Roof & Gutter Cleaning

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?
