Along Western Avenue the eaves grow their winter jewelry — icicles, then a thaw, then a night that freezes the whole street solid again. That let-go-and-lock-up rhythm is what makes Westfield snow work its own discipline, and JP Carroll Roofing takes it on: plowing drives, clearing walks, breaking up the glaze that forms wherever meltwater runs and stops. Reaching bare surface before the next cold snap is the difference between an easy February and a treacherous one. The best sign of a job done is an unremarkable morning — everyone leaves on time and nobody slides. That is what the truck goes out for.
