I got a whole new roof done a while ago. I am just looking at pictures and I am really worried they did the roof membrane wrong. I've read that it should drape slightly between the rafters to allow water to run down to the gutter. However mine doesn't look like there's any drape, it looks rather taut!
Does anyone here know anything about what they're supposed to look like and tell me if mine is ok?!
I've attached a photo.
