My house was hit by a tree during Sandy. A few rafters was broken/cracked. The roof contractor had come and replaced a few broken rafters. However, I found there are still 3 rafters with cracks, some about 2 to 3 feet long, not being replaced or reinforced. I wonder if I should insist to have the roof company replace them. In the attacked picture "cracks.jpg", you can clearly see some of the cracks. Another issue I have is that the last rafter that is next to the back side of the house was broken. The contractor only replaced half of the rafter, not the whole piece, as see in the picture "joint.jpg". Does it matter?
