A roof vent and a roof structure are described. A roof vent can include a baffle with a cross-section where a first portion extends upward from a bottom plate and a second portion extends from the first portion to define a space between the bottom plate and the second portion. A roof structure may or may not have a roof deck, and comprises a plurality of roof cover elements with a radiant barrier layer underneath the top surfaces of at least some of the roof cover elements. In another embodiment, a roof structure may comprise more sheathing layer vent members than roof cover layer vent members. In yet another embodiment, a roof structure may comprise a layer of roof tiles with at least one vent member, the vent member comprising lateral end portions of a base member with a non-planar profile to engage a similar profile of an adjacent roof cover element.

The roof structure of claim 1, wherein the at least some of the roof cover elements comprise non-photovoltaic roof tiles or shingles. 7. The roof structure of claim 6, wherein the at least some of the roof cover elements comprise non-photovoltaic roof tiles, wherein the non-photovoltaic roof tiles comprise at least one of clay, metal and concrete. 8. The roof structure of claim 1, wherein at least some of the roof cover elements comprise steel. 9. The roof structure of claim 1, wherein each of the radiant barriers includes a material that reflects solar radiation, wherein gaps are formed between the material and lower surfaces of plate elements of the roof cover elements below which the radiant barriers are installed. 10. The roof structure of claim 1, wherein the top surfaces comprise a stone coating that is reflective to ultraviolet radiation. 11. A plurality of roof cover elements, at least some of the roof cover elements comprising: a body having an engagement structure for engaging the body or bodies of one or more other ones of said roof cover elements in accordance with a repeating engagement pattern, such that the bodies are configured to collectively cover at least a portion of a roof when so engaged with one another; anda radiant barrier on or within the body, wherein the radiant barrier is underneath the top surfaces of at least some of the roof cover elements, and wherein the at least some of the roof cover elements are each a roof vent member, non-photovoltaic roof tile, or shingle. 12. The plurality of roof cover elements of claim 11, wherein the at least some of the roof cover elements comprises a roof vent member having said engagement structure for engaging the body or bodies of one or more other ones of said roof cover elements in accordance with said repeating engagement pattern. 13. The plurality of roof cover elements of claim 11, wherein the at least some of the roof cover elements comprise non-photovoltaic roof tiles. 14. The plurality of roof cover elements of claim 13, wherein the at least some of the roof cover elements comprise non-photovoltaic roof tiles, wherein the non-photovoltaic roof tiles comprise at least one of clay, metal and concrete. 15. The plurality of roof cover elements of claim 11, wherein at least some of the roof cover elements comprise steel. 16. The plurality of roof cover elements of claim 11, wherein the top surfaces comprise a stone coating that is reflective to ultraviolet radiation. 17. A roof structure comprising: a plurality of rafters;a plurality of battens over the rafters with a roof deck between the battens and the rafters;a field of roof cover elements supported by the battens; anda radiant barrier underneath the top surfaces of at least some of the roof cover elements, and wherein the at least some of the roof cover elements are each a roof vent member, non-photovoltaic roof tile, or shingle. 18. The roof structure of claim 17, wherein the radiant barrier comprises a carrier layer and a material adapted to reflect solar radiation, said material being on at least one side of the carrier layer. 19. The roof structure of claim 18, wherein the carrier layer comprises bubble wrap. 20. The roof structure of claim 18, wherein the material adapted to reflect solar radiation is on two sides of the carrier layer. 21. The roof structure of claim 18, wherein the at least some of the roof cover elements comprise non-photovoltaic roof tiles, wherein the non-photovoltaic roof tiles comprise at least one of clay, metal and concrete. 22. The roof structure of claim 21, wherein the at least some of the roof cover elements further comprise at least one vent member comprising a cover member and a base member joined together and having downslope edges spaced apart, the base member having lateral end portions extending laterally beyond lateral edges of the cover member, each of the lateral end portions of the base member having a non-planar profile conforming to and engaging a similar profile of an horizontally adjacent roof tile.
