Commercial roofing is a different discipline from residential. Flat and low-slope systems (TPO, EPDM, PVC, modified bitumen, and built-up roofing) each have specific installation requirements and performance characteristics. Saint Olaf Roofing & Maintenance installs and repairs all of them across Saint Olaf.
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. Saint Olaf 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
Building Inspection
Our inspector walks your commercial roof and documents every issue: ponding areas, seam failures, flashing deterioration, clogged drains, and UV damage. Photos and measurements provided in a report you can share with your property manager or ownership.
Detailed Proposal
Commercial roofing proposals from Saint Olaf Roofing & Maintenance include detailed specs, phasing plan if applicable, tenant coordination plan, and a realistic timeline. One number, no surprises.
Commercial Installation
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.
