Roofing elements having vane members

Roofing component for roofs, comprising:

• a flexible base,
• ranks of vanes extending outwardly from and integrally formed with said base at a predetermined angle such that when mounted on a roof, said angle being oriented relative to the sun so as to take advantage of the maximum shadowing at mid-day, said vanes being thin such that they have a high thermal impedance in a plane of said vanes and being mounted substantially parallel to each other and in overlapping spaced ranks so that a next adjacent vane shades the vane below it and provides space for air circulation between said vane members to keep heat from penetrating the roof.

Roofing component for roofs, comprising, a flexible base and one or more ranks of integrally formed thin solar energy absorbing and thermal energy radiating fins extending outwardly from the base at a first angle so as to cast a shadow on an adjacent fin, said fins being spaced substantially parallel to each other and overlap to shade portions of adjacent fins from the sun and to provide air circulation and between fins, said fins radiating heat and being thin so as to impede thermal energy being transmitted to the roof, said fins being flexible and resilient so as to absorb the impact of falling material.
