First Cedar shake roof that we have cleaned. Pretty challenging since the gazebo was on 20’ poles. And the roof was pretty steep and moldy. But it turned out!
We have a ton a cedar roofs out here. I have refused to do them as I don’t want to be up there for safety reasons, therefore I don’t want my guys up there.
A few products have been floating around at local suppliers where all you do is spray it on and off. If they work i would jump into the game. Its good money out here that I pass off.
