A roof that is nearly level or slightly pitched is called a low-slope roof. Whether you need a new installation or a major repair, ALPHA Roofing has the experience and knowledge to provide the best low-slope roofing system available. There are many configurations to choose from, with several deck types, insulation requirements, membrane and other factors.

 • SBS Heat-Welded Membranes are the most common material ALPHA Roofing uses in flat roof applications. SBS membranes are asphalt based, fiberglass reinforced polyester membranes treated with Styrene-Butadiene-Styrene polymers to impart ''rubber'' type qualities. 

  Low-slope roofing must be handled with care and attention to detail. Problems with low-slope roofs are common and more difficult to diagnose than pitched roof problems because the path of water leakage through flat roofs is often quite hard to trace. If you are looking for expert advice and quality installation contact Alpha Roofing. ​Our professional customer service, combined with our pricing rates, is unmatched by any competitor and makes us your best choice in Winnipeg.
