Roof Sheathing Help Leak Tight

If your ceiling has a plastic vapor barrier between the drywall and the attic insulation push the insulation aside and look for flow stains on the plastic often water runs to openings in the vapor barrier such as at ceiling light fixtures.

Roof sheathing help leak tight.

Some roof leaks are tough to locate. Use enough water to mimic heavy rains. Sometimes the water shows up at a ceiling spot distant from the leak. Depending on how the roofs join you may have to cut a slot to work it in far enough.

Begin soaking low on the roof just above where the leak is visible inside the house. If you tuck window flashing under the foam sheathing you may create a leak. Flexible roof sealant apply flexible roof sealant black jack roof patch rubberized roof cement from a can or tube to fill holes gaps flashing and loose shingles around roof vent new vent shingles replace worn out roof vent with a new one and shingle around it to provide a better roof leak repair. Nail the drip edge to the roof sheathing at roughly 18 24 spacing intervals using roofing nails.

Points to the installation of ice and water shield along the lower roof eaves protecting against ice dam leaks that are common on un vented roofs in cold weather or snow climates. As described above water collects on the top of windows and is forced to the window s edge where the flashing leads water beneath the foam.
