Nice video! Informative for sure. We don't use felt, we always use peel-and-stick underlayment. For a while I considered leaving it off if I was using zip system, but we opted for the belt and suspenders approach and using both. It certainly costs more money, and difficult to justify since we build spec homes for sale, but we're proud of the product we take to market and feel confident in the strength of our roofing systems.
When I built my off-grid cabin last year, I didn't use Zip on the sides or roof deck, but I did use Zip Tape on all of the joints like it was zip. No OSB, it was all plywood. I love their tape, both regular and stretch, such a game changer on window opening flashing, door pans, etc. When I build my retirement home on that property, I will use the entire Zip system. It just wasn't worth it for the 3 season mountain cabin, but it's so tight we easily heat it with the tiniest wood stove that is 12" x 10" x 11", but it will easily get it to 85F when it's 32F outside.
Agree that it's worth the investment. Too much stress to try and manage weather and exposed decks. I'm learning a lot on my first, from scratch project, but my next home I'm thinking to do 16 on center trusses and 7/16 zip, or I might still go with 5/8 along with 16 on center. The current one ended up being 24 on center with 7/16 OSB and I don't like that at all. I caught the mistake too late, and it's a low slope on top of that. Likely it will end up metal when it's time to renew.
Agreed, I'd like to also see that! With the new foam insulation products I'd like to see the costs breakdown with few more other types of roof decking products costs comparisons
Ok, great! But do you have any idea how much time is “much longer”? I.e. one crew is done by noon while the other isn’t done till two? Or, how many man hours per square? Just curious. Labor is almost always the most expensive part of a job..
@@pdg9582Well that depends on so many things you can't really say without looking at a specific job. You also don't usually pay subs per hour either although the price you pay certainly has how much time they think it will take them to complete the job factored into the bid.
Have you done any videos about using Zip System on an existing home? I want to update our 1980s modern style home and use Zip on the side walls (and maybe roof) to insulate it better - using the Risenger system of insulation, Zip System with about 1” foam, fur strips and Hardie-style board on the exterior. Problem is my roof overhang is not enough to put all that thickness under… what to do? ❤
Agree with the value, but why not just tape regular OSB or Plywood like prescribed in the Fortified roof standard and accomplish the same goal for less? Even with the Zip the roofer will still need to put down Ice and Water shield and underlayment.
The one thing I ran into with standard OSB is tape doesn't stick to it well. Doesn't matter what brand of tape it is. The raw wood face is like trying to tape to a dirty surface. It just does not stick well. CDX plywood is better, but a complete peel and stick underlayment is going to be better than taping.
I'm a proponent of building like this, but in your example of the roof getting torn off and still having protection, what about all the penetrations that will have been torn out? Nails and screw holes all over, no?
Don't use H clips with zip system on your deck. Huber advises against it as it makes it harder to get a good tape seal and they are unnecessary for anything under a 32" span for the 5/8 zip panels.
How much is a small leak at some point in the life of the roof is going to cost you that could possible be stopped with zip and the tape? I bet you a lot more than $2K. The roof and foundation are not places to try to save money. That is just one advantage.
i'm not sure in your area the labor cost is the same as the cost of all the materials used to build the house not including mechanicals. so i know zip panels are all the rage for builders but to me the added price of material and labor is to much. get some good osb and bicthithane cover the whole roof with it and get the same dried in house for less.
5/8" Zip sheeting here in Sonoma County at the beginning of 2024 is $50 a sheet ?? It's way too high, why has it almost doubled in less than a year, I see a rip-off from Zip company.
You still must sheath zip roof-Huber requires it, damn WTH good reaosn a. These roofs are NEVER leak free. Vertical tape works well if rolled, horizontal is very very iffy-look u r either dried in completely r you are not- carpenters can roll two layers jumbo tex without holding up job waiting for roofers.

I like the sit down style with the mic setup, quality audio, solid work bro
Thank you!
I find the cost breakdown very helpful in making my mind up on what I want to do
Great to hear!
Thank you for sharing this information! Very informative!

At my Lowe’s in Knoxville TN the cost of 7/16” zip sheet is $34, $30 if you buy in bulk

Excellent content, thank you sir!
Great video! New subcriber. How bout compare cost of Zip R vrs exterior insulation over Zip/plywood. Thx

How about labor cost? Does it take the same amount of time to install the tape as it does to install a synthetic underlayment?
No it takes much longer for tape

@@nick21614especially if rolled properly and meticulously and if you dont there si no point in using zip
If using zip R6 for the walls on a project, what would you recommend to use for the roof?
I'm curious about this myself.

Ask Steven Baczek - he's the current guru of designing tight homes.
tape the osb?
Yes, that works. But l'd upgrade from OSB to plywood since it breathes better and handles wetting better. I wouldn't live in a home that uses OSB
@@ArthurDentZaphodBeeb Definitely plywood. I framed in Seattle (rain) and we had no problem keeping things dry.
Agree with the value, but why not just tape regular OSB or Plywood like prescribed in the Fortified roof standard and accomplish the same goal for less? Even with the Zip the roofer will still need to put down Ice and Water shield and underlayment.

As he stated 95%.
Nails are probably less than 1% of the entire roof footage.
The rest has the built in membrane .
Don't use H clips with zip system on your deck. Huber advises against it as it makes it harder to get a good tape seal and they are unnecessary for anything under a 32" span for the 5/8 zip panels.

The roof and foundation are not places to try to save money.
That is just one advantage.
Anyone that is installing any type of osb for sheathing,shouldn’t be worried about anything else.
Did you guys really put h clips on that zip? Doesn’t that go against there warranty? Lol

Why don’t you ice and water shield a osb roof. It’s easy.

He’s sexy
NONSENSE will- you mUST use unerlayment over zip !
