Bird pulling Threads

[Ivan in Oz]

G'day Ppl,

Ihave recently got the Roof on the garage
And it is fully insulated in the Roof

BUT
The very edges of the Foil insulation joins, are peeling off; ever so slightly.
This is going to be made worse as birds [ The introduced Ferrel ones ]
are known around here to come in and keep pulling the loose ends.

I have seen them pulling the Alsynite roofs when Threads become exposed on the Top surface. But did not know about them coming in and attacking the underside.

What is good to stop this?
I have been told to use Airconditioning Duct Tape,
but thought this tends to Shrink at the extremes after time.

Any Ideas?
Photos if you want.

Ivan, as people say, a picture is worth a thousand words because I have no idea on what you mean

dunno about the roofing, but a few plastic snakes thrown on the roof scare off most birds.
