Ice and water shield is a synthetic roofing underlayment used to protect the roof deck and underlying materials from the damaging effects of water and ice. It is installed in valleys, eaves, and rakes, and around any protruding objects on the roof. The shield is typically composed of two layers of asphalt-saturated felt bonded together with a polymer resin.
How To Install Ice And Water Shield In A Valley
Installing ice and water shield in a valley is one way to prevent water infiltration. The shield should be installed over the entire length of the valley, and it should extend up the sides at least 6 inches. The shield should be overlapped by at least 6 inches, and the seams should be taped.
-Tape measure -Ice and water shield -Utility knife -Plywood -Staple gun -Staples
- Purchase ice and water shield that is at least a foot wider and longer than the valley
- Cut the ice and water shield to size peel off the backing
- Measure the width and length of the valley
: 1. Make sure the surface is clean and dry before installing the ice and water shield. 2. If the valley is wider than the ice and water shield, you will need to cut it to size. Be sure to make clean, straight cuts. 3. Peel off the backing and place the ice and water shield in the valley, making sure to press it into all the cracks and crevices. 4. Use a roller or a broom to press it down firmly.
Frequently Asked Questions
Does Ice And Water Shield Go Under Valley Metal?
No, the water and ice shield does not go under the valley metal. The shield sits on top of the metal to protect it from the elements.
How Do You Install Ice And Water Shield In Valleys?
Install the ice and water shield in valleys the same way you would install it on a roof – by overlapping the sheets and cutting them to fit. Make sure to seal all seams with roofing cement to prevent leaks.
Does Ice And Water Shield Go In Valleys?
It is possible that an ice and water shield could be placed in a valley, but it is not common practice. The main reason for this is that the ice and water would likely freeze into the ground and become difficult to remove. Additionally, the ice and water would not be as effective at shielding against erosion as it would be on flat ground.
In The End
Installing ice and water shield in a valley is a fairly straightforward process. The first step is to measure the length and width of the valley, then cut the ice and water shield to size. Next, use a trowel to spread adhesive onto the roof decking in the valley, then place the ice and water shield in the adhesive. Finally, use a roller to smooth out the ice and water shield.
