flashing for ribbed metal roof
I have been looking for a way to mount collectors or racking on a delta rib metal roof. metal roof are common in this and many western areas. I have found a few options.
S-5 builds that arch Corru Bracket, shown here, for corrugated style roofing. Aztec builds the stainless gasket mount washers for different shapes.
I took the mini sample from Quick Mount PV trimmed it down and shaped it to fit on the rib.
The goal is to have the penetration seal at least 1/2" above the roof to eliminate leak potential. The Quick Mount system for shingle roofs puts the seal about .070 above the roof. On top of the delta rib it is up about 2".
