Moss Removal That Protects Your Roof
Moss traps moisture against tiles, works its way under them and, once it washes down, ends up clogging the gutters below. Rather than blasting a roof directly with a high-pressure jet, which can crack tiles or force water underneath, ECR removes moss by careful brushing and scraping, then treats the roof to slow regrowth.
Because we're up there anyway, it's a good opportunity to check ridge tiles, flashing and valleys for anything loose or damaged, and to flag it honestly rather than leave it for you to find out the hard way. Any debris that's come loose is cleared from the gutters before we finish, so the job is left properly tidy.
- Moss, algae and lichen safely removed from tiles and slate
- Gentle methods that protect tiles rather than blast them
- Roof treated to help slow down moss regrowth
- Ridge tiles, flashing and valleys checked while we're up there
- Debris cleared from gutters as part of the job
Common questions
Roof Cleaning FAQs
What is roof cleaning and how does it work?
Roof cleaning removes moss, algae and lichen from tiled or slate roofs, usually by careful brushing and scraping followed by a treatment that slows down regrowth. Gentle methods are generally preferred over high-pressure jet washing, since forceful water can lift or crack roof tiles and force moisture underneath them.
Is roof cleaning safe for older tiles?
Generally yes, as long as the method suits the roof. Tiles are assessed first, with gentle brushing and treatment used rather than aggressive pressure washing, which is where most damage to older or more brittle tiles comes from.
Will this stop moss coming back for good?
It will slow it down significantly, but no treatment stops moss returning forever, especially on shaded, north-facing roofs. Periodic treatment every couple of years keeps growth well under control without needing a full clean each time.
Do you clean flat roofs too?
Yes, flat and felt roofs are cleared of moss, leaves and general debris using methods appropriate to the roof covering, helping outlets stay clear and water drain away properly.
How long does roof cleaning take?
A standard semi-detached roof usually takes half a day to a full day, depending on the size, pitch and how much moss has built up. Steeper roofs or roofs with several valleys and awkward junctions generally take longer, since access and safety considerations slow the work down.
Is roof cleaning something to attempt myself?
Roof cleaning carries genuine fall risk and is generally not something to attempt without proper access equipment and training, particularly on a pitched roof at height. Incorrect technique, such as pressure washing directly onto tiles, can also cause damage that's expensive to put right.
What to expect
Before Any of That Starts
A free quote and a clear explanation of the method come before any work is booked in, since roof cleaning genuinely varies by roof type and condition. Access equipment is used safely and properly, not a ladder propped against the guttering. Debris that's come loose during the clean is cleared from the gutters before the job is finished.
