Faulty flashing causes leaks on your roof and is among the most common problems that can arise with a chimney. There are a couple of tricky aspects to flashing. First, the leaks caused by faulty flashing often go undetected, but can result in severe, costly damage. Secondly, the installation of flashing requires a certain level of skill in order to achieve an effective waterproofing seal between the chimney and the rooftop. Our trained technicians look for signs of problems with the flashing during chimney inspections, and then properly repair and replace flashing.
The flashing consists of the metal panels at the base of the chimney where it meets the rooftop. The base, or step flashing, is installed underneath shingles, lies flush with the roof, and bends upward against the chimney. The second part of the process involves counter flashing. This piece is bent down over the step flashing and is embedded into a chimney mortar joint at the top. Its purpose is to keep the top part of the step flashing waterproof.
The corners of flashing tend to be vulnerable; it is often necessary to ensure the waterproofing aspect of flashing with high-quality urethane caulking. However, caulk cannot fix a problem of flashing that is improperly overlapped.
Leaks caused by chimney flashing are not always immediately evident and therefore can cause serious structural damage. The roof, attic, and ceiling can all be damaged when moisture enters through the faulty flashing.
Moisture can wreak havoc on your chimney in more ways than one, which is why we often install a cricket or diversion roof which diverts water away from the chimney and flashing.
