How To Install Drip Edge On A Roof

Not everyone decides to install a drip edge, and not every roofer will recommend it. That being said, it could be worth it for your roof. But before we look more closely into why you might want a drip edge and what theyre good for, you might simply want to know what they actually are. So lets have a look:

Reasons To Use Drip Edge

Drip edge directs water away from the fascia and prevents water from rotting the fascia over time. Due to cohesion, surface tension, and other forces, water droplets tend to stick to one another and to the surfaces they are on, albeit slightly.

A drip edge is designed to take advantage of those forces and, along with gravity, direct water into the gutter.

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. However, without the drip edge, the water sticks to shingles, potentially working its way under the shingles to cause a leak.

For example, water may cling to the fascia, which may cause rot, or, in severe conditions, a leak into the home.

A drip edge prevents movement between fascia and deck boards, as well as assisting gutters to direct water away from your house and its foundation. Additionally, the drip edge extends the life of your roof and improves its overall effectiveness.

Drip edge protects the edge of the decking due to water penetration during driving rains. When conditions are serious, the wind pushes water around on a roof. Shingles, along with underlayments and ice and water protectors, keep wind-driven rain from harming the roofs deck.

Three Tips For Overlapping Drip Edge Flashing:

  • Overlap pieces at least a couple of inches shingle-style, with pieces higher up on the roof overlapping pieces lower down. This keeps the water on top of the flashing and away from the roof deck.
  • When lapping the eave metal, overlap them so the seam faces away from the direction of prevailing view. If the typical view is from right to left, place the left piece under the right piece.
  • Tip 2 is vetoed by prevailing winds for places with wind-blown rain issues.
  • To cut the lower rake piece in place, slide the lower piece downhill enough to make room to mark, cut, and bend. Mark the straight cuts with a speed square. Cut the initial square cut across the single-ply piece of the top. Next cut back square across the folded part of the top of the T. Cut the 45 degree bird’s mouth to allow the long end to be folded around the rake to the eave.

    TIP: Make sure to support the long end of the cut if you let it fall after cutting, it will bend down and kink the drip edge.

    Be sure to tuck the drip edge under the starter strip and felt paper. Slide the corner tight to the fascia. Make sure the corner is tight, and that the bottom edge is tight to the fascia before nailing off the drip edge. Place a nail at one end, then the other.

    You may need to nail through the starter strip into the drip edge. If you do, make sure the nails will not align with any shingle seams or cutouts above.

    Can Drip Edge Be Installed After Shingles

    The most popular time to install a drip edge is when new shingles are installed. However, the drip edge can be installed at any time. The materials involved include: a ladder, a flat pry bar, a hammer, tin snips, eave stripping, and galvanized roofing nails. Something else to consider is the drip edge eave strip, which is often made of galvanized metal. According to many roofers, a better alternative is a vinyl-coated aluminum eave strip. Thats because aluminum wont rust and it doesnt need to be painted.

    There are two existing approaches to the installation process:

    • Approach # 1 is about the installation of the holders to the rafters. The main thing is that fixing is carried out after the installation of lathing and before installing drip. Perhaps, this approach is the most reliable one.
    • Approach # 2 is about using holders made of plastic which are mounted on a fascia board such attachment method can not withstand avalanches of snow in the winter time, so it highly recommended to be used on roofs with a minimum angle of inclination only.

    Is Having A Drip Edge A Code Requirement

    Drip edges are required by the International Residential Code and since most U.S. states follow the same precedent set by the IRC, this means that drip edges are required for most types of buildings in the country.

    In fact, 49 states have adopted the IRC, so drip edges are generally required. Based on their benefits we touched on earlier, its clear that installing a drip edge is a good move on the part of homeowners.

    There are some instances in which a drip edge isnt required, however, such as in the case of historical buildings. If you have a prebent aluminum fascia that is flush with the decking of your roof, this basically serves the same purpose as a drip edge so you wont require one.

    However, its important to check with city hall in your area so that you can stay informed on the codes you need to consider for your home. You could also consult with a home inspector for advice.

    Shapes of drip edge vary, and the names can be confusing. As youll see below, some types are the same but go by different letters. Well outline the most common examples and why they might be the right choice for your shed project.

    Type C

    Also known as type L, this is one of the most common profile types for drip edge. It features an L-shaped profile. The side that sits against the fascia board has a small flange at the end to direct water away from the fascia and into the gutter.

    Type D

    Widely known as type T, this drip edge is identical to C-type, except that the top of the profile juts out, away from the roof. This allows water to fall further away from the fascia board and into the gutter. Many roofers use this type for eaves and type C for rake edges.

    Type F

    Type F is also known as gutter apron and is useful when replacing an existing drip edge or adding a drip edge to an existing roof structure. This profile is similar to type C, except that the fascia-facing part angles away from the structure.

    The angle provides extra clearance for moisture to reach the gutter. A good alternative when type D drip edge is too long for existing shingles on a shed roof.

    Where Should Drip Edges Be Placed

    The correct placement of a roof drip edge is on top of the roofs 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.

    Drip Edge Profile Type D

    Drip Edge Over or Under Felt?

    Despite it being called type D, this drip edge is in the shape of an uppercase T and has a lower flange that is at the bottom. It is also referred to as T style, drip metal, or D-metal. There is an association for asphalt roofing that prefers this profile because it keeps water even further away from the fascia.

    Despite that fact, Type C is still quite common and will be acceptable when it comes to most roofing and building codes and guidelines.

    Everything You Need To Know About Drip Edge

    When it comes to roofing, the importance of drip edges is often overlooked by homeowners. Though drip edges are a common feature on homes located in certain areas of the United States, they are not as common in areas that do not experience frequent or severe storms. In addition, drip-edges are sometimes excluded from a project in order to save money. While lacking a drip edge on your roof may save you money in the short-term, it can cause costly damage that will be expensive to fix. As a homeowner, it is important to fully understand how and why a drip edge is used. Here are some of the most common drip edge related questions and answers to be aware of as a homeowner.

    Whats The Purpose Of Roof Drip Edges

    Drip edges have two key purposes:

  • Direct water away from fascia: Due to cohesion, surface tension and other forces, water droplets tend to stick to one another and to the surfaces they are on, albeit slightly. A drip edge is designed to take advantage of those forces and, along with gravity, direct water into the gutter. 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. However, without the drip edge, the water sticks to shingles, potentially working its way under the shingles to cause a leak. For example, water may cling to the fascia, which may cause rot, or, in severe conditions, a leak into the home.
  • Protect from wind-driven rain: When conditions are serious, the wind pushes water around on a roof. Shingles, along with underlayments and ice and water protector, keep wind-driven rain from harming the roofs deck. However, on the edges, the drip edge must compete with the wind. Wind can easily push the water upwards before gravity pulls the water down. 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, winddriven rain could compromise the roof.

    Drip Edge Material Types

    Drip edges are made of various plastics and metals, which are both acceptable under most building codes so long as the metals are corrosion-resistant or galvanized.

    • Aluminum: A common material for drip edges, aluminum isnt as strong as steel. It doesnt corrode and is often sold in colors that match the rest of the home exactly.
    • Galvanized steel: Drip edges are designed to be in contact with water so, if they are made of steel, they need to be galvanized to prevent rust. Minimum 24-gauge steel is preferable so that the drip edge can withstand strong winds.
    • Copper: Copper is a sturdy metal that gives a roof a unique look. When used as a drip edge, it should be a minimum of 0.69 mm or 20 ounces.

    While plastic, vinyl and fiberglass drip edges may also be available in your area, these materials are best suited for use in nonroofing applications, such as above doors and windows.
