Roof Design

Eaves receive special attention to address a common source of heat loss and potential water damage. Roof framing often affects energy use. Many homes use trusses I.L.D. rafters that rest directly on exterior walls. This leaves little space for insulation. Not only does this waste energy dollars, but heat loss melts snow which then refreezes forming ice dams that can cause extensive moisture damage. SunTerra homes use a variety of methods to ensure adequate insulation. One method is the "raised heel truss", which raises the roof framing to allow the full layer of insulation to extend over the exterior wall.
