Did you know drip edges can be crucial for your roofing system? If you weren't aware, think about this: water tends to accumulate on your roof when it rains. Without a device directing the water away from the roof, damage to the fascia and shingles may begin.
We're talking about water damage, wood rot, and other issues that could affect the livelihood of your home. To put it into perspective, when mold is given the chance to run rampant, more than just your roof will be at risk. Besides the lifespan of your roof decreasing, other parts of the home may fall victim to deterioration and health risks. Not to mention, mold is unsightly, persistent, and will attract rodents.
That doesn't sound fun, does it? Luckily, drip edges come in handy to help counteract these problems.
Here at RoofCrafters, we've repaired homes that lack proper drip edge flashing for almost thirty years, and we've seen mold and wood rot that not only affects the roof but the structural integrity of the entire home. If you're curious to know about the significance of this once-overlooked roof protection component, you've come to the right place. This article discusses the what, why, and how of drip edge flashing to give you an idea of why it's vital for your roofing system. By the time you're finished reading, you'll have expert-level knowledge of this roofing material.
What Is Drip Edge?
Drip edges are a type of metal flashing installed on the roof's edge. They're often made of materials consistent with your specific metal roof; some are even constructed of vinyl, fiberglass, or durable plastic.
Known by a few different names, drip edging can be a vital component of many roofing systems. This is because its primary function is directing water away from the fascia and into the home's gutter. We know wood rot and leaks sound like a terrible time, but the other bad news is that additional issues can occur in homes that don't have drip edges installed on them.
Why Is Drip Edge Flashing Important?
If you aren't a fan of having insects and critters crawling around your home, drip edging can help prevent them from coming in. Drip edge flashing acts as a seal to the space between the decking and fascia, making it hard for bugs and other pests to squeeze into the home. Some common animals that can make their way into homes are squirrels, rodents, and even bats.
Another reason to consider drip edging is to help keep your porch dry. During a downpour, rain can wash down from your roof and onto the porch if there isn't anything redirecting it into the gutters. Speaking of dry, if you have a basement, pay close attention to the next perk of having a drip edge installed.
This roofing material helps protect your basement. When drip edges redirect water off the roof, they also turn it away from the ground directly beneath it. This is where the basement can be found in a lot of homes. Having a drip edge to intervene can ensure that water doesn't soak through the ground and into your basement during heavy rain.
Protecting Your Home from Rain: The Role of Drip Edge Flashing
Drip edge flashing is important for protecting your home from rain damage, especially in heavy rain areas. Keeping your roof in good condition and preventing moisture problems is vital.
When rainwater flows off your roof, it can seep between the roofing material and fascia boards. Over time, this can lead to the deterioration of these boards, and even affect the rafters along the edge of your roof. Drip edge flashing acts as a barrier, directing rainwater away from these vulnerable areas and into your gutter system. This mechanism prevents rot and water damage, which could harm your home's structure.
What Types of Drip Edge Are Available?
There are many styles of drip edge flashing that are accessible. However, three are considered more standard. Each goes by at least one name, which can be confusing, but we've made sure to list their variations. Listed below are the popular options, along with their name variations.
-
Type C: This is the typical "L-shaped" drip edge you may notice on many roofs. Often, you'll see this one referred to as "L-style." This type of drip edge is bent to a 90-degree angle.
- Type D: This one is "T"-shaped and is often called "D-metal" or "T-style." The Asphalt Roofing Manufacturers Association prefers this type of drip edge.
- Type F: This one is also known as the "gutter apron." This option is typically recommended when adding a drip edge to a roof that's already been installed. Type F has an extended top edge, making it easier to install over shingles.
Keep in mind that all drip edges must be resistant to corrosion, galvanized, and non-porous under the building code. This ensures that you get high-quality materials, regardless of which ones you pick. Commonly recommended choices are drip edges made of aluminum, galvanized steel, or copper. Aluminum and steel are more affordable, while copper is on the pricey side.
Cost of Drip Edge Flashing
If you choose one made of steel, it should be galvanized to prevent rust. Since this material is lightweight, it's recommended to choose a minimum of 24-gauge steel. Galvanized steel drip edge costs $3 to $10 per 10 linear feet, depending on your desired style.
Another choice, aluminum, is not quite as strong as steel. Aluminum is the best option when thinking of rust prevention, though, especially for homes in coastal areas. An aluminum drip edge also costs $3 to $10 per 10 linear feet, depending on what style you potentially choose.
Finally, you can choose from "the grandfather of all metals," copper. It gives the roof a unique look and should be a minimum of 0.69 mm, or 20 ounces. Copper drip edge is more expensive, costing $35 to $75 per 10 linear feet, depending on which style you choose.
Is Drip Edge Flashing A Requirement?
The IRC now requires a drip edge to be included in all asphalt roof installations. What code applies to you is dependent on the part of the country you live in, however.
Drip edges weren't a requirement until 2012. They've still taken a backseat when compared to shingles, but they're gaining recognition. Due to their impact on water drainage from roofing systems, drip edges have climbed up the ladder of importance.
Should You Install Drip Edge Yourself?
If you have an idea of what kind of drip edge flashing you may want to pick, getting in contact with a certified roofing professional is the next step.
Hiring an expert to install your new drip edge has numerous pros. In the event of poor installation, water won't be able to flow through the gutters properly. The drip edge should be angled in the proper position to ensure good flow, which can be achieved by a professional. One roof may be different than the next, so it's a great idea to leave roofing tasks to the experts. The last thing you need is an impaired roof from a bad installation job because it takes more money out of your pocket in the long run.
Am I Ready for A New Roof Replacement?
Of course, choosing a new material to add to your roof can be downright confusing. From colors to shapes and sizes, there's a wide variety of possibilities to explore. With so many options to choose from, you can rest assured that there are licensed specialists that can make life easier for you.
