Metal flashing’s not foolproof, but it’s way better than patching with foam or mesh.
I get where you’re coming from, but I’ve actually had decent luck with heavy-duty mesh in a couple spots where flashing just wasn’t practical (weird angles, old chimney base, that kind of thing). It’s not as bulletproof as metal, but if you double up and use the right fasteners, it can hold up for a few seasons—especially if you’re on a tight budget. I do agree that foam is pretty much useless for anything persistent, though. Critters chew right through it.
Insurance is a whole other headache. Last year, they just wanted photos after a hailstorm. I tried to be thorough, but I’m no expert—missed a cracked vent boot that turned into a leak months later. If you’re doing your own checks, I’d say look at all the weird corners and under the eaves, not just the obvious spots. Sometimes the “quick fix” is all you can afford, but it’s worth keeping an eye out for stuff that might get worse over time.
I’ve always wondered if mesh actually holds up long-term, especially with squirrels or raccoons around. Have you ever had critters get through your mesh patches, or does doubling up really stop them? I’ve only used metal so far, but there are spots where it’s just not practical, like you said. Also, how do you handle those weird corners when you’re checking for leaks? I always feel like I’m missing something in the valleys or behind the gutters.
- Had squirrels chew through cheap mesh once. Upgraded to hardware cloth, doubled up in weak spots—no new holes so far.

Same here. I use a hose to check those spots—run water and watch inside for drips.“I always feel like I’m missing something in the valleys or behind the gutters.”
- Corners are a pain. I jam a flashlight up there and look for daylight or stains. Not perfect, but better than nothing.
- Metal’s great but yeah, sometimes it just won’t fit. Mesh is a compromise, but you gotta check it every season.
I get the appeal of hardware cloth—definitely tougher than standard mesh. But honestly, I’ve had critters find their way in even with doubled-up metal in some spots. It’s wild how persistent squirrels can be. What’s worked better for me is going with a living roof—sedum mats over a waterproof membrane. Not everyone’s cup of tea, but it’s kept the animals out, and it insulates pretty well. Downside: more upfront work and you gotta watch drainage, especially in corners. Still, I don’t miss patching up chewed holes every spring.
Living roofs are definitely cool—love the insulation factor—but yeah, that drainage issue can sneak up on you. I’ve seen a few folks get water pooling in one corner and suddenly there’s a leak right through the ceiling. Personally, I still stick with hardware cloth in combo with flashing, but I add a bead of sealant at the seams. Not perfect, but it slows down the critters. Curious if your sedum mats ever get heavy after a big rain? That weight can stress older rafters if you’re not careful...
