Flat roofing in Harborne

Planning your flat roof in Harborne

Live in a conservation area or a listed building in Harborne? Check with Birmingham City Council before changing the outside of your home. Otherwise the main rules for your flat roof are Building Regulations, and we'll explain at the survey which certificates you'll receive.

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.
Because a warm-roof build-up raises the roof level, door thresholds and upstands need checking.

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.

Roof lights and outlets

Flat roof lanterns and flat glass roof lights can be fitted or replaced at the same time as a new roof. Outlets, gutters and edge trims are renewed so water runs away cleanly. Getting the fall right during the deck replacement is the best way to stop water pooling, which shortens a roof's life.

Flat roofing in Harborne: common questions

Which lasts longer, EPDM or GRP?

Both last far longer than old felt when properly laid, and the quality of the installation matters more than the material. EPDM is flexible and handles movement well, while GRP gives a hard, walkable, joint-free finish that suits complex shapes. Manufacturers' expected lifespans vary by product, and the guarantee terms for your roof are set out in your quote.

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.

Who approves flat roofing in Harborne?

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