Commercial roofing replaces or maintains the flat membrane systems on office buildings, warehouses, and retail properties.
These systems consist of a roof deck, insulation, a single-ply membrane like TPO, EPDM, or PVC, and flashings around parapets and penetrations.
Modified bitumen or built-up roofing systems offer alternatives, applied in layers with adhesive or bitumen.
Each type carries different warranty terms (15–30 years) and handles freeze-thaw stress differently.
TPO resists UV best; EPDM is affordable; modified bitumen suits buildings with roof-deck movement.
Proper ventilation and sealing prevent damage in Minneapolis winters. Heavy snowfall, ice dams, and freeze-thaw cycles destroy membranes with poor flashing.
Roof coatings extend aging membranes 5–10 years without full replacement. We follow Minnesota building code with manufacturer-rated adhesives and fasteners.
