Finding roof leaks is not an exact science. In fact it can be downright frustrating to find a roofing leak for home owners and roofers alike. So it’s a nice treat to find the “smoking gun” of proof on your first suspect choice. It’s even nicer when you make the call from from the ground. Such was the case in Burnaby BC today. Concrete tile roof leaking over the bedroom in the NW corner of the residential home. We get to the site and the only possibility in that corner of the house is a plastic roof vent. Now experience has taught me these are a habitual leaker too…. but I want to make us look good so I don’t really talk about my age. So I make the call and prove it to the home owner 10 minutes later with the warped flange of the vent in my hand and a photo in my camera. I wish I could have gotten as good of marks in Science 101.
