Extension and kitchen roofs in Harrogate

For homeowners in Harrogate with an older single-storey extension, the roof is often the first part to fail. We look at the whole picture at survey: the deck, the fall, the house wall junction, any rooflights and the ceiling below. Then we price the replacement in writing, with no obligation.

What makes a good extension roof in Harrogate?

Selling a house in Harrogate with a tired extension roof can raise questions in the buyer's survey. A recent replacement, with building control sign-off where needed and written guarantees, gives a buyer confidence and removes a likely point of negotiation.

In and around Harrogate, flat roofs are typically found on newer estates where the first extension roofs are now being replaced, and on shops with flat-roofed rear stores below flats. 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 long will my kitchen be disrupted by a new roof?

Most single-storey extension roofs are replaced in two to four working days, depending on size, rooflights and weather. The kitchen usually stays in use throughout.

Expect noise during the strip-out, and occasional dust through gaps around old rooflights, so it helps to cover worktops and move anything fragile off high shelves. We strip only what we can make weathertight by the end of each day. If a rooflight or lantern is being lifted and refitted, there may be a temporary cover over the opening for a short time. Resin systems smell while they cure, so keep the windows below the roof closed on that day.

What's included?

  • Falls set away from the house wall
  • Staged strip-out so the room stays weathertight
  • Building control handled where needed, and a written workmanship guarantee
  • New abutment upstand and flashing, plus rebuilt rooflight kerbs

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.

Where the work needs approval it goes to North Yorkshire Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does a new extension roof cost in Harrogate?

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

Will a new extension roof sit higher than the old one?

Usually, by the thickness of the added insulation. We check the height against the upstairs window sills, door thresholds and wall flashings at survey so everything still works.

Is EPDM or GRP better for a kitchen extension?

Neither is better in every case. EPDM suits simple rectangular roofs with few details, while GRP is often chosen where there are rooflights, corners or occasional foot traffic.
