2015 IRC section R905.1.2 calls for it "in areas where there is a history of ice forming along the eves." But we don't know what code you go by. Where I live it is standard practice. But your contractors who are on the low end omit it...

I would do it on my house as cheap insurance. Google the above code, it details the requirements. At least 24" inside the interior walls. (Where heat loss from the house is in the closest proximity to the roof decking) This generally means 2 rows of ice and water along eves.

Someone told me as long as I have good venting and a cold attic I shouldn't need it. I'll put in on to be on the safe side, thanks...
