Cost: roof flashings and built-in gutters
Two components of equal length can require very different work. Request shape, developed width, material, support and joints, including connections to existing work. Compare the completed component with access, removal and agreed checks.
Editorial update on 18 September 2026
Compare the whole component
Specify length, developed width, material, finish and shaped parts. Developed width is the flat width before folding, not the visible width. Compare joints and connections too.
Define repair scope
List removal, opening the covering, support preparation and reinstatement. Agree how work extends if hidden damage appears. Identify deliberately retained components.
Price access constraints
Clarify scaffolding, platform, temporary protection, waste and handover. A small component with difficult access can involve site costs separate from fabrication; request these explicitly.

Frequently asked questions
Must roof metalwork always use zinc?
Specify a material suited to the detail and existing work. The trade name does not determine every component.
Does water beneath a chimney prove flashing failure?
It calls for assessment of the junction and surrounding elements, not a conclusion about one piece.
What is a gutter’s developed width?
Its flat width before folding. With length and shape, it helps compare components.
Is sealing a leak always a permanent repair?
Ask for findings, the chosen solution and its limits. Temporary measures should be described as temporary.
