Venting to roof from bathroom in dormer

So i want to install a 3 way system in ceiling of bathroom. Since the bathroom sits in a dormer i have no attic access. my thought was to cut the opening in ceiling large enough that i can physically get into dormer to attach the exhaust duct to under side of cap on roof.
From unit to inside of ceiling in only about 2-3 . will i have any issues with any codes with this? Also a roofer wants to charge
$450 to install the duct cap to roof. is that reasonable ? thanks

That sounds like a good plan, get 2 more quotes, may from HVAC people, they will install the unit duct and cap, 450 sounds a little over the top.
