Flat roofs, low-slope systems, and full replacements for storefronts, strip malls, office buildings, and other commercial properties throughout Greater Cincinnati — backed by a 5-year workmanship warranty on every job.
Know the Warning Signs
Commercial flat roofs fail differently than residential roofs — and they fail quietly. Ponding water, separated seams, and slow leaks can go unnoticed for months before causing interior damage, business interruption, or expensive structural repairs.
Parker Roofing inspects, repairs, and replaces commercial roofing systems throughout Greater Cincinnati. We work around your schedule, give honest assessments, and stand behind every job we complete.
Schedule a Free InspectionWater that doesn't drain within 48 hours after rain is the #1 accelerator of flat roof deterioration and the leading cause of membrane failure.
Ceiling stains, wet insulation, or visible drips inside your building mean water has already breached the roofing system and is causing hidden damage.
Blistering on TPO or EPDM membranes signals trapped moisture or adhesion failure — a sign the system is breaking down from within.
Seams and lap joints are the most vulnerable points on any flat roof. Lifted or open seams give water a direct path beneath the membrane.
Flashing around HVAC curbs, drains, parapets, and skylights deteriorates over time. Failed flashing is one of the most common sources of commercial roof leaks.
HVAC installation, service foot traffic, and equipment vibration can puncture or compress membranes — damage that often isn't visible until a leak shows up inside.
Commercial Roofing Systems
We install and repair the most proven commercial flat and low-slope roofing membranes available, using quality materials from trusted manufacturers. From single-ply replacements to targeted repairs, we handle every aspect of commercial roof work.
Repairs & Storm Damage
Not every commercial roof needs full replacement. We assess your existing system honestly and perform targeted repairs when they're the right call — seam repairs, membrane patching, flashing replacement, and drain service. When storm damage is involved, we handle the entire insurance process so you don't have to.
Flat Roofing Systems
We work with the two most proven commercial flat roofing membranes and help you choose the right fit based on your building's size, slope, use, and budget. All systems are installed to manufacturer specs and backed by our 5-year workmanship warranty.
Thermoplastic polyolefin (TPO) is one of the most widely installed flat roofing systems today. White, heat-welded seams, energy-efficient, and resistant to UV, punctures, and chemical exposure — ideal for most commercial buildings.
EPDM (ethylene propylene diene monomer) is a proven synthetic rubber membrane known for durability, flexibility in extreme temperatures, and long service life. Often lasting 20–30 years when properly installed and maintained.
Not every roof needs to be replaced. We inspect your existing system and perform targeted repairs — seam re-welding, membrane patching, flashing replacement, and drain service — to extend system life at a fraction of replacement cost.
HVAC curbs, drains, skylights, vents, and parapet walls all require properly installed flashing. We repair and replace deteriorated commercial flashing as a standalone service or as part of a full replacement.
Annual or post-storm commercial roof inspections help catch problems early. We provide written inspection reports with photographs for property managers, building owners, and insurance documentation.

Request a Commercial Quote 513-729-2770We install TPO membrane and EPDM rubber flat roofing systems — two of the most proven commercial flat roof membranes available. We also install asphalt shingle roofing on commercial buildings with steeper pitches. We help you choose the right system for your building's slope, size, use, and budget.
It depends on the age of the system, the extent of damage, and how much usable life remains. Isolated seam failures, minor punctures, or flashing problems are usually repair candidates. Widespread membrane deterioration, significant ponding, or a system approaching end of life is typically a replacement candidate. We give you an honest written assessment after inspection — we don't push replacements when a repair will do the job.
TPO membranes typically last 15–25 years. EPDM rubber roofs often last 20–30 years with proper maintenance. Actual lifespan depends heavily on drainage quality, installation quality, foot traffic, and how quickly problems are addressed when they appear.
Yes — flat and low-slope roofing systems are specifically engineered for commercial applications. They're cost-effective (requiring less material than pitched systems), provide accessible space for HVAC equipment, and are easy to inspect and maintain. Modern membrane systems offer excellent weather protection and long service life when properly installed and maintained.
Yes. We schedule commercial work around your operations whenever possible and communicate proactively throughout the project. For larger jobs, we can phase the work to minimize disruption to tenants or customers. Our goal is to get your roof done right with as little impact on your business as possible.
Yes. We inspect storm-damaged commercial roofs, document everything with photos and a written report, and support you throughout the insurance process. We work directly with adjusters when needed to ensure the full scope of damage is captured — not just the obvious surface problems.
Our Guarantee
We stand behind our work. If our workmanship fails within 5 years, we come back and fix it. Note: repairs on a roof we've assessed and recommended for full replacement are not covered under this warranty.
What Customers Say
"Can't say enough good things. They were able to get someone out for an estimate right away. I had multiple points of damage and they completed the repairs in the same day. Everyone was friendly and showed me pictures during the repair to keep me in the loop."
"Great company to work with and they stood behind their work. Not only did they do a great job with the roof installation, but when there was a minor problem, the owner came out and addressed it immediately. Definitely a company I would recommend."
"What made Mike and Tonia stand out is their personal touch. Mike got on a ladder and held roofing samples up so we could see how they'd look on our house. What came out of it was a beautiful roof that truly exceeded our expectations."
