Your roof is your building's first line of defense against the elements. Understanding how it works helps you protect your investment.

Pro Tip #181: Roof Pitch and Panel Overlap

The minimum panel overlap for metal roofing increases as pitch decreases. At 3:12 pitch, a 6-inch overlap is standard. At 1:12 pitch, you need 12 inches or more. Insufficient overlap at low pitches allows wind-driven rain to enter at the laps.

This tip comes directly from real-world experience working with customers across Tennessee, Arkansas, Mississippi, and Kentucky. The issues that cause the most problems are almost always the ones that could have been avoided with a little advance planning.
