What is Roof Cleaning? - Is Roof Cleaning Necessary?


What is Roof Cleaning?


Roof cleaning is an essential part of property maintenance. Cleaning a roof allows you to remove organic and inorganic substances from the tiles or shingles and check the surface for any damage. Keeping a roof clean not only helps to improve its aesthetic appearance, but can also extend its lifespan. This means that cleaning your roof regularly could actually save you time and money in the long run.

If you manage a large commercial or residential building, roof cleaning should be part of your regular maintenance schedule. If you haven’t yet invested in a deep roof cleaning, here are some more reasons why roof cleaning should be an essential part of your cleaning calendar.


How does Roof Cleaning work?


There are several methods professionals use to remove staining, discolouration, and organic substances from a roof's surface. Most roof cleaning and restoration works involve a biocide treatment to kill any moss, mould, algae or fungus present on the surface. Jets of water or steam are then used to remove any residue and leave the tiles or shingle looking new.

Our teams often choose to carry out roof cleaning without pressure washing. Using high pressured jets of water can actually damage the tiles and shingle and leave a roof in worse condition than when cleaning began. Using specialist roof cleaning methods and low-pressure water allows our teams to thoroughly clean a roof without risking any damage to the surface. Read more about softwashing Here.


Is Roof Cleaning necessary?


The roof is one of the most important parts of any building. There to provide a waterproof hat for the property, it’s exposed to the elements 24/7 and so goes through more than its fair share of wear and tear. Over the years, a lot of debris can build up on the surface of a roof. Roofs that are often damp or in the shade are prone to algae, mould and moss, while those in city centres often experience discolouration caused by atmospheric pollutants.

Removing this staining and discolouration from the surface of a roof can dramatically affect its aesthetic appearance. For many commercial and residential property management companies, this aspect of roof cleaning will be crucial.

As well as improving the aesthetics of a building, roof cleaning can extend its lifespan. A lot of organic substances will degrade the surface of the roof over time. Organic matter can cause wood to rot and tiles and shingles to become brittle. Roof cleaning for moss, algae, mildew and moss helps to prevent this degradation and extend the lifespan of your roof.

Finally, while carrying out roof cleaning for mildew, algae, moss and other contaminants, professionals can check the overall condition of the roof. This often results in small faults being identified early, which can prevent small issues from becoming more serious and save the client a lot of time, money and inconvenience in the long run.


What organic matter can build up on your roof?


Almost all roofs will experience a build-up of organic matter over time. Removing this organic matter is an essential part of roof maintenance. The three most common types of organic matter that roofs collect are moss, mould and algae. These appear most often on roofs that are wet for extended periods of time and on areas of a roof in the shade for most of the day.


- Roof cleaning for algae


Algae spores are carried through the air and deposited on external surfaces. In damp conditions, they can grow quickly, covering roofs in green, red or black patches. If algae aren’t removed properly, they will return again and again. To prevent this, we use a combination of powerful cleaning methods, including a specially selected biocide treatment.


- Roof cleaning for moss


Excessive moss growth can cause a real roof cleaning and gutter cleaning issue. When moss is dislodged from a roof, it can get stuck in the building’s guttering system and result in a blockage. If this isn’t dealt with, it can cause water to overflow and enter the property.


- Roof cleaning for mould


Mould growth is very common, especially on roofs that are wet for long periods of time. Like moss and algae, mould growth is treated with strong biocides before the roof surface is washed and cleaned.


What can roof cleaning be used for? 


You can use shingle and tile roof cleaning to improve the roofs aesthetic appearance and increase its lifespan. Roof cleaning from the ground and cleaning from ropes and mobile elevated work platforms (MEWPs) can remove a wide variety of staining, discolouration and organic compounds to leave a roof looking like new.


How does Spectrum clean roofs with no pressure?


As high-pressure jets can damage a roof's surface and cause water to enter a building, our operatives generally use low or no pressure water. By combining no pressure roof cleaning with strong biocides, we’re able to remove virtually all organic and inorganic matter from the surface of the roof.


Why use Spectrum to clean your roofs?


Spectrum has years of experience cleaning external surfaces of all kinds. This expertise allows us to select the most appropriate tools for the job and efficiently carry the work out.

As well as cleaning, we also have extensive experience in access. This means that, instead of erecting scaffolding to carry out roof cleaning and repair, we work from MEWPs. This can save our clients a considerable amount in access costs and allow jobs to proceed quickly.

Our unique roof-cleaning pole system allows us to reach areas of a roof that would be inaccessible using other means. The system also allows us to steam clean roofs using very high temperatures. This produces excellent results every time.
