Mosaicking raster files by counting them up

I've created multiple binary viewsheds which I want to combine by adding them up. Problem is that they have different extends, so they don't have a common intersection. Mosaicking doesn't count/add up the values. 'Weighted sum' /'Map algebra' only works for the intersection. Is there some way to solve this?
