Many people think that having a cement tile roof will prevent the negative effects of growth. But I’m here to tell you that it just isn’t true. Portland weather does a number on these tiles and you don’t want to end up with a huge leak in the middle of your house because you didn’t deal with it correctly.

If you take a single tile from a roof with moss growth, you’ll see that it’s actually pitting the tile. As this moss grows and develops, it eats the cement. That cement grit flows down the roof into the closed valleys and creates sandbars. These sandbars lie underneath the tile and traffic heavy rain underneath your roofing. After a few years of this, you’re going to get a nice big leak in your living room.

Tile overgrown with moss


When you walk out your front door in Portland, what do you see on your cement walkways and driveways? Moss growing everywhere! If you let it go, it eats the cement and pretty soon the rocks start coming out. The same thing happens on your roof. So we need to provide that roof with some well care.

Roof Life of Oregon will clean the roof off and apply a treatment to the tiles that will change the pH of the tile to neutral, slightly alkaline. This will prevent blank fungus and moss from growing. Our product also has a hardener that protects your roof from UV damage that breaks down the cement. With this well care, you have a long-term, three-year protection against moss, and a conditioner that helps the cement stay strong. Plus, you as a homeowner have a more beautiful roof on your home.

Roof Life Oregon understands how to manage tile roofs in the Pacific Northwest. Call us for your free inspection and we’ll make sure you and your roof are taken care of.
