Flat Roofing in Orrell
Garage, extension and dormer roofs in EPDM rubber, GRP fibreglass or felt, laid to falls so water leaves instead of ponding. West of Wigan, a short drive from us.
Flat Roofing for Homes in Orrell
A lot of the flat roofing in Orrell is on the single-storey rear extensions, dormers and garages that came with the semis and the estate housing. Most were laid in felt years back, and once that felt blisters, splits or starts holding a pool of water, damp works its way into the room or the garage below. We strip it off and re-cover in EPDM rubber or GRP fibreglass, both of which outlast the old felt by a wide margin and cope far better with a wet, windy hillside.
We cover Orrell and the surrounding area: Orrell Post, Moor Road, Sandy Lane, Lamberhead Green, Winstanley and beyond (WN5).

What’s Included
The higher western streets rising toward Billinge Hill take the wind-driven rain full on, and that is exactly the weather that finds a weak lap or a poorly detailed edge on a flat roof. We set the falls so water runs off instead of sitting in a low spot, and we detail the upstands where the flat roof meets a wall or the main pitch in lead, because that join is where most flat roof leaks in Orrell begin. The result is a flat roof that stays watertight through a real Billinge blow, not one that looks fine until the first driving rain.
- 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 Orrell, FAQs
For most Orrell extensions, dormers and garages we would fit EPDM rubber or GRP fibreglass. Both are a long step up from the old felt, and which one suits depends on the size, the shape and the detailing, which we go through with you on site.
On the exposed higher ground a patch on old felt rarely lasts, because the wind-driven rain finds the next weak spot. A full recover in rubber or fibreglass stops the leak for the long term and costs far less than the damage a leaking roof does to what is stored underneath.
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.
Old style felt was ten to fifteen years if you were lucky. A well fitted EPDM or GRP roof is a different class: the materials themselves are rated for decades. The weak point is always the workmanship at edges and outlets, which is exactly where we take the most care.
Standing water, called ponding, ages any flat roof faster: it strains the membrane, freezes in winter and finds any weak seam. Sometimes the fix is as simple as correcting the falls with firring or a tapered board when the roof is recovered. If your roof ponds, it is worth a look before it starts leaking.
