[RE-wrenches] Mounting L feet on corrugated metal roof.

Re: [RE-wrenches] Mounting L feet on corrugated metal roof.

Hi John When you say ' corrugated ---with flat spans and ribs-- do you mean what is generally called Grand Rib around here in Va. 8" flat panel with a low 1" wide area in the middle of the flat panel, then a rib 1"+ high, held on to the roof sheathing with hex head screws and sealing washers?

Re: [RE-wrenches] Mounting L feet on corrugated metal roof.

It sounds more like "Grand Rib" rather than sinusoidal. What we normally do is mount the L-Feet directly to the flat metal sections with a healthy amount of sealant, similarly creating a watershed on the uphill side. In my experience, the pad is not necessary. We never crush the rib with an L-Foot.

Re: [RE-wrenches] Mounting L feet on corrugated metal roof.

John, We have done several of these corrugated steel roofs. We like using 3/8" x 8" Hanger Bolts from UniRac part #310025. These are a long custom lag screw designed to have an L foot fastened on it. Allows you to get the L feet above the plane of the ribs so you can place the hanger bolts wher

Re: [RE-wrenches] Mounting L feet on corrugated metal roof.

John. I've used AEE Solar's corrugated roof block with good success.  Since the corrugations rarely line up with structural members you'll need to install blocking for most attachment points. Kent Osterberg Blue Mountain Solar cvso...@aol.com wrote: Wrenches, Do you have any tips

Re: [RE-wrenches] Mounting L feet on corrugated metal roof.

John, If the roofing you are talking about is similar to traditional corrugated, but with flat valleys and ribs instead of a sinusoidal/ curved profile, we just completed an install like that using the Corrubracket from S-5. (it also works for the sinusoidal profile) No L- feet required. The
