Rainwater is getting behind the drip edge on a new roof because the shingles are cut too short, less than a quarter inch beyond the roof edge, causing water intrusion under the drip edge in that area.

Existing drip edges are not preventing water intrusion because shingle overhang is too short, likely due to improper installation; no specific software solution mentioned for this anomaly detection.
