Just had my roof redone with 2 layers of underlayment and you can see under the tiles the underlayment is not lay flat in several spots. I’m concerned in a hard windy rain that water will go right underneath the paper. Also, originally the roofer mentioned a flashing that goes underneath these tiles so birds and rodents can’t get in there. It’s being done on all new roofs. They did not install that. Thoughts?
