In Connecticut, workers' comp is sold on the competitive private market, with rates built on loss costs filed by NCCI, the national rating bureau most states use. Carriers then apply their own multipliers on top, so comparing carriers genuinely matters for your premium.
For roofing and construction employers, the class code drives the rate more than anything else: roofing carries some of the highest workers' comp rates of any trade because of fall exposure. Wherever you operate, the experience modification rate is the biggest lever you control, and a cleaner claims history compounds into lower premiums year over year.
