Flat roof replacement in Dewsbury

We replace flat roofs on houses, flats and small commercial buildings in Dewsbury. The work covers everything from the timber deck up: falls set to drain, a warm-roof build-up where the room below is heated, upstands formed properly at walls and rooflights, and new trims and outlets. Building control is handled for you where it applies.

When should a flat roof in Dewsbury be replaced?

Selling or letting a property in Dewsbury can also prompt a replacement. A buyer's surveyor will usually flag a flat roof near the end of its life, and a recent replacement with written workmanship and material guarantees answers that question before it turns into a negotiation point.

Dewsbury's flat roofs are mostly on shops with flat-roofed rear stores below flats, with plenty on 1930s semis with flat-roofed garages and kitchen extensions too. 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 flat roof replacement cost in Dewsbury?

At Yorkshire and the Humber guide rates, a 20 m² extension roof in EPDM with a new deck and insulation comes to £2,650–£4,650 including VAT. The fixed price comes after a free survey for new and replacement roofs.

How long does it take to replace a flat roof?

A garage or single-storey extension roof is usually stripped and re-covered in one to three working days; larger, higher or more detailed roofs take longer. Weather sets the pace, because the deck must be dry before insulation and membrane go down.

We strip only as much as can be made weathertight that day, so the roof is never left open overnight. Expect noise and some vibration during the strip, a skip on the drive (or on the road with a permit) and ladders or a tower against the house. Rooms below stay usable, though it helps to clear shelves near the ceiling. Resin systems such as GRP smell strongly while they cure, so keep nearby windows closed that day. Two-storey roofs need scaffold, which goes up before we start and comes down after sign-off.

What's included?

  • Free survey of the deck, falls, edges and insulation
  • New membrane, upstands, edge trims and outlets
  • Strip-out of the old covering, with waste and skip
  • New deck, firrings and warm-roof insulation where needed

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.
