Flat roofing in Selly Oak

What should you know before starting in Selly Oak?

This kind of work rarely needs planning permission, but it does have to comply with Building Regulations, and some parts must be certified by a registered installer or signed off by building control. In Selly Oak, building control is provided by Birmingham City Council or a registered building control approver (formerly an approved inspector).

GRP needs dry conditions to cure, so start dates can move with the forecast.
Replacing a flat roof's membrane over more than half the roof normally means upgrading its insulation.
Rotten decking is only found once the old roof is stripped, and any repair is agreed in writing first.

Which options suit homes in Selly Oak?

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.

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.

Before you book in Selly Oak

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.

How long does a flat roof replacement take?

A single garage roof usually takes one or two days, and an extension or dormer roof two to five days, depending on size, insulation and detailing. Flat roofing needs dry weather, especially GRP, so we may move a start date if heavy rain is forecast. The roof is kept covered overnight throughout.
