Ice And Snow Roof Membrane

Cut the membrane into 10 15 ft 3 5 m lengths and reroll loosely.

Ice and snow roof membrane.

The purpose of ice and water underlayment is to stop water from passing through the roof system into a home. An ice dam is a thick rim of ice that originates along the edges of a roof when snow melts and then refreezes. Ice and water membrane is needed most to address ice damming issues during the winter. Snow guards for single ply membrane roof snow retention while typically used in very low slope roof situations in many areas single ply roof systems require a roof snow guard system to prevent the snow and ice pack from creeping over the eave and dropping onto people and property below.

Ice and water protectors sometimes called ice and snow shields in cold climates are made with polymer modified bitumen. Press the membrane in place with heavy hand pressure. Apply roof covering material at temperatures of 40 f 5 c or higher. Peel back 1 2 ft 300 600 mm of release liner align the membrane and continue to peel the release liner from the membrane.

Then install regular roofing underlayment tar paper over the top of the drip edge and over the ice barrier and continuing all the way up the roof. Ice and water protector sometimes also referred to as ice and water shield is a waterproof roof underlayment membrane developed to protect vulnerable areas on a roof from ice and water damage. In turn this water can creep up under the shingles causing a roof leak.
