A pitch pocket includes a multi-piece curb that has at least four quarter-circul ar 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 fre e 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 o ther 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 polyuret hane material. 11
