I need to create a rendering of the interior of a residential home. These renderings need to be done without the roof being visible from a birds eye view. To capture the lighting quality desired I need the interior space to render as if the roof were present.

 Also, I will be placing lights on the interior hosted to a ceiling.  Same question.... is there a way to capture the lighting quality without the ceiling physically being in the rendering.

Have you tried setting this ceiling to transparent for this rendering?

I don't see why not you can do that. All you have to do is to hide the element (HH) in your case the roof and the ceiling. you should be able the render it using a interior: artificial only or sun and artificial under lighting scheme. You might need to play around with your sun settings to get your desired set up so (preferably just before night time) so it won't be to bright so that way your interior will show up with the right contrast. The only problem I see is that you lighting fixtures...do you want them to show up on your rendering? if you don't want to... I'll suggest you use the "studio light" fixture... it's like an omni lights that shoots rays of light everywhere w/o the hardware showing up in your render image.

These suggestions are in the right direction but not quite there.

I am doing this rendering for a popular shading coming. i need to do one rendering with the shades up and one with the shades down. Both of these renderings need to be done from an over head view. Basically, I need to have the roof casting shadows but I would like the roof to being invisible. Setting the roof material to transparent would not cast the desired shadows.

The only thing I can think of is to set up a scene that is using all artificial light, even and artificial light that represents the sun to fake the render. 

 Let me know what you guys think. Thanks again.

I don't think that you can do it directly.  You can place the camera in the view and stretch the crop region, but it will distort horribly.  The only suggestion that I can think of is to raise your ceiling level so that you can place the camera in a realistic position to see the floor and walls so that they don't distort.  The ceiling will need to be fairly high and you may need to adjust the brightness of your lights accordingly.

Mental Ray doesn't have the same ability that Accurender had to use another view for the shading...  I'd imagine you might have to do some composite imaging and merge together in photoshop or use 3DS Max or similar...
