Roofing That Works With the Wider Project

Because JCB also undertakes extensions, conversions and structural carpentry, the roof can be planned as an integral part of the build rather than an isolated stage.

Roofing May Include

  • Beams, joists, rafters and trusses
  • Roof and loft-space insulation
  • Battens, slates and tiles
  • Flat-roof deck and membrane systems
  • Repairs to associated timber and finishes
