Making Sure Roof Penetrations Are Watertight

By Alec Doniger. 

Take preventative measures to avoid leaks after installing vent pipes, chimneys or anything the penetrates the roof. 

Although we are all roof lovers here, it remains a fact that replacing one is not simple. It requires skilled craftsmanship and an understanding of how water behaves when it is traveling across the roof’s surface to the gutters. If it has a chance to enter a home it can slowly seep inside, often undetected, until the homeowner spots telltale signs of the leak.  

Damages from a leak can be costly and time consuming. That’s why it’s important to get the replacement right the first time. Part of this means that all roof penetrations must be carefully sealed and protected, becoming impenetrable to water.  

Pipe collar failure is extremely common. It is one of the most common reasons why roof leaks begin. Most pipe collars are made from materials that wear out before shingles do. The experts at Wil-Mar were tired of dealing with failing pipe collars and felt that home and building owners deserved better. To solve this problem, they developed a pipe collar made from EPDM rubber.  

EPDM is more durable, resisting cracks and deterioration for the long-haul. Wil-Mar’s EPDM pipe collar will last the lifespan of the shingles, won’t crack or split, and stand up to the elements. If you’re responding to a leak call and discover a worn-down pipe collar, Wil-Mar has one of the best options for your replacement. 

Now that the penetrations are protected with reliable pipe collars, it’s important to double check other vulnerable areas, such as chimneys. The chimney might be protected with aluminum flashing, but to further protect this penetration, you should apply a sealant around its perimeter. 

Products like Through the Roof! by Sashco can make a big difference in ensuring leaks don’t occur at penetration points. This sealant will protect the roof in all types of weather conditions. It can even be applied to wet surfaces or in freezing conditions.  

By using durable, weatherproof pipe collars combined with long-lasting and high-performing sealants the roof should properly protect the home for years to come.
