i want to install a roof hatch on my flat roof which needs repair or replacing, but everytime i've asked for estimates with reroofing- their quote for the hatch installation is at least $750! or other roofers say they don't install them.
i'm wondering why its so high, am i missing something about hatch installation? i thought is involves cutting a hole, sistering roof joists/rafters and installing per manufacture instructions and proper flashing. am i insane to consider hiring a handyman to install before foaming or reroofing?
i figure the best time to install a hatch is during a major repair- ie foam roof or complete reroof.
