Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Glen Haven Roofing & Maintenance has the training and equipment to handle all of it across Glen Haven.
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. Glen Haven 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
Commercial Roof 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
Commercial roofing proposals from Glen Haven Roofing & Maintenance include detailed specs, phasing plan if applicable, tenant coordination plan, and a realistic timeline. One number, no surprises.
Expert Crew
Factory-trained crews using proper equipment, hot-air welders for TPO/PVC, torch equipment for modified bitumen, and adhesive systems for EPDM. Every seam, flashing, and penetration detail inspected before we leave.
Final Inspection
Your commercial roof gets a detailed completion package: as-built documentation, warranty certificates, maintenance recommendations, and emergency contact information for Glen Haven Roofing & Maintenance.
