The valleys on your roof — where two slopes meet — are some of the most vulnerable areas for leaks. Water, snow, and debris naturally channel into valleys, making them a common source of damage if not properly protected.
At Three24 Standard, we install valley flashing protection with premium Ice & Water Shield underlayment. Unlike standard felt, Ice & Water Shield is a self-adhering, waterproof membrane that seals directly to the decking, creating a watertight barrier under your shingles. This ensures long-term protection against leaks, even in severe weather.
Service Includes (Per Roll):
Removal of existing valley material (if applicable)
Installation of Ice & Water Shield membrane in valleys
Proper shingle overlap for maximum water-shedding
All nails, fasteners, and professional labor
Clean, protected job site during installation
Why It Matters:
Roof valleys are the #1 source of leaks in residential roofs
Ice & Water Shield provides superior waterproofing compared to standard felt
Meets or exceeds code requirements in most areas
Extends roof life and protects your home’s structure
