Flat roofing in Bartley Green: approvals and local details
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 Bartley Green, building control is provided by Birmingham City Council or a registered building control approver (formerly an approved inspector).
- Turning a flat roof into a pitched roof, or adding a roof terrace, usually needs planning permission.
- Getting the fall right stops water pooling, which shortens the life of any membrane.
- GRP needs dry conditions to cure, so start dates can move with the forecast.

Choices to weigh up in Bartley Green
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.
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 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.
Which postcodes in Bartley Green do you work in?
We cover B32 and the streets around them. If you're on the edge of Bartley Green, neighbouring Northfield and Harborne are covered too.
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 Bartley Green?
You won't usually need planning permission, but the work must meet Building Regulations. Building control in Bartley Green is provided by Birmingham City Council or a registered building control approver, and some work is self-certified by registered installers.
