New Home buyer,Metal Roof in Maine With No Sheathing? Please Help

Hello all,

I am a first time home buyer and looking into buying a new home. My wife and I have found the perfect home here in Maine, but found out today that the metal roof was attached directly to the perlins. I know typically there is supposed to be sheathing and a vapor barrier in between. I have found information on both sides of the argument, which have led me here. Is no sheathing adequate? How will it affect my energy use? and will it be a condensation issue? Is this ok for a cold climate here in Maine?

How safe is a Polystyrene Styrofoam board for me to use practically?

I bought an insulation board from a local hardware department superstore, and I have concerns of it blocking my vent. I do have a couple of magnetic vent covers over my vent. However I'm concerned about a few factors. My room get's very HOT easily. I especially learned this when the sun rises every morning it shines against my room and burns it up into an abysmal inferno. It's the middle of the dead winter and I'm waking up finding myself soaked in my own sweat. (Gross!) The board has a R of 75 Degrees (F), and like any other Polystyrene material it is combustible and very easily ignitable.

JM Spider overhead

I was planning on using JM Spider on the underside of my structural roof deck. (There is a layer of peel and stick and 5.5" of polyiso foam board above the deck so no worries about vapor permeable insulation inside). The installer is having problems with getting the Spider to stick overhead. The installer says JM changed the fiber recently and they are having difficulties with some wall installations too. While they are working with JM, I was wondering:

Has anyone here had JM Spider installed overhead recently?

Strapping material for rainscreen...plywood fir or spruce?

I'm ready to put the strapping on-top of my WRB, only I'm not sure what the best choice is.

I want a 3/8" gap, so cutting plywood strips is my only option (there is NO composite furring strips available in town...I called everywhere!)

I've got the option of 3/8 spruce with exterior glue, or 3/8 fur with exterior glue.

Does either have a lower tannin content that may deteriorate the WRB? Do I even have to worry about that? Should I back prime the strapping to avoid this?

I'm going to put cement board over the strapping then stone.

Thanks!

Structural Insulated Panel (SIP) roof decay

I have a BensonWood timber frame in Vt that is only 8 years old with significant panel roof decay. So much so that my standing-seam metal roof has begun to rust from the inside out. There is evidence of SIP seam failure in several places below the standing-seam metal roof. Is it likely this was the cause? It is a hot roof.

Suggestions/advice on vapor barrier product to use?

In the basement of my house (built in 1900) in NE Ohio...Half of the basement floor is finished, the other half is dirt floor covered by a few inches of crushed stone gravel. I had a mold issue, so looking to put a vapor barrier over the gravel floor. Also am getting slightly elevated radon level about about 4.9 to 5.1. I'm hoping maybe to solve both issue with one fix. Here's my dilema...I'm looking for a vapor barrier material that would withstand occassionally walking across it.

Obnoxious blinking audio ads

I have clicked on a few ads. But will only support those that display motionless still quiet ads. More than that and you lose me, and forms of violence could well takeover an individual.

Pushy ads suck.

Bug screen for rainscreen strapping...how wide to cut?

I'm a rookie with this. First time building a rainscreen. I've got my WBB on the house and would like to apply my 3/8 strapping to create and airgap.

I picked up a few hundred feet of 4' bug screen and I will first apply a layer top and bottom, then my strapping and then staple the bug screen on-top of the strapping making the air gap, hopefully, bug free.

Thicker walls

I live in Minnesota. I'm remodeling an older home with full 2x4 studs. On the outside there is a layer of 1 inch buffalo board and 1 inch foil covered foam.
Is it worth the time and money to add wood strips to the 2x4's to make them 2x6's on the inside and go from a R-15 to R-19 or 21 insulation or add 2 inch certifoam to the outside or should I just leave it alone with 2x4 walls and R-15?

Thank you
