How do you seal the hip joint on roof shingle jobs?

I used to wrap the shingles from one plane onto the other when 3-tab shingles were common and then just apply the cap shingles.

Laminated shingles bulk-up when they're lapped over the hip so instead for years we'd apply a 10 in. strip of #iceandwatershield and then cap shingles.

When we capped this hip last spring we tried @protectowrapcompany Roof Edge Seal instead of the Ice and Water figuring the double-side adhesive would not only seal the hip joint but also help bond the cap shingles to the roof.  And they did.  We struggled to strip the cap shingles off.
And it appears that the tape also helped reduce the amount of tear-through the roof sheathing did when the hip got crushed by the tree. There was only one puncture point where a limb punched through.

Even though the Roof Edge Seal didn't bond when we applied it at 17F, it will when the temps get into the 50's and the sun hits the roof.

@jlclive next Friday and Saturday @addison_16 and I will be showing how to use Roof Edge Seal at strategic locations on a roof to make the shingles resist high winds and hurricanes better And where to apply strips of Ice and Water Shield to prevent water entering a roof even if the shingles are blown off.  Stop by the #roofingworkshop on the upper floor of the convention center.

    Thank you for your honey tips🙂

    I’ve never known wind driven rain to push under a hip that wasn’t vented. I don’t think that is a bad idea by any means but I don’t know if I could justify the cost. A nail with proper decking embedment through the double seal tab area of a 3 tab, cut tab or hip and ridge specific shingle does just fine. I work in pretty high wind load areas too, traverse city mi, mostly on homes on peninsulas and bluffs.

    Preferably 6' of ice and eater shield at eaves + full deck armour. 6 nailed Timberline shingles and timberline ridge caps (They come with specialty nails) No call backs, good night sleep. @gafroofing

    Mike, it just occurred to me that I have no interest in roofing, yet when you're teaching, I'm listening. Always great content, thanks for sharing.

    Your book on roofing under Tauton Publishing is what I used to teach myself how to roof. I also used an article you did on valley flashing for the same. Will probably come back to this if I get hip this season. Always appreciate your insights.

    @butchpalaza Thanks Butch. I'll have to do some Trex decking videos - then you'll be interested😂

    @kwallis11 Thanks

    @mtl.missives Great to hear you picked up some useful information. I wish I could redo the roof book. It's dated now. Almost 20 years since I wrote it.

  • 4w ago mikewith28 mikewith28

    Yup Mike knows😉

    @mike_guertin that would be great. I would definitely buy it. One area I found hard to find detailed information was flashing the chimney, if your considering updates for a second edition. Probably the part I struggled with the most.

  • 4w ago mike_guertin mike_guertin

    I did an article on retrofitting flashing into a brick chimney . Not sure if it was in @jlconline or @finehomebuilding . There was a good article by a roofer in FHB just a couple years ago too.

    Great video and use of additional protection 👍🏻👍🏻

    Very good tip! I’m doing a roof now with a few hips. I’m going to use this technique. Keep them coming!

    @miigueliito2348 what mph zone are you in? I've had double nailed caps blown off in hurricanes Bob and Gloria so I'm more cautious than when in my 30s

    Thats a waste of time and money. Hips never leak. I like to see a little ply on both sides.

    Oh that’s a good idea for a JLC topic! Nice work👏🏼

    Like that idea. Must be easier in the winter. Sticky as hell in the summer.
