Extension and kitchen roofs in Stamford

Replacing an extension roof in Stamford usually takes a few working days and rarely puts the kitchen out of action. We plan the strip so the room is weathertight each night, rebuild the roof with insulation to current guidance, and handle the approval paperwork across Lincolnshire where it applies.

What makes a good extension roof in Stamford?

Rooflights fitted after the roof was built are a frequent source of trouble in Stamford extensions. If the kerb was not formed properly or the membrane was simply sealed around the frame, leaks follow. Replacing the roof is the chance to rebuild every upstand to a proper standard.

Around Stamford, flat roofs are common on shops with flat-roofed rear stores below flats and on terraced streets with flat-roofed rear kitchens and bathrooms. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall.

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
  • New deck, vapour control layer and warm-roof insulation
  • Free survey of the roof, abutment and room below
  • 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.

How much does a new extension roof cost in Stamford?

£2,750–£4,800 for a 20 m² extension roof in EPDM with a new deck and insulation, at East Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

How do I know my extension roof needs replacing rather than repairing?

Repeated leaks, a soft deck, wet insulation or widespread cracking point to replacement. A single defect on a dry, sound roof can usually be repaired.

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.
