After an ice storm the phone beats the office, and a missed call is somebody else's roof
Demand here arrives in bursts around weather, and the constraint in those bursts is never marketing, it is who answers.
Ice and wind events put a county's worth of worried homeowners on the phone inside forty eight hours. The contractor who answers gets the work, and the one who returns calls on Thursday gets the leftovers.
Pull the phone records after the next event and count the unanswered calls. Almost nobody does this, and the number is usually the largest single leak in the business.
Build the overflow plan before the weather, not during it. Somebody on backup, a script for the office manager, and a clear rule about what gets promised while the ice is still on the roof.
After hours calls need a real path. An answering service is fine if it is briefed properly and takes an address, a roof age and a callback number. An answering service that says somebody will be in touch is a delay dressed up as coverage.
Speed matters most on the emergency calls and matters more than most contractors think on the ordinary ones. The first company to speak to a homeowner has an advantage that later, better companies have to overcome.
