Drip Edge

What is Drip Edge?

Drip edge is a metal flashing that is installed at the edges of the roof to help control the flow of water away from the fascia and to protect the underlying roofing components. Drip edge overhangs the sides of the roof and has a small metal flange that is bent away from the fascia. It is non-corrosive and non-staining so that your roof looks good while being structurally stable.

Reasons To Use Drip Edge:

  1. Directs water away from the fascia and prevents water from rotting the fascia over time.
  2. Protects the edge of the decking due to water penetration during driving rains.
  3. Seals any gaps at the bottom of the roof where there is often a gap between the decking and the fascia, which could allow small animals to enter the attic.
  4. Helps protect the bottom of the roof line during ice dams that can occur during the winter months.
  5. Prevents movement between fascia and deck boards.
  6. Assists gutters to direct water away from your house and foundation.
  7. Extends the longevity of your roof and improves its overall effectiveness.

The Building Code That Requires Drip Edge

Building codes ensure that your home and roof are in compliance with your local municipality’s requirements to pass a home inspection. One of the most important codes has to do with drip edge.

An example of a building code is that drip edge shall be provided at eaves and gables of shingle roofs. This code means that drip edge must be installed on the edges of your roof.

Not only does it need to be installed on your roof to be in compliance with this code, but it has to be installed correctly to ensure your home’s safety.

Expanding on this code example is that adjacent pieces of drip edge shall be overlapped a minimum of 2 inches. Drip edge shall extend a minimum of a ¼ inch below roof decking and extend up a minimum of 2 inches. Underlayment must be installed over the drip edge along the eaves and under on the gables.
