The drip edge needs to hang significantly off the edge of the roof and has two to four inches of lower flange to combat this. And, of course, without any drip edge at all, wind‐driven rain could compromise the roof.

How big does a drip edge need to be?

Metal Edge Drip: A drip edge has to be resistant to possible corrosion and should be 36 gauge or larger. Before you start the installation, remove all dirt and debris from the roof and take the measurements of the exterior edges to determine how much drip edge is required for the project.


How far below the drip edge should the gutter be?

The gutter should be installed as close to the shingles as possible; no more than 2 or 3 inches. If the gutter distance is more than 3 inches, the rain will run off the roof and won't drain properly.

Do you nail or staple drip edge?

The drip edge should be nailed high on the shingles. That is done so that the shingles cover the nails. About every twelve inches or foot, a nail should be hammered in. For the next drip edge piece, it should overlap the first by an inch.

Should I caulk under drip edge?

Another place that should never be caulked is the space between the siding and the flashing above a window; this piece of flashing is often referred to as drip flashing, drip cap, or head flashing. Caulking this opening shut is a very common defect, even on new construction.

Should there be a gap between fascia and drip edge?

A metal drip edge will help protect the sheathing under the roof, but if it's installed too closely to the fascia board, it can still cause water to be drawn into the fascia. The best installation method is to leave a gap between the drip edge and the fascia board, about the width of a finger.

Ice and water protector needs to be installed directly onto the roof deck after you have placed the drip edge at the eave. (The drip edge will be installed over the ice and water protector and other underlayments at roof rake edges.)

Does drip edge go on all sides of roof?

Drip edge is installed around the whole perimeter of the roof. It is used to hold the underlayments down and create a watertight seal around the edge of the roof. Only the face of the metal is seen and is usually just white one to one and half inch stripe located right under the shingles and above the fascia.


Should shingles be flush with drip edge?

Shingles should be installed over the drip edge a minimum of 3/8” (9 mm) at both the eave edge and the rake edge. If the drip edge extends… out from the rakes and eaves (typically called DL Style or D Type), the shingles may be installed flush with the drip edge.

How close should drip line be to plant?

A good rule of thumb is to place a drip emitter evenly spaced along the plant line and a minimum of six inches from the base of the plant.

How long should a drip line be?

This tubing is an essential component in a drip system, but too much of it becomes a maintenance headache. Limit the use of ¼ tubing to no more than 12 inches in length per run. LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length.


Can water get under drip edge?

With the code-recommended installation of the ice barrier over the drip edge, water can back up at the eaves edge and get behind the vertical leg of the drip edge, where it can end up flowing into the joint between the fascia and the roof sheathing.

Can drip edge be installed later?

The drip edge is often replaced when new shingles are installed, but it can be replaced at any time. Asphalt roof shingles can become brittle in cold weather, so wait until a warm (but not hot) day to remove and replace eave stripping.

Do you put tar paper down before drip edge?

If the drip edge is along the eaves of the roof, it goes underneath the felt underlayment. When the drip edge is along the rake edges, it is placed over the felt paper underlayment.

Do you tuck gutters under drip edge?

It is recommended that gutters are placed under or 'behind' the drip edge of your roof. A drip edge refers to a component that hangs over the roof and has an outward projecting lower edge.

Should gutters be flush with roof?

Your gutters should extend beyond your roof shingles, not align with them. Water naturally runs across shingles, down the shingle edge, and even underneath it. When gutter sections are installed directly in line with your roof shingles, the shingles impair the natural flow of water.


What goes under the drip edge?

The best way is to install the roof drip edge only along the eaves first, then place ice-and-water barrier (in the snowbelt) or felt paper (underlayment) over the drip edge. This lets any water that gets on the roof run down the underlayment and over the drip edge.

Do gutter guards go over drip edge?

No matter what kind of gutter guard you choose, it must be properly positioned under the roofing materials. If you have drip edge (metal flashing that's installed at the edges of the roof), gutter screens clamp onto the front of the gutter, go underneath the entire roof, and sit on the drip edge.

Where do you nail drip edge?

To install a drip edge on a newly constructed roof or on a re-roofing job, attach the drip edge along the roof's eaves first. The roof leg should extend a minimum of 2” back onto the roof sheathing. While the vertical leg should be placed 1/4” – 1/2” away from the fascia.
