Every unanswered call goes straight to the next name on the same shortlist
Roofing buyers call three companies in a row, and the order is decided by who picks up first.
Pull the missed call report from your phone system and read it by hour and day. Most offices are surprised by two things: how many calls are missed, and how tightly they cluster at the times crews are busiest.
Demand here spikes on a schedule you can anticipate. The morning after a hard freeze, the first warm rain after a cold stretch, the day after a wind event. Have an overflow plan for those days, whether that is a briefed answering service using your intake questions or a rotation that pulls somebody off another task.
An automatic text back within a minute of a missed call recovers a meaningful share of them. It costs almost nothing and it works because the homeowner is still holding the phone.
Voicemail is not an intake system. By the time somebody listens to it, two competitors have already offered a time.
