Be Better Than Spray Foam!!!!!!!!

FRIENDS!

Let's think more about insulation...

TWO VIDEOS ON MYCELIUM

ACK! THE ROOF: TO VENT OR NOT?

Reader beware...

Nuances of this roof:

• Rafters (2"x6" ripped to 6" "exactly") are running parallel to the width (not length as is standard)
• I'm planning on using two pieces of 2 5/8" rigid foam between the rafters, (potentially) leaving about 3/4" space for venting (holes in rafters and blocking could allow for venting from side to side of the house, OR from eave through rafters up to ridge)
• There is 2"x6" diagonal blocking (not 6" exactly) with an 18 gauge metal strap nailed into it
• I'm stubborn about not wanting to use plywood for sheer strength
• the vapor barrier on the roof (bitchathane/ ice & storm most likely... .... ....) needs a consistent uniform surface to lay upon; Therefore, if I do vent at the top, I imagine I'll need to sandwich a few layers of corrugated plastic (same stuff ridge vents are made from)
• It is possible to vent the longer side (seen with the diagonal in place) but not the loft side (which will have a hatch roof that pops up)
• There will be small windows at the loft level to open for ventilation

IF NO VENTING
PROS: I just want to put the roof on, enough already

CONS: worried about mold developing in ceiling

IF YES VENTING
PROS: the roof is vented! longevity
CONS: pain in the neck, less space in loft's head room

BOTTOM LINE:
I have to make a decision. The rain is coming.

The fact is: LOOK!


From yet another northern California remodel gone... gone with tons of waste. Enter, some perplexed scavenger who doesn't even like the stuff, but now has a mountain to build her home with. Strange indeed. Thanks to the fellow in Sebastopol for posting this on Craigslist rather than putting it in the dump. And to my mom for letting me borrow her truck at 6:30am this morning to be the first to pick it up.
