Vent Pipe collars are notorious for creating leaks in roofs between the ages of 13-18 years of age. If you have a leak in your bathroom coming from the ceiling on the second floor unless you live in a ranch it’s probably your vent pipe collar. In the past the entire boot and collar would have to be removed. This is an issue because matching an older roofs shingles can be difficult and shingles could get damaged when removing boot. The roofing industry has made some advances when it comes to vent pipe collars. One Company has a collar that costs a lot more and is alleged to last as long as the life of the roof. It’s only been out a few years and you know how that goes. At CKG Contractors we still install and repair the traditional boot with a couple changes. When we install a vent pipe collar we double up the gasket or the rubber part to protect the flashing from UV Rays. Then we install a bead of silicone around the top of the pipe. Here are the benefits. Pipe lasts 26-36 years at 1/4 or less the cost of the so called super boot and for repair no shingles are damaged. I always prefer the test of time method before we start offering any new products at CKG Contractors Inc.
