Heavy rain happens regularly in the Delaware Valley. To ensure that your roof is shedding water correctly, you need a drip edge. If your drip edge is damaged or missing, then you’ll want to install a new one. If your old roof drip edge is made of galvanized metal, you may want to replace it with a low-maintenance vinyl drip edge. Make sure that you follow the directions for how to install a roof drip edge closely. Proper installation is essential for preventing water from reaching the roof deck or the fascia boards.
Learn How to Install a Roof Drip Edge
- If old drip edges are present, remove them by carefully lifting shingles just enough to expose the drip edge.
- Locate the nails holding down the old drip edge and pry them out with the pry bar or hammer.
- Pull old drip edge pieces.
- Install the new drip edges on the eaves first.
- Slip drip edges beneath the felt underlayment and shingles. Each piece should overlap the other by at least 1 inch.
- Drip edges should extend beyond the roof decking by 3/4 of an inch.
- Nail them in place with roofing nails.
- Cut off ends flush with the roof.
- Apply some roofing cement on top of drip edge and press the shingles and underlayment against the adhesive.
- After completing the eave edges, begin work on the gable edges.
- Drip edging on the gable edges goes over the felt underlayment but beneath the shingles.
- Overlap the gable drip edge pieces by 1 inch or more. Make sure the overlapping edges are in the same direction as the water flow.
- Nail the edges in place.
- At the peak of the gable, cut one drip edge even with the roof. Cut the top piece on the other side 1 inch or more beyond the roof. Bend it over the other piece.
- At the bottom of the gable, place the gable drip edges over the eave drip edges.
