I am putting asphalt shingles on a porch roof. I got the roof covered
with #30 tar
paper, but now it is going to rain for a few days, so I'll have to wait
till things dry
out before proceeding. But I have noticed that the tar paper has
started to wave
and wrinkle somewhat after the rain. Will it still be ok to put
shingles over top
if it is wrinkled? Thks,
