This garage roof was over 30 years old! They had a basketball hoop on it that they removed, but unfortunately, this left 2 large holes in the roof decking that was rotting away. After time, water was going into the garage so they didn't even want to use it for their cars! If this problem wouldn't be fixed soon, they would get more wood rot from water seeping into other areas of the roof decking. So after they called us up we replaced all the rotted wood with CDX plywood, Ice and Water, and new shingles on the entire garage.
