Roof Cleaning Liverpool, moss removed by hand with no pressure washing

Our roof cleaning starts from £200 for a small roof, from £300 for a medium roof and from £400 for a large one. Every price includes a full manual scrape to remove the bulk of the moss, a soft-wash biocide treatment to kill the spores, and clearing the moss debris out of your gutters afterwards.

The exact figure depends on the size of the roof, the pitch, the number of storeys and how thick the moss has become. A steep pitch, a hard-to-reach roof or heavy, long-established growth can push the price towards the top of each range. We are always upfront about that before we start, and photos sent on WhatsApp get you 10% off your quote.

We never use high-pressure jetting on a roof, because it can force water under the tiles and cause leaks. If your gutters need a proper deep clean and downpipe flush on top of the moss debris, our gutter cleaning service can be added on the same visit.

• Manual scraping removes the bulk of the moss
• Soft-wash biocide treatment kills spores at the root
• No high pressure to avoid water ingress
• Fully insured for working at height

Usually a same-day quote. Send us a photo of your roof showing the moss growth and we can usually give you a price within about 10 minutes. Photos of each roof slope help, especially the back, because the north-facing side is often far worse than the front. A wider shot showing the height of the house helps us plan safe access too.

Roof moss is not just an eyesore. It can lift tiles and cause damp problems inside the home, so once you have spotted it you will want it sorted. Being local to Liverpool, Wirral and Sefton means we can often pop out to take a look if the photos are not clear enough, and we are open seven days a week, 7am to 7pm.

If you would rather speak to us or fill in a form, head to our contact page. Tell us roughly when the roof was last treated, if ever, and we will give you a price and honest advice on whether it needs doing now.

It protects your roof and the rooms underneath it. Moss acts like a sponge, soaking up rainwater and holding it against your tiles. In winter that water can freeze and expand, which can crack tiles and lift them out of place. Those gaps let water get under the tiles and into the roof space, leading to damp ceilings, rotten timbers and expensive repairs.

Thick moss also creeps under the edges of tiles and around ridge lines, where it is hard to spot from the ground. When it washes loose in heavy rain it ends up in your gutters, causing blockages and overflow that soak your walls. Professional removal followed by a biocide treatment breaks that cycle and keeps the roof shedding water the way it should.

Roof run-off is also one of the main reasons white fascias and soffits go green. Once the roof is clear, our fascia cleaning can bring the roofline back to a crisp white finish.

• Prevents tiles cracking in winter frost
• Stops damp and rot in your roof timbers
• Reduces the risk of blocked gutters
• Protects your home’s insulation

Soft washing is the safe way to treat a roof. Pressure washing forces water at high speed under the tiles, which can lift them and damage the felt underneath. That often leads to leaks inside the home. Soft washing uses a low-pressure spray to apply biocide that kills moss, algae and lichen at the root, without driving water where it should not go.

Our method combines both sides of the job properly. We scrape the bulk of the moss off by hand first, then soft-wash the biocide across the tiles. Any small traces left behind dry out and gradually weather away over the following weeks. We never point a pressure washer at a roof, and we take care with run-off around plants, ponds and pets.

The same gentle thinking runs through our UPVC cleaning on conservatory roofs, window frames and doors, where too much pressure can damage seals and let water in.

• Soft washing is gentle on tiles and felt
• No risk of water ingress or leaks
• Biocide kills moss at the root for long-term results
• Safe for surrounding gardens and wildlife

Usually 3 to 5 years. The biocide treatment kills the existing moss and algae and leaves a residual layer that slows new spores from taking hold. Over time, sun and rain break the treatment down, so it does not last forever, but most roofs stay clear for several years after a proper clean.

How long it lasts on your house depends on shade, trees and which way the slopes face. A sunny, open roof may go five years or more, while a roof under big trees or facing north may need attention a bit sooner. Many customers book a light maintenance treatment around the three-year mark to keep on top of it before the moss can build up again.

Mature, leafy suburbs like Gateacre tend to see regrowth sooner because of the extra shade and leaf fall. You will also notice your gutters stay clear of moss debris for much longer after a treatment.

• Long-lasting protection for 3 to 5 years
• Prevents new moss spores from germinating
• Cost-effective maintenance cycle
• Keeps gutters clear of moss debris

Yes, our method is safe for all the common roof types we see across Merseyside. Concrete interlocking tiles on post-war and modern homes tend to grow thick cushions of moss because of their rough surface. Clay tiles and natural slate are smoother, but still pick up moss in the joints, along the ridge and around chimneys.

Each type is handled with care. Slate and older clay tiles can be brittle, so we scrape gently and avoid putting weight where it is not needed. On concrete tiles we take time to work the moss out of the deep grooves before applying the biocide. Before we start we check for loose or broken tiles and point out anything we find.

We clean everything from Victorian slate roofs in Birkdale to larger detached homes with concrete tiles in West Kirby, so whatever your roof is made of, we will choose the right approach for it.

Often it does. If you keep finding green clumps in your gutters or scattered on the path below, they are almost certainly coming off the roof. Birds pulling at the moss for nesting material and heavy rain washing it loose both send it straight down into the gutters, where it soaks up water and blocks the outlets.

Clearing the gutters fixes the immediate overflow, but the problem will keep coming back until the roof itself is treated. That is why every roof clean we do includes clearing the moss debris out of the gutters afterwards, so you are not left with blocked runs from the job.

If you are trying to decide what to tackle first before the bad weather sets in, our guide on why gutter cleaning before winter matters explains why clear gutters matter so much in the colder months, and how roof moss plays its part in that.

Yes, as long as the weather is safe to work in. Moss actually grows strongly through the cooler, wetter months, so autumn and winter are a sensible time to deal with it before frost gets into the tiles. We avoid days with ice, strong winds or heavy rain, because working at height has to be safe and the biocide needs a dry spell to do its job.

We keep an eye on the forecast and book roof work into the drier windows, which usually means we can still get to you fairly quickly. We are open seven days a week, 7am to 7pm, which gives us plenty of flexibility to fit roof work around the weather, including weekends.

If you are wondering whether to book now or wait until spring, our guide on whether winter is a good time for exterior cleaning covers the pros and cons. For most roofs, dealing with the moss sooner rather than later is the safer choice.

There will be some moss coming down, but we clear it up before we leave. As we scrape the roof, clumps fall into the gutters and onto paths, drives and flower beds below. We sweep and bag that up at the end, clear the gutters of moss debris and leave the outside of your house tidy.

You do not usually need to be at home, as long as we have safe access round the outside of the property and somewhere to put our ladders. Please move cars off the drive and bring in anything delicate from around the walls. If you have pets, keep them inside while we are working overhead, and let us know about any ponds so we can take extra care.

Some customers like to finish the job with a clean of the drive once all the moss is down. Our driveway cleaning can be booked for the same visit and includes a free bin clean.

Yes, smaller roofs often need it as much as the main roof. Garage roofs, porch canopies and the little tiled roofs over bay windows sit lower down, get more shade from hedges and trees, and catch moss falling from the roof above. They can end up thick with growth even when the main roof looks fairly clear.

We use the same careful scrape and biocide method on these roofs, taking extra care around lead flashing and the joints where they meet the house wall. If you only want the small roofs doing, that is fine, and if you are having the main roof cleaned we can include them at the same time.

Bay roofs and porches often leave green streaks on the brickwork below where water runs off. Our brickwork cleaning can lift those stains on the same visit so the whole front of the house looks fresh, clean and properly finished.
