We recently completed a roof replacement on a home built in 1997, removing the original roofing system that had reached the end of its lifespan. After nearly three decades of exposure to Western New York weather, it was time for a full tear-off and upgrade.
During the tear-off process, we identified a major design issue: a dead valley, where two roof facets pushed directly into each other. Dead valleys are prone to holding water and snow, making them one of the most common sources of long-term leaks.
Correcting the Dead Valley
Instead of reinstalling the same problematic design, we reframed and installed a W valley system. A W valley uses metal flashing formed in a “W” shape that directs water away from the center seam, preventing pooling and dramatically reducing the risk of leaks.
This upgrade significantly improves drainage and long-term roof performance.
Our Installation Process
✔ Full Tear-Off of Original 1997 Roof
We removed the original shingles down to the decking to ensure a clean, proper installation.
✔ Ice & Water Shield Protection
Ice and water shield was installed in key areas, including valleys and eaves, to protect against water intrusion.
✔ Premium Synthetic Underlayment
We applied high-performance synthetic underlayment for added durability and moisture resistance.
✔ Black Sable Architectural Shingles
The homeowner selected Black Sable architectural shingles, giving the home a rich, dimensional look while providing excellent wind resistance and long-term protection.
✔ Matching Ridge Vent System
To complete the project, we installed a ridge vent system with matching cap shingles to ensure proper attic ventilation and a clean, finished appearance.
The Final Result
By correcting the dead valley and installing a proper W valley system, this homeowner now has a roof designed for efficient drainage and long-term durability. Combined with the Black Sable shingles and upgraded ventilation, the home is protected and visually refreshed for decades to come.
