Adam - This is a good topic. We are finding more and more flat roofs with rigid insulation installed over the wood decking to provide cricketing (for drainage) and insulation for the home. Installing standard stanchions is difficult because it is hard to find the rafters and also we need to use a hole saw to cut through the rigid insulation so the base of the stanchion has a solid deck to attach to. Very difficult all around! Nonetheless, we still mainly use Chemlink E-Curbs or work with a roofer to flash and seal.
We have tried a few projects with the Unirac Flashloc RM product: https://unirac.com/flashloc-rm/ All in all, our crews like them although they are expensive. The tricky part is getting the engineering to work out since this type of product can be used to attach solely to the decking. We're also trying out the Anchor Products U2400 that Jeff mentioned. And, we're using the OMG Powergrip product on a commercial project: https://omgroofing.com/products/solar-mounts/powergrip-plus August Luminalt On Wed, Nov 3, 2021 at 1:33 PM Jeff Irish <jeff.ir...@suncommon.com> wrote: > Have a look at U2400s from Anchor Products.
