Roof Moss Removal in Stratford
Roof Cleaning and Moss Removal in Stratford
Moss behaves differently on the different roofs you find in Stratford. On the Victorian terraces around Maryland and West Ham Lane it grows on shaded slate and tile slopes in the usual way. On the newer blocks and flat-roofed extensions in E15 and E20, the problem is more often a green film of moss and algae where water lingers, especially around outlets and along low edges. Ashlar Roofing carries out roof moss removal across Stratford and the London Borough of Newham, on pitched and flat roofs alike.
On a pitched roof, moss holds water against the covering and works its way into the joins between tiles. On a flat roof, it traps silt and leaves, which then block outlets so rainwater ponds. Ponding wears out a membrane far sooner than it should, so clearing growth from a flat roof protects the covering as much as it tidies the view from the windows above.
Either way, the work is done by hand. We scrape and brush the growth away rather than blasting it, then treat the surface and clear the drainage.

Blocks, Extensions and Managing Agents in E15 and E20
For flats, roof cleaning is usually arranged by the freeholder or managing agent as part of planned maintenance. We can survey, photograph the growth and outlets, and provide a quote that sets out exactly what is included, so it can be approved and scheduled without repeated visits. Access to a block roof is arranged with whoever holds the keys.
Flat roofs need a gentler hand than pitched ones. Rubber, felt and fibreglass coverings can be damaged by sharp scrapers or stiff wire brushes, so we use tools suited to the membrane and take care around seams, upstands and rooflights. Outlets and gutters are cleared at the end so the roof drains properly.
On houses in the Stratford St John’s conservation area, cleaning does not change the roof’s appearance and needs no consent. If the clean reveals slipped slates or tired leadwork, we point it out and price any repair separately.


What's included
What a Roof Moss Removal Visit Covers
The main parts of the job, each listed in your quote.
- Moss lifted off by hand with scrapers and brushes, working down the slope so tiles are not forced up.
- No pressure washing, which can strip tile surfaces and drive water under the laps.
- A biocide treatment over the cleaned roof to kill remaining spores and slow regrowth.
- Valleys, hips and ridges cleared, as moss gathers where water runs slowest.
- Gutters, outlets and downpipes cleared of the moss washed into them.
- Photos of any slipped, cracked or loose tiles found while we are on the roof.

Pricing
Pricing a Roof Clean in Stratford
In Stratford, a roof cleaning quote depends on:
- The area and pitch of the roof
- How thick the moss is and how long it has been growing
- Access, including whether a tower or scaffold is needed
- The covering, as fragile clay, slate and older concrete tiles need more care
- How much gutter and downpipe clearance follows the clean
