Doing a small roofing project, first time for me. I have a small outbuilding with a good pitched roof but it was built by goofuses. For one thing the PORCH roof (about 9x30 ft) is almost flat and they put shingles on it. So the decking is starting to rot underneath, near the gutter.
I was advised by a 30-yr pro to tear it off, fix the rot, and put down stuff that looks like gravel covered shingle but comes in a self stick roll. CertainTeed Flintastic SA is what I got. He said to put tar paper underneath. So I have all that and now I'm looking at instructions from CertainTeed. They recommend "Certainteed Nail Base" on the bottom and then a "mid-ply" layer. Where it meets the higher sloped roof, they recommend using a mastic (theirs of course) to glue down an extra layer of Mid-Ply at the crease. Looks like a type of tarpaper reinforced with polyester or some such. My store does not even carry this.

Questions:
1. Is standard tarpaper (I got the heavy stuff, 32 lb or something) OK for the bottom layer?
2. Do I need the MidPly? Will it make the roof last longer or what? Can I use standard tarpaper for flashing
at that transition? They also show an extra piece at the bottom edge of the roof.
Hoping to get this done this weekend, it may be the last time it's cool till fall.
Any advice greatly appreciated.
