How To Install Gutter Flashing

Should there be flashing behind gutters?

Why Flashing is So Important. Flashing creates a seal between your gutters and your roof line, which allows water to flow off your roof and into the gutter. Without it, some water would also flow behind the gutter, which would damage the building surfaces beneath the roof.

Do roofers install flashing?

Roof flashing is a thin material, usually galvanized steel, that professional roofers use to direct water away from critical areas of the roof, wherever the roof plane meets a vertical surface like a wall or a dormer. Flashing is installed to surround roof features, such as vents, chimneys and skylights.

How do I stop rain from running behind my gutters?

How Do I Solve the Problem? If your gutter has been previously installed, rather than taking it down and redoing it, you can easily place a small strip of metal flashing under the drip edge and over the back of the gutter (as shown by the illustration at the bottom of this page) so the water will shed into the gutter.

What is flashing between fascia and gutter?

Gutter flashing provides a waterproofing tool that diverts water from the roof’s fascia and into the gutter itself. It provides increased gutter efficiency. A thin, rectangular strip with a bend of a 35-degree angle, this type of flashing diverts water that falls from the drip edge into the gutter.

Is gutter flashing the same as drip edge?

As the water drops on your metal flashing, there’s no way they can directly be reverted into the gutter– unless you have a pump. In contrast, having a drip edge will help you direct the rainfall straight into the gutter instead.
