Lay 5/8" or 3/4" plywood on the existing lattice and finish with 30 lb. felt, ice and water shield at the edges, and 30 year shingles.

I had it all done on this house for $4500 in labor about 10 years ago. The materials added another $2500. or so. It is 17 square. The roof is an 8 pitch which they walked.
