Flat roofing in Streetly

Planning your flat roof in Streetly

This kind of work rarely needs planning permission, but it does have to comply with Building Regulations, and some parts must be certified by a registered installer or signed off by building control. In Streetly, building control is provided by Walsall Council or a registered building control approver (formerly an approved inspector).

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.
Turning a flat roof into a pitched roof, or adding a roof terrace, usually needs planning permission.

Which option fits your home?

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.

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.

Your questions answered

How long does a flat roof replacement take?

A single garage roof usually takes one or two days, and an extension or dormer roof two to five days, depending on size, insulation and detailing. Flat roofing needs dry weather, especially GRP, so we may move a start date if heavy rain is forecast. The roof is kept covered overnight throughout.

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.

Who approves flat roofing in Streetly?
