Every winter we see icicles hanging on gutters or eaves, especially living in northeast Ohio. As much as we believe icicles are another aspect of a “winter wonderland”, they can become a winter nightmare. Icicles can and will cause damage to your house. Types of damage is falling gutters, loose shingles, and water pouring into your house. All scenarios are detrimental, however, water entering your house is the worst. Water will affect your insulation inside the attic (lose its R-value, lead to mold), damage paint, deteriorate the drywall, ruin wooden joists, and cause headaches.
That will cause structural damage to your property and cost thousands to repair.
