How to maintain a new roof

A new roof is one of the biggest investments you can make in your home, and in Wellington’s climate it pays to look after it properly from day one. Strong winds, high UV levels, salty coastal air, and frequent moisture all take a toll over time. Even a brand-new roof needs regular care to stay in top condition and reach its full lifespan.

In New Zealand, most new roofs are long-run steel, with steel tile systems like Gerard Tiles also popular for renovations and period-style homes. These materials are designed to be durable and low maintenance, but they are not maintenance free. Keeping a new roof clean and protected is one of the best ways to avoid premature wear, staining, and costly repairs later on.

Why roof maintenance matters in Wellington

One of the most important parts of roof maintenance is keeping the roof surface and gutters clear. In Wellington, many homes are surrounded by trees, native bush, and reserves, particularly on the hills and in coastal areas. Wind regularly carries leaves, pollen, and organic debris onto roofs. When this material builds up, it traps moisture and creates the ideal environment for moss, mould, and lichen to grow. Blocked gutters can also cause water to sit where it should not, increasing the risk of corrosion even on a new steel roof.

Moss, mould, and lichen are some of the most common issues we see when cleaning roofs across Wellington and the wider region. These organisms thrive in damp, shaded conditions and can appear quickly, especially on south-facing roof areas or homes close to bush. While they might look minor at first, they hold moisture against the roof surface and slowly break down protective coatings. Over time, this can shorten the life of your roof and affect its appearance. Steel tile roofs, including Gerard tiles, are particularly prone because of their profile and surface texture.

DIY roof cleaning can cause more damage than you think

Many homeowners consider DIY roof cleaning, but this often causes more harm than good. High-pressure washing can damage roof coatings and force water into places it does not belong. Chlorine bleach is still commonly used in roof cleaning, but it can fade paintwork, accelerate corrosion, and harm surrounding plants, lawns, and garden beds. For Wellington homes surrounded by established vegetation, this is a real concern.

Professional roof cleaning is one of the most effective steps you can take to protect a new roof. When done correctly, it removes harmful organic growth and helps preserve the roof’s protective coating without causing damage. This is where working with team of professionals like us makes a noticeable difference.

Our specialist roof cleaning for long-term protection

Roof cleaning is our only service, and that focus is what makes us experts. We do not install roofs and we do not offer general roofing repairs. Instead, we specialise exclusively in roof cleaning and roof protection, using industry-leading products that are safe, effective, and designed for long-term results.

Because our team focuses solely on roof cleaning, and we all live right here in the Wellington Region, we understand local conditions and how they affect different roofing materials. Our only mission is to protect your investment and keep your roof looking clean and well maintained for longer.

How often a new roof needs cleaning depends on its exposure, location, and surrounding environment. Homes near the coast, close to trees, or backing onto reserves typically benefit from more regular inspections. Treating a roof early, before heavy growth takes hold, is far more cost effective than restoring a roof that has been left too long.

Maintaining a new roof is not about constant work or quick fixes. It is about choosing the right methods and the right professionals. A clean, well-protected roof lasts longer, performs better, and adds to the overall appearance and value of your home.
