Can vents and roof ventilation are popular topics on our blog because nine out of ten roofs in America prematurely fail as a result of a roof ventilation issue. The location and number of can vents is crucial to maintaining your roof. The type of can vent materials is an important factor too.
Plastic and rubber are two materials that can play havoc on your roof. Rubber pipe flashings last roughly 15 years due to Oregon’s weather patterns. The rubber expands during the summer and contracts during the winter. The result is a pipe flashing that eventually deteriorates well before the roof. Plastic can vents have the same effect.
Plastic can vents have a similar lifespan, but should never be used on your roof. Roof contractors that use plastic can vents are cutting corners on materials in hopes of generating more business as a result of your roofing components prematurely failing. A cracked can vent is a leak problem waiting to happen. Wind driven rain has a direct line to the inside of your walls. Unfortunately, you wont detect you have a leak problem until it’s too late.
At Roof Life of Oregon we never use plastic can vents, only metal. Metal can vents, like their counterpart lead pipe flashings, will last longer than your roof itself. To ensure plastics materials are not being used on your roof, you need to have a roofing contractor preform an inspection on your roof.
