Moss, lichen or algae
Organic growth is spreading across visible roof areas or collecting where the roof stays damp.
Roof Cleaning & Biocide Treatment in Kilmore
Moss, lichen, algae and airborne grime can make roofing look tired and hold moisture against the surface. We provide considered roof-cleaning options for suitable tile and Colorbond roofs.
When roof cleaning may be worth considering.
These are some of the common signs that it may be time to assess the surface and recommend an appropriate approach.
Dark or uneven areas
The roof is developing noticeable discolouration, streaking or a generally weathered appearance.
A planned maintenance need
The colorbond roofing or concrete roof tiles needs assessment before growth becomes more established.
Our three-step plan.
A considered process built around your home and its different exterior surfaces.
Assess and plan
We identify the colorbond roofing, concrete roof tiles, terracotta tiles where suitable, condition, access points and sensitive areas. Where relevant, manufacturer care guidance is checked before the cleaning plan is confirmed.
Set expectations and complete the work
Roof access, pitch, material, coating condition, water tanks and drainage are assessed first. The method may involve soft washing, targeted organic growth treatment or a biocide application that works over time. Colorbond, concrete tile and terracotta each require different limits and precautions. Rainwater tank lines are isolated where required, and runoff is managed as part of the job plan.
Final walkthrough
We inspect the finished areas, tidy the work zone and walk through the result with you. Any questions or areas needing attention are addressed before the job is considered complete.
Good to know.
Do you pressure wash every roof?+
No. Soft washing or a biocide treatment is often more suitable. We select the method after assessing the roof material and condition.
What is a biocide treatment?+
It is a targeted treatment for biological growth that can continue working after application. Results and timing vary with the roof and weather.
What happens if I have rainwater tanks?+
Tank connections and runoff must be considered before roof cleaning. We discuss the necessary isolation and reconnection steps during the quote.
How should I prepare for roof cleaning?+
We explain any property-specific preparation during quoting. This may include clearing access, moving fragile items, closing windows or isolating water systems, depending on the service.
Can roof cleaning be combined with other exterior services?+
Yes. Compatible services can be included in one quotation when access, timing and surface conditions make a coordinated visit practical.
