Moss treatments
Don't let lichen and moss reduce the lifespan of your roof, our soft application treatments help to protect your property.
MOSS TREATMENTS FOR LONG LASTING ROOFS
Why Regular Moss Treatments Are Important
A moss treatment is a low-pressure spray that kills moss, lichen and mould on your roof. The dead growth then breaks down and washes off with the rain over the following weeks and months. Left untreated, moss and lichen hold moisture against your roof, block water channels and gutters, and break down tiles and coatings, shortening your roof's life.
- Longer roof life: Removing growth stops it holding moisture against tiles, iron and coatings, so your roof wears more slowly.
- Fewer leaks and blockages: Moss builds up in tile laps, valleys and gutters. Clearing it keeps water running off the roof, not under it.
- No damage to your roof: We apply treatments at low pressure, with none of the water blasting that can strip coatings or wear down tile surfaces.
- Better street appeal: A clean roof lifts the look and value of your whole property.
WHAT'S INCLUDED
Every restoration includes
White Roofing offers a range of maintenance services tailored to your roof’s specific needs, ensuring it remains in top condition year-round. Our services include:
Roof inspection
We check how far moss, lichen and mould have spread, and look for broken tiles, loose fixings or worn coating while we're up there.
Soft, low-pressure application:
We apply Moss Treatment evenly across the whole roof, including ridges, valleys and shaded slopes where growth is heaviest.
Rainwater tank and garden protection
We disconnect downpipes feeding rainwater tanks before treating, tell you when it's safe to reconnect, and avoid overspray onto gardens and paths.
• Condition report
Photos and a short note on anything that needs attention, so small problems get fixed before they become leaks.
Why Moss Treat Your Roof
Stop moss and lichen before they cause damage
Moss and lichen thrive in the humid climate of Auckland and Tauranga, especially on shaded and south-facing roof slopes. The longer they grow, the more damage they do and the longer they take to clear. •
- Protect your tiles and coatings: Lichen anchors itself into the surface of tiles and roof paint and can leave marks once it's gone. Treating early limits that damage.
- Keep water flowing off the roof: Moss traps debris in tile laps, valleys and gutters, slowing drainage and letting water back up under your roof.
- No water blasting needed: Water blasting can strip coatings, wear down tile surfaces and force water under tile laps. Our treatment works with the weather instead, so your roof's surface stays intact.
- Results that keep improving: Moss starts dying off within weeks. Lichen takes longer, often several months, to break down and wash away, so your roof keeps getting cleaner after we leave.
- Protect your insurance cover: Most home insurance policies don't cover damage from gradual deterioration or lack of maintenance. A treatment record helps show your roof has been looked after.
- Get ready for a restoration or sale: A clean roof lifts your property's first impression when you sell, and is the right starting point if a restoration is on the cards.

FAQ
Got questions? We've got answers
How long does a roof restoration take?
Most roof restorations on an average home take 3–7 working days. The time depends on the roof’s size and material, how much repair work is needed, and the weather, since coatings can’t go onto a wet roof or be applied in rain. Your roof stays on the whole time, so unlike a re-roof you can carry on living at home as normal.
How much does a roof restoration cost in New Zealand?
A roof restoration for an average New Zealand home typically costs $4000-$7000. The price depends on the roof’s size, pitch, material and condition, and how much repair is needed before coating. That’s a fraction of the cost of replacing the roof: re-roofing a standard Auckland home costs around $14,000 -$32,000 in long-run steel, and $22,000 - $45,000 or more for concrete or clay tile conversion. White Roofing provides free on-site quotes in Auckland and Tauranga.
Is roof restoration worth it, or should I replace my roof?
Roof restoration is worth it if your roof is structurally sound but worn, faded or starting to rust. It costs far less than a re-roof and can add 10 or more years of life. Replacement is the better investment when the roof has reached the end of its life. Signs include iron that has rusted through, tiles breaking down across the whole roof, or ongoing leaks from failed materials. A proper inspection will tell you which one you need.
How long does a roof restoration last?
A quality roof restoration typically lasts 10 years or more, depending on the coating system, the preparation and how exposed your home is. Resene puts the average repaint interval for New Zealand roofs at 8–10 years for standard roof paint, while multi-coat membrane systems are built to last longer. White Roofing uses Shieldcoat membrane systems, which carry 10+ year performance guarantees.
