Flat roofing contractors in Cheshire

We replace porch, bay and canopy roofs throughout Cheshire, re-covering them in EPDM, GRP or liquid-applied finishes. Each job includes a deck check, a proper wall flashing and drip trims that keep water off the frames. Guide prices for a typical porch roof are on this page, and the fixed price follows a free survey. We waterproof balconies and roof terraces across Cheshire, on houses, flats and mixed-use buildings. Each job starts with a survey to find where water is getting in, then a fixed written quote for a liquid, GRP, single-ply or mastic asphalt system with properly detailed door thresholds, outlets, wall upstands and balustrade fixings.

Which flat roofs are common in Cheshire?

Rain and wind decide how a flat roof is detailed. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Across Cheshire, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, lock-up garage blocks on estates and low-rise post-war blocks of flats. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Cheshire?

Extension and kitchen roofs

Rooflights fitted after the roof was built are a frequent source of trouble in Cheshire extensions. If the kerb was not formed properly or the membrane was simply sealed around the frame, leaks follow. Replacing the roof is the chance to rebuild every upstand to a proper standard.

Flat roof surveys and leak tracing

Landlords and managing agents in Cheshire often need a written record of a roof's condition, for budgeting, for leaseholders, or to show a problem has been looked at properly. A survey report gives them a clear basis for deciding when to repair and when to replace.

EPDM rubber roofing

Choose EPDM in Cheshire if you want a long service life without paying for a hard, walkable finish you do not need. With good detailing it typically lasts 25 years or more, and manufacturer material guarantees are available on many EPDM systems, registered for you where the system allows.

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

Which services do we offer in Cheshire?

Flat roofing in Cheshire: questions

Which roofing systems do you fit in Cheshire?

EPDM rubber, GRP fibreglass, torch-on felt, liquid-applied and single-ply, plus mastic asphalt repairs. The survey decides which suits your roof.

How much is a new flat roof in Cheshire?

A typical 18 m² EPDM garage roof is £1,500–£2,650 and a 20 m² insulated GRP extension roof is £2,850–£5,100, at North West guide rates including VAT.

Do you work on commercial roofs in Cheshire?

Yes: shops, offices, units and blocks of flats across Cheshire, with work planned around opening hours and residents.

Which council handles building control for a flat roof in Cheshire?

It depends on where the roof is: in Cheshire that's Warrington Borough Council, Cheshire West and Chester Council, Cheshire East Council and 1 other council. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. We confirm which applies at the survey.
