The drip edge is an often overlooked but crucial part of your roof. Installed along your roof’s edges, this thin metal or plastic strip helps to direct water into the gutters, preventing it from seeping behind them or going underneath the roof. This protects your fascia boards and lowers the risk of ice dams in colder climates, and it could spare you from costly water damage repairs down the line. Here’s a quick tutorial on how to install a drip edge if you’re putting one in for the first time or replacing an old one. However, it’s important to know how to test a drip edge roof installation too.
Types of Drip Edge Materials
First, you’ll need to figure out which type of drip edge roof you need to install. There are two main types of materials: metal and plastic. Each option has pros and cons in different areas and situations.
Metal Drip Edges
The most common and durable metal drip edges are made from galvanized steel, aluminum, or copper. They look sleek and professional and offer excellent longevity and resistance to weather and UV damage.
Plastic Drip Edges
Plastic drip edges are a little less common but offer unique benefits. They’re lightweight and easy to install, corrosion-resistant by nature, and come in various colors to match your roof. However, since they may not be as durable as their metal counterparts, they’re better for milder climates.
Tools and Materials Needed for Installation
Having all your tools and materials ready before you start will make the installation process smoother. To install a drip edge, you’ll need the following tools and materials:
- Chalk line
- Drip edge material, measured and cut to fit your roof
- Hammer or nail gun
- Ladder
- Roofing cement
- Roofing nails
- Safety gear (gloves, safety glasses, sturdy footwear)
- Tape measure
- Tin snips
Step-by-Step Guide To Installing a Drip Edge
If you’re uncomfortable working on your roof, it’s best to hire a professional to install your drip edge. However, the process can be a manageable do-it-yourself (DIY) project for many homeowners. Here’s a step-by-step guide to help you through the process.
Preparing Your Roof for Drip Edge Installation
Before you begin, inspect the roof edge for any damage or rot and safely remove any debris or old roofing materials. Confirm that the edge is straight and level, using a chalk line to mark a straight guide if necessary.
Positioning the Drip Edge
To position the drip edge, start at a corner of the roof and slip the wide, fat flange of the material all the way under the first course of shingles. Be sure the outer edge extends beyond the fascia board by about 3/4 inch. If it doesn’t, pull the drip edge slightly out from under the shingles.
At corners, overlap the pieces by about 2 inches for a watertight seal. Use 45-degree miter cuts for neat, effective joints.
Securing the Drip Edge
Properly securing the drip edge is essential to forming an effective water barrier. Apply a continuous bead of roofing cement along the top of the drip edge, then press down on the shingles.
Next, nail the drip edge in place using roofing nails every 12 inches. Drive the nails straight and flush with the drip edge surface.
Installing Drip Edge with Roofing Felt
If you’re installing a drip edge as part of a new roof or re-roofing project, you’ll need to consider how it interacts with the roofing felt or underlayment. Install the drip edge under the felt at the eaves (the lower edge of the roof) and over the felt at the rakes (the sloped edges of the roof).
Common Mistakes To Avoid During Installation
To ensure your drip edge performs as intended, avoid these common installation mistakes:
- Failing to overlap pieces properly
- Forgetting to seal joints and overlaps
- Installing the drip edge too close to or too far from the fascia
- Neglecting to clean and prepare the roof edge
- Using the wrong type of nails or an improper nailing technique
Maintaining Your Drip Edge
Once installed, a drip edge requires minimal maintenance. However, you should still follow these tips to keep it running effectively.
- Check for loosening nails or gaps: If a nail or gap has come loose, reseal it as necessary.
- Clean regularly: Cleaning your gutters and removing debris accumulating on or near the drip edge can help prevent water backup. Clogs and backups can affect the drip edge’s performance.
- Inspect once a year: Check the drip edge for signs of damage or corrosion.
Troubleshooting Drip Edge Issues
Even with proper installation, you may encounter issues with your drip edge over time. Common problems include the following:
- Gaps between the drip edge and fascia
- Loose or missing sections
- Rust or corrosion on metal drip edges
- Water seeping behind the drip edge
When To Replace Your Drip Edge
While a well-installed drip edge can last for many years, you may need to replace it in any of the following situations:
- The drip edge shows significant signs of rust or corrosion.
- There are large gaps or separations from the roof edge.
- The drip edge is bent or damaged beyond repair.
- You’re replacing your roof or gutters.
If you’re replacing your drip edge, it may be worth it to install roof flashing as well. We’ve found that leakproof flashing is the best type of roof flashing. However, it’s important that you know exactly what roof flashing is before investing your time and money.
