It's supposed to rain tonight and my new roof isn't fully installed

[purbeast0]

This is the first new roof I've ever had and with all of the rain we've had in the DMV area it was pushed back nearly a month. They started this morning and couldn't finish everything. I talked to the guy who is leading the installation and he said that they put down the stuff that goes under the shingles (forget what its called) and he said it will protect the wood underneath from getting wet if it rains.

As someone who's never done this before, it was a bit concerning but he said it should be okay. I know I've seen other roofs covered with tarps but I don't know the state of the roof under it in those cases.

This company came recommended and has good Angie's List rankings and was the company I had the best vibe from when getting estimates. So I do trust the guy but figured I'd ask on here. It's not supposed to pour all night but it looks like there is an hour or so that has rain in the forecast this evening. And tomorrow they are going to finish it all up and put the shingles on.

is it white or black? black and paper like is tar paper, not many roofers use it anymore. white or other colors is they synthetic underlayment and that stuff should be fine for a little rain. if its black and rubbery then its ice and water shield witch will also be fine.

It's black and looks rubbery and I know that they were installing ice shield as that wasn't on there at the previous roof installation but now it's part of code so it's required. So I will go on and guess that is what it is because he told me it would be fine and I just don't remember exactly what he called it.

I can't make out what it says on the stuff now because it's too dark. I googled ice and water shield and see this Grace brand keep popping up and it's not that. I see the word GUARD on the stuff pretty large but that's all I could make out just because it's too dark.

Tar paper won't be branded. So you should be fine.

Even though the forecast said 100% rain last night, we got nothing.

Your roof was "dried in" meaning it was water proof. As a rule roofers don't leave a roof open to the weather if there is any chance of rain. It makes their insurance premiums skyrocket.

My roofer wouldn't start until he had 4 clear days. He just doesn't like climbing the roof that is slick but also to keep any leaks forming.

VERY unlikely this would cause any problem. That "tar paper" first layer does make the roof waterproof. It just is not really tough to stand up to harsh weather for many years. So an normal single storm is not a problem. I expect the roofers will wait a little if necessary (may not be needed) to ensure that layer is dry again before installing the shingles over top of it. The overlapping shingles are what makes a really durable weather-resistant and waterproof layer. After it's all done, that "tar paper" layer is a sort of backup for minor shingle defects and leaks.

Glad it didn't rain on your project. It doesn't take much moisture on the top side of drywall to cause a ceiling problems....water tends to pool up then run to the lowest point. I kind of wish I lived in the desert sometimes.....rain can really suck.
