Sealing house wrap around garage door?

[reader2580]

How does one seal house wrap around a garage door? I am re-siding my garage and the wood around the garage door is metal wrapped. The metal is in terrible condition so I will remove the current metal and my neighbor is going to wrap it with new metal.

tape wrap to flange? caulk?

This is a regular roll-up garage door, not a service door. The service door I watched some videos about how to seal the house wrap. (I am replacing the entire service door.) I just don't know how to seal the house wrap to the trim around a roll-up garage door. There is no flange to seal against.

i'd caulk or tape it. but i wouldnt worry too much about the wrap. the main thing is how well you seal the finished surface.

x2, there's going to be more air infiltration from that rollup garage door than the worst sealing job of the house wrap would ever allow.

House wrap should have an approved tape to use with it. Just tape tight to the jamb.
Siding, depending on the type, might require a caulk joint at the edge where it meets the jamb, might not.
With cement board siding, a 1/8" gap is left to caulk, the rest I'd left uncaulked but has a backer tape at each joint.

This method if good enough for energy star 3.0.

I'm not worried about air infiltration in the least. I want the connection between the house wrap and the frame around the garage to be as water tight as possible so I don't have water getting in there. I really have no idea how a good contractor would take care of this.

I guess no matter what I do it should be better than current. I have badly installed vinyl now with no tar paper or anything else behind it. There is also no flashing around the windows or doors now.

Ideally you have to "dig deeper" and remove the trim and bend the housewrap behind it. More or less the housewrap should be touching plywood/OSB/CDX or framing lumber. The housewrap is a barrier for the framing and sheathing, the trim has to face the weather.

I have a similar setup with vinyl siding applied directly to OSB on my existing garage, I didn't build the original construction but discovered this when raising the garage door header in the wall, as I stripped things back.

I had stained and slightly rotten OSB on one upper corner of the upper garage door, this is 17 years after the original build. However that was caused by the horizontal J-channel of the vinyl siding, on top of the garage door (rollup door) opening having no "tabs" bent down over top of the vertical J-channel. There was basically a 3/16" gap at the transition and water ran merrily down behind the vinyl every time it rained. The siding guys must have missed that day in siding school.

For now I siliconed this up to keep the new sheet of OSB dry, but shortly, it will be an interior wall and the transition will be moved to another spot.

This!

On my new construction, customer always sees a bit of house wrap inside the garage next to the back jambs. This is because the face of the osb is wrapped and the hose wrap continues around the framing and ends inside the garage. The jamb simply installs over the wrap.
If the house wrap is cut, Tyvek tape is used to cover any exposed wood.

I'll have to see how hard it will be to pull the trim off to get the house wrap behind it. I suspect it won't be any fun, but necessary to do it right.

i've framed a lot of homes. you're overthinking it a bit. just **** the house wrap to the edge of your trim and either tape it(rubber butyl tape) or caulk the wrap to the trim.
what you really want to concentrate on is your finished surface. if you have vinyl, well, it will not be weather tight no matter what you do. maybe caulk the j-channel to the door trim.

The siding will be Smartside if it matters. I have been unusually busy with this work this week and unable to investigate if I can remove the trim around the door to do it right or not.

No siding is totally water tight forever which is why I want the house wrap to be installed properly to shed any water that gets through the siding.
