Ice dams on your roof spell trouble because of the excess water they can allow into your home can cause damage to ceilings, drywall, and insulation. The most effective method for ice dam removal is low pressure steaming. This technique separates the ice from the roof without damaging the roof’s shingles. For safety reasons, this process should be completed by a contractor using roof safety harnesses. An alternative technique for ice removal is the utilization of ice pucks that are placed on the roof with the intent to thaw the ice and create channels for trapped water to flow off the roof. While in theory, this can seem like a low-cost alternative to hiring a company to steam off your roof, here are six major reasons this approach is a no-no.
Salt that comes in contact with your roof has the potential to change the color of your shingles and not in good way. The white salty reside left over by the pucks will alter the appearance of the roof and have a negative effect on your home’s curb appeal.
Rusted Nail Heads
The shingles on your roof are fastened with nails. Nails that encounter salt begin to rust. This leads to rust spots on the roof. In addition, the rust minimizes the ability of the nail to hold the shingles in place, allowing for them to pull up.
Oxidation on Your Home
Salt that washes off the roof can corrode aluminum gutters and siding. The rate of oxidation is largely dependent on humidity levels, the alloy of the aluminum, and air temperature.
In the winter months, your home’s landscaping is hardly of concern. However, it should be. The effects of using salt pucks on your roof can create long-term devastating effects to your home’s landscaping. Salt that comes in contacts with various species of plants can compromise their ability to withstand arctic temperatures. In addition, salt that’s absorbed into the soil can absorb water that would otherwise be consumed by a plant’s roots, creating a drought-like scenario. Large doses of salt also make it difficult for grass to absorb oxygen and water, causing it to die.
If salt washes off the roof and meets a concrete sidewalk or driveway, the material often begins to crumble. This is because of the corrosion created to the rebar below the surface. Additionally, discoloration of the sidewalk or driveway is highly probable.
Whether it’s the pucks themselves falling off the roof or the remnants of the salt pucks being washed away in the rain, run-off proves problematic. This is because the elevated levels of salt make their way to groundwater, lakes, and streams. Introducing excessive salt to foreign water sources can hinder the ability for fish, birds, and aquatic vegetation to regulate fluids. The presence of salt also encourages damage to trees and erosion.
Ice Dam Prevention
Diagnostic testing by a reputable professional can allow them to pinpoint where a home is losing energy. Effective tools for evaluation include a blower door, borescope, smoke stick, and infrared imaging. Upon completion of the diagnostic testing, a contractor can put together a custom plan that addresses areas of your attic that require sealing.
