When should a flat roof in Consett be replaced?

A mineral felt roof laid decades ago may still look intact from the ground in Consett, yet have lost its chippings, cracked at the laps and pulled away at the upstands. Those faults let water track under the covering, so by the time a ceiling stain appears, the deck has often been wet for some time.

Consett's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on shops with flat-roofed rear stores below flats too. England averages roughly 870 mm of rain a year; the North East is drier than the west but cold and windy near the coast, so wind uplift and freeze-thaw are in the specification.

How much does a flat roof replacement cost in Consett?

For Consett we use North East rates: £2,600–£4,550 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.

Do I need building regulations approval to replace a flat roof?

Often, yes. Replacing the covering of a flat roof over a heated room is usually treated as renovating a thermal element, which brings insulation requirements and, in most cases, approval.

In England, if more than half of that roof is renovated, the whole roof should be upgraded towards a U-value of 0.16 W/m²K for homes (0.18 for non-domestic buildings) where that is technically, functionally and economically feasible, judged against a simple payback of 15 years. Approval comes from building control or self-certification through a registered competent person scheme. Structural changes, or a covering that adds 15% or more to the roof's weight, also need approval.

The other nations differ: most re-roofing in Wales needs approval, Scotland works through building standards and the building warrant, and in Northern Ireland you contact the district council's building control first. An unheated detached garage is not normally a thermal element. Planning permission is not usually needed if the roof looks much the same afterwards, though listed buildings and conservation areas are different. We handle approvals where needed; see building regulations.

What's included?

  • New membrane, upstands, edge trims and outlets
  • Building control handled where needed, plus a written workmanship guarantee
  • New deck, firrings and warm-roof insulation where needed
  • Strip-out of the old covering, with waste and skip

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 flat roof replacement cost in Consett?

£2,600–£4,550 for a 20 m² extension roof in EPDM with a new deck and insulation, at North East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Will a replacement make my roof higher?

Usually a little, if insulation is added above the deck. We check door thresholds, window sills, upstands and wall flashings at survey so the new level works.

Will a new flat roof be better insulated than the old one?

If it is over a heated room, yes. A full replacement usually has to be upgraded towards current insulation levels where feasible, and we build it as a warm roof with the insulation above the deck.
