I agree with Brad. There is no flashing on the chimney. The chimney should leak after one or two summers when the sun dries up there caulk. The picture shows that the lap is far enough but it looks bad because the overlaps are different on each row.

All aspects of residential Roofing. This includes shingles and flat (low slope) roofs. I have knowledge in the installation as well as the design of roofs from an engineering standpoint.


I have been doing roofing for 40 years. This was my father's business and I took it over in 1980.

I have written responses to artcles that I felt needed a response to and those responses have been published in roofing trade magazines.
