just ordered a Pond Liner as my hermit hut roof. haha. I got the idea
from "Uncle Mud" - this cob builder rocket stove gasifier dude online.
So he says the rubber epdm is way less toxic then the other roof liners
and I won't use any glue - just put it under my "industrial tarp." He
said - I don't need a breathable roof - and I realized yeah since my
walls have holes in them anyway then I don't need a breathable roof.
haha. And I was able to order directly from a company in North Carolina -
not using the evil Bezos with his slaves so he can be a Trillionaire.
And so more evil synthetic rubber.
Uncle Mud - rubber pond liner for a living natural roof - video
pond liner - great idea! I actually was searching for a roof liner and did not want to deal with the synthetic toxic sticky stuff. Having a green roof is an excellent idea - that's another reason I wouldn't want metal - it's too loud and so would scare the birds.
EPDM "fish safe" pond liner is a lot less toxic than the other options, also more expensive and heavier but worth it. Sometimes for small projects like this you can get a deal on a remnant or leftover scrap at the end of the roll.
@Uncle Mud good idea. Although the ReStore place for Habitat for Humanity seems kind of limited. I'm out of the big city now though - so probably better in the city. Actually where I'm at there's not many ponds or pools - I live in the land of over 10,000 lakes. haha. So my neighbor lives in a tiny house he just built but his land just has a garage permit. So I called up planning and discovered this loop hole - they said yeah we give out a street address for a garage permit assuming it to be a permanent primary structure (as part of a residence). So you can get a street address without actually needing a residential permit first requiring a septic permit - because a garage permit is an accessory permit. Wow - quite the loop hole! So then I immediately bought a "garage in a box" at Harbor Fright. So then if I do want a street address so I can have a car driver's license - then I just need to convert the garage into a permanent structure. On the other hand NOT having a street address means I'm better hidden from all the evil.
But I would still be limited to seasonal camping in a tent for seven months a year (which is allowed in my zoning). Although the primitive Double Wattle Wall insulated clay slip straw shack I built - could still be used for storage, and occasional sleeping, etc.
So I would just camp in the state or national forest for the rest of the year. So I would be technically be homeless unless I can do the whole "permanent" garage in a box conversion. haha. I'll keep an eye out for pond liners. I got nail pulling tools - so I'll start compiling pallet wood to use for the framing and walls and roof, etc. That will be a lot easier than harvesting all the willow - albeit less primitive looking. Still civilization should collapse soon - in a few years probably or five at most. I'm not planning on moving soon - I just farm shiitake mushrooms now but maybe I'll start planting chestnut trees since it's already 2 degrees C warmer than usual where this land is at. thanks
@Uncle Mud OK Uncle Mud - there's a company in North Carolina shipping pond liners for cheaper than the 12 x 16 poly-canvas grommet industrial tarps I've been using as my roof so far. So I ordered a 10 x 12 pond liner as that is my building size. So it won't cover the whole roof but should be good enough. I'll just put it under my other industrial tarp - once the spring hits. I'm in the coldest spot in the lower 48 - so - I obviously have to wait. Thanks for this idea. Because obviously the UV was degrading the poly-canvas tarps and I had three of them. One is under the rockwool - to hold in the rock wool insulation. Then two on top - so to keep the roof taunt so it doesn't collect water. So this rubber liner should help to stop water collecting since it will be really water proof instead of just water resistant. haha. Thanks again Uncle Mud - and I did NOT have to order from the evil trillionaire business with his evil empire of slave minions.
So based on that explanation page - this liner will weigh 50 pounds!!
That's amazingly cheap for shipping cost included - it was just $110 for a 10 x 12 liner.
Of course the environmental costs are another thing.
Wow the PVC roof liner is $80 but you get tons of Toxic Off-gassing - NO WAY!!!
Lets talk about PVC liner first. PVC liner is super cheap and really
easy to work with since it is so thin. PVC liner is lightweight compared
to heavy duty Firestone EPDM and often costs much less to ship. Sounds
good right? Now the downside. Liners containing PVC are made with
plasticizers to keep them flexible. Over time, or when exposed to the
sun these plasticizers leach out of the liner leaving it brittle. In as
little as one year a pvc liner can be brittle enough to split open under
the weight of your pond water and one day you look out to find an empty
pond. It is possible to cover the PVC liner with enough rocks and dirt
to prevent the sun from reaching it and this will give you a few more
years of use.
So there is a "polypropolyene" under-layer protection liner - but how is that different than EPDM?
EPDM rubber belongs to the thermoset elastomers (rubber) classification, while PP
copolymer belongs to the thermoplastics. There are 6 material
properties with values for both materials. ... For each property being compared, the top bar is EPDM rubber and the bottom bar is PP copolymer.

Ethylene Propylene Diene Monomer
(EPDM) membranes are incredibly environmentally friendly and offer a
range of benefits for your flat roof. If you’re a homeowner in the UK
looking to lead a sustainable, energy efficient life, then rubber roofing is for you.
Yeah I don't know about "friendly" but definitely LESS toxic - way less toxic than PVC!!
So here is the evil Trillionaire site for Firestone Rubber Roofing - it's thicker than the pond liner
This is rubber innertube tire material. Thick! Heavy in pounds of sheer weight too
But since I will NOT use toxic adhesive (on both sides) but instead use the Poly-Canvas tarp (on both sides) - then I do not need this thicker liner.
OK the Firestone roof EPDM liner is also sold as 45 mm
It is 45/1000 of an inch thick.
strange standards.
mine had about a 10-inch difference in width from one end to the other, falling short of the 10-foot width I paid for.
Hmm - we'll see.
Nice
thick rubber mat I used on a flat roof that is on my cabin. Anything
else would have leaked because there is no slope to the roof. This
rubber seems to be very tough and was very easy to lay down.
right - so the slope at the edge of the walls will not be covered but it should be good enough to prevent any water from leaking through where the roof tarps are not taunt enough farther up the slope.
Oops - they have this IN STOCK locally but it's actually too big for what I need.
That's a 10 x 20 foot as a 10 foot roll!!
http://www.stafastbuilding.com/stafast/epdm.html
So it's a different brand - NOT Firestone!

vid of 200 pound 10 foot roll as roofkit

So sure enough - just like the Pond Liner - they sell it folded in a box but the size is too small - (and it's only in the UK)...
amazing.
So what I ordered should weigh 50 pounds probably.
OK so the 10 x 20 foot roll will be too short for length and too wide.
I can fold the sides to make up for the width.
Then the 12 foot pond liner will cover the length but be four feet not wide enough.
So if I double up - people say the 45 mm is too thin and so degrades over time.
So if I just put two of them down then I will have the roof completely covered with a double layer as 90 mm. It is sold as 90 mm anyway.
36 lbs
https://www.pondliner.com/10-x-12-firestone-pondgard-45-mil-epdm-pond-liner
OK so that is a different company selling for $80 but I'm sure not "free" shipping!
yeah the 10 x 20 Pond Liner is more expensive from Firestone than the 10 x 20 roof kit roll from stafast roofkit.
