Drip Edge Corners: What They Are and Why They Matter

If you're in the process of installing a new roof or replacing an old one, you may have come across the term "drip edge" before. This metal flashing is a crucial component of any roofing system, as it helps protect your home from water damage by directing rainwater away from the fascia and into the gutters. However, drip edge corners are an often-overlooked part of the installation process that can have a big impact on the effectiveness of your drip edge.

So, what exactly are drip edge corners? In simple terms, they're the pieces of drip edge that are installed at the corners of your roof. These corners can be tricky to navigate, as they require precise cutting and bending of the drip edge to fit snugly against the ceiling and the fascia. But getting them right is important for ensuring proper water drainage and preventing leaks.

One common issue with drip edge corners is that they're sometimes cut too short, leaving a gap between the edge of the drip edge and the roof. This can allow water to seep in and cause damage to your roof deck and the underlying structure of your home. To avoid this, it's important to take accurate measurements and make precise cuts when installing your drip edge corners.

Another problem that can arise with drip edge corners is that they can become bent or misshapen over time. This can happen as a result of wind, debris or other factors and can compromise the effectiveness of your drip edge. If you notice that your drip edge corners are damaged, it's important to have them repaired or replaced as soon as possible to prevent water damage to your home.

In addition to protecting your home from water damage, drip edge corners also serve an aesthetic purpose. When properly installed, they can provide a clean and polished look to your roofline. This can increase your home's curb appeal and even boost its resale value.

Overall, drip edge corners may seem like a small detail, but they play an important role in the overall effectiveness and appearance of your roofing system. So, if you're in the process of installing or replacing your roof, be sure to pay close attention to the installation of your drip edge corners to ensure that they're properly fitted and functioning as they should.

When installing a drip edge on a roof, it is important to pay special attention to the corners. The corners are the most vulnerable points where water can seep through, causing damage to the roof and the structure below. Here are some tips on properly installing drip edge corners to ensure your roof is protected from water damage.

Cut the drip edge to the proper length

Before you begin installing the drip edge, make sure that you have measured the length of the roof edge and the drip edge corner cut to the correct length. This will ensure that the drip edge fits properly and doesn't leave any gaps.

Overlap the drip edges at the corner

When you get to the corner, overlap the two sections of drip edge by at least 2 inches. This will create a watertight seal and prevent any water from seeping through.

Cut a notch in the top edge of the lower section

Use a tin snip to cut a small notch in the top edge of the lower section of the drip edge. This will allow the top edge of the upper section of the drip edge to fit snugly into the notch, creating a secure joint.

Secure the drip edge with roofing cement

Apply roofing cement along the joint where the two sections of drip edge overlap. This will provide additional protection against water penetration.

Install the gutter

Once the drip edge is installed, you can then install the gutter. Make sure that the gutter is securely fastened to the fascia board and that it slopes slightly towards the downspout to ensure proper drainage.

By following these tips, you can ensure that your drip edge corners are properly installed and that your roof is protected from water damage.
