Complete Roof Replacement & Substrate Repair for Ms. May in College Area
A complete tear-off, dry rot shear wood replacement, cool roof underlayment, and architectural shingle installation that resolved active water intrusion.
1. Homeowner's Starting Problem
Ms. May’s College Area home suffered from aging 20-year-old asphalt shingles, persistent roof leaks along chimney flashings, and sagging fascia boards along the northern eaves.
2. Field Inspection Findings
Upon tearing off the old single layer of shingles, the crew identified 180 square feet of dry-rotted plywood sheathing near the valley and compromised drip edges that permitted water migration into rafter tails during winter rains.
Work Performed & Construction Details
- Full tear-off and disposal of existing failed roofing materials.
- Removed damaged plywood deck and replaced with 1/2-inch CDX exterior plywood sheathing.
- Installed high-temp self-adhering ice & water shield at valleys, sidewalls, and chimney base.
