Roof Types for Multiple Buildings

[ShawnHayes]

I read the article in the knowledge base about multiple buildings with varying roof types but I'm running into a problem. One of my roof types is on a garage and it's a gambrel roof. When building the roof I had to choose the option "ignore 2nd floor" so that the 2nd floor was basically the attic. Now the roof on the house is following the same pattern and I'm not sure how to change it. Any help is appreciated.
