Extends Roof Lifespan
Soft Wash — No Pressure Damage
Hamilton & Waikato
Professional Roof Washing Services Hamilton
Moss, lichen, black algae and debris build up on NZ roofs fast — and left untreated, they eat into your roofing material and shorten its life. At Mr Clean Exterior Washing, we soft wash residential and commercial roofs across Hamilton and Waikato, removing organic growth without the damage that high-pressure cleaning causes.
We treat the cause, not just the symptom — so your roof stays cleaner for longer.
Roof Washing Done Right
High pressure strips protective coatings, blasts granules off tiles, and forces water under flashings. Our low-pressure soft wash method removes moss and lichen effectively — without any of that risk.
- Soft wash method — safe for all NZ roof types including iron, tile, and membrane
- Moss, lichen, and black algae removal
- Post-treatment applied to inhibit regrowth
- Gutters cleared of debris as standard
- Residential and commercial roofs
Moss and Lichen — More Damage Than You Think
Moss and lichen look like a cosmetic problem but they’re not. Moss holds moisture against your roofing material, accelerating rust on iron roofs and cracking on tiles. Lichen actually bonds to the surface and breaks it down over time. A professional wash removes them and a post-treatment keeps them off — protecting your roof for years.
Eco-Friendly Treatment, No Harsh Runoff
Our cleaning solutions are biodegradable and selected to be safe for your garden, stormwater system, and surrounding environment. We rinse thoroughly and leave your site clean and tidy.
Our Roof Washing Process
1. Roof inspection
We assess the type of roofing material, level of growth, and any areas needing special care such as flashings or skylights.
2. Gutter clearance
Debris is cleared from gutters before washing so runoff flows freely.
3. Cleaning solution application
A biodegradable solution is applied to break down moss, lichen, and algae at the root.
4. Low-pressure rinse
We rinse thoroughly at low pressure, protecting your roof surface and coatings.
5. Post-treatment application
A residual treatment is applied to inhibit regrowth and keep your roof cleaner for longer.
Reliable, Thorough, No Shortcuts.
Your roof is one of the most important parts of your home — and one of the most expensive to replace. At Mr Clean Exterior Washing, we use the correct method for every roof type and never cut corners. Tidy work, proper treatment, and results that last.
A Clean Roof Lasts Longer
Regular roof washing is one of the most cost-effective ways to extend the life of your roof. Removing moss and lichen before they cause structural damage can add years to your roofing material — and save you thousands on repairs or early replacement. Most Hamilton roofs benefit from a professional wash every 2–3 years.

FAQs
Q: Will roof washing damage my roof?
A: Not with us. We use a low-pressure soft wash method that removes moss and lichen safely — unlike high-pressure blasting, which can strip coatings, crack tiles, and void warranties.
Q: What types of roofs do you clean?
A: We clean all common NZ roof types including corrugated iron, Colorsteel, concrete and clay tiles, and membrane roofs.
Q: How often should I have my roof washed?
A: Every 2–3 years is typical for Hamilton homes. If you have heavy tree cover or a north-facing roof with high sun and moisture, more frequent cleans help prevent heavy buildup.
Q: Do you apply a treatment after washing?
A: Yes. We apply a residual post-treatment to inhibit moss and lichen regrowth — this is what makes the clean last significantly longer than a wash alone.
Q: Do you clean gutters at the same time?
A: We clear gutters of debris as part of the roof wash. If you need a full gutter clean including downpipe flush, we can add that on.
Q: Is the treatment safe for my garden and stormwater?
A: Yes. We use biodegradable solutions that are safe for plants, soil, and stormwater systems.
