How to Securely and Efficiently Clean a Roof

There is a lot of debate online about the best approach to clean roof tiles that is both effective and will not harm your roof. MBE Pressure Washing Company are experienced exterior cleaning service in Massachusetts, that focus on roof moss treatment and soft washing roofs.

This post is based on our experience cleaning moss, algae, and grime off tiled roofs, as well as information from other experts. An adequately treated roof enhances the appearance of a house or business structure by returning it to its original color. Clients, residents, and even visitors frequently comment on how new the roof seems.

Roofs may develop a thick carpet of moss, algae, lichen patches, and dirt if left untreated, making them appear ancient and unkempt. What seems to be dirt is frequently black algal stains that have infested the roof or just one side of it. Moss and algae grow in dark and damp environments, therefore locations with little sunshine or those shadowed by overhanging trees or other structures tend to be the worst impacted.

But then again, after the moss has been removed, the tiles may be readily cleaned at low pressure using the proper highly specialized soft washing cleaning chemicals, and a pesticide or biocide will keep moss and algae from returning for at least a year, and very definitely much longer. In our experience, the substance we use works effectively for several years.

Is moss destructive to roofs?

If you do any study on moss and its effect on roof tiles, you may come across contradicting information and viewpoints. Obviously, roof cleaning firms would state that moss can injure and destroy roofs, while another website will deny this allegation. As a matter of fact, the most respected and independent roofing specialists believe that moss should be eliminated to preserve and extend a roof's lifespan.

Roof moss can cause the following problems:

• Clog gutters and downspouts
• When moisture is retained by the tiles, it can deteriorate the roof structure
• As it develops and expands, it breaks tiles and causes fractures.
• Tile protective coating deterioration
• Roof leaks are caused by damaged tiles.
• Develops into mortar joints trying to hold ridge tiles, causing the joint to crack and the tiles to become loose.
• contribute substantial weight to a roof
• When it blows off, it leaves a mess on your driveway and patio.

Is pressure washing roofs safe?

Using a strong jet wash or high pressure washing is not advised since it might harm the layer of the slate or tile, while also affecting its estimated life.

Other compelling reasons to avoid high-pressure roof blasting include:

• The horrible mess that power washing at height would leave all over the customers and surrounding homes. Moss and dirt would fly much further in high winds.
• The possibility of harming and dislodging tiles
• increased expenses incurred as a result of hiring pricey agents
• the possibility of water running inside the home
• Pressure washing eliminates surface debris and has no effect on killing or removing algae and lichen spores beneath the surface. This implies that they will rapidly invade and conquer the roof, making it seem unclean and stained with black. 
• Resulting from walking on the roof

Is it secure to gently wash a roof?

Yes, in a word. Of course, it should be done by an experienced soft washing firm that utilizes safe, authorized soft washing cleaning materials, but when done properly, soft washing is absolutely safe.

What exactly is roof soft washing?

It is the use of low pressure to clean and remove black, dark green, and red algae, lichen, moss, various biological spores, and debris from outdoor surfaces. It was created to clean delicate materials that could be harmed by pressure washing.

Soft washing is ideal for cleaning:

• exteriors of houses and buildings
• shingles on the roof
• cladding, fascia, and soffit
• brickwork
• render

Each of these surfaces is vulnerable to being damaged by intense water jets. Soft wash chemical compounds are sprayed at a soft low pressure by window washers using extended water supplied poles. The product is sprayed over the surface and gently stirred with a brush head or nozzle. Long reach poles are ideal for reaching difficult-to-reach regions such as the tops of roofs, gutters, and walls.

The cleaning solutions we apply are particularly designed to remove the dark black algae that cover roof tiles. They are easily washed off with clean water when they have had time to take action, and the procedure is repeated if necessary to get a brilliant and fully clean, making the roofs and external walls of your home seem like new again.

Another advantage of soft wash cleaners is that they keep your roof cleaned for a significant period of time. This is due to the fact that algae spores are naturally soaked up into porous materials such as roof tiles, and pressure washing by itself cannot clear them.

Soft wash biocides, on the other hand, are partially absorbed into the tile, killing all the invisible spores beneath the surface and preventing them from repopulating the tiles. A jet-washed surface will only clean the exterior region, which means that algae spores will begin to spread again after washing, and the surface will quickly seem unclean again. Following mild soft washing, we spray a very efficient long-lasting anti-fungicide to keep your roof clean and moss-free for a long period.

Then what's the ideal technique for cleaning a roof? Is it Power Washing or Soft Washing?

Given the facts shown above, MBE Pressure Washing Company considers that applying low pressure soft washing techniques is the best, safest, and most efficient method to clean roofs.

• It is cleaner, more spotless, and less inconvenient for you and your neighbors.
• More inexpensive
• It will not do any serious harm to the roof tiles.
