Flat Roofing for Homes in Horwich
A good part of the flat roofing we do in Horwich is on the rear extensions, dormers, garages and porches added to the houses over the years, and up here they take a real soaking. The rain that comes off Winter Hill and the moors is heavier and more frequent than it is lower down, so a flat roof that does not drain ends up holding water for days, and once the old felt blisters or splits the damp is straight into the room below. We strip it back and re-cover in EPDM rubber or GRP fibreglass, both of which shrug off that kind of weather far better than felt ever did.
We cover Horwich and the surrounding area: Middlebrook, Lever Park, Chorley New Road, Church Street, Wallsuches and beyond (BL6).

What’s Included
The junction where a flat roof meets the house is where it tends to fail first, and on the stone houses in Horwich that means the upstand against a gritstone wall or the abutment under a steep main pitch. We dress those details in lead rather than trusting a run of sealant, and lay the new roof to falls so the water drains away to the outlet instead of pooling. What you get is a flat roof that stays dry right through a long wet spell off the moors, not one that looks sound until the first low corner fills.
- EPDM rubber, one-piece membrane with no seams
- GRP fibreglass with a hard-wearing gel top coat
- High performance felt where it suits the job
- Falls corrected so water drains instead of ponding
- Rotten decking cut out and replaced
- Edge trims, outlets and upstands fitted to spec
How It Works
Flat Roofing in Horwich, FAQs
For most extensions and dormers up here we would fit EPDM rubber or GRP fibreglass. Both are a big step up from felt and cope with the volume of rain that comes off the moors, and which one suits comes down to the size, shape and detailing, which we go through on site.
It is, and it is common up here because of how much rain we get. Standing water finds any weak spot in time. We lay the new roof to falls so it drains to the outlet, so the water is gone rather than sitting there working at the covering.
Both are excellent when fitted right, so it comes down to the roof. EPDM suits larger, simpler roofs because it goes down in one continuous sheet and copes with a bit of movement. GRP gives a hard, walkable finish and crisp edges, which suits smaller roofs, balconies and roofs with lots of detail. We quote whichever suits yours, or both so you can compare.
All the time. Single and double garage roofs are one of our most common flat roofing jobs, usually stripped, decked and finished in EPDM in a day or two.
