Said It Here

Should I trust the contractor who disagrees with everyone else?

When a lone contractor is willing to use a method that an overwhelming majority refuses—such as a specific skylight mount or equipment pairing—homeowners are left guessing whether the dissent reflects a real technical barrier or just an avoidance of extra work. This conflict stops people from knowing which recommendation to trust, leaving them paralyzed between missing out on a preferred setup or risking system efficiency.

“I have spoken to 3 contractors so far for comparative pricing with the first 2 planning on doing metal roofing. When I spoke with the third contractor he was adamant that I must do rubber roofing as he said it was best for flat or low-slope roofs where water might otherwise pool.”source ↗

“After googling comparisons, I'm leaning towards rubber roofing. But I wanted to come here for some opinions on whether the type roof I pick will make a huge difference?”source ↗

“I’ve had three contractors look at it and they’ve each proposed different solutions, ordered from cheapest to most expensive: torch-down patch ($500); shingles over the existing roof with step flashing ($1500); and a full replacement with the same type of rolled roofing “done correctly” ($2300).”source ↗

“I’m completely new to this so I have no idea which to choose, so would appreciate any advice here.”source ↗

“I’ve had four roofers out to look at it and give a quote.”source ↗

“The first three recommended tearing up the roof and adding pitching.”source ↗

“The fourth said there is already a pitch, he believes there’s decay under the middle of the pitch causing an area that sags. But he wouldn’t recommend pitching it anymore, just fixing the pitch.”source ↗

“Not sure what to believe.”source ↗

“I've gotten quotes/opinions from several roofing contractors, and almost all of them won't do a curb-mounted skylight on this pitch — they only want to do deck-mount. I found one contractor who's willing to do curb-mount.”source ↗

“Given that the overwhelming majority are steering me toward deck-mount, should I just go with that instead of pushing for curb-mount with the one contractor willing to do it? Is there a real technical reason to avoid curb-mount on a steep pitch like this, or are they just avoiding the extra work?”source ↗

“instead i spent the last couple of weeks comparing quotes, equipment options, and installation details. every contractor seemed to recommend something slightly different, which made the process more confusing than i expected.”source ↗

“This is my first home and so I don't know the in's and out's of what needs to be done, correctly, and efficiently. 3 out of 4 quotes told me I should get indoor waterproofing (one of them was a national company and way over-priced so I'm not going to include them).
