Flat roof replacement in Retford

If your flat roof in Retford has reached the point where patches no longer hold, a full replacement is usually the better spend. Our vetted roofing teams, working under S&K, rebuild garage, extension, dormer and commercial roofs across Nottinghamshire, using EPDM, GRP, torch-on felt or liquid systems chosen for the roof in front of them.

When should a flat roof in Retford be replaced?

Exposure matters too. Wind lifts tired edges, and repeated wetting and drying works at old joints, so roofs in exposed spots can wear faster than the same roof somewhere sheltered. Wherever your property is in Retford, a survey tells you whether the roof has years left or needs replacing now.

In and around Retford, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on lock-up garage blocks on estates. 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 much does a flat roof replacement cost in Retford?

For Retford we use East Midlands rates: £2,750–£4,800 is the guide for a 20 m² extension roof in EPDM with a new deck and insulation, VAT included. 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?

  • Strip-out of the old covering, with waste and skip
  • Building control handled where needed, plus a written workmanship guarantee
  • Fixed written quote listing the full build-up
  • Free survey of the deck, falls, edges and insulation

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.
