Drip edge or eave strip is the strip of metal flashing that runs under your shingles along the front side of the eaves of your house. Drip edge can also be installed on the gables/rakes of your home as well. Installing drip edge on the gables/rakes of your home can give your roof a bit more “pop”, particularly when using a black drip edge, as it gives a bold outline of the roof that looks great from the road and adds a bit of curb-appeal. Drip edge is great because it helps support the shingles as they extend past the roof decking. Another great benefit of drip edge is it keeps rain from running down the fascia board, which will prevent rotting and prolong the life of your house’s facia and soffit.
One mistake homeowners make is they use drip edge that is made of galvanized metal. This makes it hard to hold paint well and can even rust over time. A better solution is vinyl coated aluminum drip edge. With this type, you won’t have to worry about it rusting or needing to paint it. Vinyl coated drip-edge also has a more aesthetically pleasing look for your home, rather than galvanized metal.
Drip edge is most commonly replaced when a new roof is installed, although it can be replaced any time. In some states it is now code to install drip edge when new roofs are installed. During cold weather asphalt shingles become brittle so if you are replacing the drip edge without putting on a new roof, it is best to wait for a warm day.
Tools and Materials Needed:
- Tin snips
- Drip Edge
- Galvanized roofing nails
Installing The Drip Edge
- Install the drip edge on the lower part of the roof first (the eaves), then work your way up to the rakes. Make sure the drip edge is under the shingles and felt underlayment on the eaves and over the felt paper (but under the shingles) on the rakes.
- Align one end of the drip edge even with the edge of the roof decking.
- Carefully lift your shingles, and nail the drip edge into the roof decking with galvanized roofing nails.
- On your next piece, be sure to overlap the first piece by at least 2” and nail them in place.
- Cut the last piece on the lower eave flush with the roof decking on the other end.
- Install the gable drip edge over the felt underlayment and on top of the lower drip edge strips.
- Cut and bend the end of the gable drip edge to cover the gap between it and the lower strip.
- Overlap higher gable drip edge over the lower ones by at least 2”.
- Cut and bend the top end of the matching gable drip edge strip so it extends over the roof peak by at least 2″ and overlaps the matching gable drip edge strip.
You should now have drip edge properly installed on your home’s eaves and rakes. This will save you time and money down the road by preventing the facia and soffit from rotting and needing replacement.
