Can I listen to the calls an appointment setter makes for my roofing company?

Usually yes, but only if you ask for it in writing before the program starts, because not every company hands over its recordings. Recording outbound calls is standard practice, and some vendors keep the audio and send you nothing but the booked appointment. That recording is the only way to check how your company was described, what the homeowner or property manager actually agreed to, and why an inspection did not get walked. Recording laws vary by state and some require everyone on the call to consent, so a vendor should be able to explain how it handles that. Lead Engine books every appointment against a seven checkpoint standard, and call access is a fair thing to ask any vendor for.
