Herein, what is flashing on a wall?
Flashing refers to thin pieces of impervious material installed to prevent the passage of water into a structure from a joint or as part of a weather resistant barrier system.
Likewise, how do you install drip edge? 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.
Also to know, how do you install flashing on a roof?
Here's how to do it right the first time:
- Cut step flashing pieces to be 10 in. wide and 2 in.
- Nail flashing to roof deck only. Nail through flashing into shingle, do not extend flashing above top of shingle and nail, or flashing will angle up.
- Cover tops of step flashing with house wrap and siding.
What are the different types of flashing?
Types of flashing Sill flashing: Concealed under windows or door thresholds to prevent water ingress. Channel flashing: U-shaped channel used where the edge of a tile roof meets a wall. Through wall flashing: Directs water to weep holes by spanning the thickness of the wall. Cap flashing: Above windows and doors.
