Dormer roofs in Lofthouse

Across Lofthouse and the wider West Yorkshire, we rebuild dormer flat roofs with insulation to current guidance and new trims that throw water clear of the window. Each roof is surveyed first, and the fixed price comes in writing. Every re-roof carries a written workmanship guarantee.

What does a dormer roof in Lofthouse need?

A dormer roof that has been patched several times in Lofthouse often has layers of old repairs that hide the real fault. Stripping back to the deck shows what has been going on, and lets the team rebuild the back-edge abutment properly rather than sealing over it again.

Around Lofthouse, flat roofs are common on 1960s and 1970s link-detached houses with flat-roofed garages and porches and on 1930s semis with flat-roofed garages and kitchen extensions. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

How much does a new dormer roof cost in Lofthouse?

For Lofthouse we use Yorkshire and the Humber rates: £1,350–£2,500 is the guide for an 8 m² GRP dormer roof including scaffold, VAT included. The fixed price comes after a free survey for new and replacement roofs.

JobGuide price inc VAT
Dormer (8 m²), GRP, scaffold£1,350–£2,500
Single garage (18 m²), EPDM rubber£1,500–£2,650
Extension (20 m²), GRP, new deck + insulation£2,850–£5,100

How long does a dormer roof replacement take?

The roofing itself typically takes one to three days, with scaffold going up before and coming down after. Allow a few extra days overall for the scaffold.

The room under the dormer stays usable, though it will be noisy during the strip-out, and dust can fall through gaps around the ceiling. Moving furniture away from the window helps. Scaffold usually needs space on the drive or garden, and sometimes a pavement licence. GRP has a strong smell while it cures, so keep the dormer windows shut on the day it is laid.

What's included?

  • Written workmanship guarantee, with building control handled where needed
  • New membrane, drip trims and back-edge abutment under the tiles
  • Scaffold with edge protection, priced in the quote
  • Free survey of the dormer roof, cheeks and main roof junction

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a new dormer roof cost in Lofthouse?

£1,350–£2,500 for an 8 m² GRP dormer roof including scaffold, at Yorkshire and the Humber guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Will insulating my dormer roof make it higher?

Yes, by the insulation thickness. We plan the build-up so the new roof still sits correctly under the main roof tiles at the back edge.

Is a dormer roof cheaper than a garage roof?

Not by as much as the size suggests. Scaffold and the extra detailing at height mean a small dormer roof often costs about the same as a single garage roof.
