EVERY ROOF IS DIFFERENT

Why roof cleaning can be worth it

Your roof is constantly exposed to the elements, accumulating dirt, moss, algae, and lichen over time. Not only does this affect your property's appearance, but it can also cause serious damage if left untreated.

A roof cleaning specialist removes moss and debris and can treat the roof to slow regrowth. We do not clean roofs ourselves: we pass your enquiry to a specialist who covers your area.

What a clean can help with

Tidier appearance

A clean roof and clear gutters make a home look cared for.

Less moisture on tiles

Thick moss holds water against tiles and can lift them as it grows.

Clearer gutters

Moss that washes off the roof blocks gutters and downpipes, so clear them too.

Damage spotted early

Slipped or cracked tiles are easier to see once the moss has gone.

Slower regrowth

A biocide treatment after cleaning helps slow moss and algae coming back.

The right method

Pressure washing is not suitable for every roof. Ask how yours will be cleaned.

What to ask a roof cleaner

Which method?

Hand removal, soft washing or pressure washing, and why it suits your roof.

Is a biocide included?

And which product, as it affects how soon moss comes back.

Are they insured?

Ask to see public liability insurance before work starts.

How will they reach the roof?

Safe access may need scaffolding or a platform, which can add to the price.

Are gutters cleared afterwards?

Debris often ends up in the gutters; check it is included.

Is the quote in writing?

Including VAT, access and any treatment or repairs.
