A Leading Cause of Residential Roof Leaks

By Karen L. Edwards, RCS Editor.

Pipe collar failures are one of the first suspects when it comes to water infiltration.

Asphalt shingles are designed to last 25 – 30 years, protecting a roof. Unfortunately, the typical pipe collar does not last quite so long. Deterioration over time and in some cases, poor design and materials can lead to failures.

W.R. ‘Bill’ Merrin was a roofing contractor who saw firsthand the failures of traditional pipe collars as well as mastics and tapes. He knew that there had to be a better solution but could not find one. So, he did what most craftsman do when they are tackling a problem, he developed his own solution.  Bill started Wil-Mar Products where he invented and patented The Pipe Collar, an EPDM rubber collar that slides down over the vent to form a watertight seal that is guaranteed to last the life of the roof.

That was nearly 30 years ago and feedback from contractors has been great. They really like that the collars are made from EPDM which keeps them from deteriorating and cracking. We have heard from some contractors that they are stocking their service trucks with The Pipe Collar because so many of their service calls are related to pipe collar failures. Having a reliable replacement option in the truck provides a quick fix for the problem and a fix that contractors know will perform and last for the remaining life of the roof.

Available in six different sizes and selling for just a couple of dollars each, this is an item that you can’t afford not to have in your service toolboxes. They are available by the case, ranging from 100 to 500 in each case (varies based on size of the collar) so a few cases is all you need to outfit your crews with this easy-to-install, flexible and powerful watertight collar.  If you don’t think you need a case, lesser quantities are also available – just ask!
