Commercial Roof Maintenance & Inspections
Comprehensive commercial flat roof inspections & preventative maintenance programs across Windsor-Essex. Photographic audit reports & drain clearing.

Detailed Scope & Specifications
Roof replacement is one of the largest capital expenditures a commercial property owner or facility manager will ever face. Windsor Roofing Pros provides structured commercial roof maintenance programs and 21-point photographic roof inspections that detect vulnerabilities early, preventing premature capital replacements. Across Windsor, Tecumseh, and Essex County, routine maintenance doubles the operational service life of commercial flat roof systems.
What Our 21-Point Commercial Roof Inspection Evaluates Our certified commercial inspectors walk every square foot of your facility's roof surface, documenting: 1. **Membrane Integrity**: Seam adhesion, field puncture resistance, blistering, alligatoring, and surface granule retention. 2. **Perimeter Flashings & Parapets**: Coping metal joints, counter-flashing sealants, and termination bar fasteners. 3. **Drainage Infrastructure**: Internal roof drain baskets, clamping rings, through-wall scuppers, and conductor heads. 4. **Rooftop HVAC Curbs & Penetrations**: Pitch pockets, rubber pipe boots, gas line supports, and skylight curbs. 5. **Ponding Water Zones**: Measuring standing water depth and evaluating substrate deflection. 6. **Deck & Structural Underside**: Inspecting interior steel pan, concrete, or wood decking for rust, water staining, or structural deflection.
Scheduled Preventative Maintenance Program - **Bi-Annual Scheduled Service**: Comprehensive spring and autumn visits to inspect assemblies, remove storm debris, and prepare for seasonal weather extremes. - **Debris & Drain Clearing**: Clearing leaves, vegetation, silt, and foreign debris from internal drains and scuppers to ensure immediate water drainage. - **Preventative Caulking & Sealing**: Touching up pitch pockets, resealing termination bars, and servicing worn flashings before leaks start. - **Asset Management Reports**: Providing high-resolution digital photographic documentation, condition ratings, and projected lifespan estimates for condo boards, investors, and capital reserve funds.
