Insulate Roof Or Above Ceiling In Eaves

You may not be able to see them clearly yourself but you can be sure that your hard earned hot air will.

Insulate roof or above ceiling in eaves.

In cold climates thin insulation near the eaves contributes to ice dams. This is the point where the roof meets the walls of the house and it s one place where small gaps and cracks are commonly found. The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow. Everywhere but climate zone 1 building codes require the installation of ceiling insulation rated at r 38 or r 49.

To be truly effective insulated areas must be tied down to the roof itself at the eaves. Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away. 2d extend insulation into joist space to reduce air flows. No your soffits should not be insulated and there is a chance that your insulation has been damaged by this.

In most of the u s. Achieving these r values with cellulose or fiberglass requires at least 11 inches of insulation for r 38 or 14 inches for r 49. For the same reason insulation shouldn t touch the roof s underside. On a positive note congratulations on having 24 inch eaves.
