question about underlayment?

Hi, I just had a garage built, and want to install the roof underlayment.

Once installed will it matter if it rains on this material?

Do i need to install the shingles right away?

Thanks for your help...

Either way it wont matter so long as you plan on installing shingles in the very near future. If using standard tar paper and it gets rained on, you will notice it wants to buckle/wrinkle which can be a PITA to deal with, so if your planning on shingling within a week, I would'nt even bother installing tar paper until that time.

Big miconception that rain will hurt roof sheeting, over a period it will-just as it would with wall sheeting, but many newly built homes are left sitting for a few weeks with exposed sheeting and deal with all the elements with no ill effects. Just get it shingled as soon as you can would be the only advise I'd give.
