Install the underlayment in all valley areas.
Install Valley Metal.
Nail every 6 inches on both sides of the valley. Make sure the valley is centered in the middle.
Overlap valleys 12 inches. Install silicone on all valley laps.
Cut the lock of your valley where it will overlap to make the shingle installation easier.
Once all valley and drip edge is installed, you are ready to install underlayment on the entire roofing area.
On this project, the entire roof is being installed with ice and water shield because it is a low-sloped roof. This is not necessary on all roof projects.
The underlayment will go over the drip edge and valley flanges.
Once all the underlayment is installed, you can then install all endwall and gable metal flashings.
