Author raining on my new roof deck
J Geez

2006-06-26, 3:25 am

I'm building an addition and the roof decking was finished this past Friday
and due to a mixup the yard delivered me the wrong shingles. The correct
ones are being delivered Monday morning. Well I could not shingle the roof
this weeked like I wanted to, and now unexpectedly it's raining out right
now..pouring...and the decking is exposed. 5/8" plywood. There is now a
good chance of rain showers on and off for the next several days, and most
likely it will rain Monday for sure. How bad is it for my roof decking to
be getting wet unprotected? Can the underlayment and/or shingles be
installed in light rain or must the decking and underlayment be totally dry
to install? Should I just tarp the roof and wait for drier weather now?

Kind of dangerous to go up on wet decking, your roofers will probably
refuse until it's dry.

the plywood should be rated to be exposed to rain during the course of
construction, so it will be fine. if nothing underneath the .roof is
being harmed, then i wouldn't worry about it. wait for the rain to
quit.

I live in the Pacific North West. They build houses all year round
through rain or nothing would get done. The only time they don't do
roofing is during sleet and snow. I don't know where you are, but a
good roofer would continue to work, if you have an aversion to getting
up theitr while it is wet.

I agree but you will probably pay a bit more for roofing in the rain, right
?

I am relatively new at this and I shared your same concern a few months ago
when a subfloor was getting rained on. The rain didn't stop for 10 days and
the plywood subfloor was just fine when it dried out. So sleep well for a
bit. I have seen properties however, where the subfloor was left for months
in the rain and some warping took place at that point. They're still
building right over it so I am not sure that it is even a problem but put
the roof on as soon as the rain stops and you should be fine. If for some
reason, you can't then you might want to cover the roof with a simple tarp.
Huge ones sell for around $50 at Menards, Home Depot, Harbor Freight, etc.


P.S. I've got a flat OSB garage roof that is getting rained on right now.

If you put a nice tight roof on wet plywood sheathing, I wonder
if it will dry before it de-laminates. I wouldn't bet the farm on
it one way or the other.
