Hip Roof Trim at hip and wall

Return to Installation

Return to Forum

I am the installer/ home owner using ABC's SL-16 panels (snap lock with standing ribs) with concealed fasteners. I have never installed a hip roof before but have done my entire house with regular gable/shed roof ...so am fairly familiar with basic install techniques. My install involves adding on a porch with hip roof to my home.. My questions: I am uncertain how to install the trim where the end wall trim, side wall trim and the hip cap all intersect at the side of the house. Would the hip cap go in last (on top of the side and end wall trim)? Can anyone explain how to do this intersection or better yet provide a picture showing how to tackle? Thanks in advance.

How about some pictures of what you are seeing. We can mark them up for you. Eric Novotny

Here's a pic of the three way intersection in question. The trim that was provided is "L" shaped sidewall, "L" shaped end wall and the 6"x 6" hip cap . All three have to come together at this intersection. I will fill the gaps between ribs with "Z" bar strips, waterproofed w/ butyl tape and caulk.. I called the manufacturer and they really couldn't help me. One guy suggested to put the ridge cap on last (on top of the wall flashing) but it sounded like he was guessing. They couldn't provide any suggestion on how to cut and overlap each piece.

Here is a pic of the three way intersection. The trim that comes together here is an "L" shaped sidewall trim, "L" end wall trim and the hip cap. It's a 4:12 pitch roof. The space between the ribs is to be filled with "Z" closure strips, butyl tape and caulk. The intersection is tight under the gable end eave so it won't get a lot of weather. It is really not visible from the ground since it is on the second story and tucked under the overhanging eave. I am uncertain which should go on last i.e. the hip cap or the end wall trim. I would like to get an explanation on how best to field cut the trim so that it won't leak and look "professional" . Better yet, if someone has a pic of this intersection finished, that would also be great. Thanks.

Folks, I think I might have gotten lost in your inbox. I have replied twice but haven't gotten a response other than a request to send a pic (which I did). I am holding up completing my install . Can you please help. Thanks

I am sorry. I can't think of any photos that I have. Some of these areas you just have to sort of "engineer" as you go but you always been uphill lashings on top of downhill. I would set your Z's first ... start with the sidewall, then the hip, then the top wall. And then put in the L flashings, following the same order. I hope this helps give you some ideas ... perhaps someone else will have photos. Todd Miller

I would run all your counter flashing trim first and then you hip/ridge cap to close off the intersecting hips. It will just run into the wall and if you putting siding on the walls, a small upturn in the H/R cap that intersects the wall and can serve as a counter detail as siding comes over the top of it.
