Flat roof repairs and replacements in Chorlton
Chorlton has a lot of flat roofs hiding behind its period frontages: over kitchen extensions, on top of dormer loft conversions, above bay windows and on garages. We repair and replace flat roofs in Chorlton using EPDM rubber, GRP fibreglass and modern torch-on felt.
The usual trouble spots are where the flat roof meets the main house, around rooflights, and at the edges. Water that sits on a sagging deck is another common issue, and a sign the roof may need more than a patch.
Our quotes are free with no obligation. With over 20 years' experience, we'll tell you plainly whether a repair or replacement makes more sense.

Flat roofs on Chorlton homes
With so many loft conversions and kitchen extensions on Chorlton's Edwardian and Victorian terraces and semis, flat roofs are part of everyday roofing here. Older extensions often still have their original felt, while newer ones may have rooflights that need checking. Dormer roofs face more weather than people expect and are often the first to need work.
We cover flat roofs across M21, including Chorlton Green, Chorlton Park, Whalley Range, Stretford, Didsbury and Firswood. From our Manchester base it's around 3 miles to Chorlton, which keeps call-outs straightforward.
How we replace a flat roof
We strip the old covering, check the deck and replace any soft boards. Where possible, we improve the fall so water drains away rather than ponding. Then we lay the new system, form upstands at walls and rooflights, fit trims and connect to the gutter.
Most extension and dormer roofs are completed in one to two days, weather permitting. Call 0800 046 1159 to arrange a free quote.
Flat roof FAQs for Chorlton
My rooflight leaks. Is it the window or the roof?
It can be either. Leaks often come from the upstand around the rooflight rather than the glazing itself. We check the seals, the upstand and the roof covering around it to find the source, then repair whichever part has failed.
Is GRP or EPDM better for a dormer?
Both work well. GRP gives a hard, seamless finish that's good where there are upstands and details. EPDM is flexible and quick to fit. We'll recommend the right one based on the dormer's size, shape and how it meets the main roof.
Do I need planning for a new flat roof on my extension?
Replacing an existing flat roof like for like usually doesn't. If you're changing its height, adding a lantern, or you're in a conservation area, check with Manchester City Council first.
Can you add insulation when replacing a flat roof?
Yes. Replacing the roof is a good time to add insulation, which can make an extension noticeably warmer. We'll explain how it affects the roof height and edges and include it in the quote if you'd like.
Why does water pond on my extension roof?
Ponding usually means the deck has sagged or the roof wasn't built with enough fall. Water sitting for days stresses the covering. When we replace the roof, we can add firrings to create a better fall.
Can you repair a flat roof bay window?
Yes. Many Victorian and Edwardian bays have small flat or lead roofs that leak at the joint with the house. We repair or renew them and make sure the flashing to the wall is sound.
