Roof Cleaning – Your Questions Answered
How often should I clean my roof?
We recommend cleaning every 3–5 years, depending on moss growth and local climate.
Will roof cleaning damage tiles?
Our process is gentle but thorough, with zero risk to your roof surface.
Can it help with insulation or energy bills?
Clean roofs reflect more sunlight and stay cooler in summer, which can reduce energy usage.
What does biocide actually do?
Without biocide, new moss returns faster. We highly recommend it.
