ABSTRACT:
A knockdown roof platform for use on an inclined roof comprising a table structure an upper flat table top. The table structure has a hollowed area on its underside. Struts are formed integral inside the hollowed area on an underside of the upper flat table top. An upright leg structure is positioned at one end of the table structure having an upper flat table surface positioned in a common plane with the upper flat table top. A hinge connects the table structure and the upright leg structure in assembly together. Collapsible locking brackets further secure the table structure and the upright leg structure in assembly. The collapsible locking brackets are being adjustable to secure the table structure and the upright leg structure in right angular relation thereby positioning the upper flat table top co-planar with the upper flat table top on the table structure. The collapsible locking bracket is releasable enabling the table structure and the upright leg structure to be pivoted on the hinge thus moving and collapsing the table structure and the upright leg structure out of right angular relation relative to one another and into a storage position where the table structure and the upright leg structure extend almost in parallel relation.
