Any person who stays in cold weather areas should take preventative steps to secure their residence from the formation of ice dams.

Ice dams occur when roofing system rain gutters become obstructed with ice and particles. As water from rain or melted snow runs off the roof covering the seamless gutter, it ends up being trapped between the ice inside the gutter as well as the roofing system tiles. With no place for the water overflow to go, water can move back as well as beneath roofing shingles. Once the water takes a trip beneath the roof shingles, it may remain there for a prolonged period of time undergoing a lengthy collection of freeze/thaw cycles. Should sprinkle remain beneath the roof shingles, it won’t be long before the water begins to develop roof deck damages and timber rot.

Taking care of water damages as a result of ice dams is pricey.

Avoiding ice dams is very easy as well as inexpensive. Prevent ice dams throughout brand-new construction or re-roofing by using the complying with measures:

1. When mounting a brand-new roofing system, constantly install high-quality ice and also water obstacle on the first 3 feet of all roof covering eaves at a minimum (or 2 feet past the first indoor wall). Lower pitched roofings might call for 6 feet of ice as well as a water barrier or more. Minimum building code for most towns in Wisconsin call for ice and also water obstacle to extending from the edge of any roofing eave completely up 2 (2) feet past the interior wall. In a lot of scenarios, the roofing soffit (overhang) is 1 foot or less wide. As a result, basic ice and water barrier made in 3 (3) foot broad rolls will certainly fulfill the minimum building ordinance.

This is why most roofing professionals consist of one row (very first 3 feet) of ice and water obstacle in their bids for the roofing jobs. If you have a broader soffit, thoroughly read the minimal building ordinance for roofs in your town as well as be prepared to install more than one row of ice and water obstacle. Likewise, note that this is a “minimal” building ordinance. Generally talking, much more is much better in this scenario, but ice, as well as a water barrier, is reasonably pricey when compared to typical tar paper underlayment. One should weigh the costs and advantages of surpassing the minimal building regulations in this situation.

2. Mount seamless gutters and downspouts large sufficient to deal with all the water drainage from your roof. Many professionals will be able to compute the required seamless gutter ability based on roofing size. Bigger roofings will certainly require larger seamless gutters with more water ability. Customized smooth gutters are a little bit more expensive than premade gutters, yet they spend for themselves once you think about resilience and maintenance. Constantly make sure water has a clear path out of the downspouts and also far from the foundation of the house.

3. Maximize roofing system airflow by balancing consumption vents (soffit or gable vents) and also exhaust vents (ridge air vent or box air vent). There must be a 50/50 balance of cold air consumption vents and warm air exhaust vents in the attic room directly below the roofing system deck. Cold air from the exterior gets in the intake vents and also pushes cozy air out of the attic room with the exhaust vents in an appropriately working system. Without correct ventilation, cozy air becomes entrapped in the attic room. This cozy air will certainly warm up the roofing and also thaw any standing snow. At the same time, chilly air outside can freeze the melting snow and create ice, as well as the freeze-thaw cycle continues.

Ice dams on existing roofs can be prevented by complying with the actions listed below:

1. Maintain and also clean your gutters and also downspouts routinely. Make sure water can stream freely off as well as far from your roof. As soon as a downspout clogs and also water ices up inside a seamless gutter, it is far too late! Installation of rain gutter guards is an excellent financial investment that will save you time and avoid obstructions.

2. Mount warmed roofing system cords in areas where constant ice damming occurs. Heated roof cords are easily offered, a low voltage burner is connected to your roofing system eaves, and also rain gutters. These cords can protect against ice from creating, to begin with.

3. Mount extra insulation in attic areas to make certain cozy air from your home doesn’t run away into the attic as well as cozy the roof.

4. Compute the quantity of roof covering airflow that exists in the attic room space. Add intake or exhaust vents if there is less than 1 square foot of air vent location per 300 square feet of attic floor space. There should be a balance of 50% consumption ventilation as well as 50% exhaust ventilation.
