Flat Roofing for Homes in Bolton
A lot of the flat roofing on the near side of Bolton is on the rear back-additions and outriggers that these Victorian terraces were built with, the two-storey rear wing off the back of the house, plus the low lean-to roofs over sculleries, extensions and garages. Nearly all of them started life in felt, and once felt blisters, splits along the seams or holds a pool where the fall has flattened, it lets damp straight into the room beneath. We strip the perished felt off and re-cover in EPDM rubber or GRP fibreglass, both of which see off the Bolton weather for decades where felt gave you a few years.
We cover Bolton and the surrounding area: Deane, Daubhill, Morris Green, Over Hulton, Middle Hulton and beyond (BL3, BL5).

What’s Included
The weak point on these back-addition roofs is always the join, where the flat roof tucks against the tall rear wall of the terrace or under the main slope, and around Daubhill and Morris Green that upstand is where we find most of the leaks. We dress fresh lead into those abutments rather than trusting a smear of mastic, and lay the new roof to a real fall so the water runs off to the outlet and away from the brick, not into a hollow that fills again the next time the rain sets in.

How It Works
Flat Roofing in Bolton, FAQs
For most of the back-additions and lean-to roofs around Deane and Daubhill we would fit EPDM rubber or GRP fibreglass. Both are a long step up from the old felt, and which one suits comes down to the size, the shape and how it meets the wall behind, which we go through on site.
Usually yes. Recovering a garage or a back-addition flat roof is a straightforward job that stops the leak for good, and it costs far less than putting right the damage a leaking roof does to the ceiling and floor below.
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.
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.
If the covering is basically sound and the problem is local, yes, a patch or a new outlet detail can buy years. If the felt is blistered and cracked across the whole roof, patching is money down the drain and we will say so. You get the right option, priced.
