Flat roofing in Erdington

Because a warm-roof build-up raises the roof level, door thresholds and upstands need checking.
GRP needs dry conditions to cure, so start dates can move with the forecast.
Turning a flat roof into a pitched roof, or adding a roof terrace, usually needs planning permission.

Which options suit homes in Erdington?

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.

Flat roofing in Erdington: common questions

What guarantee comes with a flat roof?

The membrane and related materials are covered by the manufacturer's guarantee, and the terms for your roof are set out in your quote. Some manufacturers' guarantees depend on the roof being installed to their specification and inspected, which is worth asking about. Keep the paperwork with your building regulations certificate.

Which postcodes in Erdington do you work in?

We cover B24 and the streets around them. If you're on the edge of Erdington, neighbouring Castle Vale and Walmley are covered too.

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 Birmingham 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 Erdington is provided by Birmingham City Council or a registered building control approver, and some work is self-certified by registered installers.
