Frequently asked questions
Is moss on my roof really a problem?
Yes. Moss retains moisture against tiles, causing freeze-thaw cracking in winter. It also washes into gutters during rain, blocking them within months. Treatment now prevents expensive tile replacement later.
Do you pressure wash the roof?
We use low-pressure soft-wash methods — high-pressure washing damages tile surfaces and voids manufacturer warranties. Our biocide approach is more thorough and longer-lasting.
How long before the moss dies?
The biocide kills moss within 2–4 weeks. It then dries out and washes away naturally. We can arrange a follow-up mechanical scrape 6 weeks later for faster visual results.
