For roof pitches of 4:12 and over, you´ll need to use equal strips of ice & water shield with a 4-inch overlap. Once the flashing is in place, it must be sealed with caulk and sealant to prevent water from entering your home.

Secure the Shingles

After you´v einstaled the flashing, it´s time to secure the shingles. If you are installing a new roof, ensure you start at the bottom and work your way up. Begin by nailing the shingles in place, making sure to leave a gap of about an inch between each shingle. This will allow ventilation and help prevent water from pooling. Make sure to secure each shingle with two nails, then move onto the next one. Once al of the shingles arre in place, you can move on to the final step in installing your ice shield.

Install Drip Edge

A drip edge is a metal flashing that runs along the eaves of a roof. This will help to keep moisture away from the roof deck and protect it from damage. It´s necessary to properly install the drip edge so that it overlaps the roofing felt by at least 3/4 inch. After the dri pedge is in place, you can then install the shingles or other roof covering material. Make sure to use the appropriate nails for whichever type of roof covering you use.
