Three treatments. One honest assessment.

We don't clean every roof the same way.

Most cleaners run one method on everything. We don't. We look at the tiles, the moss load, the elevation, the tree cover, and recommends one of three: a gentle wash, moss scrape, or pressure wash, each finished with a treatment that stops the moss coming back, whichever protects the roof and keeps it clean the longest.

Sometimes that means we say no, the roof needs a re-point first, or it is too fragile for any of the three. You get the honest answer either way, in writing, by text within 24 hours.

Three treatments

We assess, then recommend one.

Three treatments cover every Aberdeen and Aberdeenshire roof we work on. Which one your roof needs depends on the moss load, the tile type, the elevation, and how long you want the clean to last.

Professional pressure wash + biocide moss-stop

A controlled, even spray + a hand-scrape on the worst patches + a full moss-stop treatment that keeps it from coming back. Surface-safe on hardy tiles, we never blast directly at the roof. The option most Aberdeen customers ask for, it clears heavy moss + algae in a single visit.

Sometimes the answer is "not yet". If the tiles are too fragile or the verge needs re-pointing first, Scott will say so. Honest assessment, in writing, within 24 hours.

Problems we fix

If you see any of these, send a photo.

Most Aberdeen roof problems sort in a single visit. The moss-stop treatment does the heavy lifting after we leave.

  1. 01
    Heavy moss. The classic Aberdeen problem. Holds moisture, blocks valleys, gets worse every winter.
  2. 02
    Lichen patches. Crusty grey-green spots, often on north-facing slopes. Our treatment kills it at the root.
  3. 03
    Algae streaks. Black or dark-green vertical lines that make the whole house read "tired" from the kerb.
  4. 04
    Blocked gutters. Moss shedding into gutters is often the first symptom. By the time you see overflow, the roof needs a clean.
  5. 05
    Cracked verge sealant. Spotted during inspection. We flag it; you decide whether to re-point before or after.
  6. 06
    Bird droppings. Acidic, etches tile glaze over time. We treat it as part of the pass, no extra charge.

When the clean reveals more

A clean roof shows you what was hiding.

Once the moss and algae come off, anything underneath is finally visible. If Scott spots damage, he photographs it and shows you - no scare tactics, no pressure. If it needs sorting, we can arrange the repair after the clean.

Worn or slipped ridges

Ridge tiles that have slipped, cracked or lost their bedding - common on older Aberdeen roofs and easy to miss under moss.

Cracked or porous tiles

Hairline cracks and tiles that have gone porous let water in. We flag the ones worth replacing before they cause a leak.

Failed pointing

Cracked or missing mortar at verges and ridges. Re-pointing keeps the wind and rain out once the roof is clean.

Blocked valleys

Valleys packed with moss debris stop water draining. We clear them on the clean and tell you if the lining needs work.

Cleaning first, repairs only if you want them. Most roofs just need a clean. If yours needs more, you get the photos and an honest answer in writing - then you decide. We can arrange the repair after the clean, or you can take the photos to your own roofer. Either way, no obligation.

Roof FAQ

Roof cleaning, answered.

Scott decides after the assessment, based on the moss load + tile type + elevation + tree cover. Light moss or fragile tiles usually get a gentle wash plus the moss-stop treatment. Moderate to heavy moss on standard tiles usually gets a moss scrape plus the treatment, the most common Aberdeen job. Heavy moss + algae on hardy concrete sometimes needs the full pressure wash plus the treatment. You get the recommendation in writing before booking, with the reasoning.
Yes, fully insured for every job, certificate available before we start. Scott is IPAF-trained for safe powered-access work at height. RAMS provided on request.
Not with us. When pressure is appropriate, we use a gentle, controlled spray, never the lance-on-tile blasting that cracks slate. On fragile or heritage roofs we skip pressure entirely and use the gentle-wash route instead. The moss-stop treatment is what actually kills the regrowth, not the pressure.
The treatment carries on killing moss and algae at the root for months after we leave. The exact window depends on roof type and surrounding tree cover, north-facing roofs under canopy regrow soonest. Scott tells you what to expect for your specific roof before booking.
No. If we have safe access and an outside tap (or we bring our own water supply), we can complete the job and text photos when finished. Most customers leave us to it.
We clear the moss and debris we have scraped off the roof as part of every clean, including anything that has shed into the guttering on completion. We leave the site tidy and tell you honestly if we spot anything that needs a separate look.
Yes, gentle-wash only. We come look first before quoting if the roof is older than 1950, and we use a gentler, longer-lasting treatment suited to heritage tiles. Often a two-visit job.
Quote back within 24 hours, often same afternoon. Booked-in jobs are typically 1-2 weeks out in peak season (April-October) and 3-5 days in winter.

Semi in Bridge of Don, the north side has gone green. How much to sort it 09:14
Got it, cheers. That is moderate moss on slate, mostly the north slope. A moss scrape + moss-stop treatment will clear it in one visit and keep it off. 10:38
