That¹s what came to my mind, as well, based on the description.

Re: [RE-wrenches] Pitched EPDM Roof Attachment
Carl, In the past we have had 8"x8"x 1/4" aluminum plates made up by the local machine shop for about $9 each and used them to distribute the compression for L feet on SIP roofs. It works very well and allows you to adequately tighten the lags and not compress the foam. For more specifics give me a call.

Re: [RE-wrenches] Pitched EPDM Roof Attachment
Hi Carl, Have you looked at the DPW easy feet. Very large foot that shouldn't compress the foam. You may want to use more feet to distribute the load as well. They may be able to give you some help on the calcs. jay peltz power On Sep 8, 2009, at 1:04 PM, Carl Adams wrote: Hello Wrenches, I have a job on a 3.5/12 pitched rubber roof.
