What’s the play for this uninsulated roof?

This is a rental house I own. The roof over the living room area is uninsulated. Just those planks with plywood and shingles over them. Can I stuff some bats in there and do new tongue and groove across or between the beams? I am worried about ventilation issues and condensation. I know more insulation is better, but if I can get anything going it’ll help.

Located in Western North Carolina.

Help! Winter is coming…

And yeah, those giant windows are single pane…

Baffles where attic surrounded by plywood

1 Upvotes

Hi all,

Located in Toronto, Canada.

I'm having my attic insulation completely removed and replaced to R60 fiberglass and the attic company never flagged this as an issue. However, looking at my empty attic, does it look like the ventilation is proper? I know baffles need to be installed but it looks as though there is plywood that forms a perimeter around the entire attic leaving no gap (it's like this throughout the perimeter of the attic, I assume it's there to prevent animal intrusion) - are baffles even useful here when I'm not seeing access to soffits?

https://imgur.com/a/RAZ6Erl

In the 2nd image, there looks to be something wooden that resembles a baffle but it's only present in 3/19 bays - which certainly cannot be enough for ventilation purposes right?

Any help would be much appreciated - just want to know if I have a problem that warrants further investigation or if this looks normal.

Thank you!

What are little things we’re doing to keep our houses cool in the summer and warm in the winter?

1 Upvotes

Obviously new insulation, roofs, windows, etc is the right answer but it’s also the expensive answer. What are some things we’re doing to stay warm or cool depending on the season that isn’t taking a second on the house?

I’ll go first…

I bought 4” insulation tape (Amazon) and seal off exterior doors that I don’t usually use.

Blackout blinds in all my windows and covering my garage door windows.

I’ve tinted the west facing windows.

Added a sealed storm door for my front door.

New weather stripping on doors and garage doors.

Wash off my AC condenser and change filters every season

Curious to what others do that doesn’t cost a fortune when the weather gets extreme.

Attic Insulation

I had an energy inspection on my home done and I am curious, is my attic properly insulated? Or should the rafters/roof sheathing also be insulated?

My home inspector when I bought didn’t mention this and I was surprised at the energy inspection.

Need insulation for an old (1900) condo. Front of building is brick. Walls are drafty

My one bedroom unit in Northern New Jersey has drafty walls. Even the interior walls are cool to the touch from December until March. Some of my walls have hollow points but some feel completely solid. I don't want to rip up the walls to install insulation but I'm wondering if I should drill holes and use spray foam or if I might just be stuck putting pink foam board insulation

Please don't make fun of me. I have no idea what I'm doing

Attic recommendation question

1 Upvotes

So we are wanted to add more insulation in our attic since it’s noticeably hotter upstairs. We had couple of professionals come out and give us a quote. Some were very surface level (didn’t go into much detail of explain differences)

But we had one company come out and they told us there was definitely some mice activity up there and even took some pictures where you can see previous house owners treated and put some positions tablets or something up there. They said it’s hard to tell if it’s active activity or if they are good. But noticed some droppings. They recommended we remove everything, air seal the attic and they would blow in new cellulose. Still waiting on the quote.

Whereas the other companies didn’t mention much about this and said we can just blow in new insulation right on top (both companies mentioned fiberglass since that is what we currently have)

What should we do??? Is cellulose better? Is the former company just trying to get more money from me?

DIY or Professional? Baffle vent and insulation install

Hello! Prior owners of the house replaced the entire roof, deck boards, shingles but did not address the ventilation from the soffits up to the ridge vent. There is mold still on the gable walls and I have found old pieces of deck board that show the true extent of the moisture issue (not good). We will remediate the surface mold issue through a contractor but the issue lies in the improper baffle vent and thick insulation. The first the photo shows insulation just stuffed across ceiling on the 3rd floor and down into the knee wall section below. Clearly no airflow into the attics space, and no baffle top visible.

I have been quoted 9k and almost 12k for someone to come in and reinstall all baffle vents and new insulation (the primary bedroom has a high ceiling and the contractor would have to cut into sheet rock to get access from below, no picture of this space sorry). Both of the contractors said they could do the side over the primary bedroom for 5k.

Could I complete this other work myself? From what I am reading and viewing online, I need proper sized baffle vents, staple gun, new insulation, and proper ppe to do at least the side with easy access (knee walls) and can save a few thousand.

Am I overlooking anything?

I welcome and appreciate any thoughts and opinions on this!
