Emergency & storm work
Leaks. Slipped tiles. Storm damage. Flat roof failure.
The customer is on their phone within minutes of noticing the problem. They're searching 'emergency roof repair [borough]' or 'roofer near me' and calling whoever comes up first in the map pack. The three-box map result matters here far more than page-one organic results. If you're not in it for the borough where the roof is, that call goes to someone else. This is where storm spikes play out. Rank before the storm and you get the calls during it.
