<p>This Architectural Drawing is Roof Floor Builders work plan. A roof plan includes <strong>roof dimensions, specifications for roof pitch/slope, the placement of vents and drainage, and material specifications</strong>. It may also include framing details. <strong>A basic rafter roof is made up of rafters which rest on horizontally placed plates at the top of each wall</strong>. The top ends of these rafters typically meet at a ridge beam, however in some cases they can butt directly to another rafter, forming a couple (pair of rafters). All roofing systems <strong>rely on an overlap to shed water and resist wind uplift</strong>. Asphalt shingles are nailed to each other and to the roof deck. Additional weatherproof insurance is provided by strips of factory-applied adhesive. The adhesive is heat-sensitive, which makes the shingles self sealing.
