Restoring Critical Drainage Valleys on Tile Roofs
Where two sloped roof sections meet, the valley trough channels hundreds of gallons of rushing rainwater per minute during intense monsoon downpours. In Mesa, fine airborne caliche dust settles into the hidden space between the valley metal and the cut tile edges.
Over successive storm seasons, this silt forms hardened dams, blocking natural flow. Water backs up sideways across the metal flashing flanges, flowing over the edges directly into attic spaces. Dispatched contractors disassemble valley tile courses, pressure-wash metal troughs, and install widened W-profile valley iron with peel-and-stick membrane liners.
Key Service Advantages Dispatched Roofers Provide:
- Caliche Dust Silt Dam Removal
- Heavy-Gauge W-Valley Metal Upgrades
- Secondary Ice & Water Shield Membranes
- Clean Diamond-Blade Tile Angle Cuts
Closed Valley vs. Open Valley Systems
Proper valley design is critical to avoid debris dams in the desert environment.
- Closed Cut Valleys: Cut tiles meet tightly over metal; prone to silt buildup in dusty Mesa climates.
- Open Ribbed Valleys: 4-6 inch open center channel allows rapid discharge of hail, sand, and leaves.
- Best Practice: Dispatched roofers widen valley openings to prevent water damming.

Yes. Technicians remove only the 2 to 3 courses of angled cut tiles on either side of the valley, install new heavy-duty metal and self-adhering membranes, and neatly re-seat the tiles at a fraction of full roof cost.
