Choices to weigh up in Hall Green
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.

Do you cover Hall Green?

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