M.D. Roofing & Sheet Metal relies on 2-ply SBS modified torch for reroofing and repairs. SBS or modified bitumen is a flexible rubber predominantly used on flat roofs. Recognized as the best in the roofing industry, SBS is 95% more often used by school, military, government and institutional buildings in Alberta and throughout Canada.
