cap ?
A tower mill is a type of vertical windmill consisting of a brick or stone tower, on which sits a wooden 'cap' or roof, which can rotate to bring the sails into the wind.

No he didn't put a windmill, but I think he added solar panels on the roof.
you jump up on the windmill and it will spin it clockwise. keep doing it until the little dome on the roof is open.
Another name for a windmill is the wind turbine
Go inside the mill, on the second floor, and hang from the rope that unlocks the mill gears. Then go outside and climb on the windmill arms to turn them counter-clockwise. This will open the roof dome. (see related question)
There is no key. Release the gear lock, then go outside and climb on the windmill arms, turning them counter-clockwise. This will open the roof dome.
You click and spin the windmill blades, and then when all three are spinning, the light will turn on in the house, and you will pull the right side of the roof up, and the PLAY button will be there! :)
There isn't an amount, you have to jump on them until the roof opens up.
DAVE :)
Go inside the mill and pull on the rope that releases the gear lock. Now the arms of the windmill will turn. Go counterclockwise and watch the roof dome.
