Prevention is cheaper than removal. If your roof only needs holding, we’ll tell you — and charge you a third of a wash.
A single application that stops new moss, mould and lichen establishing. For roofs with minimal growth, or maintenance between RoofShield™ cycles.
Our two-visit system: two treatments, a follow-up call, and a 12-month no-new-growth guarantee. New growth inside the year gets a free booster.
Removes the buildup on the day — moss, mould, lichen, dirt and salt off the surface, safely, on any roofing material.
Nothing gets blasted off your roof.
High pressure strips the coating off tiles and drives water under the laps. So we never blast — your roof is either treated and left for the weather to finish the job, or soft washed clean on the day.
Roof treatment
An EPA-approved biocide applied across the whole roof, your planting pre-rinsed and protected first. It kills moss, lichen and algae at the root — then rain and wind carry the dead growth away. Full results take up to 12 months; established growth sometimes needs a second application.
Soft wash
For when it needs to be clean on the day: cleaning solution on, a soft-bristled brush where it’s needed, a final low-pressure rinse — and every bit of dislodged material cleaned up before we leave.
Which one?
Treatment is the lighter-touch path when the weather can finish the job for you; a wash is for buildup that has to go today. Your proposal recommends one, and the reasoning comes with it.
Colorsteel, one wash.

Roof questions, answered.
Q1What’s the difference between RoofShield™ and a standard treatment?
RoofShield™ is our premium two-visit system designed to remove existing moss, mould and lichen, with a follow-up call and a 12-month no-new-growth guarantee. A standard Roof Treatment is a single preventative application designed to stop new growth establishing — ideal for maintenance, or for roofs with minimal existing growth.
Q2What’s the difference between treatment and washing?
Treatment is preventative — it stops new growth establishing. Washing physically removes existing dust, dirt, salt, moss, mould and lichen from the surface. Treatment is for prevention, washing is for removal.
Q3Is it safe for my roof material?
Yes. All our treatment and washing methods are safe for every type of roofing material — we use gentle professional techniques that clean without causing damage.
Q4How often should I have my roof treated or washed?
RoofShield™ typically holds for 12+ months. A standard treatment may need reapplying sooner depending on conditions. Washing can be done annually or as needed.
Q5How long does it take?
A roof treatment is typically 1–2 hours. A roof wash takes 4–12 hours depending on size and condition. RoofShield™ is two separate visits. We’ll give you a firmer estimate after the initial assessment.
Q6What does the RoofShield™ guarantee actually cover?
No new growth for 12 months from the date of the second treatment visit — if new growth appears in that window, we provide a free booster treatment. It doesn’t cover areas outside the original scope, or the gradual natural breakdown of existing dead growth. Full terms are on the RoofShield Guarantee page.

“⭐⭐⭐⭐⭐ I’ve used Pinnacle Building Wash previously and went back to them because of the professional and personalised service they provided the first time around. I continue to be so impressed with their customer service. I had Aaron back again to clean the house and water blast the paths and driveway — a mammoth job! He did a splendid job, as always. Then yesterday, the lovely Jack came around to treat the roof for lichen. Wow — what an amazing job! I’m super impressed with the results. Both Aaron and Jack are extremely knowledgeable, friendly and helpful. They’re always happy to tackle those extra little odd jobs and genuinely go the extra mile to make sure everything is done properly. They’re a super lovely crew, and it’s clear they really care about the work they do. I also really appreciate that they’re happy to work with your budget and can come back when you’re ready to save up for the next lot of work. That kind of flexibility and understanding makes such a difference. Unfortunately I did not take any before photos but I've put up some photos of the final results. I’ll definitely be keeping Pinnacle Building Wash on my books and would highly recommend them to anyone looking for this type of service. I’m based in Ngaio, Wellington, but I believe they work throughout the Wellington area — give them a buzz. You won’t be disappointed! 😊
“[Edit: 1 November 2026. I'm a returning customer. This time we got a gutter clean and external wash. Outstanding as usual. I recommend Pinnacle to anyone in the Hutt region!] Pinnacle are excellent! We moved in not long ago and, being winter, hadn't had the chance to pay any attention to the outside of the house. Two ceiling leaks later, we found Pinnacle. They do great work, the place was so tidy when we got home it was as if they'd never been. The only sign was that the external walls of the house were much cleaner than before 😂 We also got before and after photos of the gutters. Since we can't get up that high, we got to see just how awesome they were. I'd definitely use Pinnacle again, though I'm sure they won't want to come back in a hurry lol. Thanks team!
“Great service and outstanding cleaning of our monolithic house. Nothing a problem and provided great advice. Highly recommend Pinnacle Building Wash.
“Pre sale house wash, and what a difference it’s made! Wish we’d done it sooner because the house looks awesome. Thanks Jack 👏🏻
