We have a Spanish tile roof and one of the caps and a few tiles cracked over the years. Wilson promptly came out and fixed the problem correctly without any issues. About half a dozen other people have used them and they were also very satisfied.
We had a great experience with them. They did a very thorough job on two separate projects for us and finished ahead of schedule. Professional, reliable, and communicative. They aren't cheap, but I trust that the work was done right.
