An outside corner patch for TPO roofing is formed from a circular piece of TPO membrane material being vacuum formed to define an array of flutes that extend from the center of the piece toward its edges. The flutes form ridges and valleys that generally are shaped as conical sections with the apex of the conical sections located at the center of the patch. The number and size of the flutes is optimized in such a way that, when the flutes are stretched flat, the patch conforms to and fits flat against the surfaces of an outside corner formed by the intersection of a roof deck with an upward protrusion from the roof. The TPO outside corner patch is applied over the corner and thermally welded to surrounding TPO membranes on the roof deck and the protrusion to form a watertight seal at the outside corner.
