Your commercial roof is protecting your inventory, your equipment, your employees, and your revenue. A leak doesn't just damage the building. It shuts down operations. Allegan Roofing & Maintenance provides commercial roofing services that keep Allegan businesses covered and dry.
Ponding water is the number one cause of commercial roof failure. Water that doesn't drain within 48 hours degrades the membrane and insulation underneath. Allegan Roofing & Maintenance installs tapered insulation systems that create positive drainage to scuppers, drains, or roof edges, minimum quarter-inch per foot slope.
Our Commercial Roofing Process
Free Assessment
We inspect the entire commercial roof: membrane condition, seam integrity, flashing details, penetration seals, drain function, and insulation condition. Core samples reveal moisture levels in the existing system. You receive a detailed written report.
Scope & Estimate
We present options when they exist: repair vs. replace, TPO vs. PVC, 15-year vs. 20-year warranty. Each option is priced so you can make an informed decision based on your budget and building plans.
Expert Crew
Our commercial crew installs per manufacturer specifications and NRCA guidelines. Hot-air welded TPO seams tested with a probe at every joint. Flashing details custom-fabricated for your building's penetrations. Insulation installed to achieve minimum R-value per code.
Warranty Activation
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Allegan Roofing & Maintenance.
