felt tiles

[woodman-46]

Hello,
I want to use felt tiles to cover the roof of a lean to shed I have built. I have already covered it with green "gritted" felt and wondered how to fix tiles to this.If I use this bituminy adhesive to fix the felt to the gritted surface I am worried the brushing action will dislodge the grit and make for an uneven surface. Any suggestions?
Also where can I buy these tiles and do they come in lengths of connected tiles or individual tiles? Strips would be preferable.

Thanks in advance

James

Wickes sell them as do others. I was going to use them, then saw the size of the job on my shed and used the green corrugated bitumn instead, £8 a sheet from b&q, then you need 30 or so fixings per sheet.
