My brother has an old house probably built in the 30s or 40s in renovated in the 50s. The very front of the house looks like it may have been a converted porch. There was recently a leak which prompted me to pull down some of the sheet rock on the ceiling. I was a little surprised to see that there is no insulation at all above that area ( which explains the heating bills ).
I’m wondering what the best way to insulate the area is. The roof is at about a 20 degree angle, do I insulate the area about the Sheetrock, or the angles of the eves? How do I make sure everything is vented correctly ?
