Great point on the drip edge, Tom Silva always uses a thumbs width away from the fascia, to avoid the water getting stuck in between the two and causing rot.
as risinger stated in the video, usually you are going to slide the gutter behind the drip edge. in risinger's case, the cor-a-vent acted as a spacer.
@@paperwait9611, Agree, most just use a gutter or don't. Just make sure your drip edge is 1/2''-5/8'' off the fascia to prevent a capillary situation.
Aluminum fascia damn you people and your exposed fascia !! 😘
In my opinion, adding ventilation behind your metal roof is an excellent idea. I never understood that we vent the wall, but not the roof when you receive all you water on it. Take care Matt!
I think it all depends whether your addic is conditioned or non conditioned/vented. In Matt's case having a vapour barrier on the inside of the roof rafters it makes sense, but if you have a ventilated truss addic, not sure if you really have to as long as you use a decent underlay?
@@vik6980 I think adding a vent between the roof and the plywood would reduce water pressure. Therefore, reducing risk of leakage.
how does this affect oil canning though as well as manufacture application recommendations of applying directly to sheathing?@@ducagace1390 trying to figure out how to accomplish this now with conditioned attic and the place we are getting the roof says manufacturer recommends applying directly to the sheathing yet not sure what happens with condensation etc
3:48 the face that Matt gives his subs when they've not done quality work. Thanks for the explanation from Sheffield for the different finishes, and explaining the details on all things needed for a great roofing system.
Out of all the variety of channels I watch on CZcams, I always learn and take something away from yours. Thank you for such good informative channel.
As a solar business owner with over 40,000 installations, I’ll say we always get excited when we can work with standing seam. Its the best roof type for solar and makes far far more sense than solar roof tiles or punching holes in a 3 tab
Being able to just clamp onto the roof without needing to worry about sealing holes is a huge perk of standing seam. That by itself has been enough to make me look closer at it. The decades long lifespan (assuming it's been installed correctly) makes it even more attractive.
Any experience dealing with weird roof shapes? I've seen a lot of newer houses that seem determined to have as many rooflines as possible, and it makes anything other than asphalt a real pain in the neck.
Big ups to the producers, the quality of the shooting and the editing work on this one is really good. Nice work y'all!!
People made fun of my tin roof. Guess who didn't need a new roof in the last 6 years after the last 3 hail storms and high winds from a tornado. I had a large branch fall on the house. No real damage. Couple scratches. Guy down the street had a hole thru his ceiling and roof. He came and asked me about metal roofs after that and I helped him put one on his house too. Metal roofs FTW.
fkn legend
Do you get a lot of noise when it rains?
I hear you. Over here we have a lot of trouble with an invasive species: racoons. They tend to wreck through simple bitumen covered garden shed roofs like a hot knife through butter. So many of my neighbors in the "garden colony" have to repair their roofs almost every year. Except for those that choose a tin roof like me. And it's not even that expensive. I bought the "eco-friendly" high priced version and even then it was only €35/m² ($4/sqft) including work and taxes.
Survived two hailstorms without a scratch before I even had a chance to sheet the walls.
I try to advocate metal roof. Everyone make fun
steel roofs are the way to go!
I bet Kyle at @RR Buildings would love that metal forming trailer
I wonder if he will more to those cool vented ridge caps pieces
My roofer had one and told me what it cost 10 years ago - it was NOT cheap! Coil of metal was over 100K too he said! Whipped a roof out fast though and was done in hours vs a full day - love it!
Great to see it coming together. Congrats.
It's a THING OF BEAUTY, Matt. LUV all the close-up details. Such exquisite craftsmanship!
Thanks Paul!
@@buildshow how much of a difference does that radiant barrier make. Would you notice it if it wasnt there?
It was good to be back on the jobsite with you talking metal, Matt! Looking forward to the next project! -Thad
More Metal Matt!! 😁
Great to see, construction and tips. Always happy to see some great metal work,.. 👍
Thank you so much for this video. We are moving to Texas and I am planning our self build barndo and this was very helpful for roofing.
Great. makes me like our black 24 gauge metal roof we just installed on our new build in Wyoming. With all the snow, hail, and cold it was a great investment.. We wanted a little extra heat from the roof. Done and never to worry about it for 30 years
After yesterday’s hail storm, I’m looking into metal roofing. Perfect timing.
I’ve been installing metal roofs on the houses that I build not exclusively, but mostly over the last 15 years I’ve been in business. I’ve never once had hail damage. On the other hand I’ve seen lots of asphalt roofs to get replaced around me
I have corrugated galvalum, (a steel and aluminum composite).
@@buildshow did you Forget ? I thought you were going to give us pricing? Thx
@@nixaeagle141 this. He lied to us all
@@buildshow I’ve been waiting to see this part of the construction phase of your house. I was hoping you would explain the best practice details for the flashing from the siding to the metal roof.
Just outside of Austin city limits where some hail just hit recently. I would love to get a new metal roof with all the venting details. It would likely help with heat in the summer compared to my current asphalt roofing especially with my poorly insulated vaulted ceiling.
It would be great to see some details on the Coravent and installation.
Looks like a great system, and aesthetically pleasing.
Im so going to make a architect watch all Matts videos on his own house to design my home! With the addition of a interior above ground tornado shelter!
eh, matt isn't the best. he usually solves problems by doing the most complicated and expensive way. sometimes the slight gain for the increase in cost/efficiency isn't worth it. also, keeping all of the different shapes, dormers, level changes, etc, out of the roof will save your more time, money, and effort than anything matt does.
Ice Guard installed onto the eaves (overhangs) is to be wrapped onto fascia and continue at least 2' past the exterior wall and over the heated space beneath. In other words: not just 3 or 4 feet "up the roof" it all depends on how big your overhangs are. When you are dealing with open porches for example you may need 8-10' of Ice Guard or more
I wanted to learn more about that robot. Like, he teased it and then just glossed over it. I haz a sad
most people roofers hand swage the seams. when risinger referred to a "double lock", i don't know whether than means a 90 degree swage of 180 degree swage. both are labor intensive when done manually, with the 180 degree swage requiring 2 passes. in addition, hand swaging 24 gauge steel is difficult enough, but probably ridiculously difficult on an 8/12 roof pitch.
It’s called a power seamer. Not a robot though lol! www.stortz.com/product/freund-seaming-pro-preorder/
@@robertunversaw it is a robot, which some people call a "power seamer". a robot is a machine that automates processes done by humans. the term "robot" is more commonly used in europe.
Search electric standing seam machine. They've been around at least 35 years. So has the pan forming machine. About $4000.00 new for seamer.
Matt:
Talking about all the ways he is reducing heat with this roof.
Also Matt:
I have a black roof! YOLO! lol
I'm also confused by facing the reflecting side of the radiant barrier down, not facing the radiant source..
Black conducts heat but with radiant down heat doesnt transmit through. Still though...
Why the heck would he do everything he has done for energy efficiency then put a black roof on? Also metal roofs with that air pocket behind it will dent like crazy in hail storms.
@@aintquitewright1480
Well on the bright side I have only seen it hail one time down here. :p
(and it was pretty slushy by the time it hit the ground)
but yah..... it seems very few people these days realize black absorbs heat.
I have been to many places and have never seen so many people wearing black cloths.......
@@lgl_137noname6 He didn't explain it.... but kinda sounded like that was a mistake.
I guess he wanted to save time and/or money and is just going to leave it facing down.
Excellent stuff
You and R&R buildings did a couple of shows about post and metal buildings. But, you do a lot of shows about perfect wall construction. With building supplies getting expensive, can you do an episode about how one might go about perfect wall in a post-frame steel building?
Ooooooonnn the build show , awesome haha
If you're going to have any holes in the roof it should be for your solar. Check out Zilla for your solar penetration. S-5! have the best mounting brackets, good choice there.
Cool video! Thanks.
Wasps will love that drip edge spacer..
Great design tips
Heck yes on S5! Solar clamps, glad you are looking at clean energy for that already high performance house! -solar professional
My county had never seen a solar install on a standing seam roof and wanted the installer to DRILL into my roof! My solar folk had to send out an engineer and set him straight - whew! The clamp right onto the seams - it's awesome! The conduit for the wiring - less awesome :(
Just used s5s last week they are great!
Did you use them for mounting solar panels?
Like Brad Gaeth, I'm wondering how you did all your vents. The attic is conditioned, and we've seen the interior of the attic in other shows, so we can tell know you didn't cut corners and vent to the attic :-). I was watching the eves for vents, but didn't see what I guessed might be there. I think a separate show on venting best practices would be well received. In my upcoming project, I'll have a metal roof, and I'm wondering how to do combustion and exhaust air, as well as DWV.
Been watching every step of the house, major house envy. Would love a website outline for each phase of this huge project. Everything all in one place and hopefully any blueprints your comfortable sharing. Can't wait to see the final house!
killing it dude!!!! youve deeply penetrated this vid!
i look forward to the solar install
Matt - I'm in Texas as well... Beaumont to be exact. Getting a black standing seam roof installed and the builders couldn't get approval to install solars with the S-5 clamp. They will have to penetrate and screw to the rafters due to the windstorm codes. Just an FYI...
Matt:
Please provide a close up photo of how your metal roofing is attached to the roof sheathing.
Thank you!
Lov it!
Love metal roofs, also like contrasting this system with the metal roof system one of my other favorite channels, the Perkins Builder Brothers, recently did on their home under construction. I'm just soaking in the information.
For anyone who is wondering: Matt is indeed right. It doesn't matter which way you put on the radiation barrier, as long as the reflective side faces the air gap.
At first I thought he put it on the wrong way, so I looked it up. An ideal reflective body (which does not exist) will neither absorb, nor emit any thermal radiation. In his case, the radiation barrier will get hot due to thermal conduction, but it will not radiate into the air gap, because of the highly reflective surface. This even works the other way around, because any thermal radiation coming from the inner part of the roof will be reflected back.
The air gap itself however will do almost nothing to remove heat by ventilation. There is so much friction due to the small size of the gap, that there will be no meaningful air flow. That's why it is smart to use a radiant barrier, because this way the air gap can provide at least some thermal insulation.
it is the high tech Zinger at it again....only the best for that boy!.....
Very nice roof.
Nice video. Roof looks very handsome.
2 items:
1) There was no mention of seam spacing. A black (I assume) aluminum roof will undergo quite a bit of heat related expansion and contraction and you will not want to have any “oil canning”. Seam spacing and material thickness impact this.
3) Matt mentioned 3/12 for his “lower” slope area but later your guest said 2/12. If I’m not mistaken, 3/12 is really the lowest you want to go on and metal roof that is not soldered or otherwise detailed to perform as a membrane that will essentially leak under some circumstances.
Some mechanically seamed metal systems can go as low as 1/12 pitch. Check w/ the manufacturer's details/ specs
Love the radiant with the black. Black is undo-able without radiant in TX 👍
THANKS! I'm planning on metal (Southern California) DYI (I need to have this be my last roof)
How old are you???
Can you do an illustration of all the layers of your roof? Zip, foam, peal&stick, 1x4, air gap, Radiant, metal roof… oh my! That’s a lot of layers!
I recently did a metal roof - there's no way, given aesthetic parameters, I'd recommend installing anything else in the future.
@Ganga Din you can get any color you would ever want and it's all personal preference but galvalume would look good on a farm-style build.
@Ganga Din do you think that asphalt shingles (which the vast majority of people have on their roofs) *don't* get hot?
black solar panels would actually blend in quite well.
@Ganga Din Yeah, as Dave Wenzel said - you can get a huge range of colors. I have a friend who finished up, before lumber prices went ballistic, some multi-family (apts./condos) spec. 'houses' and the demand for that rough galvalume repurposed look far exceeded anything I could have imagined. But, as far as using metal - I'm a 100% convert and if you do it yourself the costs are not that much greater.
@@paperwait9611 I don't think he was suggesting Asphalt shingles don't get hot - I think he was suggesting that in the realm of metal roofing black runs hotter. Many, perhaps all, major metal sales companies will say the same thing of metals - lighter colors are better in certain climates. Irrespective, one nice thing metal has over Asphalt is far less mass (something like 80% lighter)....I'm not sure what the construction sciences term is for it but a metal roof will 'shed' that heat MUCH faster.
@Matt Risinger You have mentioned a few times about limiting roof penetrations. It appears you have one pipe/flue penetrating the roof. What is that pipe for and what other design challenges did you have with the others pipes wanting access to the outdoors up top? What kind of compromises did you have to make to limit the number of penetrations?
I love metal roofs. My favorite color looks like dark cow dung. I think that color is an attempt to make it look like burnished copper, but I am not sure. Whatever the name of the color, I would say it looks like medium dark bronze color with a hint of green thrown into the mix. It gives a house a really organic natural look.
Burnished slate is the color
Been doing metal roofs for 10yrs.
I had a retrofit to standing seam in 2019.
The roofer got a precut system and they shipped the wrong dripedge, the supplier was nice enough to come out and make it on site , those machines are pretty nice.
The seamless gutter guys use the same material now so you can get a color match without much fuss.
I have a high pitch roof and wish they would have warned me how slick it was going to be, its like a row of slides on your roof. If i had known i would have had them put in some permanent harness anchors.
I went standing seam because not only was it time to replace the shingle but i was planning on putting solar on and i likeed the ridge mount system. No sense in putting 25 year solar on a 15 year roof.
Hey Matt, Thank you as always. I wish you would have shown the detail on how the roof air flow mesh meets the upper wall.
How do you use the corrugated plastic to allow the vapor from the roof to vent upwards?
vapours travel through the air space between the underside of sheet metal and the top of the membrane, then escape at the bottom of the assembly and at the top (soffit/ridge). There are continous vents at the soffit/fascia and at the ridge/junctions to vertical walls.
Here in Europe we do a 2"x2" frame under ceramic tile roofing for ventilation. Although creamic/concrete tiles are preffered here over metal roofing, mostly because they damp noise better.
Also, more contractors are used to doing tile roofs than they are metal, hence the cost factor.
yes, noise is a factor.
Great Video. Have you ever looked at Decra steel roofing?
that roof looks sweet
Great video, would be interested in why a black roof was chosen rather than a lighter coloured one, would it not get excessively hot in the Texas summers?
Outside of paint degradation, my bet is that because of the ventilation behind it and all the insulation under that it does not have a significant impact on heat energy transfer into the home.
Without ventilation, all that energy would go through the insulation. However, the high temperature variance between the well insulated home and hot metal roof will generate circulation through the ventilation system.
Cool Video Bro
I just priced this September 2022 for a 55 square roof. $105,000 for the roof and $18,500 for the air gap framing details. An architectural shingle roof with full ice/water peel & stick came in at $38,000.
5:33 , 6:04 , 6:10 . . . It is required that every cramped material is both ventilated and not under tension. Thank you very much, Mr. Risinger.
Very nice prep work bfore the double seam roof Matt. 👍👏
To bad the double seam work is kinda porly done, not that final touch that we do all the time in northern europe.
This looks lika a DIY job overhere sorry to say.
Matt, with lumber prices moving to insanely high levels are you feeling pressure to move towards ICF builds? Would be interested to hear your take on the lumber market impacting construction costs and how it is affecting your clients/builds.
Your the man
Hi Matt!! So did anything happen to your roof after the hail storm that just hit the Austin area? Any advice on what we should look for and do when we replace our shingle roof’s after a storm like that?
Great and helpful video. I’m seriously considering either building or upgrading a house near the Oregon sea coastline where nearly 100” of rain & sea mist falls per year. Would this be an ideal roof?
great info! could you take a closer look at the details for the skylights? the example on my roof is more so how not to do it...
also any recommendations on how to tie in once a metal roof is installed on high pitch area?
the flashing on the skylights was done incorrectly on this roof as well
@@briarg1485 any details why/how?
In east tx most roofs that blow off you see 1x4 under it catches wind but I’m sure this guy is nailing and screwing the metal down better
I watch a house flip channel where he had to deal with solar panels on an old roof and the cost to replace the roof was several thousand dollars higher due to having to remove and replace the panels, so a new metal roof is the best time and roof type to add solar, otherwise you're better off putting it on ground level scaffolding in your back yard.
That’s one nice roof
Matt, Looking great Brother! I was wondering what you had up your sleeve to mitigate a black roof.
Would you agree that the black looks good, and that the air gap and reflective membrane more than off-set any convective gain?
Hi Matt. Any chance you viudo a follow up on the project that was having the Brombal windows being installed in the cast insitu concrete home?
‘Oooooooooooonnn the build show’
Hi, Thanks for sharing all you do!
Q: How does one keep raw metal cut ends from rusting?
Welll... its Galvalume a mix of metals. They sell touchup paint pens.
Hello team @TBS,
Did you ever consider to allow for a recessed space in your roof panels so your solar panels would be flush with the roof line? This might improve (maintain) the aesthetics of the roof substantially. Post-fit solar panels are an eye sore to many. I appreciate your views on this,
Would love to see a section view of this roof down to the first layer of sheathing, has to be 12 layers of materials?
"Let's Get Going" - Standing seam metal roof is the most solar friendly roofing with the S-5 connector.
Well done again. I have a design-build house coming up in east Texas and I'll present this type of roof to the owner. I'm more of a commercial contractor and your videos have helped me brush up on building houses. It's been since the '80s for me to build houses. I do have a series of videos coming that might fill some voids for people on the building of their homes. Design-build pre-construction, value engineering items. I start off with a series of structural failures and lessons learned for 4 successive weeks. The first video I just published is about a structural failure that resulted in 2209 lives lost. Informative and educational for us in the building industry. Just following Matt's lead, educational and informative.
The roof looks great how many inches from standing seam to standing seam?
would be really cool to see a micro inverter solar system on that roof and the install process :D
Emphase with iQ 7+ micro inverters and NeON r lg panels
Then use iron ridge rail system with metal roofs mounts that would be a killer system
Elon has a solar panel that IS the metal "shingles" that snap in and out for replacement and repairs
micro inverters are lame ....sorry
@@RossMalagarie I was just going to say, every tesla roof should be the norm now. Every house could be self sufficient for power. And not have those awful panels on them .
Good news!
You can buy metal clips that clamp onto the seams without putting any holes in your standing seam metal roof. Then you just put aluminum frames on those clamps.
After all, why pay extra for standing seam if you are just gonna put holes in it anyways?
If you do this vented drip edge detail, I can guarantee you that you will get condensation dripping out of the the Cor-a-vent in the north, and likely intermittently in the south too. You will see it running down the fascia and onto the surfaces below -- not a big deal if over plantings/grass, but it will be a call-back issue if there is a deck or other hard surface like a patio there. And no, the gutter will not catch this if you have not prepared for this. If you have prepared for this, you would need to add a Z-shaped "kick-out strip" made from the same metal as the roof that would get installed onto the fascial as the first step of the roofing process. This kick-out strip will direct this condensation that happens under metal roofs, into the gutter. It gets nailed onto the top of the fascia, and then taped into the roof deck before the Ice-and-water goes on THEN you do the rest of the roofing detailing as described in the video. "HOW DO I KNOW!?" I've made this mistake before!
Matt,
Question for your solar installation video:
what percentage of the total metal roof area will be covered by solar panels?
After solar panels are installed, the color of the metal roofing underneath those solar panels is irrelevant, yes?
Matt, I'm a new home builder and been doing some recon work lately scoping out my competition on arkansas and honestly I'm disgusted by the quality or lack of.
I wanted to reach out and hope that you see this message, I'd love to fly out to Texas and check out one of your home builds to make sure I'm not missing any important details before I embark on this 150 home sub division I'll be working on for myself.
Like the way the roof locks to the drip edge. Curious to see the ridge vent system in person and how it is fastened. Looks good from what you showed.
Hard to find a metal roof that stands up to hail in Texas but that 24 guage just might do the trick especially with that mesh vent system under it.
Has the insurance industry put a rating on it yet?
Great color choice by the way.
The best metal roofs for hail are stone coated steel. They look like various forms of tile roofs
Hi, I'm Matt Risinger, and here's my one-hundred-thousand-dollar, ten-layer roof!
risinger is using his remodel as a kind of sponsorship showcase for different product vendors to display their wares. unlike some, i personally have no objection to it. infomercials can provide useful information.
Bravo, for the air gap. Bravo, for radiant barrier, shiny side down; you're gonna need it because that black metal will heat up on sunny days to a very high temperature; but the radiant barrier will block irradiation of lower elements... to the extend that conduction does not defeat the radiant barrier.
I don't understand the logic behind installing "shiny side down". The natural reflective property of a reflective surface facing a heat source across an air space allows the
aluminum surface to reflect radiant heat back to the direction from which it came. If it's facing down, how is it working?
YES SOLAR!!!!! I really want to see that:)
Coming this Fall!
@@buildshow a passive house and solar that is going to be a killer combo.
That’s my hope too!
I would definitely go with something like 385W LG NeON® R panels with that roof. Most people would not be able to tell you had solar.
Almost exactly what I used on our house and 3 car garage in SE Kansas. I installed ice shield first, 1x4 pt horizontally every 16" up the roof and then the standing seam metal panels. My panels snapped together without hidden fasteners and I did the 1x4 to get the "trampoline effect" when it hails.
Why not close the gap? Even though using a 24 guage metal. Id be worried about deflection and denting of the roof, what are your thoughts? I did alot of shingle work in the past w my contrwcting buss. Jyst focus on real estate
I was hoping you'd discuss "solar strip" panels for standing seam.
I was so happy to see someone actually doing true standing seam. I'm so tired of seeing carpenters call snap-lock standing seam. I hate your metal because it can't be soldered. But your crew is doing a great job. Everything I saw was up to or above current specks. BTW, we(tinsmiths) refer to the two sides of the panel as male/female. Thanks for the vid.
Snap lock is considered standing seam...
But it is not a True Standing Seam metal
All it has to do is have a standing leg to be considered standing seam.
@@peterparker9286 I know. It's just that I have been putting on double-lock, batten seam(with true batten boards) and soldered common flat seam for almost 44 years. I used to work with Terne, mostly. I have done a lot of copper in 16, 20, and 24 ounce. I have done a lot of lead -coated copper and "Freedom Gray". Lately, I have been using a lot of Roof-in-Nox TCS. This is really a very superior product. I think the baked on factory finishes definitely have a time and place, but frankly, if the roof has penetrations and you can't solder the metal, it's junk. Just my old time tinsmith's opinion.
@@calliecooke1817 Nice You know what you B doing. What is this freedom Gray stuff ???
@@peterparker9286 BTW, I should mention that I work in Washington, D.C. and get a lot of historical and government work that require SMACNA specs. Not everyone is so fortunate. Freedom Gray is a Revere Copper product. They started making it in response to EPA cracking down on lead. I believe it's a tin/zinc alloy coating instead of lead. Ages very uniform, nice looking architectual metal. Thanks for your replies. Peace.

How did you avoid roof penetrations for vents? What factor forced you to have the one vent in the back? Or were you able to consolidate all your vents into the one pipe?
With a black roof and the obvious heat generated, have you thought about capturing the hot air during winter? Maybe it could be directed to a heat exchanger to heat your hot water or house? Might as well use it if you can since you've isolated it from your roof.
Is it important to install the 1X4 in a diagonal position? Can they go horizontal as well? Would the orientation creates proper ventilation and drainage if needed? Please advise, my roof is going up and the 1X4 are going horizontal.
For a low slope patio cover, (.5" per foot) what is the best method for adhering fiber reinforce rolled roofing to the drip edge. The mastic I used previously let loose after a number of years, causing rain water to wick back and then under the drip edge. I'm not sure the polyurethane I purchase will adhere any better to the tar shingle roll roofing material.
I'm trying to design a similar roof on my future house and like the idea of air ventilation under the roof. I had originally thought that furring strips would be the way to go but my roof will only be 1:12 and 2:12 pitch. Therefore I may use the ventilation underlayment mentioned in the video. Does anyone know if the roof can be walked on once the metal is installed? Or will it result in the roof deforming/bending because of the underlayment? Nothing lasts forever so someone will eventually have to get up on the roof--I just want to make sure it doesn't deform.
I would appreciate an answer to this question as well
Funny I just got a quote for a metal roof on my small 1000sqft rental house. Shocked the crap out of me at $22,500 for a super simple roof job. Looks like I’m gona wait a while to see if steel prices come down before deciding what to do.
How big is the roof b/c the square footage of your house really doesn't tell me anything about the roof size? Its quite common for a metal roof, depending on material and type, to cost 3-5 times as much as asphalt shingles.
You need to do a video on reducing roof vents.
Yeah, where are the toilet stacks?
@@JerryLevenson
Usually out the gables.
You need to check code in your area to match proper pipe diameter, etc. but the vents aren't required to only go up.
You can't go up, and back down, and you need to size appropriately.
Looks at mountain ski cabins, most normal through the roof straight up vents are at a high risk of getting plugged or torn off with heavy snow falls.
I'm getting ready to replacing my roof with metal, I've been relocating and reducing the number of roof vents where I can. Water heater was moved last month when I replaced it, furnace is coming up.
When you install the CorVent along the edge how are you going from vertical air flow to horizontal air flow when you have sides on the strip. The sides close off the air flow unless you rip the top edge at a 45 degree angle?
Hey Matt, question about your Fascia boards. What did you use for your fascia boards? and what was the size?
I would have expected integrated solar panels into roofing tiles from Matt 😆
Tesla didn't sponsor the show, or give Matt any free solar tiles, so Matt won't be using their product
@@cyclopsvision6370 Honestly doing the roof like this is a better option for Matt. I see this house as a training exercise for the next passive house his team builds. It is better to work with partners that will support you along the along the way with things like installation training.
Solar panels are always changing and improving. A metal roof last 50+ years, while most solar panel systems expire or become obsolete within 30 years. It just doesn't make sense to integrate the two as a single system.
I'm in Florida and ye been warned that those S-5-n connectors are great and I have used them myself, but since they are not connected directly to the rafter engineers are requiring them 16-32 inch on center in high wind areas. In fact Maimi Dade is about to change wind requirements to 170mph and these may not meet the requirement. Just be prepared to install A LOT of them if you are using a rail system. The S-5 can also be used directly to panel w/o rail, but it does not provide enough space between the roof and rear panel and is believed to shorten the life of the panel and may be against fire code.
@@karthik11512 If Matt really wanted to go passive, he would have Tesla's solar roof, and 3 powerwalls, and use geothermal for heating and cooling. It doesn't get more passive and energy efficient than Tesla's solar roof and geothermal, especially in Texas, with lots of sun exposure
@@cyclopsvision6370 thank god he was wise enough to use those tiles. Weve made an outrageous amount of money fixing warranty claims on the solar roof
You had me at Black Metal💀
