What happens if a tile breaks on my roof after the installation of foam insulation?

After the installation of spray foam your roof is bonded together into a continuous structure, this greatly reduces the chance of tiles breaking from impact damage etc. However, should a tile break for any reason it can be removed and replaced in the future, it just takes more effort than normal. We recommend cutting out the foam from the area of the tile and removing the tile from the outside, after replacement the tile can be sprayed back in place with foam.
