How Many Wrong Things Do You See

Installing Drip Edge On Your Roof!

I wanted to include examples of some mistakes that you want to avoid and explain why these will cause issues. In the image above, the handyman is doing several things incorrectly.

First of all, the drip edge that he is using has a vertical leg that is way too short to fit inside the gutter. This, in and of itself, isnt necessarily wrong, but it is a combination of mistakes that make it a bad install.

The whole point of installing drip edges is to direct the water into the gutters and away from the fascia and house foundation. To correct this situation, make sure to purchase drip edge flashing with a long enough vertical leg to reach the gutter. If the gutters have been installed too low, they may need to be raised and corrected.

If you find yourself in a situation where you are using drip edging that can not reach your gutters, you can still increase your protection by using the proper drip edge to fascia distance. Unfortunately, this is the next mistake that he is making.He is placing the drip edge right against the fascia. If spaced properly, the drip edge would still provide some protection despite the gutter issue. But installed this way is going to result in surface tension water running down the face of the fascia board and behind the gutter.

Why You Need A Roof Drip Edge

Without the installation of a drip edge, water can wick into the edges of the roof sheathing and cause the roof to develop rot and/or mold. In worse cases, a leak will develop in the ceiling or along the walls.

Although it is not the intention, drip edge flashing will also provide protection for the fascia board. Because the drip edge directs the water directly down and into the gutters, the back of the fascia is protected from excessive moisture. This helps to extend the life of the wood.

Another benefit that wasnt intended but has been a useful outcome from installing a drip edge is that it prevents rodents, squirrels, and birds from being able to access the attic space via the builders gap. If you have ever had a family of squirrels living in your attic, you can appreciate this extra bonus.

I always swap out the old screw with a fresh one and then apply a dollop of 100% silicone over the screw for extra security.
