Flat roofs that
stay bone dry.

Extensions, garages, dormers and bays. High-performance flat roof systems, including warm roof build-ups that keep the heat in and the condensation out. Written guarantee on every new roof.

Flat roofing

The build-up matters more than the covering.

Most flat roofs do not fail because the covering wore out. They fail because the build-up underneath was wrong: no ventilation, no insulation, moist air condensing on cold timbers until the deck rots from below.

That is why we talk about warm roofs. Insulation goes above the deck, the whole structure stays at room temperature, and condensation never gets a foothold. It is the difference between a roof that lasts 10 years and one that lasts 40, and it is standard practice on our new flat roofs.

Perfect for

  • Extension roofs, kitchen and rear extensions where a leak ruins the best room in the house
  • Warm roof upgrades, adding insulation above the deck while re-covering
  • Garage and outbuilding roofs, replaced without fuss at sensible prices
  • Dormers and bay tops, weathered in properly where they meet the main roof
  • Roof lanterns and skylights, built in and sealed as part of the new roof, not an afterthought
The job, step by step

How a flat roof goes on.

01

Survey & spec

We measure up, check the existing deck and falls, and spec the right system for the roof: felt, warm roof build-up, or GRP if the job calls for it.

02

Strip & deck

Old coverings stripped, rotten decking replaced, and falls corrected so water actually runs to the outlets instead of ponding.

03

Insulation & membrane

Warm roof insulation laid above the deck where specified, then the waterproof layer fitted to manufacturer spec.

04

Edges & handover

Trims, upstands and flashings detailed properly, site cleared, and a written guarantee handed over on every new roof.

Felt or fibreglass? We will spec what suits the roof, not the sales pitch.

Both systems have their place, and we fit both. You get a straight recommendation with the reasons why, and a free written quote either way. If you want to compare, have a look at our GRP fibreglass page too.
