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.

Bristol — local context

Traditional material: Welsh slate on Georgian terraces, Pennant stone on older buildings.

Clifton Village, Hotwells, and large parts of central Bristol are conservation areas with dense Georgian and early-Victorian terraces where slate re-roofs generally have to match the original material and course.

What changes the price

  • Covering material and underlayment specification.
  • Coordination with the main contractor and other trades.
  • Complexity — dormers, rooflights, solar provision.
  • Height, pitch, and scaffolding plan.

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

Common 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.

What does new roof (new build / extension) typically cost in Bristol?

A typical new roof (new build / extension) job in Bristol falls in the £95–£231/m² range, with the middle of the market around £147/m². Bristol’s labour and access factor (1.05× the national baseline) means prices run slightly above the UK average. Actual quotes vary with access, materials, and specifics of the job.

Are there any Bristol-specific things that affect price?

Clifton Village, Hotwells, and large parts of central Bristol are conservation areas with dense Georgian and early-Victorian terraces where slate re-roofs generally have to match the original material and course.
