Expert Verdict Reviewed by the SuperArbor Pro Desk

Corners are the most common leak points on single-ply roofs, so preformed universal corners are worth the added material cost over field-fabricated patches. Weld with even overlap and probe every seam after cooling. Keep corners in original packaging and out of direct sun until use to preserve weldability.

Heat-welding equipment and hot membrane can cause burns; wear protective clothing and follow fall-protection rules on the roof.
