What is a bid vs. an estimate in roofing repairs?

Bid: An offer (at a certain price) for something, especially at an auction.

Estimate: To roughly calculate or judge the value, number, quantity, or extent of something.

Getting a roof properly repaired is never a “bidding” situation. That results in sacrificing long-term quality for the short-term price. A roofing claim is always based on an estimate, as roofers and adjusters do not have x-ray vision.
