Dormer roofs in Mold

A dormer roof in Mold may be only a few square metres, but it sits high up and meets a tiled roof on several sides. That makes the edges the hard part. Our quotes for dormer roofs set out the access, the insulation, the membrane and every abutment, with building control handled where needed.

What does a dormer roof in Mold need?

If your dormer in Mold was added years ago with a basic felt roof and little insulation, it will tend to fail at the edges first, and they leave the loft room cold in winter and hot in summer. A warm-roof replacement deals with both problems at once.

Around Mold, flat roofs are common on bungalows with flat-roofed side extensions and dormers and on terraced streets with flat-roofed rear kitchens and bathrooms. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

How much does a new dormer roof cost in Mold?

Guide price in Mold: £1,300–£2,450 for an 8 m² GRP dormer roof including scaffold, including VAT at Wales rates. The fixed price comes after a free survey for new and replacement roofs.

JobGuide price inc VAT
Dormer (8 m²), GRP, scaffold£1,300–£2,450
Single garage (18 m²), EPDM rubber£1,450–£2,600
Extension (20 m²), GRP, new deck + insulation£2,750–£4,950

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?

  • New membrane, drip trims and back-edge abutment under the tiles
  • Warm-roof insulation and a vapour control layer
  • Written workmanship guarantee, with building control handled where needed
  • Strip-out of the old covering and deck repairs

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

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.
