Soffit Areas/Underside Of The Roof Construction Problems
Under-insulated Compression of common insulation or improperly-fitted batts in soffit area lowers R-value.
Wind-washing Air movement through air-permeable insulation lowers R-value up to 50% or more
Ice-Damming Reduced R-values causes melting of snow and re-freezing into ice, which blocks proper drainage, and potentially leading to extensive damage.
