This home like most did not have proper intake eave edge or soffit vents and proper exhaust venting. So, after removing the old roofing material prepping the roof deck including lifting up the decking in strategic locations in order to install insulation baffles since the this home has a cathedral ceiling and the insulation under the roof deck was blocking proper airflow.

Dennison Exterior Solutions Winter Guard Ice & Water Shield

Dennison Exterior Solutions & CertainTeed’s WinterGuard waterproofing shingle underlayment is the solution for winning the battle against water penetration in your roof’s most vulnerable places. WinterGuard is a composite material of asphalt polymers, formed into a rolled sheet. The asphalt makes it vapor-tight, and the polymers make the asphalt elastic and sticky. This protective barrier is able to stretch and seal around nails driven through it. Placing WinterGuard a minimum of 24″ past the interior wall line at the eave provides your first line of defense.

Dennison Exterior Solutions installs Winter Guard six feet up the roofline from all eave edges, where all lower roofs meet any walls and around all roof ‘ shingle penetrations such as furnace / water heater vent stacks, soil pipes, chimneys, antenna satellite fasteners, skylights and any other protrusions through the roof. This process eliminates all potential future call-backs.

Dennison’s Winter Guard seals the roof against infiltration of water into the home due to ice dams and wind-driven rain that also seals water-tight around each nail that is driven through it. The sand surface of Winter Guard also provides a huge safety factor for installers while walking on top of the shield.
