The Roof Life Treatment

Aerial View

This is our thirty-fourth year in business. When we started all those years ago, there weren’t very many choices for roof treatment. Through trial, error, and experience, we’ve found a self-cleaning treatment that not only cleans your roof but also extends its life as well.

In the beginning, we were mostly working on wood roofs, and we worked with a product called pentachlorophenol. It was toxic to fungus, mold, and mildew, but it was also really toxic to our environment. So we wanted to get away from that.

I then found a product called zinc naphthenate that would keep the moss from growing back for about five years, which was amazing. The problem was that you had to prep the wood to apply it and, as the wood ages, you can’t do that without ruining it. So I started looking for a product that didn’t need any preparation.

Dennco LogoI found a company called Dennco Chemical. They were working on a product that self-cleaned wood roofs. At first, I thought it was too good to be true. So I had them do a couple of test roofs and watched them over a year. Sure enough, it cleaned them off slick as a whistle. The rain activates the product and removes the fungus and moss.

The unique thing about the Dennco products is that you don’t have to scrub the roof spotless. We aren’t going to go up there and scrub years off of your roof. And, believe me, we’ve seen way too many companies do that. We can clean the roof with our specially-made machines, but they are gentle enough not to take years off of your roof’s life.

We’ve really come a long. In fact, we’re the only company in Portland with the rights to these self-cleaning roof treatments. Our goal is to create a strategy, unique to your roof, to help it look good, work right, and last longer.
