Scuff Pads for Rubber Membrane Roofs [RE-wrenches]

[Larry Crutcher, Starlight Solar]

Hello Mike, Welcome to the list.

Back in the 80's I was installing satellite antenna systems for the broadcast and commercial market. I installed many NPR type mounts on flat and pitched roofs. Every install would have a 1/8 rubber high density mat under all steel. Here is a specification for what we used: http://www.bairdsatellitesupports.com/pdfs/rubber_matting_spec.pdf

  > Hi All,

  > I am new to the RE-wrenches listserv, but some people have told me it is the best place to share ideas with other solar installers, so here I am.

  > We are currently in the middle of a commercial install, our first, of a 9.9kW system on a machine shop in New England.  The roof is flat, and has a rubber membrane.  We are using UniRac's RapidRac, and wanted to know what people thought about using scuff pads under the racking system to protect the roof.  It seems that the sharps corners of the racking could cut into / penetrate the membrane under the dead load of the array and in times of heavy snow loads.  Are using pads common?  What materials are used?
