What's actually growing on your roof?

Most Manchester roofs pick up three things. They look different, they do different damage, and they need treating, not just blasting off.

Thick green moss on roof tiles

Moss

Holds water like a sponge, creeps between tiles and ends up blocking your gutters when it falls.

Moss clumps and yellow lichen on slate

Lichen

Crusty yellow-grey patches that grip the tile surface. Scraping alone won't shift it.

Dark staining on clay roof tiles

Black streaks

Algae that spreads down the roof in dark stripes, usually worst on shaded slopes.

How we clean a roof

  1. Check and protect

    We look over the roof first and protect paths, plants and cars below.

  2. Moss off by hand

    The bulk of the moss is removed by hand, so tiles aren't damaged.

  3. Treatment applied

    A biocide treatment kills lichen, algae and spores, and keeps working after we leave.

  4. Gutters cleared, photos sent

    Everything that comes off is cleared from gutters and downpipes, and you get your before and after photos.

All FAQs
How much does roof cleaning cost in Manchester?

It depends on the size of the roof, the pitch, access and how much growth there is. The quickest way to find out is to Email us a few photos with your house number and postcode. We measure the roof remotely and send an estimate.

Will roof cleaning damage my tiles?

No. The bulk of the moss is taken off by hand and the roof is then treated, so we're working with your tiles rather than against them. We'll talk you through the method for your roof before we start.

How long does a roof clean last?

The treatment keeps working after we leave and slows regrowth, but how long a roof stays clean depends on shade, nearby trees and which way it faces. We'll give you honest advice for your roof.

Do I need to be home while you clean?

Not usually. As long as we can get to the area we're cleaning, we agree access beforehand and send you before and after photos when the job is done.

Which areas do you cover?

We're based in South Manchester and work across Trafford, Stockport and Cheshire, including Sale, Altrincham, Timperley, Hale, Didsbury, Chorlton, Cheadle, Stockport, Bramhall, Knutsford and Macclesfield.
