Ice And Snow Roof Membrane

Ice can build up on a roof slope usually at the unheated area at the eaves forming an ice dam that prevents water from draining off the roof.

Ice and snow roof 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 dam leak protection membrane is required along the eaves of roofs in parts of the united states where ice dams have a history of forming. Ice and water membrane is needed most to address ice damming issues during the winter. Install the ice barrier membrane according to the manufacturer s instructions with the drip edge installed on top of the membrane.

Cut the membrane into 10 15 ft 3 5 m lengths and reroll loosely. 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. 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. Apply roof covering material at temperatures of 40 f 5 c or higher. An ice dam is a thick rim of ice that originates along the edges of a roof when snow melts and then refreezes.
