This episode of the BS* + Beer show is a sweeping discussion about Flashing Details with “big dogs” Doug Horgan, Mike Guertin, Aron Jones, and Bryan Uhler. In addition to sharing a how-to video on fabricating end dams and some visuals illustrating the right and wrong ways to flash, our guests touch on topics that include dealing with wind-driven moisture, choosing products, material compatibility, sequencing and redundancy, horizontal and vertical joints, galvanic reactions, and of course, kickout flashing. Mike Guertin puts the question to the panel: What’s your favorite flashing and why? Tune in to hear the answers and pick up some expert tips.

Enjoy the show!

 

Join us on September 23 from 6 to 7:30 p.m. ET for a conversation with Dr. Jonathan Foley, Executive Director of Project Drawdown, “The world’s leading source for climate solutions.” The nonprofit’s publications, online courses, and programs address the most pressing climate-crisis-related issues. Arguably the richest resource for real-world tactics designed to reverse greenhouse gas emissions, Project Drawdown breaks its offerings into categories that include buildings, land use, electricity, transportation, and industry, among others. Read about the Drawdown Framework, watch “Climate Solutions 101,” and come with questions. It’s sure to be an insightful discussion.

    Bryan made a comment (51:15) about QC'ing the subcontractors work. You can't just assume they know how to do it; you need to walk through it with them, educate, etc. I'm finding that GC's don't want to question subs, that it's deemed insulting somehow. And they also don't want to take on liability from the sub by telling them how to do it. All of which is kind of blowing my mind because otherwise what's the purpose of the GC? I'd be interested to hear what conscientious builders feel their role is in QC'ing subs.

    Mike, can you post a detail of the kick-out flashing you discussed at the end?

      It is a sign of our overly-litigious society that architects have to be careful to specify what needs to be done but can't instruct the "means and methods" of how to do it, and that one of the main reasons you hire a GC is to coordinate and supervise work but they can't tell subcontractors how to do their jobs. I don't have an answer other than societal reform, or seeking out architects/designers and GCs who have a proven record of well-crafted projects. They will be in demand and may charge higher than average rates.

      I wish I had a drawing that showed my detail as I have never successfully described it verbally. Mike Guertin share a slide that was very similar, if you ignore the pile of caulking someone added later. The next time I have that condition on a project I'll try to remember to draw it and post it here.

        I believe the answer to that is 'vertical integration', meaning everything gets done in house, without splitting the project into N different subcontractors, from design, to implementation.

    After watching your show, I found this video about end dam on drip flashing:

    Tried it and works really well and keep the slope intact (the only thing I'm not sure I like is the front corner but I'm sure we can do something better)
