Putting down ice on roof.

If you see icicles hanging from your roof you most likely have an ice dam. Install the ice barrier membrane according to the manufacturer s instructions with the drip edge installed on top of the membrane. If dams are a serious threat to your roof the problem is usually due to poor ventilation. In colder regions a good practice is to cover the first 3 feet 36 inches or 0 91 m of roof over heated space with ice and water protector.

Begin at a lower corner of roof parallel to the eave and flip the whole sheet over so the adhesive side with release film faces up. Made of polyethylene and rubberized asphalt this membrane prevents water that has slipped under shingles from penetrating to ceilings below. An ice dam is a hump of ice that forms at the edge of a roof under certain wintertime conditions. These dams can tear apart your home so limit them by keeping your roof clear of snow.

Peel both sides of the release film completely off. Ask this old house general contractor tom silva explains the best ways to keep your roof and gutters free from those dreaded ice dams. See below for a shopp. First any time you re roof your home it is an opportunity to install an ice and water shield type of membrane around the bottom edge of the roof.

Cut waterguard rain ice to a convenient length and dry fit the membrane to the roof before removing the release film. The calcium chloride will eventually melt through the snow and ice and create a channel for water to flow down into the gutters or off the roof. If necessary use a long handled garden rake or hoe to push it into position. The minimum is typically 2 feet 24 inches or 0 60 m above the vertical projection of the inside of the exterior wall.

The valleys should then be covered with metal flashing or weaving. Snow guards are like corrals that mount on the edge of a roof. An ice dam can damage both your roof and the inside of your home. All overhangs should also be covered.

Required by code in many places this rubber or asphaltic membrane will help guard against water intrusion inside of your home if ice damming occurs. Lay the hose onto the roof so it crosses the ice dam and overhangs the gutter. Ice dams happen when ice melts trickles down the roof then freezes again. They hold frozen precipitation in place causing the snow or ice to melt or slide off a portion of roof in small pieces rather than dangerous chunks.

First your roofers should lay down an ice and water shield over the entire roof.
