Technical Guide
What Katy Property Owners Need to Know
Roof valleys channel hundreds of gallons of rainwater every minute during torrential downpours. When valley underlayment deteriorates, or when debris accumulation dams runoff water, water forces its way laterally beneath adjacent shingle cuts, creating destructive leaks along interior wall seams.
Common Failure Triggers
Primary Causes of Roof Valley Leak Repair in Katy
Understanding what causes this component to fail in our local subtropical climate:
Corroded Valley Flashing
Galvanized metal valleys rust through along lower seams after years of standing moisture and granule abrasion.
Improper Valley Shingle Fastening
Nails driven within 6 inches of the valley centerline puncture underlayment membranes in direct water flow paths.
Closed Valley Shingle Cracking
Woven architectural shingles flex and fracture along the sharp valley bend under extreme heat and foot traffic.
