Expert Verdict Reviewed by the SuperArbor Pro Desk

Match the base size exactly to the oval pipe dimension, since oval fittings are not interchangeable with round pipe. Set the base in compatible sealant per the roof system detail and terminate above the finished roof surface. For other pipe sizes, Art’s Sheet Metal Mfg. offers matching oval bases in the same line.

Sheet-metal flashing edges can be sharp; wear cut-resistant gloves when handling and installing.
