You go to the rooftop to reach the third spy. The only way to get to the rooftops on Balding Avenue is to use the grappling bowtie on the building just to the right of the Grease Monkey garage. You get the bowtie when you rescue the second spy. (see related questions)
Climb the building with the grapple bowtie and go to the Rooftops. Put on your chameleon suit because the tall building is guarded. It also has lasers to keep you from going straight to the antenna on top. Grapple over to the left, Dodge the guard, and go farther left to the red building. Climb up and grapple back to the right (there is a friendly agent there to suggest this). Then you can enter through the roof duct. (you should remove the bowtie when inside)
The connection to the Rooftops on Spy Island is directly above the Grease Monkey garage on Balding Avenue. You will need the Grappling Bowtie from the 2nd rescued spy in order to reach the rooftops.
