Problem: The previous cricket was poorly installed. This led to water getting into the pitch and corner of the back of the chimney causing build up.
Solution: We were able to salvage the original cricket, reinstalled it properly and added the W Valley Metal. Because the Valley Metal doesn't let anything get in, the homeowner will receive an additional 10 years off of it minimum. Without it, you just have shingles that catch debris and water leading to rot.
