Roof Cleaning for homes and businesses in Dorking

Dorking sits at the foot of the North Downs and plenty of properties here are built into a slope, which makes access the deciding factor on a roof cleaning job rather than the roof itself. A perfectly ordinary tiled roof becomes a serious undertaking when the ground drops away on one side and there is nowhere level to stand anything on.

Access decides the price and the method

On a level site, a standard two storey roof is straightforward to reach. On a sloping site the same roof can be three storeys above the ground on the low side, with soft or uneven ground and no room to set up.

That is why we look before quoting instead of pricing by roof area. What we are actually working out is whether we can get to it safely, from where, and with what. Sometimes the answer is that a section needs different access from the rest of the roof.

What happens below the roof matters too

On a sloping site everything that comes off the roof travels further and ends up somewhere less convenient: a terrace below, a neighbouring garden, a driveway on the low side. Moss coming off a high pitch on a slope does not land tidily.

We plan that in, containing the fall where we can and clearing up what lands below. On steeper sites it can be worth clearing the terrace or moving what is on it before we start, and we will say so when we quote.

How we work

  1. 1
    Ground survey and access plan

    We look at the tile type, the pitch, the condition and how we are getting up there safely. Concrete interlocking, clay plain tiles, slate and older stone slabs all need a different touch, and a brittle tile is a repair bill waiting to happen.

  2. 2
    Agree the method before anything gets touched

    Some roofs suit careful scraping of the dry moss, some suit a soft wash and biocide, some suit both, and a few are best left alone. We tell you which one yours is, including when the answer is that a clean is not worth doing.

  3. 3
    Remove the growth and control where it falls

    Moss coming off a roof goes straight into the gutters and all over the ground below. That wants managing as the work goes on rather than leaving a garden full of it.

  4. 4
    Clear the gutters and downpipes afterwards

    A roof clean that leaves the gutters packed with moss has only moved the problem. Clearing them is what finishing the job properly looks like, so it is worth confirming it is in your quote.

  5. 5
    Biocide treatment and the honest timescale

    Where a treatment is used, it keeps working for weeks or months after we leave. The roof carries on lightening instead of looking finished the same afternoon, and that is worth knowing upfront.

We assess each roof first and use the safest method for the tiles and pitch.

Good to know

Roof Cleaning in Dorking: your questions answered

Can you clean a roof on a house built into a slope?

Usually yes, and it needs looking at first. A sloping site can mean the same roof is a comfortable height on one side and a long way up on the other, with uneven ground and nowhere to set up safely. We assess access before quoting instead of pricing off roof area, because on a site like that the access is the job.

Why does roof cleaning cost more on some properties than others?

Access, more than anything. Two roofs of identical size can be completely different jobs if one is reachable from level ground and the other needs tower access set up on a slope. Pitch, covering type and how much growth is on there all matter as well, which is why every roof gets quoted individually rather than by the square metre.

Do you use scaffolding or ladders for roof cleaning?

Whichever the roof and the site call for, decided before the job, not on the day. Some roofs can be worked safely from ladders, some need tower access, and some are best done from the edges without walking the covering at all. If a roof cannot be reached safely with the access available, we say so rather than improvising something.

Will the garden below get covered in moss?

Not if it is planned for. Moss coming off a roof falls, and on a sloping site it travels further and lands somewhere less convenient. The fall wants containing where the layout allows, and whatever lands below wants clearing up. On steep sites it is sometimes worth clearing a terrace beforehand, and that gets raised at quote stage if it applies.
