What are the Supply Costs of Roof Cleaning?
When it comes to having your roof cleaned, you won't usually need any supplies as the company you hire will usually have everything they need to complete the work.
In some cases, if your roof is quite large or difficult to access, then you may need to hire scaffolding so that the work can be completed.
The average cost of hiring scaffolding is around £600-700 as you will need to provide access to the entire roof. The cost will depend on the amount of scaffolding needed, your location in the UK, and the length of time you hire the scaffolding for.

The cost will depend on the size of your home, the type of guttering that you choose, and your location in the UK.
When you get your roof cleaned professionally, it will end up looking brand new. With this in mind, you may want to get the exterior walls of your home painted so that the home's entire aesthetic is improved.

Types of Roof Cleaning
There are several different types of roof cleaning methods. Below is a list of the most common roof cleaning methods in the UK:
Eco-Friendly Roof Tile Cleaning
Some of the harsh chemicals in traditional roof cleaners can damage the roof and may alter the colour of the roofing materials. With this in mind, many people now choose eco-friendly cleaning options.
However, the only problem with these cleaning options is that they are quite expensive.
Chlorine Bleach Roof Cleaning
Chemical roof cleaners aren't very expensive, and this method is also quite fast and easy. Usually, roof cleaners will spray chemicals such as trisodium phosphate and high concentrations of sodium hypochlorite on the roof.
Once this has dried, they will reapply it as needed. The only problem with these cleaners is that they can let off some fumes and may cause damage to plants and vegetation surrounding the home.
High-Pressure Power Washing
This is a very popular option for roof cleaning. This method can use either hot or cold water to clean the roof. This cleaning method cleans the roof surface; however, it doesn't always eliminate all of the organisms on the roof completely.
High-pressure power washing does not require any chemicals or detergents, so it is eco-friendly. This method is also affordable and can be used to treat ceramic tiles.
Cleaning moss off a roof involves scraping away all of the moss on the roof. Moss can retain moisture and cause damage to your roof; plus, it can be very unsightly.
Therefore, many people opt to have the moss removed from their roof. Once the moss has been removed, the roof will usually be cleaned afterwards to eliminate any dark spots that may have formed where the moss was.
Benefits of Professional Roof Cleaning
There are many benefits of professional roof cleaning. Below is a list of the main benefits of this type of work:
When you get your roof cleaned and treated, this can help to prevent damage to the roof. Leaving your roof dirty and untreated can lead to roof damage which can then lead to leaks.
The best way to prevent this from happening is to ensure that your roof is routinely cleaned and maintained.
Identify Roof Problems
When your roof cleaning contractor is up on the roof, they may identify some roofing issues. This can include things like broken roof tiles or potential leaks.
It's always best to identify these roof problems early to prevent them from getting any worse over time.
Identify Gutter Issues
Similar to roofing issues, your contractor may also be able to identify guttering issues. If guttering issues are identified early, then they can usually be repaired quite easily.
However, if the guttering is left damaged for too long, it may need to be completely replaced. So again, it is always best to get these issues identified early, and regular roof cleaning can help make that happen.
When your roof is dirty and full of moss, leaves and other debris, then it may start to look very unsightly. The best way to improve the look of your home is to get the roof regularly cleaned and remove all of the moss, dirt, and debris. Regular cleans can help to make your home look much more aesthetically pleasing.
Increases Roof Life
Regularly cleaning and maintaining your roof can help to increase the life of your roof. Leaving your roof dirty and full of moss and debris can damage and reduce the roof's lifespan.
This means that you should aim to get your roof cleaned at least once each year to keep it in good shape.
Q: Why do you need to remove moss from a roof?
A: Removing roof moss is needed to help to guarantee the proper functioning of the water drainage. If water remains on the roof, this can lead to damage – especially if the water freezes in the winter.
Q: How often should the roof be pressure washed?
A: It is recommended that you get roof and gutter cleaning done every 1-2 years. If the home is very dirty or if it's underneath a lot of trees and prone to debris, then you may need to get it cleaned more often.
Q: Is roof cleaning essential?
A: Yes, roof cleaning is essential. For most roof types, treatments and cleaning are required to avoid damage to the roof. Replacing a roof can be extremely expensive and is usually something that most homeowners want to prevent.
If you don't clean your roof, it can become susceptible to moss infestations, leading to clogged gutters, broken tiles, internal black mould, and many other issues. Cleaning your roof will help to make it last for as long as possible.
Q: Does moss have roots?
A: Roof moss has small, thin root-like growths that help anchor the plants to the surface of your roof. These growths can cause damage to roof tiles and can loosen the tiles.
These growths are also the reason why moss is so difficult to remove from the roof and why most people choose to hire professionals to complete the moss removal on their roof.
Q: Does pressure washing the roof cause damage?
A: This will depend on the type of roof that you have. However, there is a chance that pressure washing can cause some slight damage. Slate roof tiles can become dislodged by a pressure washer as the force of the water is very strong.
Q: How much is a conservatory roof cleaning?
A: Conservatory roof cleaning is actually quite cheap. You can expect to pay around £3-£6 per roof panel. This can help to clean off any dirt and debris from the roof that may cause damage down the line.
