Rock and Roll!
— Roley's Catchphrase

Roley is a green road roller who loves to make up songs and frequently spins his eyes when he is excited. He is best friends with Bird.


Roley was the fifth machine to join Bob's team. Before he joined, Bob and the four machines were building a road using concrete. However, after they had finished, the road's surface was bumpy. Bob used his hand roller and the machines tried running over the concrete to flatten out the road, but it did not work. Luckily for them, Bird saw the situation and went to get his friend, Roley. Soon Roley arrived and and told the team that they needed some rock and roll. Bob replied that that they were fine from music, but Roley meant it as in flattening. Soon, he got to work, making the road's surface smooth and flat. After that, he joined the team and Bob said that he had machines who could do anything.


Roley is a heavy, cheerful machine who can get excited and loves to "rock and roll"! He's shown to be very musical and usually makes up songs and he even sings them during work. He spins his eyes when he's excited and is also fond of animals.


Roley is green with a silver bell-shaped mouth. His rollers were dark grey in the stop motion era but were changed to black when the show transitioned into CGI in the Ready, Steady Build! spin-off. He has an orange-yellow warning light on his cab.


Roley resembles a Zettelmeyer diesel road roller.


Original Series:



  • In 2003, Jolly Roger (Amusement Rides LTD) made him as a kiddie ride that says three different phrases, including: "Rock n Roll!", "Oh! That is really cool, Bob!", and Can we fix it? Yes we can!", and plays the Bob the Builder theme tune. Also, in 2004, Jolly Roger made him as another kiddie ride, but this time with a video screen (normally there's a windscreen on the front). There are 2 push buttons on his dashboard (video option, one push button if standard). One button says "Rock n Roll!", whilst the other button says "Oh! That is really cool, Bob!".
  • Roley's movement sound effect is simply his front roller moving over the ground. This effect is heard regardless of the surface he is on. This rolling sound wasn't used in the Ready, Steady, Build! series.
  • Roley is male in all dubs, but is female in the Swedish dub.
  • Like Lofty, he is voiced by female voice actresses in the US dub.
  • Roley appears to like rapping as seen in Roley's Weather Rap.
  • He was the first machine character to appear onscreen in the first episode of the Original Series, "Scoop Saves the Day" (Season 1).
  • In the UK dub, he speaks in an East End cockney accent.
  • Roley was the first vehicle that Farmer Percy Pickles had a ride on.
  • In the Finnish version, Roley is called "Rolle"
