Roof Cleaning & Moss Treatment in Hamilton

If your roof sits under trees or in a shady, damp corner of the section, there's a good chance moss and lichen have already started creeping across it. Hamilton's mild, wet climate is exactly the kind of environment they love, and once they take hold, they trap moisture against the roofing material, lift tiles, and quietly shorten the life of a roof that might otherwise have years left in it. Pressure washing seems like the obvious fix, but blasting tiles or coloursteel with a high-pressure wand often does more damage than the moss ever would. Our Roof Cleaning Hamilton service uses a gentler soft-wash approach instead, treating moss, lichen, and mould at the source so it doesn't just grow straight back. It's also usually the essential first step before any repaint or coating job goes ahead.

What's Involved in a Roof Clean

Soft-wash cleaning

We use low-pressure equipment and roof-safe cleaning solutions rather than high-pressure blasting, which can crack tiles and strip protective coatings off metal roofs.

Moss and lichen treatment

Targeted chemical treatments kill moss and lichen at the root, not just the visible growth, so it takes noticeably longer to return.

Mould and algae removal

Dark streaking and mould on shaded roof faces gets treated at the same time, restoring the roof's original colour underneath.

Gutter and valley clearing

We clear built-up debris, moss, and sludge from gutters and roof valleys, since blocked areas are usually where moisture damage starts.

Why Pressure Washing Can Do More Harm Than Good

A lot of homeowners reach for a high-pressure water blaster thinking it's the quickest fix, but on tiled roofs it can strip the protective granules and glaze straight off, and on coloursteel it can force water up under the laps and lift paint coatings. A soft-wash treats the moss and lichen chemically and rinses it away at low pressure, which gets the roof clean without damaging the surface underneath it, and it tends to keep the roof cleaner for longer as well.

The First Step Before Repainting or Coating

If your roof is heading for a repaint or a protective coating, cleaning always comes first. Paint and coatings don't bond properly to a roof that's still got moss, lichen, or grime sitting on it, so skipping this step means a shorter-lasting finish no matter how good the paint job is. We build cleaning into the front end of most repaint and coating jobs for exactly this reason.
