Hi all I would appreciate some advice about whether I can butt a galbe roof onto the side wall/roof of my house to 'attach/build in' another room on. The house external wall is western red cedar and the roof is colourbond steel. The ceiling is cathedral which means (if I have the term correct) there is no attic and not much room between the ceiling and steel roofing. There are beams under the roof holding up western red cedar ceiling planks and the beams are held up by 100x100 studs at each end of the house/room (so to speak). Is there any way I can build a new gable or any type of roof line to enable me to extend at right angles to the run of the beams? I hope the above makes sense. I can take photos if anyone prefers to view prior to commenting.Cheers & ta Donno
