Flat roofing in Dudley

Planning your flat roof in Dudley

Work like this in Dudley rarely needs planning permission, but parts of the job must meet Building Regulations — certified electrical work, ventilation or energy-efficiency standards, for example. Your quote shows how each part is signed off. If planning does come into it, say for a listed building, Dudley Council is the authority.

The target U-value for a renovated roof is 0.16 W/m²K, where that's practical.
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.

Choices to weigh up in Dudley

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.

Torch-on felt

Modern reinforced bitumen membranes laid in two or three layers, bonded with heat. They're tougher and longer-lasting than old felt and suit roofs with lots of upstands and pipes. Felt is often the cheapest option, but it takes longer to lay and naked flames on site need extra fire precautions.

Questions about flat roofing in Dudley

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.

Do you cover the whole of Dudley?

Yes — we cover Dudley from our West Bromwich base, including Sandwell, Wolverhampton and Walsall. Call 0800 088 6248 or send the form on this page to book a free survey.

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.

Will I need permission from the council in Dudley?

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