A speed valley is an informal roofing term often used for a faster closed-valley shingle method. Because the term can vary by crew or region, it should be clarified.
Why It Matters
Valley shortcuts can create long-term problems if they conflict with manufacturer instructions or do not manage water properly.
Common Problems
Common issues include unclear terminology, poor shingle cuts, fasteners placed too close to the water path, and valley styles chosen for speed instead of performance.
Building Codes & Industry Standards
Valley installation should follow the shingle manufacturer’s approved methods, applicable underlayment requirements, and local code.
Exterior Echelon Notes
Exterior Echelon avoids vague valley language with homeowners. The goal is to explain the actual valley method being installed and why it is appropriate.
