Your trusted, local experts delivering quality workmanship and lasting protection for your home across Winsford and the wider Cheshire West region.
A typical garage or extension flat roof takes 1 to 3 working days. Full strip and dispose of the existing felt or failed membrane, replace any rotten or saturated 18mm OSB3 deck where required, install rigid PIR insulation above the deck for a warm roof build (or between joists for a cold roof refresh), fit kerb trims and drip edges, lay your chosen membrane to manufacturer specification, dress upstands at every abutment, fit Code 4 lead where the flat meets a pitched roof or wall, check and clear the gutter and downpipe run, full site clear-down with skip and waste removal. Written fixed-price quote with no deposit.
EPDM rubber single-ply is a synthetic membrane usually laid as a single piece up to typical garage size with no seams, ideal for residential garages, extensions and dormers, 25 to 30 year manufacturer guarantee, the most flexible option in Cheshire's freeze-thaw cycles. GRP fibreglass is a cold-applied resin laminate with built-up matting for a rigid, walkable surface, ideal for balconies, dormers and any flat that takes foot traffic, 25-year manufacturer guarantee. Liquid polyurethane systems are cold-applied directly over a sound substrate, ideal for refurbishment where a full strip is not viable, typically 20 to 25 year guarantee. We talk you through which suits your roof at the survey.
Most older flat roofs in Cheshire are cold roofs, where the insulation sits between the joists and the structural timber is exposed to outside temperature. They lose heat, suffer condensation in the void, and shorten the deck's lifespan. Warm roof construction puts rigid PIR insulation above the deck under the membrane, keeping the entire structure inside the warm envelope of the house. Heat loss drops, condensation stops, the deck lasts longer, and the room below is a usable temperature year-round. We recommend the warm roof build on every kitchen extension or habitable space and price both options at quote so you can compare.
If the existing roof is more than 80 percent sound and the deck is dry underneath, a liquid polyurethane overlay seals the leaks and buys you another 20 to 25 years for a fraction of the strip-and-replace price. If the deck is rotten, the falls are wrong (causing ponding), or the felt is blistered across most of the area, a full replacement is the only honest answer. We open a small inspection point on the survey to check the deck condition before quoting, so the recommendation is based on what is actually under the felt, not just what is on top.

Flat roofing across these key Cheshire and North West locations.
EPDM rubber is the most popular choice for residential garages and small extensions because it lays as one piece with no seams and handles British freeze-thaw cycles without cracking. GRP fibreglass is the better call where the roof needs to be walked on (balconies, dormer flats, terraces). Liquid polyurethane is the right call for refurbishment where the existing roof is mostly sound but leaking at joints.
Often a repair is enough, especially if the leak is at a flashing or upstand and the rest of the membrane is sound. We lift a section to check the deck before recommending. If the deck is wet or rotten, replacement is the only call that lasts.
EPDM 25 to 30 years on a typical residential install, GRP 25 years walkable, liquid systems 20 to 25 years on a sound substrate. Manufacturer guarantees back the membrane, our workmanship guarantee covers the install.
Yes, on a full replacement we can convert a cold roof to a warm roof by laying PIR insulation above the deck before the membrane goes on. Adds about 100mm to the roof height but transforms the room below for both temperature and condensation.
Yes, garage flats are one of the most common jobs we run, EPDM is usually the right material, typical 1 to 2 day turnaround on a single garage.
