Roof checkups saved me big bucks - anyone else?

I’ve had similar issues with raccoons, and honestly, I think people underestimate just how persistent they can be. Screws with washers are definitely a step up from staples - staples just don’t have the holding power once those critters start tugging. I’ve actually gone a bit further in some spots and used metal flashing over the hardware cloth, especially around known entry points. It’s not always necessary everywhere, but in high-traffic areas or spots where I’ve seen repeated attempts, it’s made a difference. It does add to the labor and cost, though, so I wouldn’t call it a blanket solution.

As for motion-activated deterrents, mixed results here too. The lights didn’t faze them much, but a neighbor swears by the motion-activated sprinklers. I haven’t tried those myself - seems like it could be a hassle on the roof, especially with wiring and water lines. In my experience, physical barriers are still the most reliable, even if they take more effort upfront. Raccoons are clever, but they’re not getting through steel and screws... at least not yet.

Metal flashing over hardware cloth is a solid move, especially in those high-risk spots. I’ve seen raccoons peel back staples and even some screws if the wood’s soft or rotted, so using washers definitely helps distribute the force. One thing I’ve noticed during inspections - sometimes folks miss gaps at roof-wall intersections or around vent pipes, and that’s where critters get clever. Motion-activated sprinklers sound interesting, but yeah, running water lines up there seems like more trouble than it’s worth. Physical barriers just seem to hold up better long-term, even if they’re a pain to install.

You nailed it with the physical barriers. I’ve tried a few “clever” deterrents, but nothing beats just making it impossible for critters to get in. It’s a pain up front, but way less hassle than patching holes every spring. Those roof-wall gaps are sneaky - easy to miss if you’re not looking for them.

Totally agree, those little gaps are like secret doors for squirrels. I thought I’d sealed everything up, but last fall I found a spot behind the gutter where something had chewed through the mesh. Honestly, I wonder if there’s a way to make those barriers more eco-friendly? The metal stuff works, but it’s not exactly green. Anyone tried recycled materials or something less industrial-looking? I’m always torn between durability and sustainability...

I get wanting something greener, but honestly, I haven’t found anything that holds up to squirrels and raccoons like metal does. Tried some recycled plastic mesh a couple years back - looked better, but the critters chewed right through it in a month. Maybe there’s a middle ground, but for now, I’d rather patch once with metal than keep replacing stuff. If anyone’s found a tough, eco-friendly option that actually works, I’d be interested... but I’m skeptical.
