I'm quoting a job that has an existing array with L feet bolted down to a shingle roof with no flashings. I want to match the height of the existing array. Also some modules are being worked in around skylights where it is unlikely that room would be available for flashings to center over rafters.

I've always used flashings. Would it be completely crazy to follow suit of the existing array and bolt L feet straight to the shingle roof with good roof sealant? If so, how would you seal it?

Thanks,

Drake
