What happens here

The video begins by demonstrating a common issue with drip edge and starter shingle installation. Water is sprayed onto a mock-up of a roof edge. With the drip edge 'ran tight' (meaning possibly not extended far enough or with a starter shingle placed too close or on top), the water flows from the roof, around the drip edge, and wicks back down the fascia board, potentially reaching the wall.

Goal: Show how water wicks back with improper drip edge and starter shingle placement.

Tools and materials

  • Garden Hose — Simulating rain to demonstrate water flow
  • Roof Edge Mock-up
  • Water N/A — Simulating rain

What they say

Hide

When your drip edge is ran tight, the water goes from here, down, around, and goes down your fascia, and even can run back all the way to your wall. If we pull out our starter and shingle, this water stays away from the drip edge and doesn't even have a chance to make it back. As you see here, we stay dry all the way through. It's best to pull both out, but even in this case, it still doesn't really make it back to the drip edge. While your drip edge is supposed to be gapped, we all know it doesn't always
