Roof Cleaning in Dorset, to restore its appearance.

Over time, roofs naturally collect moss, algae, lichen and other organic growth. Our professional service safely removes this build-up, and every roof starts with a free assessment.

Honest advice before any work begins

Restore the Appearance of Your Roof

Roof cleaning in Dorset means dealing with moss. Our mild, damp winters grow it thick, especially on north-facing pitches. Left alone, moss holds water against your tiles through every frost, blocks your gutters with debris, and in heavy rain sheds clumps that dam your downpipes.

Every roof is assessed individually before any work begins. We'll recommend the most appropriate cleaning method based on the condition of your roof and the type of tiles or roofing material involved, from manual moss removal to specialist roof cleaning techniques, with a suitable biocide treatment applied where appropriate.

Every Roof Clean Starts With a Free Assessment

Not every mossy roof needs a full clean, and not every roof is suitable for one. Older tiles, delicate ridge work and certain coatings need different handling.

That's why we assess first, tell you what it genuinely needs, and quote a fixed price. If the answer is "leave it another couple of years", that's what we'll say.

Assessments are free across Dorchester, Poundbury and the surrounding villages, and there's no obligation on the quote.

Our 4-Step Roof Clean

how it works
1

Free Assessment

We inspect your roof and inside the loft space to assess its condition, then provide a fixed price for the service. If it doesn't need doing, we'll say so.

2

The Cleaning Process

Your roof is cleaned using the most appropriate cleaning method based on the condition of your roof and the type of tiles or roofing materials involved.

3

Biocide Treatment

Where appropriate, a suitable biocide treatment is applied. This ensures moss regrowth is significantly reduced moving forward.

4

Gutters & Windows Cleaned

All that moss and roof debris ends up somewhere. We clear the gutters, clean the windows and tidy the ground before we leave, leaving everything clean and tidy.

Roof Cleaning Questions, Answered

How much does roof cleaning cost in Dorset?

Every roof is assessed and quoted individually. Each clean will depend on factors such as roof height, roof pitch, access, roofing material and site conditions. The assessment provides a fixed cost with no obligation, and if we don't think the roof needs cleaning, we'll say so.

Is roof cleaning actually worth it?

Not only for aesthetic reasons, but also to protect your property. If moss is established, it holds moisture against tiles through winter, it can freeze-thaw, block gutters and downpipes, and hide small defects until they eventually leak.

How often should a roof be cleaned?

With a biocide treatment, a cleaned roof typically stays clear for 3–5 years. North-facing pitches and homes near trees sit at the shorter end. It's a periodic job, not an annual one.

What's the best time of year for roof cleaning?

Dry spells in spring through autumn are ideal, because biocide needs a dry roof to soak in properly. To ensure it's as effective as possible, we'll return to apply a treatment if the weather requires it.

Will you clear up the moss afterwards?

Yes. Gutter clearance, window cleaning and a full ground tidy-up are part of every roof clean.
