I was going to suggest the same thing, we had a leak where the roof met the chimney on our house. It was originally flashed, but time makes most flashing fail. Cricket installed and problem solved.Went through a similar situation on our house around the chimney when it was new. After several attempts from local roofers, I contacted A-Best Roofing. They took one look at my issue and told me I needed a cricket. Problem solved.
