What the job involves
A new roof on an extension or new build is specified as part of the overall project. The roofer’s scope usually starts once the rafters and boarding are in place: laying the underlayment, fitting battens, and installing the chosen covering.
Building Regulations Part L and Part C apply to all new construction. The covering has to hit specific U-values, the underlayment has to resist the passage of moisture, and the detailing at abutments and eaves has to handle wind uplift — all covered in BS 5534.
Glasgow — local context
Traditional material: Scottish slate and Welsh slate on sandstone tenements.
The city’s sandstone tenement stock uses natural slate as the traditional covering; West End and Park conservation areas impose material restrictions and Glasgow City Council guidance favours natural slate on re-roofs.
What changes the price

Timeline: Roofer’s portion of a new-build extension is usually 3–8 days depending on complexity.

Start my quote requestCommon questions
Who is responsible for Part L compliance — me or the roofer?
For a new build or extension, the person commissioning the work is the “relevant person” under Building Regulations. In practice the main contractor (or for a roof-only job, the roofer) takes responsibility for issuing the compliance certificate, often via CompetentRoofer self-certification.
Can I use a different covering from the rest of the house?
In most situations yes, but in conservation areas and on listed buildings the planning authority may require the extension roof to match the main house.
