For those of you doing commercial HVAC - what's been your #1 lead source this year?

Trying to learn from people actually doing it.

with storm season ramping up i figured id share what ive been working on the past few months. been knee deep in hail data with a couple roofing companies in tx and learned a few things that might help anyone gearing up for a busy spring.

most guys are working off the same vague hail maps which is exactly why every storm turns into 30 trucks fighting over the same 4 streets. the maps tell everyone the same thing at the same resolution.

started playing around with nexrad radar data (same source hail trace pulls from) and ended up putting together a system:

1. pull MESH data from nexrad radar. that's the actual hail core swath gridded to ~1km. cores are usually only a quarter-mile wide - which is why you keep finding pristine roofs in towns that "got hit."

2. overlay county appraisal + permit data. year built gives you the original roof age and permit history tells you if it's already been re-roofed. filter to roofs 15+ years since last reroof AND inside the verified hail impact-zone. way fewer dead doors.

3. be on doors within 24 hours.

the gap between roofers who do this and roofers who dont is honestly huge. ended up building a tool to automate it because pulling this stuff manually every storm gets old fast.

happy to share if useful

anyone else doing something similar or running a smarter system?
