Power Washing Your Roof

Not all roof cleaning services are created equal and some may actually cause irreparable damage and harm to your roof. Your roof was not designed to handle the intense pressure generated by a pressure washer. You can see via the photos below, the type of damage that can be caused to your roof when you pressure wash it. So why would a roof company pressure wash your roof? Because the moss and algae living on your roof is a living breathing organism that has become quite attached to your asphalt or shake shingles.

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.


Laundry Soap On Roofs Is A No-No

We’ve had a bunch of inquires lately wondering if laundry soap would actually work on your roof for moss control. Patrick wrote a post on this exact topic back in February 2008 and thought it was important to readdress the topic again. To read Patrick thoughts on using laundry soap for moss control visit the post laundry soap for moss control here.


Zinc Strips – Are They A Waste of Time & Money?

Zinc stripes are the latest invention for fungus and moss control. These very thin metal strips can be easily installed by most homeowners or roofers with galvanized roofing nails. Unfortunately, when water hits the strip and nail it creates electrolysis which corrodes the zinc strip from around the nail heads and this is what you end up with.

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.
