Roof tile adhesive

Hi all. I've got a problem with pigeons messing on my new patio due to them sitting on the edge of my roof. I've bought some plastic deterrent strips and was wondering the best adhesive to use to stick them to my roof tiles. It's an 80's house and I think the tiles is called concreloc. Thanks in advance

 

Hi. I've seen these but I need to put it on my roof which isn't flat that's why I've gone for the deterrent strips. I will see how they go and if not prob get an owl or hawk but will have the issue of not havin a flat roof. Any suggestions on fixing the strips and or fixing a owl on a slipped roof. Thanks

 

Ok thanks. Going to get one aswell cos they do me head in lol. I am also going to put the strips down as an extra. Any idea on adhesive. Thanks
