House Washing Northern Virginia

Take care of your most valuable investment! – House Washing Northern VA

We at Patriot Pro Clean uses LOW pressure, detergent based methods for the safest, most thorough house wash Northern VA! A type of clean you won’t get by blasting high pressure at, for example, vinyl siding. Not to mention by doing that you are forcing water underneath the siding and likely causing mold and mildew to grow where you can’t see it.

Another huge benefit to our cleaning is that it stays clean longer. Our detergents actually kill the mold spores on the surface so they take longer to return. Just using water will not completely remove these spores.


So, how much pressure? House Washing Northern VA

Less than you think! We use around 300psi give or take. Most of your homeowner grade units are around 2 gallons per minute, 2500-3500 PSI and greater. We use exactly the opposite, high gallons per minute, low pressure. Giving your home the safest,  most thorough washing!

The benefits to “soft washing

  • Gentle on the surface being cleaned
  • Does not mar the surface
  • Does not strip paint
  • Doesn’t force water behind seals
  • Actually kills organic growth
  • Does not make oxidized surfaces look worse
  • and more!

We use the same technique for vinyl, aluminum siding, dryvit, stucco and some brick.

Roof Treatment

The Low Pressure Process

We use strict low pressure applying detergents, it is important because the shingle is a delicate surface. Great harm can be done by using a pressure washers or other type of high powered cleaning devices on the roof. The detergents we use are safe and biodegradable, yet very effective at cleaning. Our process specifically is recommended and approved by big name shingle manufacturers.


How it Works:

Using a low pressure application pumps, we apply a mix of our soaps at varying percentages depending on the level of soiling on the roof. As soon as it is applied our cleaning solution attacks and penetrates at the root to kill the fungus. Sometimes results are immediate, other times it can take up to a few weeks for full results.

What is The Streaking From?

roof cleaning centreville va
Gleocapsa-Magma is the black algae that streaks and discolors roofs. Moss and Lichen colonies can also develop on the shingle surface.

There are a lot of common misconceptions of what that black streaking really is. It is actually just algae! There are three main types of organic growth that roofs tend to grow (Gleocapsa Magma, Moss and Lichen). Most shingles contain some key ingredients that allow the growth to feed on the shingle. While in most cases this is just a cosmetic problem, if allowed to get heavy enough the algae can cause serious deterioration to the surface.

Deck Pressure Wash and Staining

Another Deck Professionally Restored by Patriot Pro Clean

Wood deck and fences can be a big investment. That investment does unfortunately require periodic maintenance to withstand the elements over years to come. We can take an old, weathered deck and clean it to remove surface contaminates like mold, dirt, algae etc. Our multi-step process correctly preps the surface for proper staining.  The stain that is used is very important. In the past 10-15 years many “stains” have been introduced out in the market that cause more harm than good in the long term. They crack and peel after 1 or two years and then when it comes time to remove them to reapply, it can be very difficult. Patriot Pro Clean only uses penetrating oil deck stains.

Our professional restoration service is not just a simple “blast the wood with 4000psi”. We use a combination of fairly low pressure, the right neutralizing detergents and proper wood cleaning technique. On a normal sized deck it can take several hours to clean depending on numerous factors. Once it is done, the wood needs to dry for a minimum of two days prior to staining. When the moisture level is an acceptable level, the finishing touch can be applied. The preparation is a major part of the end result.

The oil deck stains that we use are the best for the health of the wood. They replenish the natural moisture in the wood, plus they don’t crack or peel. When it comes time to re-stain, the process is straightforward as maintenance with an oil stain is simple. It is easier to strip and most of the time re applying stain doesn’t use up as much material. Patriot Pro Clean gives a discount to repeat customers for deck maintenance.

Roof Stain Cleaning | Northern Virginia

Before and after of a low pressure roof clean

Roof Cleaning done the right way!

Black algae streaks taking over your roof in NOVA? Patriot Pro Clean uses a safe, very low pressure cleaning method for asphalt shingle roofs. In fact, it is the only method approved by the Asphalt Roofing Manufacturers Association (ARMA).

Our techniques allow us to clean the roof effectively, while using fungicides to kill the algae/organic growth. Instead of what some other companies do by pressure washing the shingle, just blasting the mold away and not actually killing the growth. Additionally, when an asphalt shingle roof is cleaned the wrong way, it is stripping granules off the surface. Causing premature replacement.

If your roof is structurally sound and is just dirty, instead of spending thousands of having it replaced, just spend a few hundred to have it cleaned. Besides, most roofs look new when cleaned!

Things to know about Gleocapsa-Magma

There’s a lot of talk about the common roof stains or roof streaks that appear all over Northern Virginia and across the southeast.

That would be Gleocapsa-Magma, it is an airborn algae stemming from cyanobacteria. It is the cause of the staining you see on many roofs along the region. Mix with humidity, lack of sun (more shade) and a food source, you will have a perfect petri dish for the organic growth of Gleocapsa-Magma (AKA a asphalt shingle roof)

Where to expect the airborn algae to grow?

  • In climates that get warm and humid
  • On north facing sides of roof
  • On parts that are blocked by shade
  • Also where there is excess moisture or where some downspouts dump onto the shingles.

What’s the “food source?”

Since all living organisms need some sort of food, the algae does too. Asphalt shingles are constructed of parts of limestone,  this is what the growth feeds on, eventually eating through the shingle.

Moss and lichen have similar characteristics.

Safe, No Pressure Roof Cleaning

We provide low pressure roof cleaning to our fellow Nokesville residents, Prince William county and surrounding areas!

Using a soft chemical application with fungicides mixed with some cleaners, we can safely remove and kill the organic mold growth that is on your asphalt shingle. Virtually any other method is unsafe to the integrity of the shingle and reduces life span. What is also damaging to the shingle is letting the growth take over and eat away at the limestone in the shingle, causing premature wear.

You may know of them as roof stains, roof streaks, black streaks but they are really an airborn algae called Gleocapsa-Magma. Our method of cleaning is the ONLY method approved by the Asphalt Roofing Manufacturers Association (ARMA).

Roof Streak Removal And Roof Stains – Low Pressure Cleaning

Got those nasty black streaks slowly taking over your roof?

You do NOT need a new roof because of it! If your asphalt shingle roof is still structurally sound, it can be cleaned safely and properly. It’s the EASIEST way to make your roof look new, without actually buying a new roof!

SO, what is it?

The black roof streaks that are attacking many homes in the Northern Virginia is “Gleocapsa-Magma” . It’s a airborne algae that feeds on the limestone in the asphalt shingle. Many shingles have a protective coating to prevent algae when manufactured, but that coating wears off in 3-7 years.

What does it do?

Gleocapsa-Magma, like other types of organic growth you may have on your roof, feeds on whatever it’s on. Overtime, if not addressed, the algae can eat through the shingle causing premature wear. That’s when the shingles will need to be replaced.

How is it cleaned?

Asphalt shingles are fragile, due to their composition of fine granules, so they require a gentle cleaning. Pressure washing is not gentle on shingles. What we do at Patriot Pro Clean is a very low pressure chemical based cleaning.

Two major advantages of low-pressure roof cleaning

  • Low pressure is used to avoid the premature wear of blowing off granules 
  • Since the cleaning is chemical based, all organic growth on the surface is eliminated. With pressure washing, traces of the organic growth is still alive and well on the shingle.

(Not to mention, our cleaning method is the ONLY method approved by the Asphalt Roofing Manufacturer’s Association – ARMA.)

A quick “tip” for DIY pressure washing

If you are into DIY pressure washing, read this first!

Might spare you permanent damage to your property!

Here is some good info on do it yourself pressure washing, click here!

When using the “red tip” 0 degree nozzle on your homeowners grade pressure washer, it can inflict some damage, to virtually any material or surface.  From using the concentrated 0 degree spread of the tip you can go from saving a few bucks to potentially causing thousands   in damages.

It is always best practice to use the “white tip” or 45 degree. Some store bought models will vary. When using the wand, stand back at a safe distance and slowly get closer to the substrate you are cleaning.

Remember, high pressure is not always the answer, here at Patriot Pro Clean we use the lowest pressure possible to lower the risk of damage.

Happy PW’ing!
