I have roofed a few houses in my day ..and all of them but the last one ,,, I used a air nailer
One thing I never considered doing is putting roofing over the top of roofing .
So, beings my roof is close to 20 years old and still laying flat and not curled up or any breaking tabs off
What is your advice on leaving the old on and roofing over it?

My reason for leaving the old on is for two reasons . less cost to install a new roof and more insulation
