Jason, a homeowner in Texas, asked:
I am in the middle of a remodel and addition. We are basically adding a rectangular building to the back of the existing house to form a "T" shape. The shingles were just installed on the addition and tied into the existing shingles. There is a bulge at the seam where the new shingles meet the old shingles. The roofer is telling us that this is standard. Is that true?
Hello Jason. Thanks for reaching out to us. It’s always tough when you’re tying a new roof into an existing roof. The bulge could be they didn’t remove the existing shingles and laid the new shingles on top of it and tied in. It could be the new shingles are thinner than the old shingles and it doesn’t lay smooth or they come together. Do you have any pictures?

Yes, it seems to be accurate. When opting for a closed valley installation, you'll have multiple courses on one side. If the customer has any significant concerns, they can consider hiring a home inspector to ensure the installation is done correctly. I hope this information is helpful.
