Didsbury is one of the greenest parts of south Manchester. Tree-lined roads, big back gardens, Fletcher Moss and the Mersey valley right on the doorstep. It is a lovely place to live, but all that shade and damp air means roofs here stay wet long after the rain stops, and moss loves it.
A lot of homes in Didsbury Village and West Didsbury are Victorian and Edwardian, with slate or clay tile roofs, bays, dormers and valleys where moss and leaf litter collect. On these roofs the growth does real damage: it holds water against old slates and tiles, speeds up frost damage and blocks the valleys and gutters.
We clean every roof by the method that suits it. Hand scraping for older slate and clay, steam for modern concrete tiles, never a jet wash. Then a professional biocide goes over the whole roof to kill what is left and keep it off for two years.
Didsbury has some of the biggest and most complicated roofs in south Manchester. Late Victorian and Edwardian houses off Wilmslow Road and Palatine Road with slate, bays, dormers and tall chimneys, the semis that make up more than half of East Didsbury, and plenty of newer homes with concrete tiles.
Big old roofs have more valleys, hips and chimneys, and those are exactly the spots where moss and leaves sit. As roof cleaners we spend more time on those bits than anywhere else, because that is where water gets in if they are left.
Didsbury is really two wards, Didsbury East and Didsbury West, and between them the 2021 Census counted 29,792 people living in 13,658 households. The two halves feel quite different. East Didsbury is family-house country, with 57% of homes semi-detached, mostly in the streets around Parrs Wood, Fog Lane and Kingsway. West Didsbury is older and busier. About a third of homes there are purpose-built flats, and roughly one in five is in a big old house that has been split into flats.
A lot of that older housing is protected. Didsbury has four conservation areas: Didsbury St James, Albert Park, Old Broadway and Ballbrook. Didsbury St James was the first, designated in 1970, and it has the highest concentration of listed buildings anywhere in Manchester outside the city centre. Albert Park, in West Didsbury, is mostly late Victorian. If your house sits in one of them, keeping the original roof in good shape matters more than usual, which is one more reason we never put a jet wash near it.
Then there are the trees and the river. Fletcher Moss Botanical Garden alone covers 21 acres, and on top of that you have Didsbury Park, Marie Louise Gardens and Fog Lane Park, with the Mersey running along the southern edge. In our experience that mix of big old trees and river valley is why Didsbury roofs go green faster than most. Leaves land, rot and hold water, and the north-facing slopes hardly get a chance to dry out over winter.
We clean roofs all over the M20 postcode, from the terraces behind Didsbury Village and the Burton Road end of West Didsbury to the family homes near Parrs Wood High School, Didsbury High School on The Avenue, The Barlow RC High School and Beaver Road Primary. Nearly half the homes in West Didsbury are privately rented, so a good share of our work here is for landlords who want the roof and gutters sorted before a small problem turns into a damp complaint.
A bit of local history while we are at it. The name is thought to come from 'Dyddi's burg', and Didsbury only became part of Manchester in 1904. The RSPB traces its roots back to a group Emily Williamson started in 1889 at her house, The Croft, which is now part of the Fletcher Moss grounds. Not bad for a suburb better known for its bars on Wilmslow Road.
We check the tiles before anything else. Slate and older clay get hand scraped, concrete tiles get low-pressure steam. Nobody stands on your roof and there is no jet wash.
We work down the roof slope by slope, including the valleys, hips and ridges where moss sits thickest, and bag it as we go.
Everything that comes off the roof ends up in the gutters, so we empty them and check every downpipe runs clear.
A professional DDAC biocide is soft washed over every tile. It kills the spores that are left so the moss does not come back, and it is what our 2-year guarantee rests on.
Paths, drives and drains are swept and washed down, the bags go in the van, and you get before and after photos.
Roof moss removal in Didsbury mostly comes down to the trees. Leaf litter sits on the roof, rots, and gives moss something to grow in. Clear the moss without clearing the leaf mess and it is back in a year.
So we do both. Moss off, valleys and gutters cleared, then the biocide over the whole roof. That is what the 2-year no-moss guarantee is based on.
Why we will never put a jet wash on your tiles.

“My house is Victorian with a complicated roof structure.Peter managed to reach every nook and cranny to remove the moss which had badly accumulated on the North elevation of the building.The final result is impressive and I am sure will have added to the value of the house when we come to downsize next year. A difficult job well done.Thanks”
“I am so pleased with the work carried out by Hydro Cleanse to remove moss growth on the roof of our house. The house has a large extension to the side and rear. The steam cleaning is done without any need to stand on the roof. It is done from a scaffold tower and extendable pole. Both lads were hard working and competent throughout. I am sure more work will come their way by the results from this project. Highly Recommended 👌”
“Hydroclean did an amazing job other roof. Moss removal and years of grime cleaned away, then biocide treatment. We recently moved to the house, and this has made it look cared for! It actually looks like a new roof. Thank you very much.”
It depends on the size and pitch of the roof, the tiles and how heavy the moss is. Send your postcode and a couple of photos for a fixed quote, usually the same day, with no hidden fees.
Yes. Older slate roofs are cleaned by hand rather than steam, with a lot of care around brittle or slipped slates. If we spot damaged slates while we are up there, we photograph them and tell you before we leave.
All the time. Tree cover is the main reason Didsbury roofs grow moss so fast. We clear the moss, clear the gutters of leaf litter and treat the roof so it stays clean for longer.
Yes, and we do plenty of them in West Didsbury. We work entirely from outside, so nobody needs to be in. We just need the freeholder or managing agent to book it, and we send before and after photos for your records.
No. We only need access to the outside of the house. Most customers are at work while we clean, and we send photos when we finish.
Yes, once it has dried. We wet and cover delicate plants, apply it at low pressure onto the roof only, and ask you to keep pets inside while it goes on.
