Plastic roof vents may seem durable, but over time, they become brittle and crack, leading to leaks. On tile roofs, this is a common issue, especially when the vents were originally sealed with mastic. As the mastic dries out, the seal weakens, allowing water to seep in and cause damage.
At Aldergrove Roofing, we take a better approach by replacing old plastic vents with hot-welded metal vents, ensuring long-lasting performance and superior leak protection.
Why Plastic Vents Fail
Brittle & Cracked: Exposure to the sun and weather causes plastic vents to weaken and break.
Dried Mastic Seals: The original sealant can dry out over time, leading to leaks.
Poor Fit with Tile: Plastic vents don’t always sit flush with tile, increasing the risk of water intrusion.
Our Solution: Hot-Welded Metal Vents
Durable & Weather-Resistant: Metal vents last much longer and won’t crack like plastic.
Better Water Protection: Instead of relying on mastic, we bend a containment lip on the vent, preventing water from getting inside.
Flush Fit with Tile: We notch the tile so it sits properly on the vent, ensuring a clean and secure fit.
By making these upgrades, we eliminate common vent-related leaks and extend the life of your tile roof. If you have old plastic vents that are showing signs of wear, contact Aldergrove Roofing today for a professional inspection and upgrade.
