What this covers

New roof sections begin with the drawings, pitch and surrounding junctions.

An extension or new roof area is not simply a larger version of a repair. The roof needs to follow the confirmed design, structural build-up, pitch, drainage strategy and chosen covering while also connecting correctly to the existing building.

The roofing scope can include membrane and battens, tiles or another specified covering, ventilation, flashings, valleys or abutments, rooflights and roofline components. The construction details should follow the approved project specification rather than assumptions made from a photograph alone.

Typical project considerations

  • Confirmed drawings, dimensions and roof pitch
  • Chosen covering and required roof build-up
  • Junctions with the existing building
  • Drainage, gutters, outlets and roof-edge details
  • Rooflights, penetrations, ventilation and access requirements
