Roof Cleaning & Gutter Cleaning Rotorua

Rotorua Roof Cleaning Specialists

Protect your roof and keep it in top condition with Chemwash Rotorua. Our professional roof and gutter cleaning services use gentle, effective methods designed to maintain your roof for years to come. We can clean all types of roofing, from Colorsteel & scope-painted iron to clay & concrete tile.

Roof Treatments

For long-lasting protection against moss, mould, and lichen, Chemwash Rotorua offers specialised roof spray treatments designed to deliver results that last. Our process targets unwanted growth at the source, then lets nature take care of the rest. The rain and wind gradually rinse away the dead material over the following months.

While the change won’t be immediate, the outcome is a roof that remains cleaner for far longer. The treatment also reactivates whenever it rains, continuing to guard your roof from regrowth season after season. It’s a practical, low-maintenance solution for keeping your roof looking great year-round.

To maintain lasting results, we suggest reapplying the spray treatment roughly every two years. Each treatment is also backed by a two-year warranty, giving you total peace of mind and guaranteed results.

Gutter Cleaning

An important part of keeping your roof clean is ensuring your gutters are clear. Blocked gutters can lead to larger problems later on if not cleared, so it is important to keep on top of this. If your gutters are dirty or overflowing, we can help.

We recommend an annual clearing of your gutters to prevent blockages and possible water ingress. Why not get us to tackle them at the same time we are cleaning your roof?

Frequently Asked Questions

Roof cleaning vs roof treatment… what’s the difference?

These two services often get lumped together, but they actually do very different jobs. A Roof Clean is all about instant results. We gently remove surface dirt, grime and buildup using our low-pressure system, so your roof looks fresher straight away. It’s a great option if you’re getting ready to paint, sell, or you just want the place looking sharper without having to wait. A Roof Treatment is more of a long game. Instead of blasting growth off, the treatment targets moss, mould and lichen right down at the root. Once applied, it reactivates with rainfall and lets nature do the work over time, gradually washing the roof clean. This helps slow down regrowth, and can add years to the life of your roof, especially important for older roofing materials. Don’t worry, we’ll always recommend what’s genuinely best for your roof. No pressure, no upselling, just honest advice.

When will I notice results from a roof treatment?

Roof treatments aren’t designed to work overnight, and that’s actually intentional. The slower process is much gentler on your roof and avoids unnecessary stress on the surface. How quickly you’ll notice changes depends on a few things: how heavy the moss or lichen is, the time of year, rainfall, and the surrounding environment. In most cases, you’ll see visible improvement over a few months. When you book a free quote, we can give you a realistic idea of what to expect based on your property. Once the roof comes up clean, it usually stays that way for much longer than a standard wash.

Could cleaning damage an older roof or cause leaks?

We get this question a lot, and it’s a fair one. After all, roof repairs aren’t cheap, and that’s exactly why we don’t water blast roofs. Our low-pressure methods are chosen to suit the age and condition of your roof, not fight against it. The goal is protection and maintenance, not pushing things too hard. If we spot any existing issues that could cause problems, we’ll let you know before we start. No surprises, no risks taken.

Can gutter cleaning be done at the same time?

Absolutely. If we’re already up there, it makes sense. Blocked gutters can lead to overflows or water damage if left too long. Let us know when you request your free quote and we can include gutter cleaning at the same time.

Is roof cleaning actually worth it?

For most homeowners, yes. Many of our customers get their roof cleaned or treated every year or two as part of regular maintenance. A clean, well-maintained roof lasts longer, protects the rest of the house, reduces the risk of leaks, and gives your place a noticeable lift in street appeal. More importantly, it can help you avoid much bigger repair bills down the track. Our quotes are always free, clear, and come with no obligation, so you can make an informed call with confidence. If you’re unsure which option suits your roof, just get in touch. We’re always happy to have a look and point you in the right direction.

What Our Clients Are Saying

Gareth

I got Chemwash to do a complete exterior wall and roof wash down of my house to give it a new lease of life. The service was amazing! A visit was arranged, a competitive quote was provided, and the job was completed all within very quick time. The contact that I had with the team was all very professional and courteous. The team who did the work were amazing, they went the extra mile with moving the kid’s toys, working around the dog and cleaning things that I hadn’t expected to be included. And the end result is amazing! My house now looks new – sparkling clean and it even smells clean! I have absolutely no hesitation to recommend Chemwash, and I know I will be using them again in the future.
