The most neglected areas on the roof, and the most prone to leak..
New age contractors and "Big Shop" middlemen sales operations offer the same sub-par details that don't last. When you hear the touting of "Ice and Water" underlayment or membrane as an answer to any roof leak, just say "No thanks." (Forgive these guys for they do not know any better, but do not use them to install a roof on your home!) Ice and Water underlayments have become a religion and proper flashing details have been neglected. Many of these companies are using modern methods that do not last. We have dubbed this trend "The Underlayment Craze," and a simple search on the internet can yield a lot of information on these issues. Bad specifications for flashings go hand-in-hand with bad roofing field installation practices (like low sloped shingle installation) and all of this can cause leaks, the onset of unhealthy mold and rot.
The same chimney depicted above was never flashed properly and was leaking prior to the new Chimney Flashing work. See before photos below.

In the residential and commercial roofing marketplaces, the vertical interruptions that are the most troublesome are those of the chimney flashing details. These areas are the number one service call request in the industry. They are usually addressed with asphalt cement or caulk by the novices in the trade and they usually leak in the first 1 to 5 years of service. By the time a leak is discovered on the interior of the structure, major damage may have occurred, and the contractor is more than often, out of the business. We get many calls related to inadequate chimney flashings. Word to the wise: It costs less to do it right, even if it costs a little moreā¦.

How do I figure out where the water is coming from on my ceiling?
Water visible on a ceiling rarely enters directly above the spot. Water follows gravity along rafters, subdecking, or wall studs before dropping onto drywall. Tracing the source requires checking attic space for moisture trails around vertical masonry cuts, compromised reglet joints, or flashing splits. Comprehensive building envelope leak inspections isolate active entry points along roof-to-chimney transitions before severe drywall damage or interior mold sets in.
Leaks are caused by poor Chimney Flashings and leaks provide liquid moisture for mold growth. Attic mold under your roof is a serious problem that should be addressed by a mold remediation expert.
