See this is what I mean about not knowing anything.
I don't know nothing about roof systems and shingles. They mean nothing to me.
I thought, you cut your felt to size, you nail it down, that's it.
I don't wanna sound like I'm being rude or anything. But is that basically it, would I need to seal it anywhere, would I have to seal over the nails, do I use certain type if nail.
Thanks for the replies and help all the same.
