Our Roof Cleaning Process
Scraping and treating
When being on the roof, we place a roofing ladder on the roof to work from and in some occasions, we will use a cherry picker, depending on the type of tile, shape and the condition of the roof.
Depending on how bad the moss has covered the roof and the condition of the tiles, sometimes we start by applying a dose of biocide (if it is needed) 5-10 days before we start, to begin killing the moss. This makes it easier to remove the moss and reduce the risk of damages.
When we come back to start the job, we first start by blocking off all the guttering downpipes and laying down catch mats to catch falling moss to make cleaning up easier.
We then start by removing the moss with long telescopic tools so we move as little as possible to reduce the chance of causing any damage to the tiles. We will either access the roof by cat ladder and scrape from the roof or work from a scaffold tower.
When all the moss is removed we clean the gutters out, making sure there is nothing left in the gutters. When the roof is dry and free of moss, we apply another coat of biocide to the entire roof. This will kill the roots and spores of any moss or algae and start to kill any lichen on the roof.
This is a long term cleaning process that starts working within a few weeks and carries on cleaning over a few months. The moss spores, Algae and lichen are killed from the biocide and are naturally washed off with heavy rains and weathering over time.
This kills the roots of the moss but visually cleans your roof over the case of a few months. We recommend 1 more treatment of biocide after 9 months to a year after cleaning the roof to prevent the re-growth of moss, keeping your roof looking good for as long as possible.
A Softwash roof clean is the safest way to clean your roof with an instant result. Soft washing does not run any risk of shooting water into your loft space or stripping the coating of the tiles.
You cannot always see the total condition of a roof or the felt that lays underneath the tiles. It also does not run any risk of blowing the cement out of your ridge tiles or damaging what is already blown. There is a lot of cowboys out there that will clean your roof with too much pressure, blow the cement out of the ridge and then sell you a new ridge when it could have been prevented!
The cleaning process itself consists of either accessing the roof with a cat ladder or working off a scaffold tower at guttering height. We cover or disconnect all the downpipes to prevent blockages and manually scrape all the moss from your roof.
When the moss has been scraped off and the gutters have been emptied we apply a cleaning solution to the roof, soaking it and leaving it to dwell for 30 minutes – 60 minutes depending on the temperatures. Sometimes on badly covered roofs, we will agitate the area with a telescopic brush or water fed pole that applies the solution at the same time to help get into the deep staining.
This can be applied 2-3 times depending on how bad the algae build up is. After this process, the roof is then rinsed down with clean water. The cleaning solution will kill any algae and moss spores and start to kill any lichen.
The lichen may not be removed fully on the day because they hold a very tight grip to the tiles and mortar, but they will die and turn white. An after treatment is applied to the entire roof and this will continue to kill any remaining algae and lichen spores and stays active on the roof for multiple months to make sure no new growths start and it will continue to clean your roof over the next few months.
The lichen takes slightly longer to disappear completely. It can take up to a few months, sometimes longer in certain situations but they disappear with high rain and natural weathering as they die and flake away. After cleaning the roof may be left with white spots but that just means the lichen are dead and over time your roof will self-clean and be spotless. This is the preferred way to clean most roofs because of the minimal risk of causing any damage and getting a great result.
On a lot of roofs they can be cleaned without even taking a step on a single tile but occasionally it does make life a lot easier to work off the roof if it is safe to do so.
Low pressure roof cleaning
A low-pressure roof clean is a cheaper solution to ‘soft washing’, When carrying out a low-pressure roof clean it would preferably be on a roof that is in a reasonably good condition.
We start by blocking all the guttering downpipes and accessing the roof with a cat ladder or cherry picker, working off the ladder or out of the cherry picker basket.
The process consists of rinsing the roof down with low pressure, removing the moss, algae and lichen that is growing on there, bringing back the underlying colour of the tiles instead of seeing the dark dirty coloured surface they usually are. sometimes we will apply a cleaning solution before starting if we think the roof may need it.
A low pressure clean is an instant finish so you don’t have to wait for results. This is a very common way of cleaning roofs and very effective if you know what you are doing.
When the roof is fully cleaned and well rinsed we apply a biocide to kill the spores and roots from the algae making sure it does not grow back. Cleaning a roof with low pressure is like pulling up a weed, it’s gone but if you don’t kill the roots, there’s a very good chance it will come back. An after treatment is advised.
When we are done, a full clean down of all the gutters and overspray of dirt and moss is cleaned up, leaving your property looking amazing!
