This service has definitely increased in popularity recently as homeowners are recognising the problems a heavily moss infested roof can bring – Damaging tiles, blocking water runoff, clogging gutters and downpipes, and spilling all over nice clean patios. We also offer a pressure washing service to roofs where appropriate.
With a good pre-treatment plan in place, a gentle pressure clean can give instantly fantastic results without causing damage to the Roof. We assess each job before we begin and discuss with you the customer what your expectations and needs are.
We are fully insured, trained and experienced in this area. Please ask any questions about the process – we’re happy to explain!
Roof moss does cause problems
Not only the roof but the ground floors too. Birds sit on your roof routing around for food caught up in the moss and happily scatter the clumps down all over your patio.
Same-Day Response
A constant steady stream of thick green moss fills up your gutters and drain pipes. As we clear out gutters we see the next level of moss about to fall down in its place
Same-Day Response
How can a roof survey, a tile repair or pointing the ridge be carried out on something that cannot be seen due to heavy moss growth? Remove the moss then check the state of the roof
Same-Day Response
Moss holds water. The moss roots stick to the tile like superglue. When the moss freezes it expands. This slowly puts pressure on the tile until it gives way. So, moss needs moving.
Same-Day Response
But you may say –
And look – it’s all come back already.
Removing the moss is merely the preparation. Once the roof is cleared of thick moss clumps, soil and detritus, we can then apply the professional Roof cleaning product http://www.algoclear.com/ – Created by specialist roof cleaners in Leeds, West Yorkshire.
With our professional-grade equipment, we saturate the Roof tiles to kill off the spores of biological growth which have infested your house. This is a powerful biocide developed to kill unwanted organisms and biofilm – but it can do its job without damaging or even affecting the substrate upon which it is sprayed.
Then the process is simple. Allow the weather to do the rest. The remains on the roof will dry out, then rinse away with showers and wind.
There’s more than one way to clean a roof, and yours won’t suit all of them. Which method you get depends on the tiles and how much dirt and moss has taken hold up there. We’ll tell you which one before we start.
Every roof clean starts here
Moss comes off in two layers. The clumps on top lift away easily enough, but underneath them is a matted root stuck to the tile, and no machine shifts that without taking tile with it.
So we do it by hand, ridge down to gutter, one section at a time. It’s slow work and we won’t pretend otherwise. You dont have to worry about your garden, it gets sheeted before we start.
Fast results, on the right roof
Nothing changes the look of a roof as quickly as pressure, and on a sound roof with good mortar it’s the best option going.
On an older roof it does damage you can’t see from the ground. Tiles lose their surface, mortar gets driven out of the ridge, and water finds its way under the laps. That’s why we test a small section first and let you look at the difference before we commit to the whole roof. If your tiles won’t take it, we’ll say so and use something gentler.
The one we use most
We treat the whole roof with a professional biocide and then we leave it alone. It soaks into the tile and kills the moss, algae and lichen at the root, along with the spores that would have kicked the whole thing off again next spring.
Nothing looks different straight away. Give it a few weeks of rain and wind and the dead growth dries off and washes away by itself. What’s left underneath is usually closer to the roof’s original colour than people expect.
Mostly roofs don’t actually get dirty. They get regularly washed with rainwater, therefore, dirt-particles usually doesn’t get chance to settle-up there. You may be wondering – why my roof looks dirty?
The truth – it’s mostly organic growth. These porous tiles hold onto the damp, creating perfect environment for algae, moulds, mildew, lichens, and moss to slowly form and quickly thrive right on top of your house!
Don’t panic this is not a disaster. The moss is not usually harmful. We have on occasion seen where moss has excreted an acid which eats away at the tile but this is rare (there are thousands of different types of moss).
Every job runs the same way. From the first free survey to the final sweep up. Here is exactly what happens, and roughly how long each part takes.
We look at the roof from the ground first, then up on it if we need to. You get a written price the same day, and it is the price you pay.
Free survey, no obligation
Garden furniture moved, plants covered, gutters bagged off, path sheeted. Dust off a dry roof travels further than people think once the scraping starts, and a clean roof is no use if your car and windows are grey afterwards. Last thing we do on site is a walk round to check we left nothing behind.
Your property protected first
Cracked tiles, slipped slates, mortar gone from the ridge. We photograph anything like that, show you on the screen, and price the repair before we touch it. No repair gets done without you saying yes to it.
Photos of anything we find
By the time we pack up, your roof tile is showing through again and there is nothing on the drive but your own car. Everything that came off the roof leaves in bags with us, including the bits that landed on the lawn.
All waste removed from site

“Our roof cleaning of moss was carried out to a high standard in every aspect from the initial inspection to the final finished results. Would highly recommend this family run very professional business”
Elaine Walker

“Great experience with PureGem who cleaned our roof today. A family company who did a fantastic job. Luke and his sons were friendly and polite (even helped me lift a heavy parcel into the house which arrived whilst they were here!). Luke turned up when he said he would for both the quote and the work. Our 35 year old roof looks nearly as good as new. We’d recommend to friends & family.”

“Luke and his team did a great job cleaning our roof and gutters on our house. They completed the job quickly and professionally while having to work in terrible weather without complaint. We will definitely use them again. Highly recommended!”
David Elliott

“Luke and his team transformed a large, neglected, moss covered roof to one which looked like we’d had the whole roof replaced. Excellent job, completed to the highest standard, would recommend to anyone.”

Key coverage areas:
Four things decide it:
A bungalow in Otley and a three-storey terrace in Leeds are not the same job, and anyone giving you a flat price without asking about access has not seen enough roofs.
Ring us or send a photo and you will have a fixed figure the same day. No call-out fee, no charge for the visit, and nothing added on afterwards.
Nothing bad. The treatment bonds to the tile and keeps working wet or dry, and a bit of rain helps by washing away what is already dead.
Most semi-detached and detached roofs are done inside a day, sometimes half if the moss is light. A big roof, a steep pitch or one that needs scaffold can run into a second visit, and we will tell you which you are getting before we start.
Shade, mostly. The side that never sees sun stays damp longest, so a roof facing north or sitting under a line of trees collects growth years before the one opposite. Porous concrete tiles hold more water than slate, valleys and gullies trap leaves, and even a new extension or a tall fence can change how much light or wind reaches a roof. Nothing has gone wrong. It just dries out slower than the roof next door.
Send a few photos or give us a ring and we’ll work out what your roof needs. Most houses can be priced from a picture, and the figure comes back in writing, usually inside a day. No visit needed unless the roof is big or awkward to get at.
