Leaks come in all shapes and sizes. Today in Vancouver we were tasked with finding a duroid shingle roof leak. Now it’s not often we inspect a plastic roof vent for leakage when the rest of the roof is in rough shape. But in this case we found what we needed to find. A small crack in the frame on a plastic roof vent provided all the evidence we needed to see. There wasn’t much showing of it but when you know where to look you, chances are you will find what you need to find. Alas, our smoking gun. This little crack was letting in enough water that damage was caused to the drywall below. We replaced the vent the very next day!
