Hi
In 2022 I moved into my house and the garage roof had a leak. That winter 22/23 i had the leaking side repaired. It continued to leak so winter 23/24 i had the others side done (pitched roof) the middle leaks most.
During really heavy prolonged driving rain it leaks still. I've lifted the flashing and the guys laid the felt different on each side. Is one correct and one possibly causing the leak?
