Look north from Bishopbriggs on a clear day and the Campsie Fells fill the skyline. On most other days they are wrapped in cloud, and the rain they gather drifts down over the town. At Lennoxtown the slopes rise almost from the end of the streets, so roofs there get the brunt of it. The Forth and Clyde Canal and the wet ground of Lenzie Moss add yet more moisture to the air.
The roofs are as mixed as the landscape. Lenzie grew around its railway station in Victorian times, leaving streets of stone villas with slate roofs. Bishopbriggs is largely twentieth-century suburban housing, much of it under concrete tiles, while Lennoxtown combines older terraces with newer estates. Damp, shaded slopes on any of these will gather moss quickly.
Moss doesn’t just sit on a roof; it keeps it permanently wet. On a sloping Victorian slate roof, water held in the growth seeps into the fine layers of the stone. Winter frosts then expand it, and over the years the slate’s surface peels away in flakes, weakening it until it breaks.
Suburban concrete tiles fail in a different way. Their rough surface lets moss grip hard, and the roots creep under the overlap, raising the tile until wind-blown rain can reach the felt underneath. Ridge mortar softens under constant moisture too. When chunks of moss eventually break off, they fill the gutters and block the outlets, so rainwater cascades down walls and over the windows, soaking fascias and leaving lasting stains.
First, we need to see the roof properly. That might mean a quick visit, or a video call if it’s easier for you, so we can check the material, pitch, access and how much moss has built up. You then receive one fixed price. There are no hidden extras and nobody will push you to book. Any slipped or damaged tiles are flagged before we start, and the ground around the house is covered before the first person goes up.
We begin with hand scrapers, tackling the heaviest growth first. The team clears each row from top to bottom, pulling moss out of the joints and away from the ridge without spraying the roof. This keeps the surface intact. Every scraping is bagged on the spot, so nothing ends up in your flower beds or blocking the drains.
Steam handles what scraping can't. At high temperature but with no more push than a garden hose, it kills algae, lichen and moss roots on contact. Old slate stays whole and mortar stays put, while grime that has darkened the roof for years lifts off. Slate, clay and concrete can all be cleaned this way, which suits the mix of roofs in the area.
To finish, we treat the entire roof with an eco-friendly, biodegradable biocide used by professionals. The tiles draw it into their pores, killing spores that would otherwise grow into new moss. With the treatment applied, you receive our written 3-year moss-free guarantee, and we only ask for payment once you're completely happy with the roof.
“Punctual, professional team. Delighted with my gleaming roof and stonework! Highly recommend Outside Clean Ltd.”
“We had our roof cleaned by Jamie and the Outside Clean team. A great job done and cleaned up when finished. Very pleased and would highly recommend.”
“Great to deal with. Well organised and presented. Arrived as scheduled to do full roof clean, completed and cleaned up when finished. Excellent result, difference is amazing.”
“What a fantastic job they did, my roof looks like new. As well as cleaning my roof they fully cleaned up after themselves — my garden looks better than it did before.”
“Attention to detail was spot on. We have had a previous roof scraped but it didn’t come up half as good as this time. Very happy with the job.”
“Can’t thank Jamie enough for the great job he did on our patios and drive. He worked through horrendous weather and goes over and above to help.”
Some firms still offer high-pressure roof cleaning because it’s fast. The trouble is what it leaves behind. Leading tile manufacturers warn that it can void their warranties, and on a weathered roof the damage is hard to undo. Here’s a straight comparison of the two, so you know what to ask before you hire anyone.
When the roof work is done, we turn straight to the guttering and downpipes, scooping out the moss and debris so water can drain freely. The windows are cleaned as well, so the house looks finished from top to bottom.
We protect the grounds before starting and gather every bit of debris into bags afterwards for responsible disposal. Washing down the whole house rounds off the visit, so you’re not left with any mess on the drive, the paths or the patio.
Before quoting, we work out how to reach your roof safely. Mobile towers and harness systems suit many family homes, while larger or taller properties may need scaffolding or a cherry picker. Where a roof is especially awkward, our team can use rope access.
Our people are trained, hold IPAF and PASMA cards and work with certified gear, and we carry SafeContractor approval. Liability insurance (public and employer’s) of up to £5 million applies to each job, under a policy designed around roofing work.
