Quote: zinc or steel roof
E.g.: standing-seam zinc roof, extension or low-pitch roof
State whether the roof covers heated living space, an extension or an unheated outbuilding. Provide drawings, dimensions, openings and known appearance constraints. Beyond the metal choice, request the full roof build-up and confirmation that it suits the building.
Identify the proposed system
ArcelorMittal distinguishes covering profiles, sandwich panels and waterproofing supports. Request the exact reference: a sheet supporting a membrane is not necessarily the finished covering. Clarify included layers and intended use.
Check the zinc support
VMZINC identifies incompatible supports. Have contact materials and separation layers checked for the selected product. Request a section drawing and manufacturer instructions, especially where an old support remains.
Define moisture control
Ventilation depends on the system: ZINC PLUS allows certain unventilated warm-roof build-ups, with vapour-control and condensation-drainage requirements. This does not apply to all zinc. Have the build-up checked for the indoor use.
Describe expected performance
Identify occupied rooms beneath the roof and expectations for rain noise, heat, insulation and appearance. Request evidence for the proposed assembly. Sheet thickness or the presence of insulation alone does not establish comfort.
Plan details and follow-up
List fixings, metal movement, penetrations, edges and drainage junctions. Agree checks at handover and maintenance documents. Check municipal constraints before changing the roof’s appearance.

On quotation
A bare covering profile and an insulated panel include different work. Compare equivalent build-ups, required performance and preparation. Separate covering, support, insulation, junctions and site services before comparing area rates.
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
Is steel always cheaper?
Cost depends on the complete system and included work. Compare equivalent scope.
Must zinc always be ventilated underneath?
It depends on build-up and product. Ask for the specified solution to be justified.
Does an insulated panel guarantee comfort?
Check whole-assembly performance and junctions; the product description alone is insufficient.
Does low weight remove the need to check the structure?
No. Have its condition and suitability for project loads assessed.
