Graham, Mo, Jerry, Tom
Thanks so much for the info. I appreciate it.
Tom and Grahams comments make one wonder if the standoff and flashing
method is really that much better than simply applying on top of the
comp shingles. I have seen EPDM last a long time in other
applications (pond liners) - especially out of the sun.
Has any one looked at the relative costs of re-roofing a flashed
standoff mounted array vs. a foot on comp shingles mounted array?
And then compared that to the likelihood of leakage of each method?
Any final thoughts before I order the parts?
Thanks again,
Jeff
