Zip system sheathing *****, my experience (it can't get wet)

[mike93lx]

I used Zip Board on the roof and sides of my 3,000+ sq. ft. shop. Studs were 16" on center. It saw a number of good rains before getting covered. There were no problems at all. Zip Board is a much denser product than particle board. Due to this it holds fasteners much better

Partial board is a completely different product and is incomparable to OSB. It should never be used outdoors.

Zip is OSB with a water resistant glue and a coating on one side

Huber makes Zip and Advantech OSB sheeting. The Advantech OSB subfloors are rated for months of wet time, OSB can deal with being wet and Huber knows how to do it.

Indeed, I used Advantech and it is one hell of a product. Would highly recommend it.

My guess is you are unlikely to see a dime of reimbursement unless you have a written agreement from Huber dated before the repairs were started. From what I can tell building material warranties are not worth the paper they are printed on. If you somehow manage to get the materials without cost you should go buy lottery tickets because it is your lucky day.

They paid out nearly 7k of my claimed 12k, which is better than the nothing I feared. I'll let you know tomorrow about the lotto ticket.

I think you are mistaken when you said the nails heads are not required to be sealed with either liquid or tape. It seems unlikely the instructions have changed since I read them in 2017 to allow less use of the high profit materials, they are in business to sell.

Yes I'm sure. It's in their pdf guide, and here is a quote from Huber's technology manager on JLC: Do you watch Matt Risinger? He came up with something he calls Zip 2.0 where he does this sometimes. Maybe that's what you are remembering?

How sure are you the tape joints were rolled with the required J roller? They do not look right to my eye in the photo with 2 arrows

100% sure, did it myself and was very **** about it. About the arrows, the sheets weren't quite long enough to meet at the rim, so there's a filler piece and that tape is the 6" tape to span both seams. It has since been re-taped after the sheathing was replaced anyway.

Did you build this or hire it done ? If you hired it done, is this the contractor's foray into Zip ? Did he ***** about using the stuff ? How much experience does he have ?

I'm only asking because at a 24" OC stud spacing, I wouldn't ( as a DIYer) ran those sheets vertically. That being said, I wonder if that didn't contribute to part of the problem ?

Built it myself, first time building a house. So yes it is my first foray into Zip and apparently yes I'm bitching about it (I still like the waterproofing part of it). Engineer is okay with vertical sheets. It avoids extra blocking and laps onto the rim to avoid extra steel hardware. It may have contributed to it yes. Staggering is also not necessary for this house. Here is some more reading if interested: https://www.awesomeframers.com/blog/vertical-or-horizontal-sheathing-which-is-right

I have a build thread going if anybody wants more context: https://www.garagejournal.com/forum/threads/build-thread-garage-shop-living-space-in-the-pnw.484343/

Let's turn that frown upside down and make this topic far more productive and useful -

One other thing, Huber calls for a hard rolling of their taping system to ensure the PSA glue bonds well. Their provided roller is covered with little Zs. So if it was rolled properly there should be a ton of little Zs imprinted all over the tape.

Got any pics of that, OP?

Too bad this happened but I think there are some problems with the install. All I can say is I used ZIP when I had my house and shop built in 2009. One of the first in the area. Even had the SIPS panels on my roof fabricated with it. Constructed an addition last fall and used it again...in all cases not one problem.I did hit every nail head with rubberized undercoating in 2009 and with Liquiflash last fall and otherwise followed Huber's directions to the letter.

Antagonistic much? Believe the guy or not, but maybe dial down the obnoxiousness a bit.

Come on over, I challenge you to find a single piece of tape that doesn't have it.


But this is not relevant to the issue I experienced. The warping was not caused by faulty flashing details, but rather the exposure 1 rating of the OSB itself and its ability to handle weather during construction.

I have built a few houses, a few garages and many smaller structures, I have only used rated plywood, nothing else and never will.
Plywood just plain works, period.
These manufactures can try to "dress up" OSB all they want,, but it is still OSB.
I have demo'd 100+ siding sheathing on remodels,, the OSB is always is pis poor shape.

This is not regular osb far from it actually.
Similar like LP smart siding that stuff handles rain, moisture and such with no problems.
I had cut offs laying around exposed with cut edges to all four seasons and nothing happened.
