Flat roofing in Coventry

Before your flat roof in Coventry

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

Most flat roof leaks start at edges, joints, outlets or wall abutments.
Rotten decking is only found once the old roof is stripped, and any repair is agreed in writing first.
The target U-value for a renovated roof is 0.16 W/m²K, where that's practical.

Which option fits your home?

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.

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.

What does your flat roof cost in Coventry?

Before you book in Coventry

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.

Do you cover the whole of Coventry?

Yes — we cover Coventry from our West Bromwich base, including Warwickshire, Solihull and Birmingham. Call 0800 088 6248 or send the form on this page to book a free survey.

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.

Will I need permission from the council in Coventry?

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