A roof edge is the boundary of a roof plane and often contains several interacting components. Visible finishing, underlying fixing and the connection to the roof covering may perform different functions. It is therefore more than the profile visible from outside.
When discussing repair or renewal, ask which components are meant by roof edge. An instruction may cover only finishing or also affect the junction behind it. Without clarification, the point where new work meets the existing roof remains unclear.
An altered assembly may change the available space at the edge. Have those relationships assessed before assuming retention is straightforward. Afterwards, record which components were renewed and which remained existing, connected to an identifiable location on the roof overview.

Frequently asked questions
Is a roof edge the same as edge trim?
No. Edge trim is one possible component of the perimeter finish.
Can additional insulation affect the edge?
Yes, it can. Have levels and junctions assessed with the proposed assembly.
