'''Roof and tunnel hacking''' is the unauthorized exploration of roof and [[utility tunnel]] spaces.<ref>{{cite book |title=Access All Areas: A User's Guide to the Art of Urban Exploration |year=2005 |page=223 |author=[[Ninjalicious]] |publisher=Infilpress |isbn=9780973778700 |url=https://books.google.com/books?id=JhJjAAAAMAAJ&q=%22roof+and+tunnel+hacking%22 |access-date=29 August 2022}}</ref> The term carries a strong collegiate connotation, stemming from its use at [[MIT]] and at the [[U.S. Naval Academy]],{{cn|reason=Need a [[WP:RS]] reference for this term being used at the U.S. Naval Academy|date=September 2022}} where the practice has a long history. It is a form of [[urban exploration]]. 

Some participants use it as a means of carrying out [[college pranks|collegiate pranks]], by hanging banners from high places or, in one notable example from [[MIT]], placing a life-size model police car on top of a university building.<ref>{{cite web | url = http://hacks.mit.edu/Hacks/by_year/1994/cp_car/cp_car.html | title = CP Car on the Great Dome | accessdate = 23 August 2010}}</ref>  Others are interested in exploring inaccessible and seldom-seen places; that such exploration is unauthorized is often part of the thrill. Roofers, in particular, may be interested in the skyline views from the highest points on a campus.

On August 1, 2016, [[Red Bull TV]] launched the documentary series ''[[URBEX – Enter At Your Own Risk]]'', which also chronicles roof and tunnel hacking.
