HELP! I HAVE ICE ON MY ROOF!! WHAT DO I DO??
We get calls every year from customers saying, “I have ice on my roof. What should I do?” The answer may surprise you! Portland winters are usually mild, but every so often, we experience a cold snap that brings snow and ice. When that happens, homeowners often wonder what they should do about the buildup on their roofs. The simple answer? Stay off your roof and let nature take its course.
Unlike areas that experience heavy snowfall every winter, Portland’s winter storms are typically short-lived, and in most cases, the best approach is patience. However, there are a few things to keep in mind when dealing with snow and ice on your roof.
Should You Remove Snow or Ice from Your Roof?
For most homes, removing snow or ice is unnecessary and can do more harm than good. Trying to knock off snow or break up ice can damage your shingles, gutters, and other roofing materials. Walking on a snow-covered roof is also extremely dangerous, especially with icy conditions. Instead, let the sun and rising temperatures take care of the job naturally.
What is an Ice Dam?
One rare but notable phenomenon we sometimes see in Portland is an ice dam. This occurs when heat escapes from your attic, causing snow on the upper part of your roof to melt while the lower portion remains frozen. The melted water runs down the roof but refreezes at the colder eaves, forming a ridge of ice. This dam prevents proper drainage, leading to water backup under shingles and potential leaks.
However, an ice dam does not necessarily mean you have a true roof leak. Water may temporarily find its way under shingles in extreme conditions, but this doesn’t always indicate a long-term issue. In most cases, once the ice melts and normal drainage resumes, the problem resolves itself.
How to Prevent Ice Dams
Improve Attic Insulation & Ventilation – A well-insulated attic prevents heat from escaping, reducing uneven melting on the roof. Proper ventilation helps regulate temperature and moisture.
Keep Gutters Clear – Clogged gutters can contribute to ice dam formation by preventing proper drainage. Regularly clean out leaves and debris, especially in the fall.
Assess After the Melt – If you suspect an ice dam has formed, wait for a full thaw before assessing any potential damage.
What If I Notice Damage After the Snow and Ice Melt?
If you see signs of water stains, missing shingles, or sagging gutters after a storm, it’s best to have a professional inspect your roof. However, don’t panic if you noticed minor water intrusion during an ice dam event. A one-time occurrence in extreme conditions doesn’t necessarily mean your roof is failing. If you’re unsure, Orion Roofing offers free inspections to assess any damage and recommend the best course of action.
Final Thoughts
While it may be tempting to take action when snow and ice accumulate on your roof, the safest and most effective approach in Portland’s climate is to wait it out. Avoid climbing onto your roof, let nature handle the melting, and check for any signs of damage once the weather clears.
