At Roof Life of Oregon, we recognize that hand picking or scrubbing your roof would not be the most economical roof cleaning solution for you or our company. Instead we use a low pressure/high volume water system to help schluff off the moss and algae living on your roof. At first glance, the system we use looks like a pressure washer. If you were driving by while one of our treating crews were working you might think they were pressure washing the roof. The difference lies in the equipment we use and the technique our technicians use. Our cleaning trucks are comprised of custom specialty equipment and all of our technicians are trained to use the lowest amount of pressure possible during the cleaning process.

There is not doubt that pressure washing your roof will be a cheaper solution today than choosing Roof Life of Oregon’s roof cleaning process. However, if you don’t want to replace your roof 10-15 years sooner than the stated manufacture warranty (see the photo above) then choosing Roof Life of Oregon is your best long term solution for peace of mind. Roof Life of Oregon offers a free roof inspection to help you determine the current condition of your roof. Call us at (503) 925-0125 or visit our roof inspection form sheet to have one of our roof consultants give you a fair and honest roof evaluation.

A thin sharp metal strip flapping in the wind which is extremely dangerous! After rain has run over your zinc strip for a year or so, they loose all of the effectiveness of preventing fungus and moss growth. In addition, you have a ton of extra nail holes through your roof which can cause even bigger problems: leaks and wall damage.

Home Depot sells zinc strips for only $20.92 per 50 feet. While you will save money initially, in the long run you’ll be paying exponentially more than if you used Roof Life of Oregon’s clean and treat method. Before you spend any money on zinc strips, read about Roof Life of Oregon’s maintenance process.

Patrick tells us a little more about how moss growth can really harm the roofs that takes such good care of you.

To hear the first part of the explanation go to Moss Growth on a Composition Roof Part 1

Okay, this is what I’m talking about when I say you let the moss get serious on here. This roof will fail two to three times sooner than it should, just because they’ve let this moss form in these keyways, and it will get underneath that shingle and it will lift it up.  Remember, these shingles are designed to traffic water vertically, running up and down the shingle – actually down the shingle.  They’re not designed to handle water trafficked horizontally on the shingle.  Moss, debris, buildup, tree debris, and stuff like that, that will actually cause water to travel horizontally and find fasteners and get into the structure.

Why is moss growth a problem on roofs in the Portland area? Moss growth can cause lifting of shakes and shingles, dry rot, and leaks to appear where water is allowed to get into your home.

TRANSCRIPT: I have a lot of people that ask me “Hey, what’s the problem with moss on a composition roof?” and I wanted to show you this visual of how the moss forms in the little drain areas and then it feeds the spores down underneath the shingle and it actually starts growing and lifting up the shingle.

So, when you get heavy rain, anything out of the ordinary, all of this moss and support system that has lifted the shingle, it allows the water to get to the fasteners and continued water to the fasteners; you see how far the moss has grown up underneath there, continued water to the fasteners, which by the way are right there, you can see where the fasteners are, if water was able to run across this shingle in any direction because it has lifted up, you can see how these are lifted up. That all has been done by Mother Nature by allowing too much moss to form on these shingles, and they just lift them up and then all of a sudden water in getting into your building and you are trying to figure out why. That nail by the way is a low nail, should’ve been up another inch, most shingles put on by most contractors are put on really really fast, they’re paid by the square and then you get one like this where they are put in at an angle and the head has poked a hole through that shingle already and boy if any water gets to that it is just going to leak.

In a perfect situation as long as the shingles are sealed down tight, no problem, but when moss is allowed to form they lift as you can see there, those are lifted all because of moss and this is a very un-mossy roof, the other side of this roof is horrendous.
