The drip edge should be installed on top of the underlayment at all rakes, and below or on top of the underlayment at the eaves. At the eaves, when installing the drip edge on top the underlayment, a 4-inch wide layer of asphalt roof cement (complying with the ASTM D4586, Type I or Type II) is required.
Does drip edge go on before ice and water shield?
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.
Does drip edge go over or under the felt?
1 Answer. It depends on where the drip edge is. At the side, or gabels, of a roof, the drip edge goes over the roofing felt. At the bottom of the roof, the drip edge goes under the roofing felt.
Can you install drip edge after shingles?
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.
How far should shingles hang over 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.
Does drip edge go on before fascia?
The correct placement of a roof drip edge is on top of the roof’s exterior cover directly between the sheathing and the fascia board, which forms a drainage gap between the drip edge and the fascia board. As a result, the drainage improves water flow and protects the roof from potential water damage.
How far below the drip edge should the gutter be?
A safe distance between the gutter and the roof edge should be between 2 to 3 inches. If the gutter distance is more than 3 inches, the rain will run off the roof and won’t drain properly.
Does drip edge go on all sides?
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.
Where do you put ice and water shield?
Where Is Ice & Water Shield Needed? On the eaves of your home up to 24″ inside the exterior wall (this usually means at least 2 rows or 6 feet) In every valley (1 row or 3 feet) Around every pipe before the flashing is installed. Along every wall, chimney, or skylight where flashing will be installed.
How far should shingles overhang the rake?
The edge of the shingles should hang over a roof between an inch and an inch and a half — or between a half inch and three-quarters of an inch if drip edge flashing is installed. Too much overhang and the shingles could blow off in high winds; too little can allow water to seep into rake or fascia boards.
Does drip edge go on rakes and eaves?
It’s important to understand that drip edge installation is different for eaves and rakes. After your roof deck has been prepared, and before you install underlayment, you need to install drip edges at the eaves. You install drip edges on the rakes after you install the underlayment.
How far should drip edge be from fascia?
Drip edge height: 1 5/8″ Drip edge lip extension: 1/2″ Recommended drainage gap: 1/4″ (approx) spaced off of the fascia board.
How do you attach drip edge to an existing roof?
Make sure the outer edge extends over the gutter. If it doesn’t, pull the drip edge out slightly from under the shingles. Secure the drip edge with roofing cement. Apply a continuous bead of cement along the top of the drip edge, then press down on the shingle.
Should shingles overhang gutters?
Most shingle manufacturers recommend a 1/4 to 3/8 inch overhang over your eave, which is where your roof ends by your gutter. In many cases, and particularly as the home ages and settles, the roof edge at the eave edge can wave in and out by more than this amount.
Does fascia go on before shingles?
Fascia and soffit are installed after the roof installation is finished. It is ideal that soffit and fascia materials be installed before you place tiles or any other type of roofing material on the roof.
Should you use drip edge touch fascia?
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.
Do you nail drip edge to fascia?
You don’t. The drip edge is attached onto the plywood roof decking before any shingles are installed. And assuming that the roof’s bottom edge has a typical fascia trim, that trim should be in place before the drip edge.
What is the difference between drip edge and gutter apron?
The most obvious attribute that distinguishes a gutter apron from a drip edge is the fact that a gutter apron is more of an L-shaped metal rather than a T. A gutter apron also comes in metal strips with aluminum and steel sheets. Like drip edge, a gutter apron may be available in many different colors.
