Roof for a storage reservoir, such as a silo, having a frame with a rigid peripheral element, a central core element and a plurality of tension elements which are distributed about the peripheral element. The central core element includes at least two supports that are mutually connected at an axial distance apart. The tension elements are stretched between each support on the central core element and the peripheral element. The tension element is fixed to the central core element and the tension element such that the tension of the frame is varied by varying the distance of the tension element is stretched between the rigid peripheral element and the central core element.

Roof for a silo comprising: a frame having a variable tension, said frame having a peripheral element that is adjustable in length, a central core, and a plurality of tension elements, said central core having a first support and a second support mutually connected at an axial distance apart along said central core; said tension elements being distributed about the peripheral element; wherein each of said tension elements has (1) a first end attached to said first support; (2) an intermediate section in contact with said peripheral element and positioned a distance d from said first support; and (3) a second edge attached to said second support, such that the tension of the frame is varied by varying the distance d between the intermediate section and the first support; and wherein the peripheral element has a circumference that is adjustable in magnitude for varying the distance d between the intermediate section and the first support.
