ice shield on damp plywood

[mark2457]

Hi All

Got the roof of my new garage build sheathed (5/8 ply) last weekend. Was hoping to shingle too, but snow and rain meant we could only work one day. We had torrential rain last night and scheduled for more today. I was planning to install ice shield and shingles this weekend, but I don't think the plywood will be dry.

Is it OK to apply ice shield and shingles when the sheathing isn't dry? I assume it will eventually dry from the bottom surface.

Thoughts?

Regards

Knowing the weather you are having, I would guess it will eventually dry? I'm sure someone is going to tell you it will get moldy or de-laminate. But hundreds of Roofs are covered everyday in home construction and I would guess that the Contractors can't afford for everything to be perfect. I'd Roof it and go on!

I'd vote also to roof it now. I do not think it will hurt and I don't think your....my....weather is going to get better any time soon.

I'd be putting some giant *** tarps up there to prevent what you could.

Your "timing" didn't work out . . . . weather is a beyooottttch right now.

Tarp it for the storm. Wait to install Ice & Water shield underlayment when the storm has passed. It will be dry enough by then in few days.

its not going to get any better so I'd put it up now. probably won't stick till next summer. same with the shingles so I'd 4 nail it if you can. imagine the windy city gets some good wind so it will help keep them on till they heat up and stick

Is the bottom side of the plywood exposed/open to the interior of the garage ?

Rent a portable heater (or two) and crank the up as high as they will go. It should be dry in a day or 2.

Bottom side is open right now. forecast for next week is good (3 days with sun in mid 40's and 49 on Sat).

I decided to postpone until next weekend. Will do house wrap, and install the doors and windows instead this weekend

I think postponing it is a good idea, it is usually best to err on the side of caution. But I would keep a close eye on the weather forecast (although they are wrong quite a bit) and if there is more rain in the forecast and the roof is reasonably dry, then put on the ice shield and the felt paper. At least then the plywood won't get drenched again.

Right decision !

I see both sides, But I do know that they roof houses all the time on the coast with the rain and sea mist. Most likely be ok, I would not worry about it.
