About Our Calvin Commercial Roofing Services
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. Calvin Roofing & Maintenance installs tapered insulation systems that create positive drainage to scuppers, drains, or roof edges, minimum quarter-inch per foot slope.
We offer annual and semi-annual maintenance contracts for Calvin building owners. Regular inspection catches small problems before they become expensive emergencies. Seam checks, flashing inspection, drain clearing, and minor repairs, all documented with photos in a maintenance report.
