First, cut your underlayment to fit the valley. Using a utility knife, carefully cut the underlayment at its center. Be sure to leave a small overhang in the roof edge. Then fold back the underlayment to tack it into place. You’ll need to apply firm hand pressure while smoothing out the edges to ensure the underlayment seals correctly. If you’re installing asphalt shingles, you may want to choose roll roofing as your underlayment. Roll roofing is acceptable in valleys, but it can crack more easily and is not self-healing around the nails.

To install roofing underlayment in valleys, you’ll need to remove the shingles. This will open the surface for the metal lining. This lining will prevent water from pooling on the roof. As a result, the entire roof will remain watertight. If you’re unsure how to install roofing underlayment in valleys, watch the Brava YouTube channel to learn how to install underlayment in valleys.

Another tip for proper valley flashing installation is to install self-stick underlayment. It’s easier if you have two people working together. Use the adhesive side of the underlayment to stick it to the valley. Make sure to align the edges of the metal flashing so that they’ll stick to the underlayment. Once you’ve done this, you can proceed to installing the roof underlayment in the valleys.

The process of installing roofing underlayment in valleys will differ for different types of valleys. The most common type is the closed valley. This type will go up quickly and provide a clean look. It can be made of standard or laminated shingles. However, it’s important to note that a closed valley will not protect the underlayment as much as an open one. This type will have four layers of material on the roof.

A closed-cut valley is a much easier process than one where the roof is open. Here, shingles are installed on both sides of the valley, with one roof plane overlapping the other. This ensures that no water can seep through the valley and cause damage. Once the underlayment has completely sealed the valley, the roofer installs shingles over the valley. In both cases, the shingles will cover part of the valley and the underlayment.

Felt is an excellent option for roofing underlayment in roof valleys, but it isn’t as water-tight as other materials. Like peel-and-stick underlayment, felt has the potential to crack and lose its volatile organic compounds. Water will seep beneath the felt, and you’ll have to worry about leaks. In addition to water seeping through the valley, snow and ice can also collect here.
