Quote: roof flashings and built-in gutters
E.g.: leaking box gutter, zinc chimney cladding

Locate the component: built-in gutter, valley between slopes, chimney flashing or edge covering. Describe water marks and when they appear. A precise request helps distinguish a local detail repair from wider roofing work.
Name the component and its function
A gutter collects water; a valley is the recessed meeting of roof slopes; flashing joins elements such as roof and chimney. Request a map of retained and replaced parts. Not every roof detail necessarily needs renewal in zinc.
Find the cause before fabrication
Buildwise highlights sensitive roof junctions. Have the full connection checked, including adjacent covering and support. A water mark beneath a dormer does not identify metal flashing as the sole cause.
Allow for metal movement
VMZINC describes expansion joints that accommodate thermal movement in gutters. Ask how the proposed system allows this movement. The component and dimensions determine the solution; an added bead of sealant does not establish a durable repair.
Check support and water flow
Assess support condition, contact materials, joints and outlets to downpipes. For a built-in gutter, ask what happens if the main outlet blocks. Define necessary masonry or covering work around the detail.
Document the intervention
Request photographs of opened areas and completed junctions, planned checks and maintenance instructions. Distinguish temporary protection from a final repair. Access arrangements should not expose occupants to an unprotected roof edge.

On quotation
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.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
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.
