Larry:
I was at the Midwest Roofing Contractors Association show a couple of
weeks ago and one of the vendors in the exhibit hall was OMG Roofing
Products.
Would this product be applicable to your needs?

*_Excerpt From Product Cut-Sheet_*:
/OMG PowerGrip is a roof mount system designed to secure rooftop solar
racks and other equipment to roofs covered with thermoplastic (TPO and
PVC) roof's membranes. PowerGrip provides a secure connection directly
to the roof deck or structural members. Once heat welded in place,
properly installed PowerGrips virtually eliminate rack movement and
remain watertight. Factory fabricated PowerGrips are easy-to-install and
can be made with any TPO or PVC membrane on the market for 100%
compatibility with the roofing system. Since they eliminate the need to
cut open the roof down to the deck, PowerGrips help save valuable time
and labor. In addition, PowerGrips can be used with most solar rack
systems currently available. /

Hello Wrenches,
Installing rail mounted PV array on a 2 1/2 / 12 pitch EPDM
residential roof. It's a flat section of roof in the middle of the
house. Need to keep it low so would like to use 3" or 4" Unirac
standoffs. The standard 1-6" peel and stick witches hat is fine for a
7" standoff but too tall for the 3-4" standoff. Unirac and Oatey have
advised against using the Oatey aluminum flashing although the roofer
who did the roof said it would be OK using seam tape between the Oatey
and the EPDM. Another roofer I know has said absolutely not.
I did find a rubber Masterflash (6" x 6" base) that's a good fit but
all their images show it used on metal roofs only and it's not a peel
and stick. Can I use it with seam tape and/or caulking.
Do I just need to go with the 7" standoff and the standard peel and
stick witches hat and forget the low profile?
Or is their some other system out there (roof attachment/flashing)
that would keep it low. The ridge height is already at the 35 ft limit
and the upper row of mod's would go above the ridge with the 7" standoff.
I will work with a roofer but would like to figure this out before
just turning it over to the roofer
Very much appreciate any thoughts.
Thank you and Happy New Year to you all.
