewal date. The way it is installed, the way it is maintained, and the contractor who handles both have an outsized effect on total cost of ownership across a 25-year life.

A 60-mil TPO installed correctly with proper insulation and tapered drainage and serviced under a preventive maintenance program will outperform the same membrane installed by the lowest bidder, with no maintenance, by 8 to 12 years. A study from Firestone Building Products found that average commercial roof systems under preventive maintenance lasted past their 20-year warranty term. Systems without maintenance averaged 13 years before requiring replacement. The math is consistent across manufacturers and membranes.

We organize our services around how a commercial roof actually ages: install it correctly, maintain it deliberately, repair it when it makes sense, and replace it when the numbers say to. Every service on the menu below feeds into that lifecycle.

We work on every major commercial roof system used in the Charlotte market. For new installations and replacements, we install GAF commercial roofing systems and issue manufacturer NDL warranties through GAF. For existing roofs of other types, we provide repair, maintenance, and service work. Which approach is right for your building depends on the existing system, slope, deck type, insulation requirements, FM Global compliance if your property is FM-insured, energy code, and local climate exposure.

TPO (thermoplastic polyolefin). The dominant Charlotte commercial system over the past decade. White reflective membrane reduces summer cooling load, heat-welded seams create bonds as strong as the membrane itself, and 60-mil thicknesses are standard for new installations under NDL warranty. For new installations and replacements we install GAF EverGuard TPO with manufacturer NDL warranties of 15, 20, 25, or 30 years depending on membrane thickness and warranty class selected. We also service and repair existing TPO systems from other manufacturers.

EPDM (ethylene propylene diene monomer). A black or white synthetic rubber membrane that has been the workhorse of commercial roofing for 50 years. Long service life, broad temperature tolerance, and forgiving installation. EPDM is common on Charlotte buildings installed in the 1990s and 2000s. We service, repair, and maintain existing EPDM systems; for new installations and replacements we recommend GAF TPO or PVC under NDL warranty.

PVC (polyvinyl chloride). Chemical-resistant single-ply membrane used on restaurants with grease exhaust, chemical processing facilities, and roofs with persistent chemical or oil exposure. Heat-welded seams, similar installation methodology to TPO, with superior chemical resistance. For new installations we install GAF EverGuard PVC under manufacturer NDL warranty.

Modified bitumen. Multi-ply asphalt-based system, torch-applied or self-adhered, well-suited to high-traffic commercial roofs and buildings with rooftop equipment that punishes membranes. Granule-surfaced cap sheet provides UV protection and walkway durability. For new installations we install GAF Ruberoid systems under manufacturer NDL warranty.

Standing-seam and architectural metal. Mechanically seamed and snap-lock metal systems for steep-slope commercial, mixed-use, hospitality, and industrial buildings. 50-plus year service life when installed and maintained correctly.

Roof restoration and coatings. Acrylic, silicone, and polyurethane coating systems applied over existing membranes to extend service life by 8 to 15 years. We install GAF coating systems with manufacturer warranties on the coating itself. The right answer for some aging roofs; the wrong answer for others. We tell you which.

New construction roofing. Tilt-up warehouses, office buildings, retail pads, multifamily, light industrial. We coordinate with the GC, the architect, and the manufacturer's tech rep on the membrane spec, insulation R-value, drainage design, and FM Global compliance where required.

Roof replacement. Tear-off and full system replacement when the existing roof has reached end of service life. We document the existing assembly, recommend the appropriate replacement system based on building use and budget, and issue the manufacturer NDL warranty on completion.

Roof restoration and coatings. Coating-based service-life extension on existing membranes that are still structurally sound. Less disruptive and less expensive than replacement, with manufacturer warranties of 10, 15, or 20 years on the coating system itself. We recommend restoration only when the substrate justifies it.

Repair work. Targeted leak repairs, seam restoration, flashing rebuilds, and storm damage response. Detailed scope documentation and a written 5-year workmanship warranty on covered repairs. See our [commercial roof repair page] for the full methodology.

Preventive maintenance programs. Annual or semi-annual inspections, drain and scupper cleaning, minor seam and flashing maintenance, written condition reports with photo documentation. Maintenance contracts on multi-property portfolios use standardized reporting so your asset team can compare buildings year over year.

Comprehensive Roof Inspections and condition assessments. Pre-purchase inspections, capital planning assessments, end-of-warranty assessments, and post-storm damage documentation. Each inspection produces a written report with photos, findings, and recommended actions sequenced by urgency.

There is a difference between a contractor who can install a system and a contractor certified to issue the manufacturer's NDL warranty on it. We are GAF certified for commercial roofing systems, which means GAF audited our installation history, our crew training, and our QA processes before granting that certification. GAF NDL warranties are the only manufacturer-backed NDL warranties we issue, and we issue them on every qualifying GAF system we install at completion.

NDL means "no dollar limit." On a 20-year NDL warranty, the manufacturer is on the hook for any covered failure of the system, with no cap on repair cost. That is fundamentally different from a "20-year material warranty" that covers only the membrane sheet at prorated value. Both phrases get used loosely. We tell you which one applies to your roof, in writing, before you sign anything.

For FM Global insured properties, we install systems to FM 4470, FM 4474, and other applicable wind uplift and class ratings, and we provide the documentation your insurance carrier requires. If you do not know whether your property is FM-insured or what its rating requirements are, we will help you find out.

Property managers and asset managers running multi-building portfolios have a workflow that is different from a single-building owner. We are built to work inside that workflow.

Single project manager per account. Whether you manage one building or fifteen, you have one named project manager at our company who knows your portfolio, your reporting requirements, and your tenants. You are not routed through a service desk.

Standardized reporting across the portfolio. Inspection reports follow the same template across every building under contract, so your team can compare conditions year over year and across properties. Every report includes location, system type, age, current condition rating, and recommended actions sequenced by urgency.

Capital planning support. For portfolios where roof condition feeds into capital planning, we provide multi-year condition forecasts that estimate replacement timing and budget by building. Your finance team gets numbers they can defend in a budget meeting, not vague "needs replacement soon" notes.

Coordinated scheduling around tenant operations. Multi-tenant office, retail, medical office, and light industrial buildings each have different operational sensitivities. Scheduling, access, HVAC coordination, and tenant notifications are coordinated with you and adjusted per property.

Master service agreements for multi-property maintenance. Annual or semi-annual maintenance contracts with consolidated invoicing, single PO structure, and one renewal date for the whole portfolio.

Most commercial roof failures in the Charlotte market are not random. They follow predictable patterns driven by climate, system type, and how the roof was originally installed. These are the conditions we see most often when we walk a Charlotte commercial roof for the first time.

Failed seams on aging single-ply membranes. Heat-welded TPO and PVC seams typically fail at edges where the original weld was thin, where dirt or moisture was trapped during installation, or at parapet flashing transitions. Glued EPDM seams fail when the original adhesive reaches end of service life. Charlotte's combination of UV exposure, summer membrane surface temperatures of 160 to 180 degrees Fahrenheit, and freeze-thaw cycling accelerates seam failure across all single-ply systems.

Penetration and flashing failures. Penetrations are the single most common leak source on a commercial roof. Pipe boots crack at their bases. HVAC curb flashings pull away after years of thermal cycling. New penetrations from telecom installs, solar work, or other trades are often sealed with the wrong product or none at all. Pipe boots have a real-world service life of 8 to 12 years in the Charlotte climate; HVAC curb flashings tend to need attention by year 15.

Drainage and ponding water failures. Charlotte's afternoon thunderstorms produce rainfall intensities that overwhelm scuppers and internal drains designed for older, lower rates. Standing water that should clear in 12 hours sits for two days. Persistent ponding accelerates membrane breakdown, biological growth, and seam stress, particularly near drains and scuppers where debris accumulates.

Storm damage from hail and wind. Hail events two or three times a year leave puncture damage that often is not visible from the parapet. Wind uplift damage to edge metal and coping is common after named storms. Both are insurable but require documentation from someone who knows what to look for.

Wet insulation hidden under intact membrane. A small leak that has been active for six months or longer often produces wet insulation across an area much larger than the visible water stain inside. Wet ISO holds moisture against the deck, accelerates corrosion of fasteners and steel decking, and produces inspection reports that look fine until the membrane is cut and the assembly is exposed.

Coping joint and parapet sealant failures. Coping joint sealant in the Charlotte climate has a real-world service life of 8 to 12 years before it needs replacement. Failed splice plates, corroded fasteners, and pulled base flashings on parapets show up consistently on roofs at the back end of that window.

When we walk a Charlotte commercial roof, these are the failure modes we look for first. Diagnostic Roof Inspections include thermal imaging and moisture meter readings to find the problems your eye cannot, particularly wet insulation and active seam stress. Comprehensive Roof Inspections for capital planning purposes catalog conditions across the full assembly so your asset team knows what is coming.

Super Roofing Company is family owned and locally operated. We have been in and part of the Charlotte metro communities we serve for years. Our office at 8811 Charlotte Highway in Fort Mill, SC sits 20 minutes from Uptown Charlotte and is centrally positioned for the Charlotte commercial corridors we serve: SouthPark, Ballantyne, University Research Park, South End, Uptown, NoDa, Plaza Midwood, the Westinghouse Boulevard / I-77 industrial belt, and the I-485 outer ring including Concord, Huntersville, Matthews, and Pineville. We work York and Lancaster counties on the South Carolina side.

Family ownership in commercial roofing matters at year four, year seven, and year twelve, when a warranty inspection or manufacturer claim is needed. The same ownership that signs your warranty is the ownership that answers that call. That continuity is the difference between a warranty that is honored and a phone tree that goes nowhere.

Commercial roofing pricing is not a flat per-square-foot number. The variables that move the price include system type, insulation R-value required by code, deck type, edge metal complexity, drainage and tapered insulation requirements, building height and access, tenant occupancy during work, and FM Global rating requirements if applicable.

A reasonable framing for capital planning purposes: a TPO replacement on a typical Charlotte commercial roof falls in a range from the mid single digits to the low double digits per square foot, all-in. Coatings and restorations cost a fraction of replacement per square foot but extend service life rather than resetting it. Repairs are scoped per project and run from low four figures to mid five figures depending on access, material, and the amount of wet insulation found.

The lifecycle math is the conversation worth having. A correctly installed roof with a maintenance program will outlast a discount installation by years and cost less per year of service life. We will show you the numbers, not just the per-square-foot quote.

1. Initial conversation. A project manager (not a service desk) takes the call, gathers building details, discusses your situation, and schedules the appropriate next step: a Diagnostic Roof Inspection for a leak, a condition assessment for capital planning, or a project consultation for a planned replacement.
2. Onsite inspection or assessment. Roof access, full system walk, drainage and penetration review, photo documentation, and any specific testing the project warrants (thermal imaging, moisture meter readings, core cuts).
3. Written report and proposal. Findings documented in a written report. Proposal specifies system, manufacturer, warranty class, scope, schedule, crew size, and total cost. No verbal commitments, no scope changes after signature without a written change order.
4. Pre-job coordination. Property manager point of contact confirmed. Tenant notification coordinated where applicable. HVAC shutdowns, hot work permits, and fall protection plans completed before work begins.
5. Execution. Certified crews on site, daily progress communication to your point of contact, daily cleanup, and documentation of any unexpected conditions found.
6. Closeout. Photo documentation of completed work, signed work order, manufacturer NDL warranty registration filed, and our 5-year workmanship warranty issued in writing on company letterhead. Final walkthrough on the roof when you want one.
