Today’s leak surprise was in New Westminster when we found a gooseneck roof vent on a tar and gravel roof that had been sitting in water for many years. Now this roof had settled quite a bit and the roof drains were all around the outside edge so we knew it was going to hold a bit of water but the water line showed us it was about 2″ deep! It was the only protrusion around the leak area and the rust around the base was noticeable. Well maybe not noticeable…. how about SEVERE. The erosion power of that water level rising and falling on the galvanized metal was intense. Once we got the roof dry enough for me to inspect the base of the vent it was obvious. Just the attempt of scraping off the loose rust caused it to crumble even more. Now I know why my fingers shrivel-up the way they do when I stay too long in the bathtub.
Today’s challenge proved it doesn’t have to be a roof system deficiency to cause a water leak. When we first arrived to this New Westminster Strata complex we measured the interior drip location out and found the area on the roof most likely. Everything looked great. Couldn’t see a potential issue anywhere on the roof. We double checked our measurements, located landmarks to ensure the correct positioning and always came up with the same location and same result. The roof was tight BUT it had to be something near by! To make a long story short it turned out to be a 4′ section of blocked downpipe, due to someone crimping it unnecessarily at the base so the elbow could more easily slide on, that was backing up and entering into the ceiling space. This is another one I’m proud of because it sure wasn’t easy to find or likely to occur. Persistence pays off and I never say quit until I know I’ve found the problem or the most likely culprit therein.
