Roofs in Hamilton endure a lot. From torrential winter rain to intense UV exposure in summer, roofing materials degrade quickly if not maintained. Common problems include:
- Moss and lichen damaging tiles or lifting shingles
- Blocked gutters from roof debris causing overflow
- Water leaks and costly repairs
- Reduced lifespan of roofing materials
- Diminished curb appeal and resale value
With the right soft wash roof cleaning method, we can safely remove these threats without causing damage to paint, flashing, or tiles.
Trouble Spots by Suburb: Where Moss & Lichen Thrive
Some Hamilton suburbs are more prone to roof issues due to surrounding vegetation, wind exposure, and shade. Here’s a breakdown:
Hillcrest, Silverdale & Hamilton East
Shaded by mature trees and close to the river, these areas are especially vulnerable to moss and mould. Our treatments target biological growth deeply and safely.
Dinsdale, Nawton & Grandview Heights
Western-facing homes receive afternoon sun but collect grime and pollen from prevailing winds. A gentle wash removes this build-up without harming painted roofs.
Rototuna, Huntington & Flagstaff
Newer homes often feature dark-coloured roofs that show lichen clearly. We remove stains and protect finishes with low-pressure cleaning and moss treatment.
Glenview, Bader & Melville
Suburbs near SH1 experience dust and grit from high traffic. This grit embeds in porous roofing and attracts moss. Our cleaning penetrates surface texture for long-lasting results.
Our Roof Cleaning Process
At Metro Water Blasting, we tailor our roof cleaning methods to your roof type, age, and condition. Our process includes:
- Inspection – We assess roof material (tile, metal, shingle), pitch, and any areas of active growth.
- Treatment Application – We apply a biodegradable moss, mould, and lichen killer that breaks down growth at the root.
- Soft Wash Rinse – Low-pressure washing removes dead debris without damaging flashing, seals, or coatings.
- Gutter Check – We remove roof runoff and debris to prevent blocked downpipes post-cleaning.
All technicians are safety-trained and equipped for high-access jobs across all Hamilton suburbs.
How Often Should You Clean Your Roof?
We recommend:
- Every 12 months for high-moss areas (e.g. Hillcrest, Hamilton East)
- Every 18–24 months for sun-exposed roofs in Flagstaff or Huntington
- Before selling to boost street appeal and pass inspections
