One of the tests we preform for vinyl siding is to pull the larger pieces and see if we can slide it back and forth. Vinyl siding needs to be installed loose because the siding expands and contracts with the changes in temperature.

This siding was tight and I was unable to slide any of the large pieces that I tried. You can’t always predict when or what will happen, but there are chances that the siding will crack/split when it shrinks. It can also buckle and become unconnected when it expands.
