Flat roofing in Olton

Planning your flat roof in Olton

Live in a conservation area or a listed building in Olton? Check with Solihull Council before changing the outside of your home. Otherwise the main rules for your flat roof are Building Regulations, and we'll explain at the survey which certificates you'll receive.

Replacing a flat roof's membrane over more than half the roof normally means upgrading its insulation.
Rotten decking is only found once the old roof is stripped, and any repair is agreed in writing first.
The target U-value for a renovated roof is 0.16 W/m²K, where that's practical.

Which option fits your home?

Warm-roof insulation upgrade

Rigid insulation boards are laid on top of the deck, under the new membrane, so the timbers stay warm and the risk of condensation drops. A warm roof raises the roof level slightly, which affects upstands, door thresholds and window cills. We check those details at survey before recommending it.

EPDM rubber roof

A single sheet of synthetic rubber bonded to the deck, often in one piece with no joints on smaller roofs. EPDM handles temperature changes well, is quick to lay and needs little maintenance. It's a good all-round choice for garages and extensions, though it has a plain black finish and needs care around complex details.

How much should you budget in Olton?

Expect to budget between £1,300 and £7,500 depending on size and specification in Olton. Strip and replace a 20 m² rear extension roof in EPDM, with new deck and warm-roof insulation: typically £3,200–£4,600.

Which postcodes in Olton do you work in?

We cover B92 and the streets around them. If you're on the edge of Olton, neighbouring Acocks Green and Sheldon are covered too.

What guarantee comes with a flat roof?

The membrane and related materials are covered by the manufacturer's guarantee, and the terms for your roof are set out in your quote. Some manufacturers' guarantees depend on the roof being installed to their specification and inspected, which is worth asking about. Keep the paperwork with your building regulations certificate.

Does Solihull Council need to approve my flat roof?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Olton is provided by Solihull Council or a registered building control approver, and some work is self-certified by registered installers.
