Soft Washing And Pressure Washing – Which Is Better?

You can do both pressure washing and soft washing and to keep your surface neat. But you might be considering which choice is right for your surface. In the further explanation you will get to know everything about soft washing and pressure washing with their differences and functions.

The Fundamentals

Soft washing and pressure washing, both are methods of cleaning your roof surface and around your house. They are both considered a type of power cleaning. Pressure washing is known to be rougher in washing the surface than soft washing. Pressure washing can reposition deep-rooted contaminants with the surface, making it a perfect method for cleaning hard and porous surfaces like concrete. Soft washing has a lighter pressure which can minimise the cleaning power while making it simple for softer surfaces to handle. Luckily, most pressure washers have adjustable pressure settings. You can pick a high pressure or a low pressure wash with different machines, likewise, all pressure washing companies have adjustable pressure washers and they can choose the right one for you based on the type of surface you have.

Soft Washing vs Pressure Washing

While it is possible to pressure wash and soft wash your roof, roof cleaning is best left in the hands of professionals. This is because roofs are made from more delicate materials such as wood, ceramic, slate, tiles, concrete, clay and asphalt. These materials require a more precise and gentler cleaning approach.

When pressure washing is done by an amateur, it can cause more damage than good. Hence, the need for professionals.

Professionals will employ the use of a specific type of cleaning method called soft washing or pressure washing to effectively clean your roof.

Soft washing a roof is different from pressure washing.

Pressure washing is not ideal for roofs that are old or made of a soft material like asphalt, ceramic and clay because high pressure water can damage the delicate roof materials. Soft washing is a much better alternative for these kinds of materials because it relies on the use of a biodegradable cleaning solution to remove moss, dirt, algae, debris, dust, mildew, mould and other unwanted substances from the roof.

In addition, soft washing is much better at addressing the issue of mould, algae or mildew on your roof. The cleaning solution used by soft washing does not only kill the unwanted materials, but also prevent them from germinating again. Hence, your roof will remain clean and attractive for a longer period of time.

A professional pressure washing can achieve some really fantastic results. Where regular cleaning and maintenance fails to work, only pressure washing can take care of the build up of grime.

Pressure washing involves the use of high pressure water to clean the surface. Soft washing is similar to pressure washing. In the case of soft washing, the pressure per square inch, or PSI is lowered to less than 500, making it safer to use on less durable surfaces.

Pressure washing removes growths and contamination on the roof surface with great force. Unfortunately, this often causes damage, which has been seen countless times. This is the case with manufacturers of the most common roof and exterior building products continuously warning against using pressure washing to clean their products. It can make warranties of such products void.

Chemical cleaning or as simply called soft washing is a much gentler method that uses no more pressure than a garden hose. The result of soft washing, particularly on roofs and building exterior is by far superior. The results are obvious in a few minutes.

Does Soft Washing A Roof Work?

Soft wash roof cleaning has become a rampant way to clean roofs without damaging them. With this method, you can get rid of all the dirt and grime on the surface of your roof while also getting up close and personal with any moss or mould problems. This is a major reason why soft wash roof cleaners are becoming more popular these days. Even though it takes longer than a traditional pressure washing process, it is worth waiting for it because it leaves your roof cleaner for a much longer time afterwards. Pressure washers will often leave behind residue that can end up corroding your metal chimney or even cause leaks in the future. If you are looking for a great way to keep your home in excellent condition, then soft wash roof cleaning is an excellent option to consider.

Soft washing roof cleaning is an environmentally friendly process that entails adding a special soap solution to the surface of the roof. The best method for soft wash roof cleaning is to use the safest detergents available, which are non-hazardous and environmentally friendly. They are biodegradable, free of fragrances or perfumes, with no petroleum distillers or harmful solvents, making them safe for you and your family. As much as soft washing is safe on your rooftop shingles, these chemicals washes away years of debris accumulation without harming any plant life around your garden. A soft wash washing system uses less water than pressure washing equipment, as such, it protects the environment by minimising the volume of water that flows into your surroundings. You can also use your lawn’s sprinkler system to water your grass after the cleaning process is completed instead of using a hose to get rid of any leftover soap.

Soft washers typically only see results in 1 to 2 cleanings per year because it takes much longer than the pressure washing method. Also note that pressure washing leaves an unsightly residue behind where the chemicals have been used, which can damage metal chimneys and cause problems in the future. With soft washers, you can get a thorough clean anytime you need it.

How To Soft Wash A Roof

Below are what you can expect when a professional uses a soft washing method on your roof.

Inspect The Roof

Before soft washing, professionals will conduct a thorough inspection on your roof. It is important to address roof issues beforehand in order to ascertain the level of damage and to maximise the effect of the roof soft washing.

Pre Washing The Roof

Professionals will use low pressure water to saturate the roof. Pre-washing the roof can improve the adherence or the effectiveness of the soft washing cleaning solution.

Applying The Cleaning Solution

The professional will use a soap dispenser nozzle to apply the cleaning solution to your roof. They will work in small sections at a time for a more systematic approach. The cleaning solution will be allowed to sit on the surface for at least 15 minutes before rinsing off.

Soft Wash The Roof

Professionals will then use a soft washer to rinse the solution from the roof. A soft washer uses low pressure water so there is no risk of damage to the surface of your roof.

Application Of Sealants

If there is need, the professionals will apply a sealant to restore the protective layer of your roof. They will only apply the sealant once the roof has completely dried up. In some cases, it may take more than 24 hours for the surface to dry.

Does Pressure Wash Damage Roof Tiles?

The roof is an important part of any structure, but it is also one of the most vulnerable parts of the building. It is always exposed to sun, wind, snow and rainfall. Constant exposure to these natural elements will definitely affect the appearance and quality of a roof. For example, the sun’s UV (Ultra Violet) rays can break down the roof shingle aggregates which is the protective layer that helps extend the lifespan of a roof. Even if your roof has the best quality materials and construction, it will be susceptible to wear and tear over time.

However, roofs can have overgrowth of mould, moss, algae, mildew and other organic material.

Not only do they leave unattractive stains on your roof, but they can cause shingles and other roofing materials to get bad.

In the face of all these issues with roofs, a proper roof cleaning maintenance can be used to solve them.

A professional roof pressure washing should be carried out at least two times a year. One can be done during the spring while the next can be done during the fall. Pressure washing not only restores the appearance of your roof, but it can also effectively flush away the harmful substances that damage the roof materials. Pressure washing is also a critical step that needs to be taken before re-applying protective sealants on the roof.

Professionals can get a good look at your roof and identify issues before pressure washing.

One of the problems of pressure washing is that, pressure washing loosens the UV protective granules and practically guarantees that your roof will fail either immediately or in the course of time if mishandled.

How Pressure Washing Operates

With pressure washing, you can channel a fully-compressed water at a surface in order to blast away contaminants. Pressure washers have different power ratings given in pounds per square inch (PSI). In general, pressure washing is considered the best method for getting rid of loose paints or stains from surfaces, let’s say you’re trying to remove old paints or stains for another layer. The huge setback of pressure washing is that it can damage surfaces when used badly. Applying high-powered pressure to a deck for instance, can cause a serious damage to your surface. Wood is much softer than concrete, so you need to make use of a different PSI.

The Benefits Of Pressure Washing Over Soft Washing

Pressure washing is an extremely effective solution for cleaning various surfaces of the home. Unlike power washing that uses heated water with high pressure, pressure washing does not use hot water. However, the pressure is still high enough to be dangerous. Amateurs often learn the hard way about the cutting power of a pressure washer. Water is being pushed out at such a high rate, it can cut through a finger to the bone in a space of a few seconds. It can also do something like carving a pumpkin or descale a fish at 60000 PSI.

All that has been said, special care must be taken when pressure washing your roof. You need to be at the right distance to avoid wearing down wood or asphalt shingles, and other types of susceptible house siding. Pressure washing is meant to clean hard surfaces or stone pathways. Anything hard, but has deep grooves that allows dirt to be embedded is a huge candidate for pressure washing.

Pros And Cons Of Pressure Washing

One of the biggest advantages of pressure washing is its effectiveness. However, when that type of power is in the hands of an inexperienced person, it can quickly become a dangerous situation. This means that the force used in pressure washing is both a disadvantage and also an advantage. Its use depends majorly on the training and experience of the person doing the pressure washing. To sum up, with pressure washing, there is a risk of damaging property. If the pressure is too intense and is applied too close to the surface that is being cleaned, it can cause damage. Too much washing can tear up a wooden roof material if done incorrectly.

There are several reasons as to why some people might think of using a high pressure washer on their roof.

  • It could be to brighten up or clean the roof
  • It could be to get rid of moss that has accumulated on the tiles
  • It could also be a way of preparing for a roof coating or sealant.

But below are reasons why you should not pressure wash your roof tiles. Most of the roof tiles in the UK are made from concrete and have a sandy finish on the uncovered side of the tile. This part of the tiles is built to gradually wear off until the tile needs another replacement, and replacing it is usually after 80- 100 years of weathering.

The reasons are:

  • Some roof experts warn that roof tiles should not be subject to high pressure washing for any reason. Getting rid of lichen, and moss by pressure washing will constantly remove the surface finish and potentially bring damage to the structural integrity of the tile, this procedure is followed by a surface treatment application which would constantly nullify any tile manufacturer’s guarantee.
  • Interlocking roof tiles are not meant to be stepped upon, foot traffic can cause these interlocks to break, opening the roof up to take in water.
    It is unsuitable to pressure wash roof tiles as this can potentially force up water between the tile and the roofing to be felt inside the roof space.
  • Bedded mortar and flashings can as well be blasted off using this method, potentially leading to further cost for making corrections.
  • It pertains to the risk of flooding to the loft of the roof. A typical roof is designed to stand the test of the element, it is not meant to cope with water being forced out from a nozzle at such a high rate. The water may perforate past the overlaps in the tile and enter the roof.

The Benefits Of Soft Washing Over Pressure Washing

You may now be thinking that soft washing has nothing to do with pressure washing, ironically, pressure washers are used to soft wash, but they are modified to lower PSI. Soft washing is done using less than 500 PSI for rinsing or cleaning applications. The pressure washer tips are replaced with that one that widens the spray of water, therefore dropping the point of pressure. On top of this, soft washing makes use of a special cleaning solution to break down dirt and organisms living on the surface. These cleaning solutions are environmentally friendly and will not strip protective coatings on your home’s roof surface. Soft washing methods are preferred in a variety of conditions over pressure washing and that includes delicate surfaces.

Pros And Cons Of Soft Washing

The advantages of soft washing just like effectively cleaning your roof without causing any kind of damage or hurting your environment are apparent. The drawbacks, however, is that less pressure means that for some surfaces, it is more challenging to get them clean. Because of this, the lower pressure has on force. Hence, in itself it does not cause damage. On the other hand, its disadvantage is that it takes longer time and it is a repeated application to get a surface free from accumulated grimes.

How Soft Washing Operates

Soft washing is a low pressure wash, you still use higher pressure than you would with something like a hose, but soft washing allows you to reposition contaminants without harming your surface.

Soft washing allows you to get rid of algae, mildew, dirt and other contaminants from your surface, you may want to use soft washing on softer woods for instance, or to prevent impacting the structural integrity of a concrete that is newer than 3 years.

While it is a good benefit to cleaning your roof, this is not the major thing. Soft wash roof cleaning is recommended by many companies that manufacture roofing materials. It is a known fact that in all major roofing warranty coverage, soft washing is the only method to clean your roof which extends the life of your roof by up to 15 years. That can be achieved if you get it done on a regular basis (let us say every 2-3 years). Instead of you spending a fortune replacing your roof, a little investment of soft wash roof cleaning can extend your huge investment and still keep your roof sparkling clean all year round.

Benefit Of Soft Wash Roof Cleaning

Saves you a whole lot of money on roof repairs and replacing your roof earlier enough than you expected

Energy Efficiency

Things like algae, black streaks and moss reduce the energy efficiency of a roof rating, thereby making you waste money on heating and cooling.

Manufacturer’s Roof Warranty
