Is tar paper allowed to go under or over the drip edge?
The drip edge should be placed over the paper at both the eaves and under the rake. It's a trap! In my early days of construction, I learned that the tar paper should be placed OVER the drip edge so moisture does not seep under the drip edge.
Similar questions are asked: What goes first, tar paper, or drip edge?
It is best to place the roof drip edge along the eaves, then add ice-and water barrier (in the snowbelt or felt paper) to the drip edge. This allows any water to run off the roof and down the underlayment, then over the drip edge.
The next question is: Which side of tarpaper goes down? Lay the sticky side down when laying tar paper sheets. The and sides of tar paper are clearly different. Although one side can be sticky, don't expect it leave any glue-like residue. The other side is smooth and paper-like and often contains line markings and lettering.
Moreover, does drip edge go over or under felt?
1 Answer. It all depends on where the drop edge is. The drip edge is located at the gabels of a roof and goes above the roofing felt. The drip edge runs under the roofing felt at the bottom.
Is tar paper allowed to be used over water and ice shields?
Water shield is different than felt paper. It's a rubberized membrane which sticks to the roof sheathing and itself. If installed correctly, it creates a waterproof barrier that can stand water. Felt paper doesn't stick to anything.

Do I need drip edge with gutters?
If the home has no gutter, the drip edge will prevent the water from running down the fascia and onto or into the soffit cavity. Shingles, along with underlayments and ice and water protector, keep wind-driven rain from harming the roof's deck. However, on the edges, the drip edge must compete with the wind.
Why does water leak behind my gutters?
If the gutters are clogged, it's possible that the water is overflowing the gutters and this is contributing to the leak. Water should run out the downspout and away from the house without filling the gutter. If the water fills the inside of the gutter, this means the gutters are clogged.
How far should shingles overhang drip edge?
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.
How do you install drip edge on a shed roof?
How to Install Drip Edge on Shed Roof
- Install eave drip edge by nailing it to the sheathing.
- Extend drip edge an inch at each end.
- Install roofing felt.
- Install rake drip edge over the felt.
- Nail every 12” or less. Make sure rake edge overlaps.
- Rake drip edge overlaps the eave drip edge.
- Bend eave drip edge corners under rake edge.
Can you install drip edge on existing roof?
Replacing Drip Edge Eave Strips:
Install the eave strips on the lower roof edges first, with the eave strips under the shingles and felt underlayment. Align one end of the lower eave strip even with the edge of the roof decking. Lift up roof shingles, and nail the eave strip in place with galvanized roofing nails.Is a drip edge necessary on a metal roof?
A drip edge is a metal (usually aluminum) strip which extends beyond other parts of a roof and directs rainwater off the roof away from the fascia and into the gutter. This is important because a badly positioned drip edge—or no drip edge at all– can cause overflowing of gutters, over front or back.
Can drip edge be installed after gutters?
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.
How much should roofing felt overlap?
Roofing felt is required to overlap 2 inches over the lower felt course. The overlapping felt creates a secondary barrier for moisture and wicks water away from the shingles above and the sheathing below. Therefore, a 2-inch overlap provides redundancy at the edges where the barrier is weakest.
Should shingles extend past drip edge?
Yes. Shingles should not extend more than 3/4” (19 mm) past the drip edge. If shingles overhang the edge of the roof by more than 3/4” (19 mm), then they are not supported and may crack and break off. In addition, the wind resistance at the roof edge may be compromised.
Is felt paper waterproof?
Tar paper is a heavy-duty paper used in construction. Tar paper is made by impregnating paper or fiberglass mat with tar, producing a waterproof material useful for roof construction. Tar paper has been in use for centuries.
Should tar paper be used under shingles?
Answer: Roofing felt is a layer of tar paper installed beneath the shingles to provide a backup waterproof membrane in case of leakage. Felt, otherwise known as underpayment, is required when asphalt shingles are installed as a first layer of roofing or when they are applied over wood shingles or a built-up roof.
What is the purpose of drip edge?
Drip edge is a metal flashing that is installed at the edges of the roof to help control the flow of water away from the fascia and to protect the underlying roofing components. Drip edge overhangs the sides of the roof and has a small metal flange that is bent away from the fascia.
What is the best roof underlayment?
Synthetic underlayment (technically non-bitumen synthetic underlayment) is the preferred underlayment of most roofing professionals today. Synthetic underlayment basemat is saturated in asphalt. The addition of fiberglass gives synthetic products superior tear resistance and stability.
Does felt go under ice and water shield?
Re: Felt Paper And Ice/water Shield
I always install the felt above the ice and water barrier. It is a common look out for the next time the roof needs to be worked on.Do roofers replace fascia?
Soffit, Fascia, Gutter, and Eaves Replace & Repair Estimator
Most often, you'll want to replace your fascia when you replace or repair gutters. Most licensed contractors can typically repair or install all three. Contractors will typically charge by the project, ranging anywhere from a $600-$6,000.Which is better Tyvek or tar paper?
In general, non-perforated housewraps (Tyvek, Amowrap, and R-Wrap) are considerably more permeable to water vapor, ranging from 48 to 60 perms, than perforated housewraps. All sheathing wraps, including asphalt felt paper, will effectively shed water on vertical surfaces.
How long can tar paper be exposed?
Supposedly, synthetic felt can be left exposed for something like 90 days and is more tear resistant than paper felt. It is lighter and comes in larger widths, too, so it is easier to handle.
