You have ice coming through the soffit because the Ice and Water Shield is installed incorrectly to stop or prevent ice dam
leakage. The water and ice is also in the wall cavity between the sheetrock and the outside siding and leaking out through the siding. Wherever ice is on the outside wall and coming through the soffit the insulation inside the wall directly behind may need to be changed and the studs dried or you could possibly develop black mold
. Please understand, no insurance company will cover the removal of black mold so have inside of the walls checked for moisture. If it's wet, put a hole in the wall for insurance adjuster to see because they only cover visible signs of damage.
