Aluminum siding bulge


New Member
I have an approximate 1 and 1/2 square foot area that bulges when traveling. It has not come undone yet. My plan is to drill a 1/4 inch hole clear through, and secure the siding to the inner wall with a pass thru screw and decorative washer on the outside, caulked of course. Has anyone done this and was it successful in checking the bulge?
