Flat roof repairs in Chadderton, especially garages
Flat-roofed garages are everywhere in Chadderton, and many still have their original felt. That's why flat roof repairs in Chadderton are such a common job for us. We also replace flat roofs on rear extensions, porches and dormers.
We use three main systems: EPDM rubber, GRP fibreglass and modern torch-on felt. Each has strengths, and we recommend the one that suits your roof, not the one that's easiest for us.
Our quotes are free and come with no obligation. With over 20 years' experience, we'll tell you whether your flat roof can be repaired or really needs replacing.

Flat roofs around Chadderton
Chadderton's large post-war estates and inter-war semis often have flat-roofed garages, and many terraces have small flat roofs over rear kitchens. Plenty of these are covered in old felt that has cracked, blistered or been patched more than once. Ponding water and soft decking are common findings when we look.
We cover flat roofs across OL9, OL1 and M24, including Busk, Coalshaw Green, Middleton Junction, Hollinwood, Royton and Failsworth. From our Manchester base it's around 6 miles to Chadderton, which keeps call-outs straightforward.
How we replace a flat roof
We remove the old covering and check the deck. Soft or rotten boards are replaced, and where possible we improve the fall so water runs off. Then we lay the new system, fit edge trims and connect it to the gutter.
Most garage roofs are done in a day, larger extension roofs in one to two days, weather permitting. Call 0800 046 1159 for a free quote.
Chadderton flat roof questions
What's the best material for a garage roof?
For most standard garage roofs, EPDM rubber is an excellent choice: one sheet, few joints and quick to fit. GRP is great where there are more details or where you want a rigid finish. Modern torch-on felt is also a solid option. We'll recommend one after seeing the roof.
Can you replace a garage roof with asbestos sheeting?
Some older garages have asbestos cement roof sheets. These need handling by licensed specialists. If we suspect asbestos, we'll tell you and won't disturb it. Once it's been safely removed, we can fit a new roof.
My garage roof sags in the middle. Can that be fixed?
Usually, yes. Sagging normally means the deck or supporting joists have weakened. We replace damaged boards and, where needed, add supports or firring pieces to create a proper fall before laying the new roof.
Can you just patch my felt roof?
If the problem is a small split or blister and the rest is in good condition, a patch repair can work. If the felt is cracked all over or has been patched many times, replacing it is more reliable. We'll be honest about which applies.
Do I need planning permission for a new flat roof?
Usually not if you're replacing it like for like. If you plan to change its height, shape or add a roof light, check with Oldham Council. We'll explain what's changing so you know whether to ask.
Will a new flat roof stop my extension feeling cold?
A new covering alone won't add much insulation, but when we replace an extension roof we can discuss adding insulation as part of the build-up. That can make a noticeable difference. We'll explain the options and costs.
