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 membrane roofing.

That way if there s an ice dam at the gutter the water would eventually fall into or behind the gutter but not be able to work its way under the roofing.

Grace ice water shield self adhered roofing underlayment is a premier membrane composed of two waterproofing materials an aggressive rubberized asphalt adhesive backed by a layer of slip resistant coated high density cross laminated polyethylene film.

Installing membrane underlayment ice and water membrane should be installed at least six feet up the slope of the roof from the eaves 6 feet wide in all valley areas and around any heat source such as a skylight chimneystack or flange. An ice dam is a thick rim of ice that originates along the edges of a roof when snow melts and then refreezes. By code only the bottom 3 feet require a backup membrane such as ice and water shield or tar paper but it is a good idea to cover the entire roof with tar paper as well as a backup.

Ice and water membrane must be installed far enough up the slope to cover the first few feet of heated space. Not all high temperature roofing underlayments are the same. Can be left exposed for up to 120 days. Grace ice and water shield ht is an excellent high temperature ice and water barrier that follows in the footsteps of the original ice and water shield but is specially formulated to meet the higher service temperatures that are inherent to metal and tile roofs.

Ice can build up forcing water back up the roof and under the shingles. Slip resistant embossed surface to maximize traction and improve safety. Seals around roofing nails resisting leakage caused by water back up ice dams or wind driven rain. 2 have the experts identified the cause of the problem of the wrinkling.
