A few months back I started a post about an upcoming project to repair a poorly installed lanai roof. I have finally begun the project. It is in 3 parts: 1. A 64' X 11' attached back lanai with about 1/2 of it screen enclosed. 2. A pergola over the spa tub 3. An unattached front lanai All three roofs were made from the Palram Suntuf panels. I will be using the same type of new panels for the rebuild. I have begun with the pergola roof first. I have removed the roof; the rafters and one corner post with a rusted out anchor bolt and tie. Due to the prior owner's not properly installing the roof, rot has set into the rafters where the roof leaked and fasteners were installed. It is not bad enough to to make the beams structurally unsound. I am repairing them with penetrating epoxy, and will reuse them all instead of buying new lumber. I have considered buying a hammer drill/rotary hammer to remove the rusted out anchor bolt. But, I just don't see that as a justifiable expense. It's unlikely I'll ever find much use for it after finishing this. So, I have a 4# smiths hammer and have ordered a pointed concrete chisel and a 1" cold chisel to manually remove the concrete necessary to remove and replace the anchor bolt. The concrete is about 10 years old and is wet much of the time. It's probably very hard by now. Am I biting off too much by trying to do it manually? After finishing the epoxying, I intend to repaint all the pieces before reassembling them. Our Paints are H.D.'s Beher and Glidden exterior paints. Might there be problems with these paints adhering to the epoxy?
