Is a partial unvented roof retrofit a bad idea?

We are in Minneapolis with a 1923 Tudor house. Last year was our first winter in the house. We had bad ice damns last year and there is plenty of evidence it has had problems in the past. The second floor is a full story and consists of a shed dormer addition with no venting that I can see. The rest/original of the roof has minimal venting due to lack of (none) eves. There are only pots, but no soffit venting. Half of the story is unconditioned attic is accessible and is on the same floor as the living space. Access through a full size door.

Be new 2x4 wall.
There would be no brick mould.

But the flashing details would be a concern
Any suggestions.perhaps using a product from tremco called exoair

Bathroom remodel plans call for 3 sconces next to medicine cabinets (two 60-watt bulbs each in frosted glass fixtures)

Plans also call for two 4" cans 5 feet behind sinks for lighting by the closet. The contractor wants to add two recessed 4" cans above sinks (on dimmers). We also have a large skylight in the room. Advice? Thank you!

If necessary, could the Zip System 5/16th sheathing survive a New Hampshire winter without siding?

We need some honest opinion and some guidance.

We are building a small summer home in northern NH. We had a family member pass away and have had to take time away from building in order to put some family affairs in order. As a result we won't be able to complete all the work we need to complete before we leave in a week.

We don't think we have time to put up siding before we go.. However, the sheathing is mounted and taped on the house. (The roof is shingled already.)

Left as such, would the Zip System sheathing survive a New Hampshire winter without siding to cover it?

Attic fans

I live on Long Island in NY state close to the ocean and have two fans in my attic -- they have been there since I bought the house and I have already replaced them once BUT after reading your 10/12 article re these fans, I'm wondering if I should disconnect them. My attic floor is insulated with blown in cellulose and I have soffit vents and four normal passive vents already in the roof. I do have my air-handler in the attic along with soft duct work to various top floor A/C outlets. My home is 73' x 31'

Attic fans with a hip roof

Sorry if you think I didn't understand your very clear article --- my mistake, since I did not mention that my roof is a "hip" roof and I heard that could make a difference since ridge ventilation may not function with a hip roof. I'm thinking that my four passive vents along with the natural vents created by two non-working attic fans may be enough? Just wanted an opinion re a 73x31 hip roof.

Attic ventilation questions

Hi Guys,

So after getting a $310 bill from the folks at Duke Energy last month, I decided it was time to figure out a more efficient way to cool our home. I've since asked them for their free energy audit to identify areas where I can save energy.

Air space or rigid foam to insulate on exterior of block wall that will have furring strips for vinyl siding.

I've been googling and cannot find info close to my situation. So I am hoping to get some ideas here. I have purchased an old building with block walls and no windows. It is the corner eyesore but is useful as a secondary shop for me, plus it zoned as commercial property, which you never know when having a commercial address can be beneficial. Anyway, I only plan to use it as a workshop, so optimal heating isn't crucial. However, being an eyesore, and my experience with painted exteriors in Michigan, I plan to vinyl side the building, which will include furring strips.

Help with knee wall insulation project

Hello, I am looking for some help with an insulation project for a knee wall in my old Bungalow style home. I am in Michigan so the winters can be very cold and summers hot/humid. I am currently insulating the knee walls in the upstairs area where our bedroom is. The bedroom gets extremely hot in the summer due to the knee walls, but somehow stays relatively comfortable in the winter.
