Flat roofs behave differently from steep-slope shingle roofs. Water drains more slowly, penetrations and seams become especially important, and the roof membrane has to be matched to the building and substrate. Cheshire Roofing provides flat-roof inspection, repair and replacement services in Sarnia-Lambton.
TPO roofing
Thermoplastic polyolefin (TPO) is a light-coloured single-ply roofing membrane used on many low-slope commercial and residential applications. It can be mechanically fastened or fully adhered depending on the system design.
Drainage and details
Ponding water, blocked drains, failed seams, punctures, perimeter details and penetrations are common places to investigate when a flat roof develops problems.
Repair before damage spreads
A small membrane or flashing failure can allow water to move within the roof assembly. Early inspection can reduce the chance that a localized repair turns into a larger replacement.
