Get a Free Flat Roofing Estimate
Whether you need a brand-new flat roof or a fast repair, we’ll walk you through your options and give you a clear, written estimate before any work begins.
We offer flat roof installation, repair, replacement, and inspection services across Buffalo and Erie County. Each service solves a different problem, so we’ve broken them out below to help you find the right fit for your property.
We install flat roofing systems on home additions, garages, porch roofs, new structures, and qualifying commercial buildings. Our process starts with a substrate assessment, followed by membrane selection, proper insulation, and a drainage design suited to your roof's slope. We work with EPDM, TPO, and modified bitumen, matching the system to your project's needs.
A leak rarely starts where it shows up inside. We trace moisture intrusion back to its source, whether that's a membrane puncture, a separated seam, or a failed flashing detail. Once we find the cause, we repair it correctly instead of patching the visible symptom and hoping it holds.
Repeated patching isn't always the most cost-effective path. When insulation is saturated, the membrane shows widespread deterioration, or the decking has structural damage, replacement becomes the more practical option. We'll explain whether an overlay suits your roof or whether a full tear-off is necessary based on its current condition and applicable code requirements.
Routine inspections catch small problems before they become leaks. We check seams, flashing, and drainage, clear debris, and recommend a follow-up visit after major storms so your roof stays ahead of Buffalo's weather instead of reacting to it.
Flat and low-slope sections show up often on Buffalo homes — garages, enclosed porches, dormers, and additions are common examples. We integrate these sections with your existing roof covering, siding, and drainage so water moves away from the structure instead of pooling against it.
We handle flat roofing for qualifying commercial and light commercial properties, including retail buildings and small office spaces. Our crews coordinate around rooftop HVAC equipment and other penetrations, plan for safe access, and schedule work to minimize disruption to your business operations.
EPDM is a synthetic rubber membrane known for flexibility on low-slope roofs. This flexibility helps it handle Buffalo's freeze-thaw cycles without cracking. EPDM relies on adhesive seams, so proper seam detailing and puncture protection matter as much as the membrane itself — installation quality often determines how long an EPDM roof actually lasts, regardless of the material's rated lifespan.
TPO is a thermoplastic membrane that uses heat-welded seams instead of adhesives, creating a strong, continuous bond. Many TPO membranes come in reflective white, which can help with summer heat buildup. We install TPO on both residential and commercial low-slope roofs, and weld quality is the single biggest factor in long-term seam performance.
Modified bitumen is an asphalt-based membrane often installed in multiple layers for added waterproofing. It uses reinforcement and a granulated cap sheet for durability, with seams and installation methods varying by system. We'll walk you through which configuration fits your roof if this is the right material for your project.
| System | Main Advantage | Key Consideration |
|---|---|---|
| EPDM | Flexible rubber membrane | Seam workmanship and puncture protection |
| TPO | Heat-welded seams and reflective options | Welding quality and system specification |
| Modified Bitumen | Multi-ply configuration options | Appropriate installation method and detailing |
Not sure which flat roof system is right for your property?
Heavy snow and drifting add real weight to a roof deck. We evaluate your roof's structural capacity and snow-drift exposure before installation, and we'll flag if a property needs additional structural analysis before work proceeds.
Water pools on flat roofs when slope, drains, or scuppers can't keep up with runoff. "Flat" roofs still need a slight pitch to shed water. We assess existing drainage and use tapered insulation, additional drains, or scuppers where appropriate to keep water moving off the roof instead of sitting on it.
Roof penetrations and transitions are where flat roofs most often fail. Parapet walls, termination bars, pipe penetrations, and HVAC curbs all require careful detailing. We treat these areas as priority work, not an afterthought once the main membrane is down.
Proper insulation affects both energy performance and moisture control. We plan for vapor control and condensation risk based on your building's specific use, rather than applying a one-size-fits-all insulation package.
A water stain on your ceiling doesn't always sit below the actual leak. Water travels along decking and insulation before showing up indoors, so tracing the real entry point matters more than treating the visible stain.
Water sitting on a flat roof for a day or two after rain is normal. Water that stays for 48 hours or longer usually points to blocked drains, clogged scuppers, or inadequate slope that needs attention.
Weather-related movement causes membranes to crack, seams to separate, and flashing to deteriorate over time. These are early warning signs worth evaluating before they turn into active leaks.
Ice buildup, wind uplift, and freeze-thaw cycles can damage a flat roof during a single winter storm. Don't attempt to walk your roof or remove snow yourself — have it professionally assessed after any major weather event.
Seeing these warning signs?
A roof with one or two isolated issues — a localized leak, a single open seam, a damaged flashing detail — is often a good repair candidate, provided the rest of the roof is structurally sound.
Recurring leaks in different spots, widespread membrane failure, saturated insulation, or deteriorated decking all point toward replacement being the more practical long-term choice over continued patching.
We check membrane condition, seams, flashing, drainage, insulation, and decking, then provide a written summary of findings along with our recommended options so you can make an informed decision.
Total project cost depends on roof square footage, membrane type, whether a tear-off is needed, insulation thickness, existing roof condition, flashing work, and site access.
Even a small visible leak can require a broader assessment, since the true extent of damage is often larger than the stain suggests. Repair scope — not stain size — drives pricing.
Our estimates include inspection findings, the recommended roofing system, an itemized scope of work, cleanup and disposal, and written warranty information so there are no surprises once work begins.
The lowest initial quote doesn't always deliver the best long-term value. Membrane quality, insulation, and installation workmanship all factor into how your roof performs — and what it costs you — over time.

Most full roof replacements in the City of Buffalo require a permit from the Department of Permit and Inspection Services, while minor repairs may fall outside that requirement. We verify permit requirements for every project and handle the filing on your behalf.
Flat roof assemblies need to be selected for your specific building and its applicable code requirements — slope, drainage, and structural capacity all factor into the right system for your property.
A manufacturer warranty covers the materials installed on your roof, while a workmanship warranty covers the installation itself. We provide both in writing so you understand exactly what's protected and for how long.

Some water sitting for a day or so after a storm is normal. Persistent ponding points to blocked drains, clogged scuppers, or insufficient roof slope that needs correcting.
