Roofing structure and method

Roofing component for pitched roofs comprising:

• a flexible base,
• ranks of vanes extending outwardly from and integrally formed with said base at a predetermined angle, said angle being other than substantially 90 degrees said vanes being thin such that they have a high thermal impedance in the plane thereof and being mounted substantially parallel to each other and in overlappingly spaced tiers so that a next upper vane shades the vane below it and provides space for air circulation between themselves to keep heat from penetrating the roof and, said vanes being resilient at least so as to absorb the impact of falling material, and
• said base having a portion thereof free of said vanes so as to provide an overlapped area for installation on a pitched roof with at least one further of said roofing components.

A method of protecting a roof from solar radiation comprising intercepting said solar radiation a spaced distance above said roof by a rank of spaced overlapping thin vanes joined by root portions to an mounting element at an angle, said angle being other than substantially 90 degrees, said thin vanes reflecting at least a portion of said solar radiation and providing a high thermal impedance to solar radiation converted to thermal energy in said vanes, an upper vane casting a shadow on at least the root portions of a lower vane to provide a cooler area thereof, and circulating air in and about said spacing between said vanes.

A method of installing a roll of roofing covering on a pitched roof having a peak, comprising:

• providing roofing components, each roofing component having a flexible base and ranks of overlapping thin vanes secured to said flexible base at an angle, said angle being other than substantially 90 degrees, there being am upper vane, lower rows of said thin vanes and a bottom, said flexible base having at least one underlapping edge extension tapering from the upper vane at one edge to an end, and an overlapping portion opposite said one edge and interlocking tongue and groove formations on said edges, respectively,
• securing a first row of said roofing components along and adjacent said peak,
• rolling said first row from the bottom toward said peak to provide a space, inserting said tapered edge in underlapping relation to said overlapping portion of said first row of roofing components and interlocking the groove on one of said components with the tongue on the adjacent one of said components, and repeating the rolling, inserting and interlocking steps for each lower row of roofing elements.

Roofing component for pitched 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 said first angle being other than substantially 90 degrees, said fins being spaced substantially parallel to each other and overlap to shade portions of the lower fins from the sun and to provide air circulation and between fins, said fins sluff-off 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.
