Commercial and industrial work covers TPO, PVC, EPDM, modified bitumen, built-up roofing, coatings, cold-applied and torch applications, metal roofing, energy-efficient and additional flat roofs, gutters, downspouts, coping metal, waterproofing, and tear-off.
DE Group also provides roof inspections, insurance-claim and storm-damage support, emergency repairs, traffic and sidewalk coatings, thermal scanning, hazardous-material and weight-and-pull testing, preventive maintenance, site sanitation, prefabrication of gutter and coping, flashing, chimney tops, and advisory work for contractors, engineers, and architects.
