Exposed nails on last row of shingles for sloped flat roof.

[Alfredo Corral]

Hiw do I cover nail heads from last row of shingles?  I started from bottom to top of aloped flat roof. Nails are above drip edge.

I would try and fit a cap shingle sort of side saddle. Nailed on top and on vertical beam.  If that does not work out I would dab a bit of roofing tar on each nail and call it a day.

HERE that flat of roof doesn’t last long.  They make rolled roofing that works better on that slope.

What is the purpose of that structure?  Might want to rethink the next one you build. More slope and the other half for roof reasons OR metal roof
