Understand The Role Of The Detail
Flashing allows the roofing to connect at changes in direction and around interruptions. A curb, parapet or pipe can create a water-entry point if that connection deteriorates or separates. The condition of the nearby open roof surface does not establish that the detail is sound.
The repair needs to suit the membrane or metal system and the surfaces it joins. Different materials and movement conditions can require different methods.
Investigate The Connection
Open edges, damaged corners and failing terminations may be visible signs. The assessment should also consider how the detail is constructed and whether the supporting materials remain serviceable. An external cover-up may leave an unsuitable connection beneath it.
Changes to equipment or penetrations can affect existing flashing. Mention recent work so the inspection can consider what changed without assuming that timing alone proves the cause.
Include Related Materials
A flashing repair may extend into adjacent membrane, metal or wall surfaces to make a suitable connection. Deterioration or moisture can increase the work beyond the visibly damaged edge.
Where equipment or another building system needs attention, coordination may be necessary. The scope should identify that relationship instead of assuming all associated work is part of a simple roofing patch.
Discuss The Location
Tell us which building feature is involved and whether water is appearing inside. Existing photos or roof records can help locate the area. The assessment determines the compatible repair and its practical limits.
