I was all set for a company to put solar PV panels on my roof. I had told the sales guy it was a metal roof, and he indicated that should not be a problem. But it was determined that they cannot install to my roof at all, even though their company has installed panels to other metal roofs in the past. The problem is that those metal roofs are the more common ones with a smooth surface and solid color. Mine has metal shingles designed to closely resemble traditional tar shingles. So their surface is not as smooth. The installers say they don't have a (I think the word they used was 'bolt' or something) that would properly attach the panel leg to the beam on the inside of the roof. Something about it would slip due to the nonsmooth shingle surface and that rainwater would leak through. So do you know what kind of bolt they should look for? They claim they've asked around and don't know anyone who has this. The roofing company is Erie Construction of Toledo, OH. The solar company is Missouri Sun Solar. I'm sorry I don’t know the brand name of the roof.

Hello! Let me paint the picture as best as I can - I have no pictures. House is a ranch, 1 layer of shingles on it now, no issues - they're just old. It's about that time :) Probably get another year or two out of the shingles before they start to curl, and all the neighbors have pretty architectural shingles and are all updated so why not me? It's all tongue and groove wood, no plywood - looks gorgeous from the attic underneath it. Got a couple estimates so far, but my question has to do with differing opinions between these guys as far as ventilation in the attic after the layover. The house is essentially a sort of "T" shape, and is 70 years old - all stone, great shape, BUT - no soffets. I guess they just didn't do that back then. And there's nowhere to PUT them, so, we're soffetless. I've got a brand new attic fan installed before we bought it last year, it has a ridge vent running along the large length of the top, and 3 gable vents, located at the "X" spots below - House: . . X X -|----X One of these contractors is concerned that it might not ventilate properly with a second layer, and recommends a tear off and start from the wood. Otherwise, he says mold might grow up there. Another saw no issues but suggested that when he does it that he also install another ridge vent running perpendicular to the existing one on the short length of that "T" above to help it ventilate, but didn't think it would be much of an issue. I almost feel like the one contractor is just trying to sell me a tear off that I might not really need. I mean... I've got a brand new attic fan, ridge vent, and 3 gable vents and no indoor appliances vent to the attic. It would surprise me to find mold up there, if the old floor/ceiling joists up there were thicker than the old school 6" ones that they are I'd almost make it another room. Thoughts? Oh - roof is 20 squares. So we're not talking about a huge attic here. But I don't have the sq ft of it, sorry.
