Framing and Sub-Flooring - protecting subfloor from weather, prior to adding roof?

Hi,

How would I protect the subfloor from the elements prior to adding a roof?

I currently have a garage foundation that I would like to park my vehicle in, but I do not plan on finishing the first floor for a year or two. I'd like to put on the sill plate, beams, and subfloor now, and somehow protect the wood. Whatever I put down, it would either eventually become part of the house, or have to be removable.

Any ideas? builder's felt? plastic? Some type of paint?

Thanks!

I would not leave any type of sub-floor material exposed for a year or two. How about getting trusses and putting a roof on it, then when you are ready to do the first floor you can remove the shingles and plywood and re-use the trusses for the first floor roof.

Funny how you can double post and get the same answer from two different people. Check the Roof forum as well.

I'm hoping I'll get some advice other than "don't do it." It's not my first choice, but I can't afford to put up the building now. All I need is someone to think outside the box.

Soooo, what are some other options?

Do it. You don't want our advice, just corroboration on a failed project. And we won't give it.

Not true at all. If the answer was easy, or a standard building practice, I'd already know the answer. I'm just not willing to give up so quickly because you said so. Please don't take it personally; that's not my intention.

The subflooring that came with my log home kit is a product called Advantech. It has a 50-year warranty against water damage. Mine got rained on a number of times over 3 or 4 months until I was under roof, with no ill effects. I know Home Depot sells it.

When visiting the kit manufacturer's facilities in Tennessee last summer, I saw a foundation with Advantech that had been exposed for more than a year.

Excellent! They have a 300 day warranty on exposed wood as well. Plus, they have rimboard. This looks like the answer.

Thanks for the info!

Oh, I don't take anything personal, here. You are going to have leaks in the garage, unless you do a 4 layer elastomeric coating system to the Advantech (which is the only subflooring I use for the same reasons.....I just don't delay my finish time). You will run out of permit time in a year (in most cases). How do you plan on keeping your framing from rotting in two years? I wish you luck and a minimal amount of "do over".
