Metal Roofs - 2 Ways to INSULATE UNDERNEATH!

In today's Video sponsored by Sheffield Metals I'll show you two ways to add insulation to your roof assembly underneath your metal roof. The first method I used on my personal BUILD with rigid foam insulation from Atlas Roofing, and the second method utilizes Hunter Panels which are factory built to include insulation & plywood decking. Watch the video for all the details plus learn how we installed metal on top from Sheffield Metals.

Huge thanks to our Show sponsors Polywall, Huber, Prosoco, Rockwool & Viewrail for helping to make these videos possible! These are all trusted companies that Matt has worked with for years and trusts their products in the homes he builds. We would highly encourage you to check out their websites for more info.

Matt,
You're a fine builder and I realize you only do high end work. My goodness it must cost a fortune to have you build a shed, much less a house. That said, I watch all your videos and learn so much.

Love both roof assemblies. But, putting a layer of zip over the insulation, but under the roof underlayment is probably a little wasteful for someone not sponsored.

Since the first video you posted concerning both your roofs, I have been waiting patiently and wanted to see them done, and by the you set the standard in my book my friend! I'm a born and raised Texan who moved to Tulsa at 18....in 78'. We have a new application for your " pro style " building example as you shared here.
Thank you for raising the bar, and providing the best content ever, so others may benefit from your PRO STYLE
KUDO'S BROTHER,
Seth

Matt, addressing photovoltaics adaptability would have make too long of a video but very interesting and actual topic. Can you include it on a future episode?

[koaea]

Stupid question: when you build in the venting directly beneath the metal roofing (with 1x4s?) Can you still walk on the roof without bending/dimpling the metal panels?

As a software engineer I would be a bit wary of too much technology particularly in something like skylights as it's hard to say how long Marvin will support the tech/app going forward - will it still be viable in 10, 15, or 25 years...

FINALLY!!!! I have been waiting for this video for a very long time. finally i got to know how you did the layers on your roof..
Thanks for the idea! :)

Deleted scene: "So that makes the final thickness of my roof four and a half feet. It's a real bomber roof. In fact it's rated to take a half stick of dynamite without penetrating into the attic."

😂

Best part of metal roofing like that - solar panel mounts clip on without penetration. Worth it right there.

[guytech]

using SIPS for the roof is probably a better option & might be cheaper when the labor costs are included. FWIW: I have 12" SIP panels for my roof, but the 6" SIPs would probably be about the same costs (material + labor) as using the individual Poly Iso panels. Plus SIPS can handle the overhang with out any weird bracing.

I am having this very roof installed on my house this week. I had to find someone who knew what I was talking about. I am very excited to complete this project as when the roof is installed we are immediately following it with a 11.6 killowatt solar install Q Cell panels and Enphase microinverters. Batteries to follow next year.

I love the details Matt put into the roofing and insulation system. Truly creative! Also, thanks for choosing Jeld Wen windows and doors!

[jmacd]

What I'm curious is how do you edge this or Flash it for the sophets when you have that huge foam edge up top

[ninjajoe]

I wonder if it would be possible to put a Pex system into gaps between the wood and metal to capture the heat and put it into a hot water system in the house?

[jwristen]

Using this assembly on every house I build. Thanks Matt

[Scbaman]

Do you have a video of an unvented Rockwool assembly with a metal roof?

[scorpio]

It would be interesting to see how you detail the fasteners of the roof metal over the furring strips.

Im actually trying to figure out how to insulate my house from the outside so I dont destroy the walls inside. I had a weird metal roof installed on my home that has tall grooves on top - about 2 or 3 inches tall every 4 inches.I want to fill those grooves on top with rigid foam insulation cut to size. I need something to cover that, that isn't very expensive and also doesnt need to be screwed or nailed into anything since my roof is metal down below! I don't think I'm going to be able to use glue on a roof lol. How could I do this and have it be safe? If I glue the foam into place, and paint the roof with elastic roof covering paint, will that last a good long time? I live in a mobile home in FL with a really low budget. I just want the AC to rest sometimes, because its running 24/7 in 100+ degree temps.

[JohnGeddie]

How do the large lag bolts and other fasteners impact the insulation? Isn't drilling through 4 inches of insulation creating a metal hole that conducts heat and cold every time (hundreds of times) you do it. Is there any information on this?

[johnpeterdean]

How would you incorporate a radiant barrier into an insulated metal roof design ??? On your house would you put the foil on top of the upper ziplock then put the diagonal frame in place with the metal roof on top ????
