Recently I blogged about ice damming and signs that this serious problem is affecting your Columbus roofing. This week, we’ll take a look at smart precautions you can take to prevent ice damming and, as a result, roof leaks.
There are several ways to prevent ice damming, many of which focus on controlling energy loss. In addition to eliminating ice dams, a “whole house” approach to improving energy efficiency can cut your total energy consumption by up to 40%, saving considerably on utility bills.
1. The #1 way to prevent ice dams is to increase the amount of insulation in your attic to keep heat from escaping to the roof deck and melting snow on the roof surface. Franklin County requires an R-30 insulation level, and Delaware County requires an R-38. The Department of Energy recommends from R-40 to R-60.
2. Proper ventilation directs heat and moisture where they need to go. Install intake and exhaust vents to allow warm air in the attic to escape quickly. Make sure all bath fans and vents going into your attic are connected to pipes that protrude out of the roof, and are flashed properly.
3. For a new roof, install ice guard up the roof two feet from a warm wall. This usually can be accomplished with one course of ice guard, but some homes with large overhangs will need two courses.
4. Install heat tape on the roof, such as Frost King Roof & Gutter De-Icing Kit.
