Score every home by roof age, exterior material, and storm exposure. Gutters often pair with roof replacement — when you find one prospect you find the other.
Gutter replacement and installation overlaps significantly with roofing — many gutter contractors are roofing companies running gutters as an add-on or vice versa. CurbSight's roofing signals (year_built, hail exposure, storm history) apply directly. As a bonus, properties with documented hail damage that are getting a roof replacement are also typically getting new gutters — that's a paired lead.
