ROOFING

When we provide a homeowner with a roof replacement proposal the second item on the form addresses the replacement of rotten roof decking. At yesterday's job we unfortunately had to inform the homeowner that the entire roof deck needed to be replaced and the reason was inadequate ventilation. A 2x4 was inserted at the edge of the eave to act as a stop to prevent the blown in insulation from going into the soffit area. This also created a stop that prevented cool air from flowing from the soffit vent into the attic and purging the hot air from the attic space. The excess heat buildup caused the plywood deck to "cook" and delaminate. Our solution was to turn the 2x4 block at a 45 degree angle to act as a curb to hold the insulation and still allow air flow into the attic space.
