Roof cleaning
Roof cleaning & moss removal
Moss, algae, lichen and built-up dirt removed with a method chosen for your roof, not the quickest one.
How we do it
Initial assessment
We look at the roof material, condition, access and level of growth, then explain the method and the result you can expect.
Careful moss removal
Heavy moss is removed by hand first, so large amounts of debris don't get washed into the gutters and drains.
Steam cleaning or softwashing
Controlled steam loosens stubborn dirt and growth, or a low-pressure softwash treats staining without excess force.
Finishing treatment
Where suitable, a treatment is applied to tackle remaining growth and slow its return. Some staining keeps lightening for weeks.
Final tidy-up
We clear dislodged debris from the work area and, if quoted, clean out the gutters afterwards.
Why roof cleaning matters
Your roof is the most exposed part of your property. Moisture, shade and airborne debris let moss, algae and lichen build up across the tiles. As well as making the house look neglected, this growth holds moisture, blocks gutters and adds wear if it's left.
Moss spreads into tile joints, valleys and rainwater channels, then breaks loose and drops into the gutters. Removing it shows the roof's original colour again and cuts down the debris washing into your guttering.
Common roof problems we treat
- Heavy moss across tiles and around joints
- Green, black or patchy organic staining
- Lichen fixed to the tile surface
- Loose moss collecting in valleys and gutters
- General dirt and weathering that dulls the roof
Suitable for different roof finishes
Concrete tiles, clay tiles and other finishes vary in age, coating and condition, and they respond differently to cleaning. That's why we never promise one method for every roof. We inspect first, point out any fragile areas, and choose a proportionate approach.
Roof cleaning FAQ
Will you pressure wash my roof?
Not as a rule. The right method depends on the roof material and its condition. After an inspection we may recommend careful manual moss removal, controlled steam cleaning, softwashing or a mix of these.
Will the roof look completely clean straight away?
Most of the improvement is visible on the day, but some treated organic staining keeps fading over the following weeks. We'll tell you what to expect for your roof before we start.
Can roof cleaning help with blocked gutters?
Yes. Removing loose moss means less debris falls into the gutters. We can also clear the gutters as part of the same job so nothing dislodged is left behind.
How often should a roof be cleaned?
There's no fixed interval. Shade, nearby trees, roof pitch and local conditions all change how fast growth returns. We'll advise on sensible maintenance once we've seen the roof.
