Frequently Asked Questions

When is the best time of year to have my roof cleaned? +

There is not a best time of the year to have your roofing cleaned. Roof cleans scheduled in the winter months can occasionally be rescheduled due to bad weather such as Ice, Snow or High Winds. We work in all other weather as we strive to provide a reliable, all year round service.

Do you softwash roofs? +

No. Softwash is a method of cleaning using Sodium Hypochlorite (Bleach). The only chemical we use is Biocide, which is safer than Bleach. Biocide does not produce harmful fumes like Bleach, it is also a lower toxicity.

Does Biocide Treatment Remove Lichin? +

Yes. Biocide will kill Lichen and all other organisms that it comes into contact with. Lichen is gradually removed from all porous roofing materials through the natural weathering process. There are over 20,000 species of Litchin, some of which can take 2 applications of Biocide (3 years apart) to completely remove.

How long does the roof treatment last? +

3-5 years. Biocide roof treatment continues to inhibit the growth of moss for 3 - 5 years following application.

Do you repair roofs? +

No, we do not provide roofing repairs. We strive to be the most professional, reliable roof cleaning service, for that reason we stick to our speciality. We recommend using TrustaTrader or Checkatrade to find a local roofing contractor for roof repairs.

Are you licensed waste carriers? +

Yes. We are licensed by the Environment Agency. Our waste carriers license allows us to legally transport waste removed from roofing to a licenced waste disposal centre.

Roof cleaning carried out safely from scaffold towers by The Roof Moss Cleaners in London Colney

The roof now looks amazing

"We have lived in our house for 30 years and replaced the roof when we bought it; parts of the house are over 200 years old.

This is the first time that the roof has been properly cleaned and a lot of moss had built up over the years. It was blocking gutters and generally making a lot of mess.

The team of guys did the whole job in one day with the help of cherry pickers and scaffolding and they were here for a good 10 hours from start to finish. The roof now looks amazing and I keep going outside to look at it. I am told it will get even better over the next few months as the treatment takes effect.

A very thorough job of cleaning up afterwards as well. The communication process from start to finish was excellent and all my questions were patiently dealt with! Thank you and I am very pleased indeed with the job. Highly recommended."

Roof cleaned by The Roof Moss Cleaners with all moss safely removed

Turned up bang on time

“We have recently moved into our 40 year old bungalow, and right from the word go decided that the roof needed a proper clean up.

Contacted The Roof Moss Cleaners and their quote seemed very reasonable. Arranged the date and they turned up bang on time.

They have done a fantastic job and we are more than pleased. They cleaned up after themselves. They must have been with us for around 7 hours.

Thank you very much.”

Final result after safe roof cleaning with no tile-walking

Cost of the job was very reasonable

“This company recently cleaned our roof. After scraping off all the moss they sprayed the roof with a biocide treatment, which guarantees the moss will totally disappear and not return for some time. Some broken roof tiles were also replaced and now the whole roof is looking fantastic.

All the guys in the team were hard working and professional. The cost of the job was very reasonable and we highly recommend RMC.”

manually removed moss from redland concrete tiles - before and after

Excellent job of removing many years of moss growth

“The RMC did an excellent job of removing many years of moss growth from our (relatively large) roof.

The team (Ant and Gaz and Harry) arrived when they promised, worked very hard at cleaning and then treating our roof - and cleaned up well afterwards.

The appearance of the roof is much improved and I am looking forward to not having to clear our gutters every few months. Good job !”
