Roofing Company in
Sharonville, OH

A 1970s home is likely on its second roofing system, which means the previous installation added a layer — and that layer may or may not need to come off before new shingles go on. Most jurisdictions allow one layer of shingles over an existing layer; two existing layers typically require a full tear-off before re-roofing. We also assess the deck condition beneath whatever is there, because 50-plus years of Ohio weather can soften areas of the original sheathing in ways that aren't visible until the shingles are off. And attic ventilation on homes from this era is frequently inadequate — we check it and address it as part of the project because it directly affects how long your new roof performs.

It depends on the system type, its age, and the nature and location of the leaks. TPO and EPDM membrane systems can often be repaired effectively at seam failures, penetration points, and drain surrounds if the overall membrane is still sound — repair is far less expensive than full replacement and can extend the system meaningfully. If the membrane has widespread adhesion failure, multiple seam openings, or significant ponding water from inadequate drainage, replacement becomes the more cost-effective answer. We inspect commercial roofs with the same thoroughness we bring to residential work, and we'll tell you honestly whether repair or replacement is the right call for your specific system — including what the cost comparison looks like over the next five years.

TPO (thermoplastic polyolefin) is a single-ply white membrane typically heat-welded at seams — highly reflective, energy-efficient, and now the most common choice for new commercial installations. EPDM (ethylene propylene diene monomer) is a rubber membrane, typically black, that has been the industry standard for decades — extremely durable, with well-understood repair procedures. Parker Roofing installs and repairs both TPO and EPDM systems. We'll match the recommendation to your building's specific drainage geometry, HVAC load, and budget.

Yes. For commercial property managers in Sharonville, we offer maintenance agreements that include scheduled spring and fall inspections, minor seam and penetration repairs, drain clearing, and a written condition report after each visit. The goal is to catch failing seams, pooling water conditions, and HVAC penetration deterioration before they become emergency calls — which are both more expensive to address and more disruptive to your tenants or operations. Ask us about commercial maintenance when you contact us and we'll explain what a program looks like for your specific building inventory.

Yes — particularly if your roof is more than 15 years old or if the storm included hail. Hail damage to asphalt shingles is often not visible from the ground: you're looking for granule displacement and soft spots in the shingle mat that indicate the impact has compromised the protective weathering layer. That damage doesn't cause leaks immediately — it accelerates wear and shortens the remaining life of the shingles. On a roof that's already in its final years, a storm hit can pull that timeline forward significantly. The inspection is free and takes less than an hour. If there's nothing to report, you've lost nothing. If there is claim-worthy damage, you'll want to know before the filing window with your insurance company closes.
