Part of our house wash & exterior services in Wellington.
Damp, shady, bush-side roofs are common in Wellington, and they grow moss and lichen well. If yours has a bit of growth but nothing drastic, a roof treatment is an easy fix.
How it works
- We look over the roof and protect the garden below.
- We spray a salt-based treatment over the growth.
- Over 4 to 6 weeks it kills the moss and lichen at the roots.
- Over the next 8 to 12 months, wind and rain clear the dead growth away.
Treatment or cleaning?
Treatment is slow and hands-off. Good for light to medium growth and keeping a clean roof clean.
Roof cleaning is a wash, looks clean the same day, and is the one to get before painting or selling.
Lots of people clean once, then treat every few years after.
How often
Every two to three years for most Wellington roofs.

Keep the gutters clear
Some of the dead moss will wash into the spouting. A gutter clean later in the year keeps it flowing.
Roof treatment questions
How does roof treatment work?
It's a spray-and-leave job. We cover the roof with a salt-based solution, and over 4 to 6 weeks it works into the build-up and kills the moss and lichen. The dead growth then weathers away over the next 8 to 12 months, so there's no water blasting involved.
When's the best time to get a roof treatment in Wellington?
Spring or autumn, when the weather is mild and there's less rain. The treatment needs a dry spell after it goes on so it isn't washed off before it soaks in, and it's best sprayed on a calm day. In Wellington that means watching the forecast for wind as well as rain.
How long does a roof treatment last?
Most roofs need treating again every 2 to 3 years. Exposed roofs and ones under trees might need it a bit sooner.
Does roof treatment work on all types of roof?
It suits most roofs, including metal and concrete tile. There's no pressure involved, so it's a good option for older roofs. Not sure about yours? Ask us.
How much does roof treatment cost in Wellington?
It depends on the size and pitch of the roof, how much growth there is and access. Get in touch for a quote.
Do I need a roof clean as well as a treatment?
Not usually. A treatment on its own clears moss and lichen, it just takes a few months. If you want the roof clean now, for painting or selling, a roof clean is the quicker option.
