What would be the best way to install the flashing around the electrical service conduit roof penetration. There is the old flashing that was used with the shingles. However, would it be better to remove the old flashing and install a Dektite retrofit? Also, how would you install the exposed fastener metal panel? Thanks in advance for your time and assistance.

Steve, yes, use a Dektite Retrofit for the electrical Conduit. run a full width panel 6" past the conduit (notch for the conduit); apply two rows of good quality butyl tape or silicone caulk across the full width of the panel; install a panel from the conduit to the ridge. thanks for selecting a metal roof. To insure a quality product you should select from a Metal Roofing Alliance member manufacturer. we have all agreed to a minimum quality standard.

+1 Time for a split boot and flashed as Dick says above. Post up some pictures if you can.

Dick, I understand installing a notched panel from the eave to 6" past the conduit. Question: For the panel running to the ridge, is it notched and slipped down over the "eave panel" around the conduit also? Question: If the panels overlap around the conduit do I screw the Dektite Retrofit boot into both panels with wood screws or stitch screws. Again, thank you for your help. Best regards, Steve Jones

Eric, The attached pic shows what I'm working with. A recent storm with a couple of tornados came through and the 2" rigid metal conduit was bent 90? when a large tree limb landed on the service cable. At the time I was replacing the conduit I could have slipped a regular pipe boot over the conduit but I had not decided on a metal roof. I wasn't fully aware of the extent of damage on the roof. I put down 30# roofing felt and covered that with AtticFoil radiant barrier. I'm using 2x4s for purlins and setting them on 1x4 pressure treated boards. Doing this will insure I get good air flow over the roof deck and with the radiant barrier lower the summer cooling costs. If you have suggestions please shout them out. This is my first metal roof. The roof is a simple gable roof with no valleys, dormers, etc. Thank you again for your time and help. Best regards, Steve Jones

Steve, I think you are fine. We make a metal boot (of sorts) to go over the Dektite units in this case to protect the boot from the UV rays.
