Flat roof replacement and flat roof repairs in Denton
If you live on one of Denton's post-war streets, there's a good chance your garage has a flat roof, and a fair chance it's leaking. Our flat roof service in Denton covers garages, rear extensions, porches and dormers, with repairs where the roof is still sound and full replacement where it isn't.
We work with EPDM rubber, GRP fibreglass and torch-on felt. Each has a different price and finish, and we'll recommend whichever makes most sense for your roof.

Layered felt system, a reliable and economical choice for many garage roofs.
Repairs and patching
Splits, blisters and failed edge trims fixed when the deck below is still sound.
Flat-roofed garages and extensions in Denton
Denton's inter-war and post-war semis often came with a flat-roofed garage, and many of those roofs are now coming up for replacement. Older garage roofs may be felt laid on chipboard, which sags and rots once water gets in, or old sheeting that needs careful handling. We also replace flat roofs on rear kitchen extensions and porches, which are just as common on the modern estates.
We work across M34, including Haughton Green, Dane Bank and Audenshaw, and in nearby Hyde and Reddish. From our Manchester base it's around 5 miles to Denton, which keeps call-outs straightforward.
Signs your flat roof needs replacing
Water standing on the roof long after rain, bubbles or cracks in the surface, a soft or bouncy deck, and damp on the ceiling below are the main warning signs. If it's been patched more than once, it's probably time to replace it.
Call 0800 046 1159 and we'll inspect the roof, check the deck, and give you a written quote with the options explained.
Flat roof questions from Denton
What's the best roof for my garage?
For most Denton garages, EPDM rubber or torch-on felt both work well. EPDM goes down as one sheet with few joints; felt is often the more economical choice. GRP suits roofs that get walked on. We'll recommend one after looking at the size and condition of the garage.
My garage roof is old corrugated sheeting. Can you replace it?
Yes. Some older garage roofs are corrugated sheets, and older ones may contain asbestos. If we suspect that, we'll tell you so it can be tested and removed safely before we fit a new roof. We can then build a new deck and fit a modern flat roof covering.
Can you fix a leak where my extension meets the house?
Yes. That join is one of the most common leak points. It usually needs a properly fitted upstand and lead or membrane flashing into the wall. We'll check how it was done originally and put it right so water can't track behind it.
Is it worth repairing a felt flat roof?
If the problem is a small split or a single blister and the rest of the felt is sound, yes. If the felt is cracked all over or the deck is soft, a repair will only last a short time. We'll tell you honestly which applies.
Can you add a better fall to stop water pooling?
Yes. When we replace a flat roof, we can fit firring strips to create a proper fall, so water runs off to the gutter instead of sitting on the roof. It's one of the simplest ways to make a new flat roof last longer.
Do you replace porch and canopy roofs?
Yes. Small porch and bay roofs are easy to forget, but they leak just like bigger ones. We can renew them in EPDM, GRP or felt, or with lead, depending on the shape and how they meet the house.
