I was climbing off the roof over our car port and got a look at the roof over the addition we put on two years ago. I noticed along the edge that extends beyond the wall of the house that the tiles are cut even with that gable end and I can see underneath them. Meaning, the underlayment is exposed there. I guess I expected to see some sort of flashing or something that would block water intrusion. Anybody know if that’s a proper installation or do I need to correct?
