Other Roofing Considerations

“Drip edge” (shown above) is L-shaped aluminum strips which fasten above the fascia board and under the lowest course of shingles.
It ensures that rain flows from shingles into gutter and not behind it, or underneath roof decking.
Drip edge is optional. Many builders don’t use it, relying instead on shingles to overhang the gutter and direct the flow of water.
Your roofer will charge extra to install drip edge. I haven’t used it myself, lately. As long as the bottom course of shingles sufficiently overhangs the gutter, you should be ok.
Drip edge is fairly cheap, however, and it does add some extra protection. You may consider it low-cost insurance.
The v-shaped section of your roof is known as a “valley.” | |
