Hi,
You can insert the main roof with the roof by perimeter tool. It will follow the shape of the perimeter walls of the house.
For the verandah roof, you can use the roof by picking points tool to manually insert.
You will want all the sides of the roof touching the house walls to be a gable roof shape.
Then you will want to select the roof>make all the outside arrows green by selecting them
Right click>properties>support & details tab>change the support height to lower below the main roof
