Combe Down sits high above the city in Bath stone cottages, many with stone-tile roofs. The combination of porous stone, a heavy traditional roof covering and an exposed position makes it the most method-sensitive area we work in.

What we get called out for in Combe Down

Stone-tile roofs do not behave like modern tile

A traditional stone-tile roof is porous, heavy, and laid in diminishing courses with a lot of exposed edge. Moss roots into the surface rather than sitting on it, so a scrape takes stone with it, and pressure drives water into a covering that was never designed to shed it that way. These roofs get a low-pressure biocide treatment and then time — the growth dies and weathers off over the following weeks. It is not the fastest-looking result on the day, and it is the only approach that does not shorten the life of the roof.

Exposed position and working weather

Combe Down is high and exposed, which means wind stops work more often here than down in the city. We would rather move a booking than apply treatment in conditions where it will drift, and we will tell you that on the day rather than press on. Access is generally straightforward with off-street parking on most properties.

Frequently asked questions

Can you clean a Combe Down stone-tile roof?

Yes, with a low-pressure biocide treatment. What we will not do is scrape or pressure wash one — moss roots into porous stone tile, so scraping takes the tile surface with it.

How long before the roof looks clean?

Four to eight weeks. The treatment kills the growth and the weather takes it off. Anyone promising you an immediate transformation on a stone-tile roof is planning to do something you would not want done.

Why do you sometimes postpone on windy days?

Because treatment drifts in wind and we are not applying biocide onto a neighbour's planting or car. Moving the booking is the honest answer.
