Metal over shingles

Thanks for helping out. I want to put metal over shingle. Two contractors say to put directly on shingles, 3rd one says to put on 1x4 slats. The 3rd one is the most expensive. What should I do and why?

Metal Roof

Follow the metal roofing manufacturer's installation instructions to maintain the warranty.

I agree with Ken, but all the guys I use specify the 1x slats along the edge and across the roof. It gives more air circulation, a flat installation substrate, and it won't grind into the back of the metal causing a rust spot.
