After gutting a 100+ year old house, we found that the ceiling joists supporting the dormer are 2x4's, and many have sagged over the years, and a few have cracked and broke at the ends.
I wanted to get some opinions on what would be the ideal way to repair this.
One side is about a 11.5' span...
Looking for cost estimates: I'm adding a third floor master suite and want to build 3 dormers to open up the attic. One is gabled (8 ft x 15 ft), one is a shed (4 ft x 10 ft) and one is doghouse (6 ft x 6 ft).
