Hi - I have a roof that was installed less than four years ago that is now leaking. Roofer seems to be cooperating and saying they will repair but he is unable to tell the issue. I am curious if based on the pitch of the roof if the shingles were laid correctly and hoping the forum's expertise can confirm. Center Roof image shows wide shot of roof pitch. Right detail shows the area of the roof that is leaking. Shingle detail shows how the shingles are overlapping. Thanks for the help with my Money Pit! *Bonus question - the ridge vents were simply installed over the gap cut in ridge board. I have a lot of debris in the attic that seems to come in from the ridge vents. Is this normal? Do not think water is coming in from this from what I can see.
