Flat roofing in Sedgley: approvals and local details
Live in a conservation area or a listed building in Sedgley? Check with Dudley 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.
- Because a warm-roof build-up raises the roof level, door thresholds and upstands need checking.
- Rotten decking is only found once the old roof is stripped, and any repair is agreed in writing first.
- Getting the fall right stops water pooling, which shortens the life of any membrane.

Options to consider in Sedgley
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.
GRP fibreglass roof
Glass-reinforced plastic laid as a liquid resin and matting over a board deck, which cures into a hard, joint-free, walkable surface. GRP works well on roofs with awkward shapes, roof lights and balconies, and comes in grey and other colours. It must be laid in dry conditions and needs a stable deck.

Your questions answered
How should I prepare for a new flat roof?
Clear the garage or room below of valuables in case of dust from the deck, and move cars if the skip or materials need the drive. Let us know about any satellite dishes, vents or pipes on the roof. If the roof is next to a neighbour's wall or boundary, a quick word with them about access helps.
Do you cover Sedgley?
Yes. Sedgley (DY3) is about 6 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.
How much does a new flat roof cost?
In the West Midlands, re-covering a single garage roof usually costs around £1,300–£2,600, and a 20–30 m² extension roof around £2,400–£5,200, depending on the membrane, deck repairs and insulation. Dormer roofs cost more because of access. Your quote names the membrane and lists deck work and insulation separately.
Will I need permission from the council in Sedgley?
You won't usually need planning permission, but the work must meet Building Regulations. Building control in Sedgley is provided by Dudley Council or a registered building control approver, and some work is self-certified by registered installers.
