Flat Roof leaks

I have a few rental properties that have flat roofs. I've had recurring leaks on a house that has been coated with that thin black stuff and patched with Henry's Wet Patch. I spoke to someone in the neighborhood who was doing a repair on an identical problem. He said he uses 4 rows of Asphalt Paper(?) to seal the area near the edge where the water travels to. I decided to give it a try. We overlapped the rows by a couple of inches and sealed the edges with wet patch. The first row near the roof's edge was was pulled up about 8 inches to go on the ridge of the roof and nailed down then sealed with the wet patch. I'm not real confident about this repair.
Please tell me what is the best way to keep a flat roof leak proof for a relatively long time. Also, what is the proper way to lay and seal the roll on asphalt. Do you coat the bottom with anything or just the edges? Was it ok that we used nails on the ridge?

4 ply

Sound like your neigboor had a 4 ply roof install.
If your flat roof look decend i would go for a 2 ply roof.
Also have 2 ply flashing install one with felt the other ply with fabric.
As for the top coat it depends on location.
If your in a windy sector i would have 3/8 gravel applied on it
i would get a roofing company to give an estimate on it.
there an old saying Pay me now or pay me later,.
Better fix it when small than wait it a major one.
