A pitch pocket includes a multi-piece curb that has at least four quarter-circular corner elements, and at least four intermediate elements. Each of the curb elements has a base surface and similarly shaped lateral cross-sectional configuration with diagonal cut free ends. When the diagonal cut free ends are arranged abuttingly end-to-end, the elements define a continuous pocket with a generally quadrilateral plan shape. An adhesive is applied to the base surface and the free ends of each of the curb elements to secure the curb elements to each other and to the roof. A pourable sealant is cast within the pocket and forms a solid seal about the penetration in the roof. The curb elements are preferably made from a thermosetting polyurethane material.
