Abstract
A method for providing a roof structure having a plurality of purlins spaced apart from one another in a parallel arrangement the purlins having top portions is disclosed. A carriage is providing upon which is mounted a roll of support sheet. A first section of the roof structure comprising purlins, a support sheet, insulation material, and hard roofing material is completed. An insulation support sheet having side edges which enable the support sheet to be laid on adjacent purlins is then provided. The side edges are aligned with the top portions of adjacent purlins so that the support sheet can depend from the adjacent purlins. The carriage is moved along the length of the purlins and away from the first section of the roof structure, in which the movement of the carriage pays out the support sheet in a pleated condition having a first width so that the edges of the support sheet are aligned with the top portions of adjacent purlins and the support sheet depends from adjacent purlins. The support sheet is unfolded between the purlins to a second width wider than the first width.
