Help needed with LARGE phalaenopsis- repotting?

[lisa1996]

I have a large Phalaeonopsis. The leaves themselves are about 8 inches tall and all through-out the leaves roots are growing. Is this a sign that I need to repot? Is there anything that can be done to prevent the roots from growing through the leaves so profusely? It makes it difficult to handle. Also the leaves are so tall that they fall over. I stake them but it doesn't help much. The plant is very healthy -constantly in bloom or growing new leaves. I'm trying to attach a pic, but I'm not sure if it will come through. I'm new to this site but not to orchid growing. THANKS!
