GRP needs dry conditions to cure, so start dates can move with the forecast.

Choices to weigh up in West Bromwich

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.

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.

How much does a new flat roof cost?

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 West Bromwich?

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