I have a leak where my porch roof attaches to the side of the house. I’ve seen it drip twice, both times in a storm when the wind is blowing hard (normal rains there seems to be no drip coming through). I have not been up on the roof yet to check, by my guess is that the guy who flipped the house did a terrible job on flashing (or didn’t install it at all) when he put a new roof on the house. House has vinyl siding.
Question: Can I install flashing or some type of protective barrier without tearing the shingles off the roof, and starting over? If so, how?
Thanks for any and all advice!
