How to Seal Eaves

In addition to aesthetics, there is another reason to seal eaves. Sealing eaves will help keep birds, bats and insects from invading your roof.  An eave liner can be used for the most eye pleasing appearance.

Step 1: Measure Eave Lengths

Before you order the eave lining, measure the length of the roof eaves you will be sealing to ensure you order the right amount. Make a diagram of the areas and note the length of each one separately. Allow for waste when you purchase the lining.

Step 2: Cut Lining

Cut the lining sheets to the lengths you need.

Step 3: Install Lining

The lining is installed by nailing it into the trimmers on the overhang of your roof. The lining requires one nail on each trimmer to stay secure. The nails should be at least 12 mm from the edge of the lining. When butting two liner pieces together, try to make sure the butt is in the center of the trimmer piece with 2 nails, one 12 mm or more from each butted edge. If the butted edge cannot be on a trimmer, use a PVC H-mold to join the parts. The edge of the liner where the PVC H-mold is installed should be at least 200 mm away from the trimmer on either side. All liner edges must be supported with either nails or a PVC H-mold.
