Every lead starts as a public request — "anyone know a good roofer?" That's a different kind of buyer than someone clicking an ad. They want the work done, and they said so out loud.
When five contractors buy the same lead, the homeowner stops answering the phone by call three. On PorchLead, your call is the only one coming. Quote at your pace, not in a sprint.
If the name, number, or address can't be confirmed, the credit returns automatically. You never pay for a dead end, and you never have to argue with support to get made whole.
