What do we do? Using a low pressure washing vs. a brush
We do not pressure wash roofs with the same equipment that you would use to wash a hard surface like a driveway or a brick wall. We have 15 years experience. There are cases where brushing is not the way to go and certain types of moss require low pressure for pressure washing with lots of water volume or low PSI. We can wash a roof with a gentle touch, so gentle, that I can put my hand in front of the tip while spraying. I made some youtube vids on this if you are more visual and want to see them just let me know. Its enough to clean the roof, but not enough to do any kind of damage what so ever (baring that the roof structure is still sound). We do not know what was done to the roof before we got there. A lot of times we will not know if a roof should be cleaned until we start working on the roof. Sometimes visually we are not able to tell, during the bidding process. The low pressure washing high water is the best method to use if you are going for the brand new roof look or you are selling your house. If you want your roof looking brand new, have it washed by us or someone who knows how to safely do it. The brush will not take off the black mold and algae stains, the low pressure washing will. We inspect, we advise and we treat. The solutions vary between circumstances depending on various factors, so the first thing we do is take a look at particular areas of concern. When we have assessed the situation, we explain what we recommend to you, give you options available, and of course do the work it takes to solve the problem.
Whether we brush or low pressure wash the moss off of your roof, the most important thing is to have regular annual treatments for moss at least once a year. Once the moss is off the first time, you should never have to worry about it even growing back if done properly. Keep an eye on that roof and if you see any signs of green it must be treated. Stay on top of the problem. Regular maintenance is by far the best thing for your roof and will save you the most money in the long run.

Lots of people want me to bid cleaning but what they really need is a new roof and a cleaning would be a waste of money. I will give you the honest answer and what I think is going to be the best cost effective method. You know I am being honest because I do not install new roofs. However, we do offer a program for those who do not want to put on a new roof right away even though they need one. It goes like this – We will treat your roof for moss, clean your gutters and seal any leak hazards that I see. When I say treat it, I mean treatment only because we do not clean moss from old roofs. Also, I do not guarantee all the moss to completely die off from the first treatment. Usually it only takes one treatment but sometimes it could take two. I have never seen a roof take more then two treatments to fully kill off the moss. Also, the roof will require regular treatments to keep it dead. The treatment will not get rid of the moss, it will still be up there looking just as ugly as ever, but it will be dead so that no further damage is being done to your roof. Dead moss comes back to life faster then moss growing on a clean roof.
The meaning of hard surface cleanup – Hard surface cleaning meaning the debris that comes off of the roof from the cleaning. This does not mean that we pressure wash the hard surfaces. Basically, we are not setup for landscaping services so that is why we say that we will clean the hard surfaces, and the customer will need to make arrangements for the yard, dirt, gardens, etc. for the stuff that comes off of the roof and out of the gutters. Please note, people are always happy with our cleanup methods.

A lot of people think that the sun needs to be out and it needs to be warm in order to clean a roof. The truth is, you can get your roof cleaned and maintained just as well when its cold and rainy. We have also integrated a green policy for the treatment. Easier on the environment and your roof. First of all, we have put in an extreme effort to choose the most effective methods and products for roof moss removal in Portland, Oregon that are also friendly to the environment. There are many chemicals that have a detrimental effect, but we’ve taken the time to select the right products for Portland roof cleaning that don’t negatively affect the environment. This was achieved by years and years of tests and treatments to see which methods worked the best with a green approach in mind. Our treatment is all natural.
The best working treatment is the “Safer” Moss and Algae Killer which has a unique combination of biodegradable selective surfactants for moss removal, mold removal and is a registered organic. When diluted with water and applied, it immediately attacks that unsightly moss, mold, gunge and grime. Each time it rains, this safe, cleansing combination reactivates to help flush foreign materials without scouring the surface it has infested. We use it because it works faster and keeps moss gone longer then zinc and other products that are used commonly in roof cleaning.
Treatment for moss not to return with regular applications of treatment There are surfactants in the treatment which help it stick to the roof and keep working. I recommend bi annual treatments or as often as needed no matter what product is used. The more treatments that can be applied, the more it helps to prevent moss from returning and or getting out of control.
Moss causes long term damage by retaining water, separating shingles, and in the worst cases requiring roof replacement. Plus it just looks ugly. The good news is that it is not difficult to deal with as long as you stay on top of the problem.
Moss and molds are natures organisms that break down our structures.
If you watch the show, Life After People, it shows that in all cases moss and lykin are the first things in nature that starts to break down structures. Our structures main enemy is water, and moss retains water. If we were not around moss would break apart our streets and structures by rooting itself into it, further allowing growth of larger plants, grass and trees. I have seen moss destroy roofs, but there is a simple solution and its called, regular maintenance. A treatment at least once or twice a year in most cases will deter moss from even growing in the first place and will keep your roof looking clean. We notice that moss will come back in certain areas, even with the treatment applied but it is not nearly as bad as if it were not treated. We have tested multiple roofs on the same blocks and or side by side homes with people’s roofs we have cleaned on the same day. The customers who keep up on the regular maintenance plan with the treatment roof’s look much better. Like night and day. Multiple roof cleaning jobs are not the best thing for your roof. If done right, a few times is harmless. After the first initial roof cleaning investment, you should be able to have your roof treated once or twice a year for a lot less money.
Here is what I have seen with zinc strips. I don’t know how they can legally be sold. They don’t work, they have to be put in with nails, they break, look ugly, make noise and again, they don’t work. Regular maintenance, treatments is the right way to go for roof cleaning in the Northwest!
