You are missing a left bracket.

Table[MeijerG[{{1},{0.5}},{{1,1},{0,0.5}},z], {z,0,10}]

{0,0.211277,0.704558,1.02387,1.11416,1.00746,0.763094,
    0.443949,0.10587,-0.206721,-0.461986}

Plot[MeijerG[{{1},{0.5}},{{1,1},{0,0.5}},z],
    {z,0,10}];

FindRoot[
      MeijerG[{{1},{0.5}},{{1,1},{0,0.5}},z]==0,
      {z,#}]& /@ {.5,8}

{{z -> 0.538334}, {z -> 8.32402}}
