Flat roofing in Marston Green: approvals and local details
Live in a conservation area or a listed building in Marston Green? 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.
- Turning a flat roof into a pitched roof, or adding a roof terrace, usually needs planning permission.
- Because a warm-roof build-up raises the roof level, door thresholds and upstands need checking.
- 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.

Before you book in Marston Green
Why does my flat roof leak when the surface looks fine?
Most leaks start at the edges, joints, outlets or where the roof meets a wall, not in the open middle of the roof. Water can also travel along the deck before it shows on the ceiling, so the stain may be a long way from the actual entry point. We check these details at survey before suggesting a repair or replacement.

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.
Who approves flat roofing in Marston Green?
