Flat roofing in Sutton Coldfield

Planning your flat roof in Sutton Coldfield

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 Sutton Coldfield, building control is provided by Birmingham City Council or a registered building control approver (formerly an approved inspector).

Replacing a flat roof's membrane over more than half the roof normally means upgrading its insulation.
GRP needs dry conditions to cure, so start dates can move with the forecast.
Getting the fall right stops water pooling, which shortens the life of any membrane.

Which option fits your home?

EPDM rubber roof

A single sheet of synthetic rubber bonded to the deck, often in one piece with no joints on smaller roofs. EPDM handles temperature changes well, is quick to lay and needs little maintenance. It's a good all-round choice for garages and extensions, though it has a plain black finish and needs care around complex details.

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.

How should I prepare for a new flat roof?

Clear the garage or room below of valuables in case of dust from the deck, and move cars if the skip or materials need the drive. Let us know about any satellite dishes, vents or pipes on the roof. If the roof is next to a neighbour's wall or boundary, a quick word with them about access helps.
