Step 1

Installing roof drip edge flashing properly

Install roof drip edge along the eaves, add underlayment, then place drip edge along the gable end. The best way is to install the roof drip edge only along the eaves first, then place ice-and-water barrier (in the snowbelt) or felt paper (underlayment) over the drip edge. This lets any water that gets on the roof run down the underlayment and over the drip edge.

Once all the underlayment is applied, go back and place the roof drip edge flashing along the gable ends of the roof. Covering the ends of the ice-and-water barrier or felt paper with drip edge ensures that windblown rain that gets under the shingles will run over the underlayment, not on the sheathing. The drip edge also helps hold down the felt paper to keep it from blowing off before you install the shingles.
