We use Quick Mount PV L-Mount but we're switching to IronRidge FlashVue soon. I've seen too many non-flashed solar pool heating mounts work their way loose to trust a mount without a flashing. While PV mounts are different and arguably better, I still prefer a fully flashed method.
That said, I trust the EPDM and Butyl tape gaskets used on some metal roof mounting products, mainly because the surface is different. It doesn't compress the same way a shingle does and it's a clean flat surface. On my own shingle roof I have installed several QuickBolts to secure some steel cables that hold up courtyard lighting. I'm doing it as a bit of a test because of the lateral stresses imposed on the bolt. Only time will tell how it holds up. For now, I don't trust it enough to install it for a paying client.
