I recently had a new roof put over the back deck. We used the normal Laser lite roofing but it makes a lot of noise all day as it expands and shrinks in the sun. I had this stuff up there before and it was only about 7 years old. it didn't carry on like the new stuff does.
It was attached using those self drilling screws which have a cutter just under the screw head. They cut a larger hole than the screw itself so it isn't that the holes need to be bigger. There is plenty of room around the hole for expansion. I was thinking that maybe it needs to be tightened down a bit more. Any thoughts before I get up there and have a play.
