The process of roof cleaning is inherently messy.

 

The moss, grime, dirt and other debris is going to have to go somewhere.

The volume of moss and other debris which can be removed from a roof is often quite surprising. Removing a tonne of moss and other debris from single house’s roof is not uncommon at all. Such a large volume cannot simply be left on the ground and mist be swept up and removed from site. Any specialist exterior cleaning company will consider this as part of the job and leave the site tidy as a matter of course.

Does soft washing debris block drains?

 

No; the moss, grime, dirt and other debris must be collected removed responsibly.

If moss and other debris removed from a roof was allowed to enter the storm drains or sewers then it would be quite possible for them to become blocked. A professional roof cleaning specialist will collect all the moss and debris an remove it from your home, possibly by enlisting the services of a third party waste removal company. Hippo bags are a good option in many cases as they are relatively inexpensive to buy.

Various technologies and methods can be used to clean a roof; each has its own benefits and pitfalls.

 

Soft washing

Soft washing is a relatively gentle, low-pressure method which uses a chemical solution to kill and detach organic matter from a building’s exterior surfaces. It is widely considered to be a highly effective method of cleaning a roof without the need for technicians to stand on the roof as long as they can get within a few feet of the surface via a scaffold tower or mobile lifting platform. The low pressure application of soft wash chemicals greatly reduces the likelihood of the roof incurring damage during the cleaning process or water ingress in to the property. The soft washing process kills all organic matter and, provided it is undertaken by competent technicians, will leave treated areas spotless, sanitised and last for a long time.

Soft Washing requires extensive training along with highly specialised equipment and chemicals to produce long-lasting, high-quality results. Access to the areas to be soft washed can be problematic in confined spaces as the solutions need to be sprayed from a few feet away rather than in close proximity to the surface.

Care must be taken to prevent soft wash solutions entering drains or falling on to landscaped areas or gardens without immediate counter treatment to prevent

 

Scraping

Scraping is a method of moss removal widely used to remove the most visible organic growth from a roof. In many cases it can be undertaken from the ground with the aid of and extending pole system. A metal blade shaped to suit the roof’s tiles attached to a pole is used to scrape moss and other debris from the surface. It is an effective method of removing heavy moss growth and – provided the gutters are cleared immediately after scraping – can reduce the likelihood of gutters becoming blocked.

The equipment required is minimal and inexpensive and can be undertaken with little experience or training. Scraping a roof can give immediate visual results but these are often short-lived because the roots of the organic growth are not removed by this process. This can promote the regrowth of moss to a greater degree than before – similar to pruning a bush in the autumn to promote strong regrowth in the spring.

The process of scraping a roof can disturb tiles and pointing; particularly as it is often undertaken by unskilled individuals from quite a distance away, making it impossible to clearly see any issues or damage.

 

Pressure washing

Pressure washing can be a highly effective method of cleaning all kinds of surfaces and many home owners will already have their own pressure washer for car washing etc., making them familiar with the principle. Water is projected under high pressure towards the surface in question in order to remove the dirt, moss, lichen and other debris. Pressure washing can yield visually compelling results with little experience or expertise from the operator.

The use of high pressure water to clean a roof carries the inherent risk of water ingress to the structure beneath. Water being forced ‘uphill’ on a roof will be forced beneath tiles and into the timber battens, felt, rafters and purlins. A greater risk associated with pressure washing is that the pressure is often so harsh that it can damage and crack roof tiles and remove vital mortar pointing.
Pressure washing can produce visually pleasing results but it is highly unlikely to remove all of the organic matter; causing faster and more prolific regrowth in a relatively short timeframe.

 

Steam Cleaning

Steam Cleaning can be used in some circumstances to clean roofs but it is more widely used by cleaning specialists to clean stonework and certain types of cladding. Specialist steam cleaning equipment, given the nature of steam at high pressure, can be extremely dangerous in untrained hands or if equipment is poorly maintained.

High pressure steam presents risks to the structure which are similar to those of pressure washing; high pressure and steam can remove mortar pointing, crack tiles and cause other damage, although it is more likely to kill all of the organic material and slow down regrowth.

 

Access

Access to a roof for the purpose of cleaning should only be undertaken by trained individuals with the correct equipment. Roofs can be slippery and in most cases it is illegal for operatives to stand upon a roof. The widely accepted best practice method of accessing a roof for the purpose of cleaning is via a mobile platform (also known as a ‘Cherry Pickers’) or with mobile scaffold towers.

Home owners should make themselves aware of their liability in such circumstances and ensure any companies or individuals they enlist to clean their roof (or any other exterior surface) is adequately insured and has the correct equipment and training to do so.

Is soft washing safe for gardens and pets?

 

It is advisable to stay indoors and keep pets indoors during the soft washing process but as soon as the cleaning process is complete, everything can return to normal. Plenty of water, fertiliser and a neutralising solution are applied to garden areas in the proximity of the clean and, in most cases, your garden will actually benefit from this treatment.

Do Roof Cleaners Climb And Stand On The Roofs?

No. In the UK, roof cleaners must never climb on pitched roofs. Doing so is proven to be particularly dangerous and exposes the roof surface to possible damage.

To avoid this, a Mobile Elevated Working Platform (MEWP) more commonly referred to as a ‘cherry picker’ or scaffold tower can be used. This allows technicians to safely work from above the roof, accessing all areas to ensure a comprehensive clean and treatment.

How long does it take to clean a Roof?

This depends on a few factors such as the cleaning method, the roof’s size and condition, access, weather conditions and the amount of moss and debris to remove.

As an indication, a typical 3- or 4-bedroom detached house with a moderate moss growth, straightforward access in favourable weather conditions should take no more than 1-2 days to complete when using the soft wash cleaning method.

Other methods such as scraping may be even quicker, provided the roof does not have any damage or incur any during the cleaning process.

Any exterior cleaning specialist should be able to provide a reliable estimate of the timeframe required after a brief visit to the site to conduct a survey.

Do you ever advise against roof cleaning?

Yes. Surprisingly often.

Particularly where a roof has been left for too long before being cleaned and the organic growth has compromised the structural integrity of the roof’s tiles and potentially damaged the structure beneath. In such instances, the only option to the homeowner is to enlist the services of a roofing contractor to repair or replace the entire roof.

An experienced specialist exterior cleaning company will only undertake a project if they are confident their work will make an improvement to the appearance and/or lifespan of the area to be cleaned and treated. If a surveyor believes the roof cannot be adequately cleaned and treated, they should advise the home owner of the best course of action to take, even if it really isn’t the news the home owner wants to hear.

Probably not

Providing we can get clear safe access to all points of the property and a water supply you can leave us to get on with it so you could go to work, do the school run or a bit of shopping and return to a clean environment.

How Much Does Roof Cleaning Cost?

Most homes in the United Kingdom will need the roof cleaning at some point in its life time. Home owners should know how much it will cost to clean their roof when employing a top professional company.

The most cost effective strategy is to prevent your roof from getting covered in moss & mould in the first place. Most modern properties would benefit from having the new roof soft washed when owners first move in. The cost for treating a new roof depends on size of course but as a general rule a modern 2 storey 3 bed semi would cost £395 plus VAT. The benefit to the home owner by choosing a well established company to carry out this treatment is that they will get a 5 year fully transferable warranty which will ensure their roof stays free from any type of organic matter growth. Having the mindset of living in a permanently clean home, no matter how long you live there is what we should all be thinking about. Re-treating after 5 years at similar low cost (inflation needs considering) will ensure this.

As roofs get older and home owners have done nothing to prevent organic matter growth such as lichens, mosses and mould, the cost to clean increases quickly. On a scale of 1-5 and 5 being the worst (usually tile failure occurs after this stage) the cost of moss removal on the same 3 bedroom semi detached house will likely be around the £2,000 plus vat cost. Why is this? Well there is a large amount of moss to remove for starters, typically a level 5 moss covered 3 bedroom semi will have a ton (1000 KG) of moss to remove, often one and a half tons is found living up there. The cost to remove moss using a licenced waste carrier is between £160 – £225 per 1000 kg bag, hippo is a leader in this type of service and bags can be bought from DIY stores for about £10, you then contact Hippo to collect when full for a charge of £160 – £225 depending on the size you need to take away.

Moss covered roofs first need the moss removing before the roof can be cleaned

Safe access must be considered by both the home owner and roof cleaning contractor. It is the home owners responsibility to ensure contractors are competent, if the worst should happen, many home owners do not realise they could be held liable. It is essential you check your home insurance policy for 3rd party liability.

Of course you should also check out the insurance policy of the roof cleaning company you intend to use, it should cover £5 million public liability as well as unlimited employee liability. Make sure it covers the property being worked upon, many public liability insurance schemes do not.

Safe Access will cost for a scaffold tower about £120 plus VAT, when a MEWP (Cherry Picker) is used the cost will be around the £500 plus vat mark.

Brushing or scraping moss from roofs is terminology often found on facebook groups for roof cleaners “looking to” get into the roof cleaning business. What methods are used depends entirely on the roof tile type, for example would you want somebody scraping with a metal blade a delicate roof tile? No you would want an experienced roof cleaning company to employ the very best method for your roof tiles.

Often the safest way to remove the moss from a roof is to use a very low pressure system, at less than 100 BAR pressure and no more than 7 ltrs of water per minute to gently knock of the roof moss from the tile. Although this can be very nessy for the surrounding area of the house, a professional roof cleaning company will clean up all the mess as soon as they have finished, ensuring there is nothing left for you to do except admire your beautiful looking home. High pressure could cause serious damage to many types of roof tiles. Start up roof cleaning companies are unaware of the risks involved and often end up causing many thousands of pounds of damage which may not be evident until a few years later.

The professional roof cleaning company spends a lot of time and money training its roof cleaners, these specialist technicians are paid on average £30k per annum. They always work in pairs as lone working is not a good idea when working at height.

Operations team members are there to ensure somebody answers your call during normal working hours to answer any questions before or after your roof has been cleaned. There is nothing worse than not being able to speak to somebody should you need to.

A typical safe roof & exterior cleaning van costs in excess of £65k to put on the road, these systems are what set us apart and why we are so confident of giving home owners the very best roof cleaning results every time.

The next step is to Soft Wash the roof with a professional grade SoftWash System which will completely sanitise the entire roof area free from any type of organic matter, moss, lichens and moulds. Essentially killing off any spores to prevent re growth. SoftWash Systems actually provide the Warranty Certificate for Purple Rhino clients. This gives you peace of mind that we have used the very best chemicals to ensure your roof stays clean for 5 years, and if for any reason we go out of business, SoftWash Systems will send in a 3rd party contractor at its expense to make sure you do not lose out. No other UK organisation offers this to date that we know of.

One man bands often do not have the capacity to learn new techniques, have no time for call backs, and often do not stay in business very long. These guys may well charge you less, but long term the investment is often worthless.

There are so many factors to think about when looking for how much does roof cleaning cost. 1. Type of Access Required. 2. Height of Roof. 3. Size of Roof. 4 Pitch of Roof. 5. Type of Tile. 6. Age of Tile. 7.Infestation Level 1-5. 8. Water Supply. 9. Land Scape and Other Delicate Materials Nearby

Fibre Cement Roof Tiles, this type of tile has a very thin membrane of colour to mimic the look of natural slate and is much cheaper to buy. When new, soft washing them will ensure they look great for 5 years, re treat and another 5 years and so on to keep them looking at their best. These type of tiles are often found on new build properties or larger homes where costs have been saved in the build process. Once moss & lichens have been allowed to grow on them, the acids secreted will have eaten through the coloured membrane, revealing a white cement underneath and when the moss or lichen is removed, the damage will be revealed, this is not caused by the roof cleaner but by the acids “eating through” the coloured membrane. This type of roof tile really needs preventative maintenance as soon as the roof is installed. A typical Surrey mansion when first built would cost between £1,000 & £2,000 to treat with a Soft Wash chemical and will come with a 5 year spot free warranty. Please remember to re book in this service every 5 years.

Yes, we can.

Purple Rhino SoftWash understands that certain cleaning needs may apply, such as touching up only the front visible roof to increase the curb appeal for a home for sale.  But it is highly recommended to avoid a partial cleaning and treatment.

Any un-treated sections most likely already have bacteria and algae spores you cannot see. These spores will travel to the treated roof sections and expedite contamination and re-growth. Therefore we do not offer the 5 year “spot free” limited warranty on partial cleanings and treatments.

Incidentally our 5 year “spot free” limited warranty is transferable if a home is sold.

We request payment made in full upon completion of work.

We accept bank payment, Visa, and Master Card.

Yes.

Can soft washing chemicals damage the paintwork on my car?

Some of the chemicals used in the soft washing process may be harmful to vehicle paintwork. Alternatively, it may be viable to create a barrier or cover with plastic sheeting to prevent debris from falling on to vehicles or other items and divert it to a convenient location for disposal.

Do Roof Cleaners Climb And Stand On The Roofs?

No. In the UK, roof cleaners must never climb on pitched roofs. Doing so is proven to be particularly dangerous and exposes the roof surface to possible damage.

To avoid this, a Mobile Elevated Working Platform (MEWP) more commonly referred to as a ‘cherry picker’ or scaffold tower can be used. This allows technicians to safely work from above the roof, accessing all areas to ensure a comprehensive clean and treatment.

Soft washing is far gentler on masony, roofing materials and exterior finishes

A professional soft wash cleaning system is designed to apply cleaning solutions at 45 -50 psi, from about 6 feet away. That’s similar garden hose or a hard rainfall.

Soft washing equipment is so-called because it washes softly. Yet very effectively.

We use Softwash Systems’ Cleaning and Treatment Process

All Purple Rhino SoftWash technicians are trained to use the premier SoftWash Systems cleaning and treatment process, involving the use of professional grade, low-pressure applications of the proprietary SoftWash Systems Cleaning Solution.

Each exterior surface to be treated is analysed to determine the best course of treatment.

We will not use a pressure washer around your property.

Yes!

Untreated roofs may lose up to 50% of the expected roof shingle life cycle. The black streaks (bacteria) are eating the limestone in the shingle and causing erosion. Roof bacteria, moss, lichen and algae all cause granular loss from shingles. The bacteria weaken the shingle, the fibre root systems moss and lichen cause discoloration, and can cause small cracks in shingles. The resulting damage will lesson the life cycle of the roof. Granular loss also reduces reflection of the suns UV rays and protection from the elements.

The earlier your roof is cleaned and treated the better!

Soft washing completely removes bacteria, algae, moss and lichen from your roof which can extend its lifespan.

While other methods of roof cleaning may be cheaper, they are unable to remove 100% of this organic matter; giving long-lasting results. This is why Purple Rhino chose soft washing as our primary cleaning method.

Spot free warranties for roofs lasts for 5 years and can be transferred to a new owner if you sell your home.
