Flat roofing in Smethwick

Before your flat roof in Smethwick

Work like this in Smethwick rarely needs planning permission, but parts of the job must meet Building Regulations — certified electrical work, ventilation or energy-efficiency standards, for example. Your quote shows how each part is signed off. If planning does come into it, say for a listed building, Sandwell Council is the authority.

Rotten decking is only found once the old roof is stripped, and any repair is agreed in writing first.
Getting the fall right stops water pooling, which shortens the life of any membrane.
Most flat roof leaks start at edges, joints, outlets or wall abutments.

Which option fits your home?

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.

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.

Flat roofing in Smethwick: 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.
