Commercial Roof Maintenance Programs Across the Riverbend
Most commercial roof manufacturers require documented annual maintenance to keep their warranties valid. Skip it and a $50,000 TPO replacement becomes a $50,000 out-of-pocket replacement when the manufacturer voids coverage. Trill Roofing runs commercial roof maintenance programs across Godfrey, Alton, Edwardsville, and the Riverbend – annual or semi-annual scope, written reports, and proactive repair scheduling. Programs cover TPO, EPDM, modified bitumen, and standing seam metal commercial roofs.

- Full roof walk: Surface inspection, ponding water mapping, debris removal, biological growth check.
