Installing Flashers® brand roof jacks
Installing pipe flashing with Flashers® makes custom fabrication and time-consuming fittings a thing of the past. Flashers require no special tools or complicated installation methods. The rubber cone is clearly marked with pipe dimensions, in both inches and millimeters, so it can be easily customized with tin snips or scissors.
See it in action, two ways:
Quick look (30 seconds): The whole install at a glance, from measuring to the finished install.
Full walkthrough (about 1½ minutes): Every step up close, including reading the size markings, trimming to fit and sealing with urethane or silicone sealant.

Step-by-Step How to Install Flashers® Roof Jack
1. Cut
Cut the Flashers® rubber cone at the pipe outside diameter (OD) marked on the flashing. The marked sizes make it easy to select the correct opening for the pipe. The opening is approximately 20% smaller than the pipe’s outside diameter, allowing the rubber cone to stretch tightly around the pipe and create a secure seal.
2. Slide
Slide the Flashers® rubber cone down over the pipe. If needed, use water as a lubricant to make installation easier. Work the flashing down until the aluminum base is positioned properly on the roof surface.
3. Form
Form and bend the aluminum base of the Flashers® to match the surface and profile of the roof. Work the aluminum carefully so it conforms closely to the roofing material. For sharper angles or tighter profiles, use a blunt-edge object to help shape the base without damaging it.
4. Seal
Apply silicone sealant between the Flashers® pipe flashing and the roof surface. Press the aluminum base down firmly so it sits tightly against the roof and the sealant forms a continuous seal around the flashing. Also run a bead of sealant around the top of the rubber cone, taking extra care to fill and seal on pipes with vertical seams.
5. Fasten Down
Fasten the Flashers® securely to the roof using weather-resistant fasteners to complete the seal. Space the fasteners approximately 1 to 1½ inches apart around the aluminum base to help maintain a tight, secure seal.
