Asphalt shingles should overhang the exterior edge of the drip edge by ¼ to ¾-inch. Check local building code for drip edge requirements prior to the start of your roofing project.
How much should drip edge overlap?
Nail high up on the drip edge so that the shingles will cover the nails. Ideally, you’d nail about every 12 inches, and in no circumstances should you have 16 inches or more between nails. When you place the next drip edge piece, it should overlap the first by an inch.
What is the proper shingle overhang at eaves?
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.
Should drip edge be flush to 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.
How much should a shingle overhang drip edge Related Questions
Does drip edge go over or under roll roofing?
It is also a good idea to install drip edge flashing before laying the rolled roof. Drip edge is a type of metal flashing that is installed at the edges of your roof to keep water from getting underneath your roofing materials.
What is the proper placement of drip edge?
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.
Does drip edge go on all sides of a 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.
How far below drip edge should gutters be installed?
How Far Should Gutters Be From the Roof Edge? 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 shingles overhang the roof?
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.
What is the difference between drip edge and rake edge?
The drip edge on the lower portion of the gutter apron helps to direct water into the gutter instead of running behind it down the fascia board. Rake edge flashings work in a similar manner as gutter apron but protect the rake frieze boards instead of the fascia boards.
Does roofing paper go on before drip edge?
Installing roof drip edge flashing properly 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 gutters go over or 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.
Does drip edge go on eaves?
A drip edge should be installed on the eaves and rakes of the roof, flush with the decking and fascia. On eaves, the drip edge is installed directly to the deck with underlayment installed over it for proper water shedding. On rakes, the underlayment is installed over the drip edge.
Is drip edge installed over tar paper?
It protects the edges of the plywood and prevents water from seeping underneath the soffits, or underside of the overhanging roof, and staining or damaging the siding. The drip edge goes under the tar paper and the roof covering.
What happens if you don’t put a drip edge on a roof?
If your roof doesn’t have drip edge, water gets behind your gutters and rots out both your fascia board and roof decking. When getting a roof replacement, your drip edge must be replaced. Be aware, some roofing contractors leave it off your estimate to lower their prices to beat out the competition.
Does drip edge go under shingles?
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.
Does starter strip overhang drip edge?
Whether installed at the eave or the rake, the starter shingles should overhang the edge of the roof by ¼ inch to ¾ inch. Typically, the finish shingles are then installed to align with the edge of the starters.
Do shingles go over or under flashing?
Flashing should overlap the roof-covering material, but on asphalt shingle roofs, for aesthetic reasons, the part of the headwall flashing that extends down over asphalt shingles is often covered with a course of shingle tabs.
How much overhang do I need for a metal roof with a drip edge?
Once the drip edge is installed, the shingles should extend ½ inch to ¾ inch past the drip edge. If the shingles are allowed to extend too far, then they can be caught by the wind and damaged.
How far should a roof overhang a gutter?
This overhang is necessary to prevent water from rolling around the edge and turning back across the bottom of the metal due to surface tension. But on roofs with a gutter, a shorter 1.25 to 1.5 inches is recommended.
