Many people think that any pressureised water on your roof will lead to leaking, but this isnt the case, gentle pressure can clean all the moss, algae andf lichen off your roof leaving it clean and fresh ready for a protective biocide treatment.
We start by carrying out a brief survey of the roof to inspect for any damage before starting any work, this gives both us and the customer peace of mind for the roof clean.
Once we have chosen a date for your roof clean we will first build our access tower, in most cases, we don’t want to be on the roof at all.
Any pressure on your roof at the wrong angle can lead to broken tiles so the majority of our work is carried out from a 9.5m access tower. Sometimes we do have to go onto the roof with a CAT ladder if a particular section is inaccessible.
This type of ladder gives the most protection to your roof by utilising multiple points of contact and is designed for this purpose.
Now to the actual cleaning, we use a tailor-made set of roof scraping blades designed by manufacturers to fit nearly all makes of tile that we see on homes today.
Using these custom-fit blades we scrape the roof tiles free of any large pockets of moss, some small flakes off moss will remain but these will be dealt with by the biocidal treatment.
Once to roof has been scraped of any large moss and lichen deposits we move onto the Biocide treatment.
We do use different treatments depending on the type of tile and the main colonisation(moss, lichen etc)
Our treatments are applied with a flocked soft bristle water fed brush giving us maximum control over where the chemical gets applied.
We start at the bottom of the roof and work our way up to prevent streaking and ensure even coverage of biocide.
