Is Roof cleaning necessary?
If you look around your local areas you will find 80-90% of homes roofs are covered in unsightly moss and algae.
Not only does this look unpleasant to the eye heavy moss growth on the roof can cause damage to your roof over time.
The moss acts like a sponge soaking up the moisture in the air and rainwater.
When the moss then freezes, it expands on the surface which can then lead to cracking in your roofs pointing, lifting of tiles. We have also seen moss eat its way into tiles leading to the surface becoming defaced.
How do you clean a roof?
The most common ways to clean a roof are either by pressure washing the roof or a gentler approach is soft washing the roof.
Pressure washing the roof is carried out via accessing the roof by either using access equipment such as a MEWP (cherry picker) or using rope access and roofing ladders. If the roof is fully accessible some pressure washing the roof can be carried out from a portable scaffold tower and telescopic lances.
Roof Moss removal also know as Soft washing the roof is a way of cleaning the roof without the need for a pressure washer. Again, this is done either via a portable scaffold tower and telescopic roof scraping tools or from gaining access to the roof via a roofing ladder and securing the operator using fall arrest equipment. The bulk of moss is manual removed followed by a moss and algae treatment then applied to kill any remaining moss/algae which in turn results in a cleaner roof over a period of time.
What chemicals are used to clean roofs?
The main chemicals used to clean a roof are sodium hypochlorite based products which give instant results.
The sodium hypochlorite based products are usually sprayed on the roof after the moss has been removed and then washed off as it is not recommended to leave this product on the roof.
Another chemical used is a biocide treatment (DDAC) which is applied to the tiles but instead of being rinsed off this is then left on to work over a period of time with the natural weather cycles.
How often should you clean your roof?
Once your roof has been cleaned if an application of biocide has been applied after the clean the roof should stay clean for an average of 3-5 years. This time scale depends on the property’s environment as a more rural home is more likely to show signs of regrowth faster than a townhouse.
To keep the roof cleaner for longer maintenance treatment can be applied once the roof is showing signs of regrowth which will then keep the roof cleaner for many years to come.
Does cleaning your roof damage it?
This is a question that gets asked a lot, many people are under the allusion that cleaning your roof will damage the roof tiles taking of a “protective coating”.
An aged concrete roof will already have lost the coloured surface of the tile with the UK’s harsh weather cycles and this is why you find when aged concrete roofs are cleaned they all end up the same colour.
Using the correct pressure and nozzle along with using a professional roof cleaning company either the soft wash or pressure washing cleaning option will not cause damage to your roof.
We made a little video to show 5 of the most popular roof tiles on UK homes both before and after being pressure washed
As you can see in the video using the correct pressure the roof tiles were not damaged at all.
Soft washing the roof is even less harsh as the whole roof cleaning process is carried out using no pressure whatsoever. The moss is removed by handheld tools and the treatment are applied via low-pressure sprayers.
How much does it cost to have a roof cleaned?
Every roof is different and there are many factors to take into account when pricing a roof clean.
When a company comes to quote your roof clean will take into consideration the size of the roof, the amount of moss present on the tiles, access to the roof, tile type and so on.
So, it’s not just as easy as saying roof cleaning cost X amount.
A guide price for your roof to be cleaned via pressure washing after speaking with many roof cleaning company’s across the UK we found vary from £8-15 per sq.m.
To receive an accurate quote a professional roof cleaning company would need to visit the property so they can fully see the roofs access, soiling, size etc…
How much does it cost to remove moss from a roof?
Soft washing or removing the moss from a roof is usually a cheaper option than pressure washing.
The thing you need to ensure when having your roof soft washed is to find out exactly what product the company will be applying to your roof to after the moss has been removed.
The biocide treatment is what will kill all biofilm and protect your roof from any new regrowth so using a top-quality treatment is essential to ensure you get the best results possible.
The average price for roof moss removal and soft washing a roof we found to be in between the price range of £5-12 per sq.m so on some occasions can be half the price of pressure washing a roof.

This week we got called out to a roof that was leaking into the customers home and causing damp issues within her bedroom and bathroom. Below you can see some photos taken before and after we carried out the repairs.
Upon arrival the team carried out a full roof survey which bought not only 1 problem to light but THREE!!
Problem 1: The ridge tiles has either little or no pointing at all allowing water to seep through the gaps and into the customers home.
Problem 2: Loose and slipped tiles which meant there were areas where no tiles were sat at all again allowing water to leak through.
Problem 3: The roof tile under felt was severely perished at the gutter line which meant any water that should have been flowing off the roof and into the gutters was actually leaking through the porous felt and straight into the customers bedroom.
So after photographing all of the problems to show the customer and talking her through the problems along with ways to resolve these issues, she decided to get the repairs carried out straight way. The lads soon got to work re-bedding the ridge tiles
Ridge Tiles Re-Bedded & Re-Pointed
Also fitting felt support trays to allow any water to run straight into the gutters as it should if for any reason water did manage to get under the tiles in the future.

When moss is removed from a slate roof it will dramatically improve the look of your house, it gives a great first impression to the rest of your home. When moss and lichens are left on the slate it will over time become porous, holding onto moisture and look and feel less smooth.
The way a slate tile roof should be cleaned depends entirely on the debris build up. The roof videoed below was prepared by removing the bulk of the debris and moss by hand using a handheld scraping tool and then a non aggressive treatment was applied to the tiles which begins to work immediately in killing the biofilm.
The treatment will continue to work over a period of time with the weather giving it a helping hand, these results aren't seen immediately but once they've started working in removing the biofilm the tiles will start to self cleanse. The bonus with this approach is not only is it a lot less harsh on the roof tiles but it also offers protection from re growth for many years to come.
Why should I remove the moss from my slate tiled roof?
Cleaning your roof regular is very important to keep your slate roof in good working order. When moss builds up it acts like a sponge holding onto moisture which can easily lead to the tiles splitting during the winter months when it freezes over.
Slate is a sedimentary rock with minuscule layers that easily split. This quality is what distinguishes slate as a suitable roofing material. Once turned into roofing material, slate absorbs water and can naturally de-laminate during the freeze-and-thaw cycles of winter.
A slate roof should last a lifetime, flashing and fasteners etc are often the highest quality so they don't fail before the slates need replacing.
So the team today were over in Coven, Wolverhampton pressure washing these Marley Bold Roll roofing tiles.
The customer had recently had an extension and wasn’t happy with the dramatic difference between his old tiles and the new tiles on his extension.
After talking through a few options the customer decided that pressure washing the original tiles was the route he wanted to take (as here at Brightroof we offer a number of roofing cleaning alternatives to pressure washing roofs).
As you can see from the before photo above, the original roof tiles were heavily covered in moss and algae making the roof looking very unsightly compared to the newly laid roofing tiles .
On arrival, the team got to work covering the customer’s lawn and driveway to ensure all debris was to land on our sheeting minimising any mess and guttering was then disconnected making sure no blockages occurred during the cleaning process.
Once the roof has been pressure washed and the whole area was cleaned, the last part of the process was to apply a treatment to the tiles to prolong any regrowth of moss or algae keeping the roof cleaner for a longer period of time.
As I'm sure you will agree the results look phenomenal and as you can imagine the customer was over the moon with his clean roof.

Is Moss On Roof Harmful ? The short and simple answer here is yes, roof moss can be a serious and costly problem and here are just a handful of reasons why:
Moss growing on your roof can and will over time cause severe damage both internally and externally to your home and once it takes hold, it holds on tightly and accumulates quickly, it takes hold on a roof by extending rhizoids, which are strong root-like tendrils that keep it from blowing off or washing away in the rain.
External damage includes tile damage as the moss gradulally lifts the tiles creating cracks and crevices that allow moisture to get underneath them. This can ultimately cause roof leaks and rotting of the wood underneath. Moss also eats away at the tiles surface which again results in weak, porous and cracked tiles, it can grow in and around your roof tiles and actually starts to acts as a ‘filler’, packing out any gaps and plugging the spaces, thus meaning your roof will no longer be water tight.
It will damage your guttering as the moss will be falling off of the roof and into the gutters, weighing them down, which in time will cause them to snap or crack and will also block them meaning water won’t have the escape route it needs to be leaving your roof so will sit against the roof tiles and lead to damp within the home.
Moss also grows in blankets and absorbs large amounts of water like a sponge, resulting in your roof tiles constantly being wet, this again will cause damp within the home.
Moss will grow in areas that are particularly moist, dark and cool.
If you come across a patch of moss that has turned brown or black, Don’t ever be fooled into thinking that the moss is dead if you were to add a little water you might be surprised. Many times the plant will turn green and begin thriving again once moisture is reintroduced!
Trying to deal with a roof moss problem on your own can be fruitless and even dangerous—mossy roofs are slippery roofs! Call Bright Roof today and one of our team can visit your property and advise the best method to tackle your moss covered roof.
ensure the roof was in good repair, preventing any leaks into the home, this is standard protocol for the team at Bright Roof.
Our customer mentioned that she had recently had some roof tiles re-bedded and tiles replaced, once our team were on the roof we could see the roof work the customer had mentioned, unfortunately, the roof tiles hadn't been re-bedded as the customer thought, but in fact they had been pointed/skimmed and tiles "repaired" which should have just been replaced, so if we started the roof clean the roof would've started leaking.
The customer chose to have her roof jet washed, of course before this work could commence we carried out the relevant roof repairs to ensure there would be no leaks or damage to the roof.
The team soon got to work re-bedding all of the customers ridge tiles and replaced the bodged tiles that the previous roofer had tried to repair.
Once all of the necessary roof repairs had been completed the team were then able to get to work cleaning the roof, using the correct nozzles and water flow, we were able to pressure wash the roof without causing any damage to the tiles and still able to remove all of the moss, algae and lichens from the tiles.
As you can see from the photos there is a dramatic difference in which the clean has made to the property.
I'm sure you can guess the customer was over the moon with the results we achieved.
Today the team at Bright Roof were over in Shrewsbury pressure washing a customers bungalow roof.
The picture on the left shows how heavily soiled the roof was in moss.
The customer had noticed the moss falling into their gutters making them blocked and also dropping onto the floor around the house which made the property look untidy, not to mention the customer regularly having to go out and clean up the moss deposits from the floor.
Prior to carrying out the jet washing on the roof, our team visited the property earlier on in the week to do a full roof inspection and carry out any roof repairs necessary before the work went underway. We always ensure a roof is in good repair before roof cleaning is carried out to eliminate the risk of leaks within the home/property.
All repairs were complete and left to set before the team returned.
When the team returned to carry out the roof clean they covered all gutters to keep them free from debris during the clean. Also the customer and the neighbour was asked to move their car from the drive to prevent getting covered in debris from the roof.
Once the team were harnessed onto the roof the clean was started. Health and Safety is always key and first on the list with our team at Bright Roof.
As you can see and i'm sure you'll agree from the small amount that had been cleaned in the photo above that the transformation was already starting to look phenomenal.
still go around and check each gutter just incase any debris did manage to get into them, they would all be cleaned out and emptied.
We ensure the property is clear of all debris and muck and there is no trace of us being there other than the clean roof which as you can see on the photo below, looks like brand new.
