Why We Offer a 12-Month Moss-Free Promise
At MMRCS, we believe a guarantee should be realistic, transparent and something we can genuinely stand behind.
You may see roof cleaning companies offering guarantees for several years. While that may sound appealing, we believe the length of a guarantee isn't the only thing that matters.
A roof is exposed to the weather every day. Rain, wind, shade, nearby trees, falling debris and the surrounding environment can all influence how quickly moss and organic growth return.
For that reason, we choose to offer a 12-Month Moss-Free Promise.
12 Months Guaranteed. Cleaner for Longer.
Our specialist biocide treatment continues working after your roof has been cleaned, helping to control remaining organic growth and reduce significant moss regrowth.
We guarantee your treated roof against significant moss regrowth for 12 months from the date of treatment.
But 12 months is our guarantee — not the expiry date of your clean.
Depending on the roof and its surrounding environment, the results can last considerably longer, with many roofs staying noticeably cleaner well beyond the guaranteed period.
Why Not Promise Several Years?
We don't believe it would be responsible to promise that every roof will remain moss-free for a fixed number of years.
Every roof is different.
A roof surrounded by trees and shade will naturally be exposed to very different conditions from a roof in an open, sunny position. These factors can affect how quickly organic growth returns.
Our 12-month promise gives you a clear period of protection that we are confident we can stand behind, without making exaggerated promises about something that is influenced by the environment.
What Happens If Moss Returns?
If significant moss regrowth occurs within 12 months of your roof being cleaned and treated, simply contact us.
We'll assess the affected area and, where the guarantee applies, return and retreat the affected areas free of charge.
No hassle. No hidden costs.
Our Approach
We don't want to simply make your roof look clean on the day.
Our aim is to:
Remove existing moss and organic growth
Use the appropriate cleaning method for your roof
Apply a specialist biocide treatment
Help keep the roof cleaner for longer
Provide a realistic guarantee that gives you genuine peace of mind.
We'd rather offer a realistic 12-month promise and exceed your expectations than make a bigger promise that doesn't reflect the reality of roof cleaning.
12 months guaranteed. Cleaner for longer.
