Knoxville’s Old Three Tab Roof Has Major Hail Damage From an Old Hail Storm. This recently purchased home in Knoxville Tn shows signs of a major hail event likely from a decade ago. The roof is in very poor condition, and the gutters are old and hail damaged. The roof is fairly steep, which might explain why water has not been pouring in. This lovely home in West Knoxville will look great with a brand new shingle roof!
