Yes, all it takes is a screw driver. Each unit has 4 screws that hold it in place by passing through the lead flashing and biting into the pipe. This provides a firm mount. The average time to install is about 15 minutes per unit, and you don’t have to pull up shingles or cut the flashing. Simply cut the unit to fit (unless you ordered a precut unit,) slide it over the damaged flashing and put the screws in place. Its an easy vent repair vs. an expensive vent flashing replacement.
