MMRCS 12-Month Roof Cleaning Promise
Professional Standards. Targeted Protection.
At MMRCS, we stand by our methods and the effectiveness of our treatments. Whether you choose our Manual Scrape & Biocide or Low-Pressure Roof Wash, your property is covered by our 12-Month Moss-Free Promise.
What Is Covered
Moss Prevention & Treatment
Following a manual scrape, it is normal for a small percentage of organic matter to remain within the laps and fixings of the tiles. Our professional-grade biocide is applied to treat this remaining organic growth and continues working after the initial clean.
We guarantee your treated roof against significant moss regrowth for 12 months from the date of treatment.
12 months is our guaranteed period, not a limit on how long your roof can stay cleaner. Depending on the roof and its surrounding environment, our treatment can help keep your roof noticeably cleaner for considerably longer.
Low-Pressure Roof Washing
We use specialist low-pressure equipment designed specifically for roof tiles. We guarantee that our washing process will not damage the structural integrity of your tiles or cause unnecessary wear to the tile surface when carried out as part of our recommended cleaning method.
Manual Scrape & Surface Integrity
Our manual roof cleaning process is carried out using methods designed to minimise unnecessary stress on the tiles. If any aspect of our workmanship results in a dislodged tile or blocked guttering during the cleaning process, we will return to site and rectify the issue at no cost.
Post-Clean Gutter Check
As part of every roof clean, we ensure that gutters are clear of cleaning debris and functioning correctly before we leave your property.
What Happens If Moss Returns?
If significant moss regrowth occurs within 12 months of your treatment, contact us and we will inspect the affected area. Where the guarantee applies, we will return and retreat the affected areas free of charge — no hassle, no hidden costs.
Terms and Conditions apply.
Terms & Conditions
To ensure the 12-month promise remains valid, the following conditions apply:
1. Overhanging Trees & Foliage (Guarantee Exception)
Organic matter from overhanging trees (such as leaves, needles, and sap) is the leading cause of premature moss return. If a roof is situated directly under or near heavy tree cover, the constant drop of organic debris provides a "bridge" for new spores to grow, which can bypass the biocide’s effectiveness.
- Please Note: Due to these external factors, we are unable to provide a 12-month regrowth guarantee for any roof areas situated directly under or within 5 metres of overhanging branches and heavy foliage.
- To qualify for the full 12-month promise, we recommend that all branches are trimmed back at least 5 metres from the roofline prior to our treatment.
- Solution: For properties with heavy tree cover, we recommend our Roof Care Plan. This provides regular maintenance and biocide top-ups to ensure your roof stays clean despite the surrounding environment.
2. Notification
In the unlikely event that you see significant new moss returning within the first year (on sections not affected by overhanging trees), please contact us with a photo. We will return to inspect and provide a complimentary biocide "top-up" to the affected area if required.
3. External Damage
This promise covers our workmanship and chemical effectiveness only. It does not cover damage caused by extreme weather (storm damage), structural failure of the roof, or third-party tradespeople walking on the tiles.
4. Site Access
MMRCS must be granted safe access to the property to carry out any required inspection or remedial work.
