Roof Cleaning

 
How do you clean moss from a roof? Cotec roof cleaners use two systems Low Pressure Wash or Softwash Roof Cleaning. The unit we use for roof cleaning is set at a lower pressure than your standard pressure washer as all we need is the dirt and moss removed from the roof. The inhibitor treatment will kill any residual biofilm and continue to clean the roof for the follow 12 months. There are certain roof tiles (Rosemary Clay Fibre Cement) that do not benefit from low pressure cleaning so for these roof tiles we would recommend softwashing but we would advise which is the best solution to clean the property roof. Low Pressure Wash Roof Cleaning: Pros: Same day clean-night and day results Cons: Messy Job and there is always the chance of a water leak. Softwashing is scraping the roof removing the bulk of the moss before applying a premium inhibitor treatment some roof can be treated with a cleaner if a quicker result is required. Softwash Roof Cleaning: Pros: The works are not as messy as pressure washing. There is no chance of water leaks Cons: The product can take up to 1 year to work. Roof only look a little better on the day of the clean.

Low Pressure Roof Cleaning:

Cleaning is carried out in two stages: 1) The roof is washed using our low pressure jet wash which removes the bulk of visible dirt lichen and moss. The roof is then rinsed of all debris before the next step. 2) The second stage is the application of a premium inhibitor (residual cleaning properties) at the correct dilution rate according to the manufactures instructions killing any residual spores. The application of the inhibitor is essential as it will slow the regrowth of moss lichen etc a reasonable expectation is that the roof surface will be biofilm free for 18-36 months before a second treatment is required.

Roof Cleaning the Works Sequence

Arrival on Site

This is normally 8am. We will contact you a few days prior to our arrival. The weather can delay roof cleaning but we would always advise you if we could not start works. Works can last up to 3 days depending on the roof size.
Low Pressure Wash The roof is washed from the top down. The work is never rushed. Once the roof is free of moss it is rinsed.
Happing Up The property is happed up to protect the customer garden and catch the moss. Down pipe filters are also fitted. It may necessary to hap your neighbours garden depending on the proximity to your property. Roof cleaning can be a messy job so all garden furniture plant pots etc. should be moved away from the house. It is advisable to move any cars from the driveway (neighbours may need to move their cars) It is always wise to advise neighbours of the proposed works.
The Clean Up Gutters are cleaned out and filters removed. The moss is collected into bins for removal off site. The building is rinsed down from the top facia soffits wall windows doors removing any overspill. The ground area is also rinsed leaving the area clean and tidy
Moss Inhibitor The final stage of the works is to apply a premium moss inhibitor which will kill off any remaining spores and prevent regrowth for up to 36 months.

Softwash Roof Cleaning

This system can take up to 1 year to fully clean the roof but results should be seen within a few months. We use a professional concentrated cleaner for removing natural growths such as moss spores algae or mould from roof tile surfaces. Benefits: Does not require rinsing. Treats roof tile surface with no risk of staining and damage Contains no acids or bleach Can also have some residual benefits.

The moss is normally always cleaned from the gutter level with telescopic tools unless scaffold is erected. The downpipes are protected against blockage beforehand. Tarpaulin is laid to receive the falling debris and gutters are cleaned out before the biocide is applied.
The roof is scraped from the gutter level using special tools. The bulk of the moss is removed from the roof but small moss particles and white lichen will still be obvious at the end of the cleaning process. However, the biocide treatment will do the work killing the biofilm over time. The roof will self-cleanse but this varies with numerous environmental factors.

I have used Cotec twice now over the past 6 years and cannot recommend them highly enough. They undertake the work to a very high standard and the clean up operation was exceptional. Sam even came back at a later date with a replacement tile that he had discovered to repair a slightly cracked one in my roof. There are a number of companies advertising similar services but I would be surprised if anyone can match this standard. All work completed as per the Statement of Work, on time and at the agreed price. I will certainly be using them again in two years time when the roof needs cleaning.

The roof should be treated with inhibitor at least every 3 years in order for the roof to remain biofilm free. The failure to maintain the roof will result in the return of moss and lichen
