I have clients all the time who say to me, “I can’t wait to get out of this cedar shake! I’m going to go to this composition style roof and it’s going to be awesome. No more maintenance!”

Unfortunately, that’s not the case. There is not a single roof on the market that doesn’t require some type of maintenance, including asphalt.

You’re going to have just as much maintenance with asphalt as you would with a shake, if not more.

I remember when I first moved to Portland in 2002. I saw all the moss growing over the old bridges and thought it was cool. Later on, I would learn how big of a problem moss really can be.

When moss grows on your asphalt roof (and in Portland, it will), it eats it away. Some of the literature on composition style roofs can be a little bit confusing, because it will say “algae resistance.” Does algae help promote moss? Yes, but it doesn’t need it to grow.

People see “algae resistance,” and they automatically think all the green stuff is going to be gone. But it’s just not reality. You will have to do some type of maintenance.

The best thing you can do is keep the debris off of your asphalt roof. And then give Roof Life of Oregon a call. We’re going to make sure your roof stays healthy. And you can rest assured we’ll never prescribe something your roof doesn’t need.
