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.

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 Handsworth: 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.

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