Idaho License question

In Idaho, I’ve been informed BY THE STATE that there is no roofing license available. We have mandatory contractor registration but the only license you can get are for public works projects. Recently the owner of another roofing company (competition) informed me that if I didn’t have a license then my opinion wasn’t valid in terms of his improper installation techniques. Long story about how I even got involved in this but I did & now I’m paying for it. My question is: Is he right or the State? Is there a license available in Idaho? Have I missed it after all this time? It was never required for the formation of my corporation so what gives? Thanks in advance!!

i would contact the state. if they say no there isnt one…try to get it in writing with a state letter head.
