Moss, lichen and mould don’t just make a roof look tired. They hold moisture against the surface, lift and stain coatings, and wash debris into your gutters. Left long enough, that build-up shortens the life of the roof and can lead to leaks.
The Washdown King cleans and treats long run iron and tile roofs across Christchurch. We use the same gentle soft washing approach we use on houses: a cleaning solution that breaks down moss, lichen and mould, followed by a low-pressure rinse with purified water. A roof clean will:

1. Roof inspection
We check the roof type, pitch, condition and access, and look for cracked tiles, loose fixings or worn coatings that need extra care.
2. Safety set-up
We plan safe access for the job. For high or hard-to-reach roofs, our spray drone can apply the cleaning solution from the ground.
3. Treatment
We apply a cleaning solution that breaks down moss, lichen and mould, and give it time to work into the surface.
4. Low-pressure rinse
We rinse the roof with purified water at low pressure, which avoids the damage high-pressure blasting can do to tiles and coatings.
5. Gutters and final check
We clear any debris that has washed into the gutters and walk the property to make sure nothing has been missed.
Every roof is different, so we price each job individually, and the quote is free. The main things that affect the cost are:
Booking your roof, gutters and house wash in the same visit saves a second call-out. Tell us about your roof in the quote form and we’ll come back with a clear price.
We clean and treat long run iron and tile roofs on homes, sheds and commercial buildings across Christchurch. If you’re not sure whether your roof is suitable, send us a photo with your quote request and we’ll let you know.
While we’re cleaning your roof, we can also clear out your gutters. Regularly cleaning your gutters can extend the life of your roof, stop pests from nesting, and prevent water damage inside your home when the rain has nowhere else to go.
Some roofs are too high, steep or fragile to walk on safely. Our drone roof cleaning service applies the treatment from the air, so there is less need for scaffolding or a cherry picker.
A clean roof often shows up how much the rest of the house needs a wash. Add a house wash to the same visit and we’ll clean your cladding, windows, decks and paths while we’re there.
We clean roofs right across Christchurch, including Cashmere, Halswell, Hornby, Riccarton, Fendalton, Merivale, Papanui, Burnside, Shirley, Linwood, Sumner and Redcliffs, as well as Rolleston, Lincoln, Prebbleton, Rangiora and Kaiapoi. If you’re elsewhere in Canterbury, get in touch and we’ll let you know if we can help.
Most roofs benefit from a clean every one to three years. Roofs under trees, in shade or in damp spots grow moss and lichen faster, so they may need it more often.
Not with the right method. We use a cleaning solution and a low-pressure rinse instead of blasting the roof at high pressure, which can crack tiles and strip coatings.
Yes. We can clear your gutters in the same visit, along with a house wash, deck, fence, path or driveway clean. Tick everything you need on the quote form.
Yes. For high, steep or fragile roofs, our spray drone can apply the cleaning solution from the ground, reducing the need for scaffolding or a cherry picker.
