I've been on the Houston and home improvement board due to the Houston storm. We had a lot in and around The Dominion. If you guys need a roofer in SA that you can talk to for opinions or general info, I'm happy to help fellow Ags...no obligation or BS. This site has a lot of pros that have guided me in my personal projects and I'm happy to do the same.

There is no roofing company that should still be so busy right now that they can't get a roof on in a timely fashion unless their crews are chasing storms and unavailable.
You also should have no issue with overdriven nails if their crew knows how to calibrate a cool nailer as needed....unless they have an inexperienced crew. Certainteed and The new GAF Timberline HDZ mitigates issues with missing nail lines.
As for poor installs, I've seen some crazy stuff....I've seen 3 layers of shingles. Homeowners never know until we get the old roof off which is why we take everything down to the decking. Every company should be doing that but they don't.
Also as for this:
"Williamson Roofing is not responsible for nails penetrating electrical, plumbing or hvac lines in the attic.
Do not use Williamson Roofing"
Before we condemn them, To comment on this, we need to understand that NONE of those items should be near your decking or roof line. If they are, then it is up to the trade to properly protect that line. If not, they are improperly installed and not to code. As such, many roofing companies release themselves of these liabilities as there is no way to know or verify other trades' mess ups From the crews standpoint. You simply can't always see that. That said, For me, as the Project Manager, I like to take a peek inside the attic to kind of check stuff out first and hopefully mitigate the risk.
