Abstract
Abstract A roof structure has a supporting base on which a layer of insulating material is placed and over which is a metal layer having water circulating channels. The metal layer is covered by a water proofing layer, the outer surface of which is covered with mineral particles. The roof structure serves both the function of a conventional roof and a solar energy collector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
127 words
A solar roofing structure combining the covering and waterproofing functions of a conventional roof with the functions of a solar energy-collecting panel, which can be used to heat or air-condition the premises it covers, and which comprises: a supporting base; a layer of insulating material on said base; waterproofing cover means of a material selected from the group consisting of elastomers and bitumen, the outer surface of which is covered on its upper surface with mineral particles selected from the group consisting of gravel, glass and ceramic particles; and means separate from said waterproofing cover means defining circulation channels for a liquid, in close contact with and below the waterproofing cover means, and between said waterproofing cover means and the insulating material and in contact with each.
