The leak call is qualified by address before it is qualified by budget
Jurisdiction is the first question in this metro and asking it late wastes an estimator's whole afternoon.
The District, suburban Maryland and Northern Virginia license and permit separately, and specifics are worth confirming with each jurisdiction. Whatever your coverage is, the person answering the phone needs to establish which side of a line the property sits on inside the first minute.
Write it into the script as a natural question rather than a gate. Asking for the property address early is normal, useful and lets you say quickly whether this is a job you can take. Everybody prefers a fast no to a slow one.
Then route by covering. A flat rowhouse roof and a pitched shingle roof often need different estimators, different equipment and different scheduling, and sorting that on the call prevents the survey where the wrong person shows up.
Track declines with a reason code. If a meaningful share of inquiries are being turned away for jurisdiction, that is a targeting and website problem showing up at the phone, and it will keep costing you until the source is fixed.
