Stopping cats pooing on the roof

[mnahmnah]

Hi

I have searched and searched online and every product I look at has mixed reviews, so I’m after some fail-safe methods please!

We have a small sloped roof on an extension at the back of our house, directly above our patio doors to the garden. Cats keep pooing all over it. It’s disgusting. When the weather is nice, you smell it as soon as you go out there and I have to start the clean-up again. Sometimes it’s rolled down into the garden too. Two small children, so really not good for them.

What actually works to keep the cats off a roof like this please?

Jeys powder granules. They hate the smell and lasts longer than the liquid.

Great! Thanks. How often do you need to reapply them?

I can only see their fresh bin or outdoor cleaner on Amazon...

I'd be doing it every few days for a while, I'd also consider pouring some oil on the roof too, they hate getting greasy. You just need to make your roof the least easy option for shitting until they change their habits.
Once they stop, it's a matter of keeping a weather eye on the situation.

That's it,
