Patent number: 8984822Abstract: A roof-penetrating pipe is covered with a sealing pipe. An annular part overlies the roof-penetrating pipe and a downward extension fits into the roof-penetrating pipe to center the sealing pipe. A flexible seal has an upper part tightly gripping the sealing pipe. A compression ring compresses the upper part against the sealing pipe. The flexible seal is slid downward on the sealing pipe. A base on the flexible seal is secured to the roof. A roof penetrating pipe which is difficult to seal or which cannot be sealed due to corrosion, breakage or oxidation is covered with a cover sleeve apparatus. The cover sleeve provides a smooth sealing surface for application of a standard roof pipe flashing device. The cover sleeve is manufactured from materials to withstand the elements and to meet industry standard sizing.Type: GrantFiled: September 24, 2013Date of Patent: March 24, 2015Assignee: Lifetime Tool & Building Products, LLCInventors: Roger M.
