While replacing a shingle roof system, most roofing companies will try to avoid these areas like the plague. The problem with that is that chimney flashing’s represent a very large percentage of leak calls reported by homeowners each year.
Why? It’s almost never replaced when the roof is replaced. That’s because most chimney roof flashing’s are stapled or fastened “behind” the siding at the chimney.
To replace the chimney flashing, means removing the chimney siding. No one wants to do it.
