SUPPORT FOR ROOF INSULATION IN METAL BUILDINGS AND METHOD FOR INSULATING THE ROOF OF SUCH BUILDINGS ABSTRACT OF THE DISCLOSURE A support grid for roof insulation in a metal building having a roof with a plurality of substantially identical, spaced purlins. The support grid includes at least one cross member adapted to extend between adjacent purlins. The cross member rests on and is supported by a flange of a first purlin and the upper flange of the adjacent purlin. At least one support member may extend longitudinally at angles to the cross members and be engaged therewith. Preferably a first end of the cross member is adapted to rest on the lower flange of a first purlin, and a second end is adapted to be hooked, prior to the application of rigid roofing material to the purlins, over the upper flange of the adjacent purlin toward which the lower flange of the first purlin extends. The method for insulating of the invention includes installing a support grid on the purlins of a roof from above before the purlins are covered by other parts of the roof. Selected insulation material is then placed onto the support grid from above to substantially fill the space between the purlins to a selected level. Then rigid roofing material is fastened to the purlins over the insulation material.
