Roof Maintenance Plan across Devon
Once a roof has been cleaned, the best way to protect that result is to stop the growth coming back. Our roof maintenance plan applies a light biocide treatment every 2–3 years — no repeat full cleans, no scaffolding, just a simple regular visit that keeps moss and algae from re-establishing.

The Moore & Franks approach
Biological growth is airborne, so some regrowth is inevitable on any roof — north-facing and tree-shaded roofs fastest. A periodic biocide treatment keeps it in check for a fraction of the cost of letting it return and cleaning from scratch again.
We'll recommend the right interval for your roof and aspect, and simply book you in when it's due so you never have to think about it.
A clear, repeatable process.
No surprises, no upsells. The same method every job — that's how you get the same result every time.
