I took some time this morning and investigated more the area that I have little idea how to fix. This shows a larger picture of the area where the 1/8" (NOT 1/4" luan) has popped up.
I peeled a little bit more of the luan up to realize that there is no support along the outside edge of the rv. It rests on the metal joists with no support front to back. Unless you count the 1/8" edge of the metal frame, which provides a little support but no place to glue them together.
In this view I'm holding the luan up. The foam insulation seems to be puffed. Maybe from water damage but it is too big to allow the plywood to rest evenly down.
Here the picture shows the luan lifted up by the insulation and way out of alignment with the siderail and neighboring luan.
Most of the luan I've seen or used isn't plywood, in the strictest sense. As Tom said, plywood is made from multiple layers of thin sheets of wood pressed and glued together with the grain alternating direction. This gives plywood its strength. Luan typically has a solid core material sandwiched between two layers of veneer. RV ROof Repair
ReplyDeleteMy parents have a trailer. I hadn't really given much thought that this roof would need to be kept up as well as a normal house. Does it take long to do?
