Yes, extreme wind-driven rain can easily cause roof leaks by forcing rainwater horizontally or upward against standard building gravitational flow, pushing droplets past shingle overlaps, ridge caps, and flashing seams. Under normal downward rain conditions, overlapping shingles shed water effectively. However, high-velocity gale-force winds can lift shingle tabs or bypass underlayment barriers, driving moisture into vulnerable attic spaces. You can troubleshoot wind-driven leaks safely by inspecting attic rafters after severe storms. You can verify that your corrective action is successful when installing proper storm-rated underlayment, sealing shingle edges, and repairing loose flashing prevents interior water intrusion during subsequent high-wind weather events.
