Water running behind your gutters?

Gutter Flashing & Drip Edge

Rain dripping between the gutter and the house means roof water is missing the gutter. Flashing closes that gap.

What you'll notice

Signs Water Is Getting Behind the Gutter

  • Drips between the gutter and the wall when it rains
  • Dark streaks or peeling paint on the fascia
  • Stains on the soffit or the top of the siding
  • Gutters that stay nearly dry in steady rain
  • Soft wood where the gutter is fastened

Water coming over the front of the gutter is a different problem: see gutter repair.

How it's meant to work

How Roof Water Should Enter the Gutter

At the roof edge, water has to break away cleanly and drop into the gutter. That takes two things: an edge that sheds water outward, and a gutter whose back sits behind and below that drip line.

If either is off, water clings to the underside of the shingles and follows the wood toward the house.

Where it usually goes wrong

No metal at the roof edge
Common on older roofs.
Metal that stops short
It ends behind the gutter instead of over it.
A gap behind the gutter
The gutter was hung low or has pulled away.
Short shingle overhang
Water runs straight down the face of the board.

Sorting out the names

Drip Edge, Gutter Apron and Gutter Flashing

The names get used interchangeably, but they aren't always the same piece of metal.

TermWhat it usually meansWhat it does
Drip edgeMetal along the roof edge, under the shingles. Normally part of the roof.Sheds water off the edge of the roof deck.
Gutter apronFlashing with a longer leg that tucks under the shingles and hangs into the gutter.Carries water over the back of the gutter.
Gutter flashingA general term for metal bridging the roof edge and the gutter.Closes the gap behind the gutter.

Trades use these names differently, and the right piece depends on how your roof edge is built. We'll tell you which one yours needs.

Timing

When Flashing Gets Added

With new gutters

The roof edge is easiest to flash with no gutter in the way. See seamless gutter installation.

During a replacement

Stains on the fascia show where water got behind. See gutter replacement.

After fascia work

If water rotted the old board, the cause gets fixed too. See fascia board replacement.

Flashing can also be added to sound existing gutters.

How We Evaluate Your Roof Edge

  1. Look for the evidence

    Streaks, peeling paint and soft spots.

  2. Check the roof edge

    Is there metal under the shingles, and where does it end?

  3. Check the gutter

    Its height and how tight it sits to the fascia.

  4. Check the wood

    Soft fascia gets replaced before anything is fastened to it.

  5. Tell you what it needs

    Flashing, a gutter adjustment or new fascia, each priced separately.

Damaged shingles or roof decking is work for a roofer, and we'll say so.

Gutter Flashing and Drip Edge Questions

My roof already has drip edge. Why is water still getting behind the gutter?

Usually the drip edge ends behind the back of the gutter, or the gutter sits too low or has pulled away. Either leaves a gap.

Do the gutters have to come down to add flashing?

It depends on how the gutter is hung and how much room there is at the roof edge. We check at the estimate and tell you before any work starts.

Does every gutter installation need flashing?

No. If the roof edge already delivers water into the gutter, there's nothing to add.

We'll look at the roof edge, the gutter and the fascia, and tell you which one is letting water through.
