Roofing

Roof steelwork, trusses and sheeting

Trusses, purlins and sheeting for a roof of any span and any height — new build or re-roof. Both profiles are cut to length in the workshop before they leave it, and the flashings are folded to match the roof they go on.

What to send for a roofing quotation

  • The floor area to be covered, and the roof pitch you want.
  • Whether this is a new build or a re-roof, and whether the walls are already up.
