Made of heavy-duty canvas coated with polyester, these incredibly strong tarps will perform in a wide variety of uses thanks to the high-tenacity, knitted polyester mesh.
Then I also bought the biggest roofing metal screws - with the sealing rubber washers - inch and half.
So the first tarp I will have to screw into - so I'm going to just lay the tarp over the rafters - and then I'll use the extra length of 6 feet - to then create enough space hanging down - to hold the Rock Wool insulation.
So I can then tie off the ends and put in the insulation. And this will cover over the rafters also.
Then I cut cross beams lengthwise - so 9 feet long - I'll do two on a side so 4 in total.
So oh I forgot - when I have the tarp dangling before I put in the rock wool - so then I mark where to tape the tarp along the rafters. So then I cover BOTH sides of the tarp in Duct tape along the rafters.
THEN I put in the insulation. And so when I screw in the cross beams - it - wait a second - I should just NOT screw into the tarp.
Yeah the tarp will hang down. I put the insulation in to hold in the tarp. I then tie off the ends of the tarp around the framing. So then when I put the cross beams over - the screws as inch and half - will just go into the rafters.... Oh they HAVE to go through the tarp still.
Yeah - unless I got CLAMPS.
Oh Goodwill has CLAMPS - they should be real cheap!!
So I go buy a TON of clamps and then I CLAMP the tarp to the rafters - from the bottom side!!!
Then the tarp is just from the bottom - so that the screws of the cross beams go into the rafter WITHOUT going into the tarp. That's the ticket.....
So that saves that first tarp. So I gotta go to Goodwill to get a ton of clamps. Let's see FOUR - eight rafters....
Maybe three clamps per rafter? So 24 clamps.
It's a lot but worth it to maintain the water resistance repellent ability of the tarp....
Don't want water dripping through screw holes.
OK...
So now the crossbeams are screwed in - over the insulation and the first tarp that is clamped in.
THEN I put the 2nd level of insulation going parallel with the crossbeams. This stops any "holes" in the insulation (such holes create ice dams)...
THEN I put the 2nd tarp over the whole top of it all. And I secure the grommets on the second tarp.
OK this Amazon link is the CLOSEST to what I bought - I think it's the SAME product
So it's the same size - 6 inch long with 4 inch jaw opening....
And it's a pack of 4 for about $11 or so about $2.50 per clamp. I paid $2 per clamp and I got all of them in the Goodwill store. A couple were bigger but same price. I got 17 in total.
great canvas clamps for photography, fabric backdrops and green screen, painting and other craft projects.Exactly!! That's what I have a "canvas" that I need to clamp!!
The clamps get great reviews - very strong and don't scratch....
So in the UK this is how the same clamp is marketed....12 x LARGE 6'' PLASTIC SPRING CLAMPS MARKET STALL TARPAULIN COVER CLIPS GRIPS
US calls it "canvas" -
So I bought the perfect "kind" of clamps for what I want!!!
So
that's the same one - just different "brand."
So same clamps - advertised for canvas backdrop use...
71 customer reviews
And the tips have a articulating soft end that will not fall off like many of the metal ones.
So this is the same company of the clamp - it's not quite the same style of packaging but otherwise identical.
FINALLY - this is the exact same package and brand.
so my niece was playing with the clamps and I tell her how I'm gonna attach the tarp to the roof I showed her photos of. She then asks, "why can't I just use wood?" So I clarify - you mean a wooden roof? Yes... Oh because this is BREATHABLE!!
So then I show her the label....

If water pools over these sewn areas, the seams may leak slightly. Made in USA.So I should spray the seams on the bottom tarp - with extra silicone....

AND....
another take on the same tarp!!
Exactly!!!!!! really?
Cheap tarps driving you mad? You need a Weather Tough® tarp! This rugged 14.5-oz. polyester- and canvas-blend tarp is waterproof like poly and breathable like canvas. That means whatever you're covering is protected from rain, snow and sun while preventing mildew and damage due to moisture. Tarp features brass spur grommets that don't rust or tear out like standard grommets.
Weather Tough Tarp Advantage Over Standard Polyethylene: 1. Breathability prevents condensation damage; 2. Stronger than polyethylene of equal weight; 3. Professional canvas appearance; 4. Won't crack in cold; 5. Conforms to shape of object being covered.
Weather Tough Tarp Advantage Over Treated Canvas: 1. Completely waterproof; 2. Twice as strong; 3. Non-chemical finish is stain- and odor-free; 4. Won't unravel when stitching breaks or is cut.
Polyester is a variation of another material within the polyethylene family. Polyesters a thermal plastic material dealt with woven or need a thread. Polyester fibers are mostly spun together with other natural fibers. Super heavy duty polyester tarp material is usually found in tent and awning material.https://www.tarpsplus.com/materials.html
wow - it really is a blend!
after ten hours - still not leaking!!

so "encrypt" means "double sided" I guess...............
anti-uv silicone coated fabric
Designed for all weatherability, including zero winter temperatures and hot summers, making it ideal for use as a roof cover.YEP - Exactly!!!!!!!!!!!!!!!!!!!!!!!!!!!!
700 degree high temperature heat splicing-no needle holes,no water leakage.
- Polyester fiber is tightly woven, thick canvas, waterproof and durable.
- Increase the encryption buttonhole, the inner diameter is about 1.7 cm, and the spacing is about one meter.
Oh Encryption is the buttonhole?
Encryption is a button-hole stitchSo turns out that the Mineral Wool is not available up north. So I'll pick it up on the way. I plan to spend close to $200 for the insulation!!!
So that's $140 for the tarps and $36 for the clamps...
So a $400 roof!!
That is my ONLY expense though.... so not bad.
INsulation plus that size type shed -- hmm could cost several thousand dollars for the wood, etc.
I don't even know if this "plan" will work though - but hopefully.
