Hello
Please can someone help with some advice?
our house has a standard tile roof, where the tiles are supported by sloping wooden rafters spaced maybe 18" apart, and there's a layer of back mesh underneath the tiles ("felt"). The rafters run from the eaves up to the ridgeline of the roof.
At some point in the past, a roof extension at 90 degrees to the ridgeline means another section of roof projecting out of the back of the house. This means that, if you go into our loft, there's the main original loft with another newer section of loft partitioned off from the original by a section of now-enclosed "old" roof rafters.
This partitioning piece of roof work has no tiles on it any more (because it's now "inside" the roof) and the felt has been taken off. What is still in place, however, is the now-redundant rafters. If I could saw one or two of them out, then I could easily board from the original loft area to the new area. Trouble is, I have no knowledge of roofs (as you might have noticed) and I fear that one sawcut and the whole lot will collapse into tens of thousands of poundsworth of repair.
1) How many rafters can I cut out without worrying?
2) Do I need to cut only one or two out at the most and then buttress the resultant gap with extra wood of some sort?
Thanks
