Fully licensed Ohio commercial contractor. Every project is engineered to OBC 2023, IECC 2021, ASCE 7-22, and OSHA 1926 requirements — with written documentation to prove it.
Commercial roofing is engineering, not just labor. We select the right system for your building's occupancy, structure, wind zone, and energy code requirements — then install it to the letter.
Ohio law limits re-roofing layers. OBC 1510.3 and local ordinances typically prohibit more than two total roof layers. We always assess existing layers and tear off when required — no exceptions.
Heat-welded seams create a watertight monolithic membrane. Can be fully adhered, mechanically fastened, or ballasted per ASCE 7-22 wind zone. Ohio's most popular commercial flat roofing system.
Ohio Code & Compliance Notes
IECC 2021 CZ5 requires minimum R-25 ci insulation beneath membrane
Wind uplift per ASCE 7-22 — mechanically fastened pattern must be engineered
OBC 1507.12 governs TPO installation on commercial structures
FM 4470 rated assembly required on qualifying occupancies
Single-ply rubber membrane with exceptional elongation (300%+) — handles substrate movement without cracking. Available in black (heat absorbing) or white (reflective). Fully adhered, mechanically fastened, or ballasted systems available.
Ohio Code & Compliance Notes
OBC 1507.11 governs EPDM single-ply membrane installation
Black EPDM may not satisfy IECC 2021 cool roof requirements — verify with COMcheck
Seams must be lapped and bonded per NRCA guidelines
Ohio Fire Code (OFC) requires Class A fire rating — use UL-listed assembly
Asphalt-based polymer-modified membrane providing excellent puncture resistance and multi-layer waterproofing. SBS (styrene-butadiene-styrene) provides rubbery flexibility in cold temps — important for Ohio winters. APP (atactic polypropylene) adds UV resistance.
Ohio Code & Compliance Notes
OBC 1507.9 governs built-up and modified bitumen roofing
Torch application requires fire watch and AHJ notification in some Ohio municipalities
Vapor retarder per OBC 1408 required beneath insulation in conditioned buildings
Granule-surfaced cap sheet provides Class A UL rating
3–5 alternating layers of bitumen and reinforcing felts topped with a flood coat and aggregate (gravel or slag). Proven system with 100+ year track record. Excellent for rooftop HVAC-heavy applications where membrane puncture risk is elevated.
Ohio Code & Compliance Notes
OBC 1507.9 governs BUR systems — aggregate ballast depth must meet fire rating requirements
OSHA 1926.502 full fall protection required — kettle operations require additional safety plan
Cold-weather application restrictions — bitumen cannot be applied below 40°F
Drainage design critical — OBC 1503.4 minimum 1/4" per foot slope required
Heat-welded single-ply membrane with excellent chemical, fire, and UV resistance. The go-to for restaurant and food service roofs where grease-laden exhaust can degrade TPO and EPDM. Higher upfront cost, lower long-term maintenance.
Ohio Code & Compliance Notes
OBC 1507.13 governs PVC membrane installation
Chemical resistance makes it preferred by Ohio Dept. of Health for commercial kitchen roofs
IECC 2021 compliant — white PVC meets cool roof reflectance requirements
FM 4450 rated system required on fire-sensitive occupancies
Steel or aluminum panels with raised seams that interlock without exposed fasteners. Exceptional wind resistance (tested to 140+ mph), Class A fire rated, and recyclable at end of life. Often used on commercial buildings, churches, and institutional facilities.
Ohio Code & Compliance Notes
OBC 1507.4 governs metal roofing on commercial structures
ASCE 7-22 wind uplift calculations required — standing seam clips must be engineered
Thermal movement must be accommodated — floating clip design required on runs over 30'
Dissimilar metal corrosion prevention required at fastener and flashing connections
Two-component polyurethane foam sprayed directly to the substrate — self-flashing around all penetrations and curbs. Closed-cell foam provides R-6.5 per inch. Topped with silicone or acrylic elastomeric coating for UV and weather protection. Renewable — recoat every 10–15 years extends life indefinitely.
Ohio Code & Compliance Notes
OBC 2603 governs foam plastic insulation — thermal/ignition barrier required in occupied spaces
EPA Section 608 certification required for handling refrigerants near rooftop HVAC during application
Ohio Fire Code requires Class A rated topcoat system — silicone coating is standard compliant option
IECC 2021: SPF typically achieves R-25+ in 3–4" thickness — often exceeds minimum energy code
Commercial projects carry higher stakes — stricter codes, mandatory engineering, and OSHA requirements. We deliver full documentation on every job.
Commercial cladding must satisfy fire ratings, energy codes, and moisture management requirements far beyond residential standards. We know the code and install accordingly.
Fiber Cement Panel
Class A fire rated — commercial & multi-family
Metal Panel Cladding
Steel or aluminum — factory PVDF finish
Engineered Wood
ESR-certified, factory primed, field painted
Phenolic & Composite
High-end commercial aesthetic, low maintenance
Commercial drainage is a code-driven engineering exercise — not just hanging gutters. OBC 1503.4 requires drainage and overflow systems sized to actual rainfall loads, not guessed.
Northeast Ohio rainfall intensity: Northeast Ohio's 100-year, 1-hour rainfall is approximately 3.3–3.8 inches. We size all commercial drainage systems to handle this load with properly engineered overflow protection per OBC 1503.4.1.
