Woven tarps definitely hold up better in rough weather, especially if you’re dealing with a lot of wind or sun exposure. One thing I’d add—if you’re covering anything with sharp corners or edges, it’s worth using some kind of padding underneath the tarp. Even the heavy-duty ones can wear through if they’re rubbing on metal or wood. I’ve also found that grommet spacing matters more than you’d think; closer grommets make it easier to tie things down tight and avoid flapping, which helps the tarp last longer. Custom sizing is great, but don’t forget to check the UV rating—some “heavy-duty” tarps still break down fast if they’re not UV-treated.
- Padding under the tarp is a game-changer, especially if you’re covering something like a trailer or stacked lumber. I learned that the hard way—lost a corner to wind rub last winter.
- Grommet spacing really does matter. I used a tarp with wide grommet gaps once and it flapped itself to shreds in a month. Closer spacing lets you cinch everything down tight.
- UV rating is huge if you’re in a sunny spot. Some tarps look tough but get brittle fast—my last “heavy-duty” one basically disintegrated after one summer in Texas.
- For shed structures, I’d add: check the welds and frame thickness. I’ve seen some cheaper prefab sheds with joints that rust out quick or frames that twist in heavy wind.
- If you can, go for custom sizing. It’s more up front, but you won’t be fighting with extra material or weird gaps.
- One thing I sometimes skip but always regret: double-checking the warranty and what it actually covers. Some only cover stitching, not UV breakdown or grommet pullout.
It’s all about matching the tarp and structure to your weather and what you’re covering. Sometimes spending a bit more up front saves you from replacing stuff every season...
I get the logic behind custom sizing, but man, the price jump can be rough if you’re just covering firewood or a mower. Has anyone found a decent off-the-shelf tarp that actually holds up for more than a season? I’m always skeptical of the “heavy-duty” label—seems like it means nothing half the time.

That’s not just you. “Heavy-duty” on a tarp is like “gourmet” on potato chips—sometimes it’s just there for show. I’ve poked around more tarps than I care to admit (occupational hazard) and honestly, most big box store tarps labeled “heavy-duty” are still pretty thin once you get them out in weather for a season. UV exposure especially just eats through them.
If you’re covering firewood or a mower, I’d look at woven polyethylene tarps with at least 12 mil thickness. Anything less is basically single-season disposable, in my experience. The silver or green ones at Harbor Freight or Home Depot are usually about 8-10 mil, and they’ll get brittle by spring if you’re in a sunny spot. If you can find one that lists both the weight (like 8 oz/sq yd) and the thickness, that’s a good sign—they’re actually telling you what it’s made of.
One thing people overlook: the grommets. Cheap tarps have grommets that rip out as soon as there’s any wind. I’ve seen folks reinforce them with duct tape or even old garden hose pieces when they start to tear, but that only buys you a little time.
Custom sizing does sting on price, but sometimes local farm supply stores carry “contractor-grade” tarps that are overbuilt because they’re meant for hauling debris or covering machinery—usually black or brown instead of the classic blue. Those last longer than anything from the camping aisle.
If you’re somewhere with lots of sun and rain cycles, it might be worth trying canvas tarps instead of poly. They breathe a bit better and don’t shred as fast, though they’re heavier and not fully waterproof (more water-resistant). Not perfect for everything, but decent for firewood.
I wouldn’t trust anything labeled “all-weather” unless you can feel how thick it is before buying...or unless someone around here swears by a brand I haven’t tried yet. The marketing terms really don’t mean much—look for those numbers on the packaging if they bother to include them.
And yeah, if you find one that lasts two seasons without turning into confetti, let me know...I’ll buy stock in that company.
You nailed it about the marketing fluff—“heavy-duty” is basically meaningless unless there are specs to back it up. I’ve seen too many tarps fall apart after a single season, especially in direct sun. The tip about looking for mil thickness and weight is spot on. Honestly, I’ve had better luck with contractor-grade tarps from ag supply stores too, even if they’re pricier upfront. Grommets are the weak link for sure...I’ve reinforced them with scrap rubber before, but it’s just a temporary fix. If you get more than two years out of any poly tarp, you’re ahead of the curve.
