What should I consider when choosing top structure shed fabrication services and tarpaulin for industrial or outdoor use?

Did you use any kind of drainage layer under your green roof, or just soil straight on the membrane? I’ve seen folks skip that step and wind up with soggy surprises.

I actually went with a gravel drainage layer before adding soil, mostly because I’d heard too many stories like yours. Even with that, the weight after a heavy rain was more than I expected. Curious if anyone’s had luck with those lightweight soil mixes - are they really worth the extra cost, or do they just dry out too fast? Also, when picking tarps for outdoor stuff, does UV resistance make a big difference long-term?

I went back and forth on the lightweight soil thing for ages. Ended up trying a bag of it on one section of my shed roof as a test. It was noticeably lighter, which helped with my peace of mind (my shed isn’t exactly Fort Knox), but I did have to water it more often than the regular stuff. The plants seemed happy enough, but I could see how in a hot summer it might dry out too quick unless you’re on top of it. If you’re somewhere that gets a lot of rain, maybe not such a big deal, but here in the Midwest we get these weird dry spells and I had to drag the hose up there more than I’d like.

On tarps - UV resistance is one of those things I didn’t think mattered until I saw what happened to my first cheap blue tarp after just one summer. It basically turned into confetti. The next time around, I spent a bit more for one labeled “UV stabilized” and it’s lasted three seasons so far. Not perfect, but way less hassle replacing it every year. If you’re covering something you care about or don’t want to mess with constant replacements, I’d say it’s worth the extra few bucks.

One thing I wish I’d done differently: when picking the shed company, I focused too much on price and not enough on whether they’d actually anchor it properly for wind. Had to go back and reinforce it myself after a storm nearly took the whole thing into the neighbor’s yard. If you’re looking at fabrication services, maybe double-check how they handle anchoring and drainage - those seem to be the weak spots from what I’ve seen.

Anyway, hope that helps someone avoid my rookie mistakes.

I get the hype around UV-resistant tarps, but honestly, I’ve had some “UV” ones still shred after a year or two. Maybe it’s our crazy wind more than the sun, but I’m not convinced it’s always worth the higher price tag. Sometimes I just double up on the cheap ones and call it a day… less stress if they get trashed. As for lightweight soil, I actually found it a pain to keep moist, especially on sloped roofs. Went back to regular mix with a bit of perlite and haven’t looked back.

I hear you on the UV tarps. The marketing makes it sound like they’ll last forever, but in my experience, wind and sharp edges chew them up faster than the sun ever does. I’ve had “UV-resistant” ones that looked like Swiss cheese after a couple of stormy seasons. At this point, I’m convinced the real enemy is the wind, not the sun. I’ve also doubled up on the cheap tarps - less heartbreak when they inevitably tear, and you’re not out a chunk of change. Plus, if you’re covering odd shapes or rough lumber, the pricier ones don’t seem to hold up much better.

When it comes to shed fabrication, I’ve learned the hard way that you get what you pay for, but only up to a point. I’ve had crews promise “industrial-grade” everything, but if they cut corners on the frame or the anchors, it doesn’t matter how fancy the tarp is. If you’re in a windy spot, make sure whoever’s building it knows how to brace things properly. I’ve seen sheds literally take flight because someone skimped on the tie-downs. Not fun.

About lightweight soil - totally agree. Tried it once for a green roof project and spent more time watering than anything else. It just dries out too fast, especially if there’s any slope. Regular mix with some perlite or even a bit of compost seems to hold moisture better and doesn’t blow away as easily.

One thing I’d add: if you’re using tarps for long-term coverage, check the grommets and seams before you buy. I’ve had some “heavy-duty” ones where the grommets ripped out after a week. Sometimes the cheap ones actually have better reinforcement, weirdly enough.

At the end of the day, I’d rather replace a cheap tarp every year than baby an expensive one and still end up patching holes. Just my two cents.

Wind is the real troublemaker, no doubt. I’ve watched a “heavy-duty” tarp get shredded in one afternoon when a storm rolled through - meanwhile, the cheap blue one next to it just flapped around and survived. As for shed builds, I’ve had contractors swear their anchors were solid, only to find the whole thing leaning after the first nor’easter. Now I double-check every anchor and add extra bracing myself. Sometimes you really do have to trust but verify...
