Fixing Roof Leaks: Replace Flashing Around Roof Vents to Prevent Roof Leaks

Our Answer

Roof leaks that form when snow melts are not unusual.  The presence of snow on a roof can create what in effect become dams that trap water, sometimes even forcing it to run uphill and under roof shingles.  Ice dams, which form at the roof edge, are the most common form of these dams, but I have seen the condition also occur much higher up on roofs. Fortunately, there is an easy fix to this type of roof leak.
The solution to the roof leak is a roof repair where the flashing around the roof vent is replaced.  This requires disassembling shingles around the area of the vent and rebuilding the roof in this area, shingle by shingle.  Your roofer’s opinion that there’s not much he can do about it is puzzling.  I can only surmise that he is not too interested in fixing the roof leak; hence putting you off.
Fixing roof leaks is totally doable; you just need to find the right roofer.  During replacement, I’d encourage you to look at some of the newer, more high-tech flashing materials.  For example, Grace Ice and Water Shield, and Tri-Flex 30 are two products that should be under your roof shingles to prevent roof leaks.  These materials seal the roof’s under-structure to stop leaks and are designed to work together to prevent the very problem you are experiencing.
