Flat roofing in Allesley: 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 Allesley, building control is provided by Coventry City Council or a registered building control approver (formerly an approved inspector).
- Getting the fall right stops water pooling, which shortens the life of any membrane.

Which option fits your home?
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.

Questions about flat roofing in Allesley
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.
Do you cover Allesley?

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.
Does Coventry City Council need to approve my flat roof?
You won't usually need planning permission, but the work must meet Building Regulations. Building control in Allesley is provided by Coventry City Council or a registered building control approver, and some work is self-certified by registered installers.
