Can You Pressure Wash a Roof? Answered!

Your roof takes a beating. It protects you from everything mother nature throws at it. Debris carried from severe weather, birds using it as a bathroom, and flowing water negatively affects your roof. Take a look at your roof. Does it look like an ugly painting? If so, you are in dire need of a roof cleaning.

It is one of the most important aspects of a home, so why not give it some special treatment? Neglecting to pressure wash your roof will only cause issues in the future.

 

How Did This Happen?

Algae thrive in humid areas; roofs that are shaded from the sun develop more moisture which creates an area perfect for mold and mildew to grow.

The main cause of a filthy roof is neglect. Too many people overlook this small but significant problem. You must pay attention to its condition before moss begins to overtake your beautiful roof.

 

Can You Power Wash a Roof By Yourself?

The question isn’t really whether you can DIY roof power washing. Sure, you can but should you? Should you pressure wash your roof without professional help? The answer is no.

Roof washing is a tricky task, especially when pressure washing machines are involved. Amateur pressure washers often make errors, such as use the wrong nozzles, cleaning solution, or pressure level. Here are just some of the problems that can arise if you opt to pressure wash your roof yourself:

  • Speed up the deterioration process by at least three times
  • Accidentally remove protective granules on shingles
  • Compromise the adhesive connecting the shingles
  • Damage the shingles or the fabric of the roofing material
  • Crack the tiles, cedar shake, and slate roofing
  • Unintentionally spread moss and algae
  • Weaken the roof structure and cause leaks and water damage inside your house

 

Soft Washing and Other Alternatives

The first option is called soft washing, otherwise known as chemical cleaning. To do this, start by thoroughly soaking the plants in your house with water.

Using a tarp, cover more sensitive plants and flowers to protect them. Next, use soft pressure to wet your roof before spraying it with a chlorine-based gel. Leave it as is for a short while, then use a pressure washer on low pressure to wash it down from top to bottom.

Other alternatives don’t require water. You can use a soft brush or broom to sweep dust and dirt off your roof. While this is a less thorough solution, it can still be quite effective. Another option is to use a garden blower to get rid of debris. Finally, to combat mold and fungus growth, apply a roof treatment all over.

 

Can You Pressure Wash a Roof Without Professional Help?

The water pressure level combined with the cleaning solution that must be used should be decisions made by a professional. If you insist on pressure washing roof shingles, hire a service company to do it every 2-3 years.

One of the reasons homeowners choose not to hire a pressure washing service company is because of the perceived high price. Contrary to popular belief, however, roof cleaning contractors aren’t very expensive. Contractors usually charge somewhere between $200 to $800, depending on the service.

While $800 seems like a lot to shell out, that’s nothing compared to the cost of replacing your roof entirely, which is a real possibility if you don’t keep your roof clean or decide to do it yourself. In the end, these roof cleaning costs are worth it.

 

The Benefits of Roof Cleaning

Roof cleaning can be a tedious and costly job, but it’s necessary nonetheless. Here are the benefits of keeping your roof clean:

 

1. Avoid Future Expenses

This is especially true when dealing with maintaining properties. Companies implement preventative maintenance to avoid equipment failure or facility damage which, in time, saves them from ordering replacements.

The same thing can be said about your home, specifically your roof. As time passes, mold and algae form on the roof’s material and can eventually damage individual shingles. The roof’s structure is then exposed which can lead to decreased insulation and even water leaks.

Soon, you will have to repair your home’s interior all because of some stains on your roof. A scheduled roof cleaning allows you to defend your home from damaged surfaces and avoid expensive replacements.

 

2. Improve Your Home’s Curb Appeal

Next time you drive through your community take a look at some of the houses. Are their roofs stained as well? A home with a dirty exterior is unappealing. If you are trying to sell your home, unsightly marks and mildew may deter potential buyers. Not only is it an eyesore, but it also reflects that the structural integrity may be compromised.

A simple roof cleaning can dramatically change the image of your home. Your home’s curb appeal will improve and possibly increase property value. To maximize this opportunity, tell your neighbors about the benefits of cleaning your roof. Soon, your community will be filled with homes that look brand new.

 

3. A Healthy and Leak-Free Household

It’s so high up that homeowners usually don’t bother looking. But, a damaged roof can lead to more serious problems.

If you don’t keep your roof clean, the damage caused by mold and other fungi can pile up and, eventually, compromise its structural integrity. This can give rise to water leaking into your house, taking all the mold and mildew with it. And, as you may know, mold, algae, mildew, and other filth can be detrimental to your health. By cleaning your roof, you’re assured of a healthy and leak-free house.
