Suzi and I spent her day off putting the  underlayment on the roof.

We used a product by Grace called tri-flex instead of tar paper. 

It was weird putting nails in the underlayment instead of staples. 

The product was TONS lighter than tar paper making the job as a whole alot easier. 

We did have alot of over lap (20in) since our roof has so little slope. Causing us to use more underlayment than I originally calculated.  But I only needed 1 row of paper at the top so I got tar paper for that.

We have the shingles now and are ready to go...
