Matt, big fan of your channel. One thing I would love to see are cross-section detail drawings showing exactly what you are talking about for us visual learners. Cross-sections of your walls, roofs, and the wall/roof union of your monopoly framing.

[@johnwhite2576]

matt you REALLY need to discuss the details re soffit air intake into that Hunter panel and ridge venting as well as how to attach roofing material-metal OR shingles -also please clarify -did you run brown zip on roof first (ie under first layer of foam ? otherwise how do you achieve air seal on the deck ?

[@chrisclotfelter434]

Good comment. Have same questions.

[@JM-fx8qv]

Me too Matt. Would still need some soffit and ridge vents to draw a convention air flow. Similar venting if using metal roof with the wood slats arranged angular to the ridge.

[@tomjudt]

I have to agree with these other comments Matt. It seems to me that, other than having an additional radiant barrier with the top layer of ISO, the venting channels which are intentionally left open to ambient temperatures, nullifies the work done by the top sheet. I even have to question whether or not airflow through these venting channels might actually create a wind chill on cold days reducing the efficiency of the bottom layer of rigid foam. With the amount of radiant heat reduction we can now get from lighter colored roofing materials, I think this technique might be too costly for any benefit it might provide. Actually looking forward to you proving me wrong.

[@AmandaComeauCreates]

He used foam backed zip on the roof. Most zip is sealed on seams with their proprietary tape and he used butyl tape where he knew future fasteners will pass through. That's his vapour barrier. Everything is built on top of this layer for the roofing. And then he's using Rockwood in the attic for insulation.

[@andrewlewis9266]

I had to rewatch this cause I really like the idea of it. It looks like (and he mentions 2” soffit vents) he vents the soffit and the I would assume you leave a gap at the ridge. It would get covered by the metal roof cap - or ridge vent if you were shingling on top. I think from an affordability stand point, you could reduce the cost by not adding the middle layer of polyiso, and just use zip roof then the Hunter Panels.

[@kaleign]

Really nice explanations with references to past techniques and how you've improved this approach with experience! Great video.

[@markb8486]

Matt, Really have been enjoying your videos and sharing of knowledge. One of you last comments on building houses to last potentially centuries is really what builders should be trying to achieve.

My wife and I recently bought a 50 year old home. It really breathes which I don’t like after seeing your videos. I wish I could seal it completely but I don’t have a setup where I could bring fresh air, on our terms, inside. This is really helping me though to think of the small things I can tighten up and also considerations as we are saving, long term, to build our own home.

[@dlg5485]

Excellent! This is the only way to go if you want an heirloom home that will be supremely comfortable to live in and last for generations with little maint. That's exactly what I want so I'll definitely use this framing/insulating technique when I get around to building my dream home for retirement. I'm considering retiring to the Austin area, so maybe you can even build it for me, although I plan to do a lot of the work myself. Unfortunately, I'm not retiring for at least a decade so hopefully you haven't retired by then!

Matt I am so grateful that you made this channel and share your knowledge. I have learned many things that I never gave much thought to before. I really like this roof system. But on top of your stick down layer still needs to have something on it before the metal. The rain screen Brillo pad wounded fine. Without it the metal will still burn the stick down layer. Remember the other brand that said it was good up to some crazy temperature but when you went back to fix something on the roof and pulled a piece up it was burnt and dried up because the metal was right on the peel and stick. Hope to here back from you.

We're currently in the process of cutting off our overhangs & installing rafters over existing roof. Along the way I'm having my framers insulate the roof as well. I wasn't sure if I was putting together a good plan or not, but based on your videos it looks like I'm essentially doing insulated monopoly framing with overhangs.

I’m surprised your fasting the metal to the plywood. I’ve been doing metal roofs here for the last 12 years or so and we always install 1x4’s first. It’s amazing the pullout strength difference in screwing into plywood versus 1x4’s. We’ve had to do a lot of repairs on other roofers roof installs who just fasten to plywood. What I’ve seen happen a lot is the screws start walking out after 2-5 years. Have you had a problems with that Matt?

[@saticharlie]

I did a «perfect wall in my cabin» : sheating is a permeable wood fiber board (R4) and i have a rigid foam layer (R9) with the air-water barrier membrane already glue to it. Technically, it is R13, but even if it is not finish with no inside insulation, everybody is surprise by how warm it is (ans silent). A lot of folks were telling me i was crazy (what no vapor barrier???), i will just put R13 inside, in de 2x4 frame (that are inside the timber-frame) with no vapor-barrier, only rockwool + gypse panel, so the beautiful timber frame will still be visible. So the total is R26, but R26 with R13 of rigid «outsulation» is really not the same as R23 with only insulation inside. Thanks to Matt, i was new to construction and i started with something close his Houston house...

Fabulous innovation, Matt. You're a true Pathfinder. I'll never forget that roof job I helped with during a long summer heat wave in central Texas (1998). It was my job to climb into the attic and repair a few rafters. The temperature was so hot, I was sweating profusely, and I couldn't hold onto tools because they were all wet from sweat streaming off my face onto my hands. My best guess: it was >130 F. in that attic! We got it fixed, and at lunch I must have downed a gallon of lemonade! Later, I shared some very preliminary ideas with folks at Habitat for Humanity. I'm thrilled to see you elaborate the crucial details. p.s. I recently did a very rough "parametric" analysis that went like this: if proper attic venting saves an average of $25 per month in AC power, that's about $100 during 4 hottest summer months x 20 years = $2,000 saved x 1 million new Texas homes = $2 Billion USD saved by this one invention, in Texas alone! Now, extrapolate to the entire USA, then do same in Asia, Europe, Africa, Mideast, Australia and South America. The potential market for this one invention is ENORMOUS!

That hunter decking IS the secret sauce in this. Bonded like that makes it all possible and not using purlins ("the 1x4 method") means you can use standing seam roofing which is so much better than a metal roof with THOUSANDS of holes in it. That hunter panel would also lend itsend well to the same framing and an engineered purlins system with overhangs and just a screw down metal roof like a pole barn. Unfortunately you would have to seal it all up like an old open eave house to keep varmits out but the envelope would be tight for the house.

Question: Why not just build with standard rafter overhang, but sheath the bottom of the rafters with zip (so not exposed) and then tape facia to that sheathing and that sheathing to the wall. Still air tight - and less gymnastics for overhang. True - tails will not show - but its a better construction than exposed tails for durability anyway.

Hi Matt, keep up the good work! Love the videos. I'm about to do this to our house once we strip the shingles and paper, (we're going replace it with a steel roof ). Our home is one of the first solar envelope homes build in New England in the 80ies. (gambrel roof). Question: my roof decking is plywood, after changing any boards that are bad, what do I do next before using this Hunter product? Do I put a membrane over my existing plywood? More insulation? Keep in mind that because it's a solar envelope, the space under the decking is connected to my north and south outer wall and not conditioned space. However, the heat we lose to the envelope escapes thru the top, so air seal is important. Any tips would be greatly appreciated! P. S. This might be a candidate for one of your videos.

Northern builders might also want to keep the strapping under the metal roof. We get a lot of frost and condensation on the bottom side of our metal roofs that needs to dry.

[@bryansweeney4562]

Norther builders may also want to consider the snow load on the overhangs. Austin TX doesn't get much snow but, where I am in NH, overhangs like the ones Matt is installing would have to carry a significant amount of snow load, especially in the spring when the snow is melting and can gather at the edges. I don't think a mechanical fastened 2x supporting the overhang would fly with a NH structural engineer.

But it looks like you have the Shark Skin underlayment completely sealing the ridge, will you be cutting that open when you install the metal roof? Also a little surprised that Hunter does not add a radiant barrier on top of the polyiso. Seems like in a hot and sunny climate a foil film under that air gap could stop a lot of heat from being radiated further into the structure.

[@MichaelM-to4sg]

You create a chimney stack along entire ridge by cutting the top plywood sheathing 1” short of ridge. You cap it with a slotted z-flash and stand-off ridge cap. Very easy and common w/standing seam roofing. It’s recommended to run reticulated pu foam behind z-flashing to prevent insects, 30 or 45 ppi works great, is widely available and cheap.

[@bluenadas]

Thanks Mike but that is a roof peak detail. And an interesting one. But I think the eve venting leaves a ton of room for innovation and architectural play. I'm thinking a false fascia with a gap (filled with bug proofing) or a gap at the wall/rafter interface. Like I said how the air gets in and out could be fun. The fact that it needs to is always there though.

[@MichaelM-to4sg]

@@bluenadas I would cut the foam 2” short on end the cantilever 2x6 off siding , cut the ends at roof pitch and nail 1x6 fascia. I’d then run the SIP top deck over the fascia either top screwed or stapled. The drip flashing over that. On the underside, I have a soffit that I fit 1x material w/2” screen or louvered intake along entire length of soffit.

[@bluenadas]

@@MichaelM-to4sg I like that idea but want if you wanted an open soffit design like Matt enjoys with nice cedar rafter tails? I’m thinking foam ends at the wall and you rip cut about 5” of a 2x6 3/4” deep to be flush at the SIP decking but allow an air gap at the wall/SIP interface. Filled air gap is hidden in shadow and the style of the open soffit is maintained?

In Zone 5 vapor barrier depends on multiple factors, will you have AC, is your insulation permeable, do you plan on having exterior insulation. If you answer yes to all three questions above then you want the vapor barrier with 2/3 of the insulation outside the vapor barrier. That keeps water from condensing in the wall assuming interior is 70 degrees and 40% humidity and exterior is above -5 degrees and this system would not be a good idea. If you are using impermeable insulation, like the poly-iso in this system, then the insulation would be your vapor barrier making this system ok as long as there is continuity between panels and no airgaps where vapor can bypass around the insulation. Details are important. These are my opinions and further specifics should be investigated by a local professional.

Interesting! We created a full foam envelope on the outside of our house, but sealing around the metal rafters has definitely been a challenge! 😄😎🏜️

Hey Matt, can you cover not forgetting to remember to plan for internet technology as part of the electrical plan? I've run into 3 people this week alone who had to retro-fit ethernet wiring and extra outlets into their finished new builds to get proper coverage.

My old house needs a new roof. I was thinking of adding foam to my roof before the new roof. Do I need to plug all my attic vents?

How will space above the insulation do with condensation ?

[@ljn1234]

All that sealing and taping and what-not and then you have to send fasteners through the whole thing. I assume the system dries on the inside but have you had any issues trapping moisture in that assembly?

Would this roof system work for a colder place in canada ?

What is the link to the Monopoly Framing that you said you shared? I don't know what Monopoly Framing is. Thanks.

What did you do about the sewage ventilation?

[@robertsmith-gillespie4009]

With these really tight houses, it becomes necessary to add controlled air exchange. Can you do a show on air exchange technologies? It would be good to understand efficacy and costs of air to air heat exchangers. Thx

Can you do a singled roof on these hunter panels?
