Here's a pic of my attic:
Counting the rafters/joists from left to right, number them #1, #2, #3, #4, #5.
I'm going to cut #3 & #4 (both rafters/joists) to install a 44 1/4" wide (rough opening) skylight. I need to double-up joists & rafters #2 and #5
My questions are:
1. Can I double-up rafter #2 by adding a new one to the RIGHT of it? As you can see, it would not be able to be a "full length" rafter like the existing #2 is because joist #2 is "in the way"....so the rafter would have to "rest" on joist #2, is that ok? Or do I NEED to double-up to the left of the existing rafter with a full-length 2x6?
2. I need to double-up joist #2 to the LEFT of it, otherwise my rough opening for the skylight will be compromised. How can I double-up joist #2 to its left? Can I add 2 2x6's, one that won't be full length (because the rafter is in the way) and then one that WOULD be full length (because it would be to the left of rafter #2)?
Hope I described it well enough for you to picture it and understand my dilemma. Let me know if you need clarification or more pictures. Thanks!
