Chimney Flashing
While most companies use black tar to secure the chimney flashing, Roofing Doctor has developed a procedure that makes them the leader in the roofing industry.
We use a carbide saw blade and remove all the existing flashing at the base of the chimney. Then we cut a new reglet in the brick and insert the new lead in place.
The lead is secured with lead anchors, which are driven into the reglet. A joint sealer is used to make the reglet watertight. Before the lead is woven into the shingles, the base of the chimney under the flashing is wrapped with an ice and water shield.
Black tar is not flashing! Any roofer using tar to seal chimney and wall flashing is an amateur at best, and roof leaks will surely result.
Copper chimney flashings:
In the residential roofing marketplace, 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 which usually leak in the first 3 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 more….
Roofing Doctor Never Mixes Metals.
