Flat roof replacement in Yate

For homeowners and landlords in Yate, replacing a flat roof is a once-in-a-generation job, so the specification matters more than the speed. We set out the full build-up in writing, from deck and vapour control layer to insulation and membrane, and our teams follow it on site. Guide prices are online; the fixed price follows the survey.

When should a flat roof in Yate be replaced?

Selling or letting a property in Yate 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.

Around Yate, flat roofs are common on bungalows with flat-roofed side extensions and dormers and on low-rise post-war blocks of flats. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

How much does a flat roof replacement cost in Yate?

For Yate we use South West rates: £2,900–£5,050 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.

Should I overlay my old flat roof or strip it fully?

Strip it fully if the deck is soft, the insulation is wet or the falls are wrong; an overlay only suits a dry, sound roof that already drains well. Covering a wet roof traps the moisture, and rot carries on out of sight.

An overlay also raises the roof level, eating into upstand height at walls and door thresholds, and every layer adds weight. In England, a covering that adds 15% or more to the roof's weight needs building control approval. Signs it is time to replace rather than repair:

  • ponding that lingers long after rain
  • blisters, cracking or crazing across wide areas
  • bare bitumen where the mineral chippings have gone
  • split laps and lifted upstands or flashings
  • damp ceilings, or a deck that has gone soft
  • leaks that return after each repair

A single defect on an otherwise dry roof can usually be put right with a repair. If you're unsure, a survey settles it, and our guides to overlay or strip and repair or replace go further.

What's included?

  • New deck, firrings and warm-roof insulation where needed
  • Fixed written quote listing the full build-up
  • Free survey of the deck, falls, edges and insulation
  • Building control handled where needed, plus a written workmanship guarantee

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 Yate?

£2,900–£5,050 for a 20 m² extension roof in EPDM with a new deck and insulation, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

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.
