They were led down peacefully at 1220 GMT on Wednesday, two days after a similar protest at Heathrow, where banners were draped over an aeroplane.
Calls for inquiry
It is thought the group entered Parliament using visitors' passes and gained access to the roof through a fire escape.
The breach raised concerns about security at the landmark building, with some MPs calling for an inquiry into how the five had entered an area which was supposedly out of bounds.
The Metropolitan Police confirmed that the man arrested by officers was "a current Parliamentary passholder who has worked for members of both Houses" - a reference to the Commons and the Lords.
He is to be interviewed at a police station in central London under the Serious and Organised Crime Police Act, the force added in a statement.
No further of the man's identity were given.
