Which statement about drip edge placement is correct?

• A. Under the felt at the eaves
• B. Over the felt at the rake
• C. To the sheeting
• D. All of the above

Answer: (D)

Drip edge placement is about directing water away from the roof edge and protecting the roof deck, and the exact layering can vary by edge and installation method. At the eaves, the drip edge is often set so that water is guided into the gutter, which in some systems means positioning the edge under the felt or underlayment so the bottom edge remains exposed to shed water outward. At the rake (the sloped side edges), it’s common to place the drip edge over the felt so the edge terminates cleanly and water is prevented from wicking under the roof coverings at that corner. In all cases, the drip edge must be firmly fastened to the roof structure—typically nailed to the sheathing or fascia—so it stays in place and provides a reliable edge for the roofing materials to overhang and shed water. Because these arrangements are all used in practice depending on edge and layer order, all of the described placements are correct in their proper contexts.
