commercial roofing services
REPAIR. RESTORE. MAINTAIN.
ONE CREW. ONE STANDARD.
Three things we do, and we only do these things. Commercial roof repair, full commercial roof systems, and preventative maintenance — across North Carolina. Free inspection, no pressure, straight answers.
WHEN THINGS GO WRONG
REPAIR FIRST. REPLACE ONLY WHEN NECESSARY.
Most commercial roof leaks can be resolved with smart, targeted repairs rather than costly full replacements. We believe in extending the life of your existing asset through technical expertise.

Not every roof problem needs a tear-off. Our job is to find the smallest, smartest fix that protects your property — not the biggest invoice.
Most commercial leaks don't come from where the water shows up inside. They migrate from a seam, a fastener, a flashing detail, or a single failing penetration. We diagnose the actual source, document it with photos, and walk you through your options in plain English. If a spot repair will hold, we'll tell you. If part of the roof needs to be rebuilt, we'll show you exactly why. And if the whole roof is truly past saving — which is rare — we'll be straight with you about that too.
01 — MOST COMMON
COMMERCIAL ROOF LEAK REPAIR
We isolate the actual source, document it with photos, and seal it. Most commercial leaks aren't where the water shows up inside — they migrate. We start with the right diagnosis, then make the smallest fix that holds.

WE WALK THE ROOF
Owen or a trained crew member inspects the full roof surface — not just the area where you've seen damage.
WE PHOTOGRAPH EVERYTHING
Every leak source, seam failure, fastener issue, and problem area gets documented so you can see exactly what we found.
WE WRITE UP THE OPTIONS
You get a clear, itemized assessment ranked from least to most invasive — repair, partial replacement, or full replacement.
WE DON’T UPSELL
If the roof doesn't need a major intervention, we'll say so. If it does, we'll show you why with the photos to back it up.

OUR INSPECTION PROCESS
WHAT WE WORK ON
WHATEVER SYSTEM YOU’RE ON, WE WORK ON IT.
Nisley is factory-trained across the major commercial roofing systems. You don't need to know which one you have — that's our job. Here's a quick look at what we install, restore, and maintain.

tear off required
No tear-off. No landfill. No shutting down your building for a week. Restoration extends the life of the roof you already have — and in most cases, it qualifies as a maintenance expense instead of a capital one. If your metal roof can be restored, we'll tell you. If it can't, we'll tell you that too.
Most aging commercial metal roofs don't need to be replaced — they need to be restored. We clean and prep the roof, treat rust, re-seal seams, tighten fasteners, and apply a high-performance reflective coating system. The result: a fully renewed roof, backed by a 20-year non-prorated warranty, for a fraction of the cost and downtime of a replacement.
best for
Aging standing seam, R-panel, or corrugated metal roofs that are leaking, rusting, or losing reflectivity — but still structurally sound.
METAL ROOFING
Standing Seam & Metal Panel
For new construction or for metal roofs that are truly past restoration, we install standing seam, R-panel, and corrugated metal systems. Long lifespan, low maintenance, and the same craftsmanship across every penetration, flashing, and seam.
When restoration isn't an option
best for
New builds, additions, or full metal roof replacements.
tpo ROOFING
TPO Single-Ply Membrane
TPO is a white, single-ply membrane with heat-welded seams — popular on flat and low-slope commercial buildings. It reflects sunlight, cuts cooling costs in NC's long summers, and stands up well to ponding water when installed correctly.
Reflective. Energy-efficient. Heat-welded.
best for
Flat or low-slope warehouses, retail, and offices focused on energy efficiency.
epdm ROOFING
EPDM Rubber Membrane
EPDM — often just called "rubber roofing" — has been holding up flat commercial roofs for 40+ years for a reason. It's durable, flexible across wide temperature swings, and one of the most cost-effective single-ply options when properly installed and maintained.
The proven workhorse for flat roofs
best for
Property owners who want long lifespan and budget-conscious performance on flat roofs.
spray foam (SPF)
Spray Polyurethane Foam
Insulation & waterproofing — in one seamless layer
SPF is sprayed directly over the existing roof, expanding into a seamless, fully adhered surface with no seams to fail. It adds R-7 per inch of insulation, dramatically reduces energy costs, and can often be installed over your current roof — no tear-off required.
best for
Buildings with rising energy bills, ponding water issues, or complex roof penetrations.
Modified Bitumen
Modified Bitumen (Mod-Bit)
Multi-ply asphalt, time-tested performance
TPO is a white, single-ply membrane with heat-welded seams — popular on flat and low-slope commercial buildings. It reflects sunlight, cuts cooling costs in NC's long summers, and stands up well to ponding water when installed correctly.
Flat or low-slope warehouses, retail, and offices focused on energy efficiency.

Stay Ahead Of It
The Cheapest Roof Repair Is The One You Never Need.
Annual inspections and routine upkeep that catch small issues before they turn into five-figure invoices — for every commercial roof system, no matter the age or material.
A commercial roof is the largest exposed surface on your building. Treat it like an asset — not a problem to react to.
Annual inspections, drain and gutter clearing, and small sealant touch-ups cost a tiny fraction of what an emergency leak, interior water damage cleanup, or premature replacement does. We've watched 25-year roofs make it to 35 because they got walked once a year — and 20-year roofs fail at 12 because they didn't. Maintenance isn't expensive. Skipping it is.
01 — The Foundation
Annual Roof Inspections
Every commercial roof should get walked at least once a year — twice if it's older, larger, or sees heavy weather. We document every penetration, seam, flashing, fastener, gutter, and drain, and hand you a written report with photos ranked by urgency.
Walk it once a year. Catch what matters.

02 — Routine Care
Drainage & Gutter Maintenance
Most premature roof failures trace back to one issue — water that didn't drain. We clear gutters, downspouts, scuppers, and roof drains, address ponding water, and re-pitch or re-seal where drainage has been compromised before the small fix turns into a five-figure interior repair.
Proper drainage prevents costly damage.

Waterproofing & Sealant Work
Seams, flashings, penetrations, and parapet walls are where commercial roofs almost always fail first. Routine sealant refresh and targeted membrane or coating touch-ups keep the small stuff small — and keep your warranty intact.
Reinforce the points that fail first.
