Can I add insulation with no soffits?
thehpw

Hi, I have a 1953 home in Redondo Beach CA that has no soffits. The house has vents on the roof and on the sides and I dont see any signs of moisture or mold. I am planning to add insulation all the way to the ends of the attic since the home has no soffits. It almost never gets below 40 degrees here, and never snows, so is there any concern with adding insulation all the way to the ends? Thanks : )

You can add insulation, as long as you maintain air circulation in the attic, meaning: don't block vents.

Do you have vent openings on top of the exterior walls, just below where the roof starts? If you do, these vents should remain uncovered.

No, there are no vents on top of the exterior walls, no ridge vents only vents on the sides of the attic and thru the roof itself. Seems as thats how all the homes are around here.

You don't need as much attic ventilation where you live as most people do. It sounds like you are describing gable vents which are at the top of your gable ends. You need two vents, one at each end of the house with about 1 square foot of gable vent for every 300 square feet of attic space. So if you have a 1500 sq ft attic, you need two or more vents totaling 5 square feet.
