Any temporary in-house or professional flat roof repair should ideally be completed before winter.

Short-term Repair

Temporary flat roof repair to roll asphalt or modified bitumen roofing can be performed by maintenance crews. However, it is important to avoid the use of bituminous patching compounds (such as roofing tar) for repairs. These temporary repairs can eventually be harmful to building materials and difficult to remove at a later date.

Flat roofs are frequently used as platforms for mechanical equipment, signs, and braces. Consequently, leaks are a result of improper mounting and flashing. Avoid using the roof as a staging area for parapet, steeple, or mechanical repairs, where workers can be careless about protecting the surface.
