Flat & low-slope roofing
A low profile does not mean a simple roof. Water must leave slowly sloping surfaces through carefully planned routes.
01 / Considerations
Flat is a description, not a drainage plan
Low-slope roofs need falls toward suitable drains, scuppers or gutters. Persistent standing water deserves investigation of outlets, surface geometry and possible deflection. Drainage assessment should come before choosing a new covering, because changing the surface alone may leave the original problem in place.
02 / Considerations
Choose a system for the roof’s use
A commercial roof with equipment access has different demands from a small residential extension. Single-ply membranes and asphalt-based systems offer several approaches, but substrate condition, insulation, attachment and penetrations determine suitability. Check transitions where low-slope roofs meet walls or adjacent steep roofing.
03 / Considerations
Work from condition, not appearance
A tidy surface can conceal wet insulation, while a localized split may be repairable on an otherwise serviceable roof. Inspection and further investigation where needed help define the scope. Pair commercial roof planning with ongoing outlet and detail checks.
