In the Code’s Eye View section of JLC, code specialist Glenn Mathewson, took a look at a 2012 IRC provision that allows the use of continuous flashing at roofing-to-sidewall intersections as an alternative to traditional step flashing. The provision is short on installation details and requirements, so we asked Mike Guertin, who leads the roofing demonstrations for JLC Live to give us his take on installing continuous flashing, which he has taught in his classes since 2002. Here’s a look at the complete installation sequence for two continuous flashing methods allowed under the building code. Bear in mind that while Mike shows us how to get it done, he still prefers step flashing – a tried-and-true method that remains best practice regardless of what the code allows.
