Research by the Florida Solar Energy Center showed that light-colored and reflective roofs reduced cooling energy consumption by 18%-26%, reduced peak energy demand for cooling by 28%-35%, and reduced attic temperatures by 20°F.
Image
Right - Roofs with simple geometries are less susceptible to ignition from wind-borne embers getting lodged on the roof in a wildfire.
Image
Right - Solar photovoltaic panels are installed on the highest parts of the roof to avoid being shaded by other parts of the house.
Image
Right - The simple rectangular design of this home provides a large expanse of roof for solar panels.
Image
Right – Flashing is installed around chimney, skylight, vents, dormers, in valleys and at eaves
Image
Right – In wildfire prone areas, using a flat soffit with venting on the fascia instead of an angled soffit with down-facing venting reduces the risk of catching rising embers.
Image
Right – The heavy roof underlayment was wrapped over the edges and down onto the walls, providing a continuous air barrier at this critical juncture; the second story will have narrow overhangs, matching the existing architecture style in the neighborhood

Wind path and uplift force for gable ended roof, hip roof, and pyramidal (another variant of a hip) roofs
Image
Wrong - An open eave with no soffit covering can trap rising hot air and embers from a wildfire.
Image
Wrong - If the soffit is applied directly to the rafter eave, it forms a sloping soffit, which creates a pocket that can trap hot air and embers from a wildfire.
