DNC (Do Not Call) List explained
DNC compliance falls under the FTC's Telemarketing Sales Rule, and it is not optional for any roofing company or vendor placing outbound sales calls. Violations tie into the same fine structure as broader TCPA and TSR violations, up to $1,500 per call, which turns a single afternoon of un-scrubbed dialing into a real financial exposure.
States layer additional rules on top of the federal floor. Texas SB 140 requires a $10,000 security bond as part of telemarketer registration, and Connecticut SB 1058 carries penalties up to $20,000 per violation while narrowing calling hours further, to 9am to 8pm local time.
There is a practical data-quality angle worth knowing too: roughly 30% to 40% of purchased lead-list numbers are dead or wrong, per research on purchased dial lists. That matters directly if a roofing company or its canvassing team sources dial lists rather than relying purely on inbound or owned-channel outreach, since every list needs to be scrubbed against DNC before a single call goes out, not after.
Why it matters when you're buying
If you or a vendor calling on your behalf skip DNC scrubbing to save time, that is not a shortcut, it is a $1,500-per-call liability sitting on your business, since the fine applies per violation regardless of intent.
