    Commercial Roof Cleaners

    As a business, it is essential for you to maintain the physical appearance of your property and buildings. One way to enhance your curb appeal is by keeping your business’s roof free of debris and moss.

    If your roof is unkempt, this can inspire distrust in potential clients or customers, who may wonder if a dirty roof is a sign of more serious business problems.

    To mitigate the risk of losing valuable clients, enlist our professional roof cleaning service to visit your commercial building and bring your roof under control.

    To learn more about our commercial roof cleaning services or to book a roof cleaning technician to visit your business, give Evergreen Window Cleaning and Home Maintenance a call today.

    Residential Roof Washers

    Our well-trained technicians have experience cleaning nearly every kind of roof, enabling them to quickly fine-tune our cleaning process to the unique needs of your home’s roof material.

    As a general rule, we recommend that homeowners have their roofs professionally cleaned twice a year, once in the spring and again in the autumn. This ensures that seasonal debris and moss aren’t given time to inflict damage to your roof.

    What types of roofs do you clean?

    We clean most roof types: composition, aluminum, cedar shake, torch-down, pvc, and many types of tile. There are a few exceptions, however. We don’t clean soft aluminum tiles for example, due to damage liability. We also don’t clean roofs we aren’t equipped to clean safely or roofs in need of replacement or serious repair. If you have any questions about our roof care and soft wash options for your own roof, please contact us.

    Why does your company use high pressure washers to clean roofs?

    The short answer is, we don’t. We use all our washers on low-pressure with wide tips so we don’t harm your roof.

    The long answer is, yes, it is a well-known fact that pressure washers can do a lot of damage. A high-volume, high-psi pressure washer can actually bore a hole right through concrete without much problem! Knowing this has rightfully made most homeowners wary about having anyone pressure-wash their roofs. And a lot of contractors, who know less about pressure washers than they do about the potential damage they can do, insist that a pressure washer should never be used on a roof.

    To that we say, “abusus usum non tollit,” the abuse of something doesn’t negate its proper use. Just because knives pose a threat to small children, doesn’t mean we don’t keep a few in the house and use them for preparing meals. We all know about knives because we all use them. Not everyone, however, knows about pressure washers. The truth is that a commercial pressure washer in the hands of a well-trained tech is often the softest and best approach to moss removal, especially where the only other alternative is to use a wire brush. Because there is so much misinformation about pressure washing roofs and too many “cowboys” out there with pressure washers, it might be useful here to share one piece of knowledge our techs have about washing roofs that most people and many contractors* don’t.

    Still feeling wary? Here’s a detailed explanation of how it works. You might know that the type of tip used at the end of a pressure washing wand is one of the essential components in determining the outcome of a project. And you might also know that pressure washers come with a set of tips of varying degrees, from 0° to 40° plus a rinse tip. But did you know that those tips are sized to match your specific machine? If you own a 4-gpm 4000psi machine, you will have a set of four tips labeled 0004, 1504, 2504, 4004. The first two digits in each of those numbers tell you the degree of the flow of water from those tips: 0°, 15°, 25°, and 40°, respectively. The last two digits tell you the size of the orifice. In this case, 04, for the 4 gallons per minute (gpm) of water your machine is designed to draw. Now, if you were to replace these tips with size 08 tips on this particular machine, your pressure would drop substantially while you would maintain the same flow rate. You would now have a 4gpm 1000psi machine.

    In our case, we ordinarily use 8 or 10gpm machines at 3000 psi for concrete, aggregate, and other hard surfaces. The tips we most often use are size 09 or 10 tips. However, when cleaning roofs, we use size 12, 15, or more, depending on the roof type and condition to drop the psi dramatically and eliminate the potential for damage.

    This may be more than you care to know, but furthermore, there are many other things a well-trained technician knows about pressure washing such as where to hold the wand in relation to the surface, pre-soaking with cleaning agents, what types of other tools can be used, when not to pressure wash, to name a few. All our techs are well-trained, smart, and experienced in cleaning roofs. If we offer the Roof Wash as an option for your roof cleaning, it will be done carefully with minimal abrasion and the end result will be beautiful.

    *Many roofing contractors know that psi can be adjusted downward. They also know that a pressure washer in the hands of a well-trained tech is often preferable for roof cleaning to rubbing it over with a scraper or a wire brush. But, since they have no idea who’s doing the roof cleaning, or what kind of training they might have, they often simply recommend against pressure washing roofs for anyone except themselves.

    How often should I have roof washed?

    The best option for the life of your roof, whatever type, is to never wash it (or brush it, for that matter), but to maintain it regularly by blowing off the debris and treating the moss. However, this might not cut it for aesthetic preferences, especially if maintenance has been long-neglected.

    Aluminum, rubber tile (faux slate), and thick concrete tile may be washed every few years as needed without causing leaking or reducing the life of the roof. And those who simply must have their composition roof looking completely new in a very short period of time (e.g., the house is going on the market), soft wash may be the best option. If you have questions about your own situation, please don’t hesitate to ask one of our techs.


    Do you clean with air-compression?

    We use air-blowers (leaf-blowers) to remove loose debris from roofs, and we use high-volume, low-pressure pressure washers for more thorough roof cleaning, but we don’t use compressed air. We want to provide excellent cleaning service to our customers and haven’t been convinced that air-compression cleaning does a great job. Unlike water, compressed-air leaves a lot of dirt behind, yet it is still hard on the roof.

    If a roof must be cleaned and made to look like new, correctly pressurized water in the hands of an experienced tech is the way to go. If routine leaf/debris removal is required for roof cleaning, a top-of-the-line commercial backpack blower is all that’s needed to get the job done.
