TPO, EPDM, Modified Bitumen, Metal & Built-Up — fully permitted and OBC compliant.
From small retail strip centers to multi-unit apartment complexes, Demore Exterior Solutions handles commercial roofing in Niles with the expertise, licensing, and code knowledge that commercial projects demand. Every installation is engineered for Northeast Ohio's demanding climate — heavy snow loads, lake-effect ice, and high-wind events.
Commercial Site Assessment & Moisture Survey
We conduct a thorough commercial roof assessment including infrared or nuclear moisture surveys to detect trapped moisture in existing insulation — critical before any re-roofing decision.
Engineering Review & System Selection
We evaluate building occupancy, structural capacity, wind zone, drainage, and energy code requirements to specify the correct roofing system — TPO, EPDM, modified bitumen, metal, or built-up.
Commercial Plan Submittal & Permitting
Full commercial permit application submitted with wind uplift calculations, material data sheets, and energy compliance documentation (COMcheck) where required.
Existing System Removal & Decking Inspection
Existing roofing removed per local ordinance (one-layer maximum often required). Structural decking inspected; deteriorated sections replaced and documented.
Vapor Retarder Installation
Where required by OBC 1408 and climate zone, vapor retarder installed before insulation to control moisture migration in the roofing assembly.
Insulation Installation (R-Value Compliance)
Polyisocyanurate or other code-approved insulation installed to achieve required R-value per IECC 2021 commercial energy code — minimum R-25 continuous in Climate Zone 5 (Northeast Ohio).
Membrane or Surface Installation
Primary roofing membrane (TPO, EPDM, mod-bit) or surface (standing seam metal, built-up) installed per manufacturer's FM/UL-listed assembly specifications.
Flashing, Penetrations & Edge Metal
All penetrations, curbs, HVAC equipment, drains, and perimeter edge metal flashed and secured per OBC 1503 and manufacturer specifications.
Drainage Verification
All drains, scuppers, and overflow drains confirmed to meet OBC 1503.4 requirements. Drainage calculations verified for code compliance.
Fall Protection Compliance & OSHA Closeout
Written OSHA 1926.502 fall protection plan maintained throughout. Site cleared, all penetrations sealed, inspections coordinated with AHJ (Authority Having Jurisdiction).
Special Inspections & Final Signoff
Third-party special inspections coordinated where required per OBC Chapter 1705. Final building department inspection obtained. Warranty documentation provided.
TPO (Thermoplastic Polyolefin)
Energy Star rated white membrane — excellent for flat roofs. Fully adhered, mechanically fastened, or ballasted per wind zone.
EPDM (Rubber Membrane)
Industry-proven 40+ year lifespan. Excellent temperature flexibility for Ohio freeze-thaw cycles.
Modified Bitumen
Asphalt-based with polymer modification. Ideal for low-slope applications with rooftop traffic.
Standing Seam Metal
50+ year lifespan. Concealed fastener system eliminates penetration points. Class A fire rated.
Built-Up Roofing (BUR)
Multi-ply redundancy for maximum protection on demanding occupancies.
Metal panel, fiber cement, and composite cladding — fire-rated, energy-code compliant.
Commercial siding in Niles must meet fire rating, energy code, and moisture management requirements far more stringent than residential standards. Demore Exterior Solutions brings full OBC knowledge and commercial installation experience to every project.
Commercial Exterior Assessment
Full building envelope assessment identifying moisture intrusion, failed cladding, code deficiencies, and energy performance gaps. Occupancy type and fire rating requirements determined.
Fire Rating & Occupancy Review
Exterior wall assembly fire rating requirements per OBC Table 602 verified. IBC Section 1403 weather protection provisions reviewed for the specific occupancy and construction type.
Commercial Permit Submittal
Permit application submitted with product specifications, fire test data, wall assembly details, and energy compliance documentation as required by the local AHJ.
Existing Cladding Removal
Existing siding removed; sheathing and structure inspected for moisture damage, decay, and code deficiencies. All hazardous material protocols followed (asbestos, lead paint surveys performed where applicable).
Water-Resistive Barrier & Drainage Plane
Commercial-grade WRB installed per OBC 1403.2. Drainage plane and weep details installed to direct any incidental moisture to the exterior — critical for long-term performance.

Engineered drainage systems sized to OBC 1503.4 — protecting your building envelope and foundation.
Commercial drainage systems in Niles must handle significantly higher water volumes than residential, with overflow protection and stormwater compliance requirements that residential gutters don't face. Our commercial gutter installations are engineered, not guessed.
Drainage Load Calculation
Roof area, pitch, and local rainfall intensity data used to calculate required gutter and downspout sizing per OBC 1503.4 and ASPE Plumbing Engineering Design Handbook.
Overflow Protection Design
Overflow drains or scuppers sized and positioned per OBC 1503.4.1 to prevent structural overload in the event of primary drain blockage — critical for flat and low-slope commercial roofs.
Commercial Permitting
Permit pulled where required for commercial gutter and drainage systems. Drainage calculations submitted with application where required by local AHJ.
Existing System Removal
Old gutters, downspouts, and failed drainage components removed. Fascia and structural attachment points inspected and repaired as needed.
Commercial Gutter Fabrication

Heavy-Duty Hanger Installation
Commercial-grade hidden hangers installed at 16" OC (exceeding the 24" residential standard) with stainless or galvanized fasteners to handle Northeast Ohio ice and snow loads.
Downspout Sizing & Routing
