It’s not uncommon for homeowners with metal roofs to be concerned about ice damage. When the temperatures start to cool in the late fall, the outside cold air combines with the indoor warm air, and this can result in condensation.
When condensation forms on a metal roof, it might seem like there is damage or your roof is leaking. But this isn’t the case. Just as a glass will “sweat” when it is filled with an ice-cold drink, moisture can accumulate on the outside of any roof. The effect just seems to be more evident with a metal roof because some materials, like wood, will absorb temperatures quicker. And it’s also just more noticeable on metal than asphalt or tile.
How to Minimize Condensation on Your Metal Roof
A small bit of condensation isn’t going to damage your metal roof. But you can still take some steps to minimize this effect. The easiest thing to do is address what is happening in your attic.
That space above your living area and below your roof is going to get understandably cold during the winter. But you can minimize roof condensation by installing a vapor barrier in the space and around your ceiling’s insulation. This will also keep your home warmer and reduce your energy costs.
Another way to minimize the chances of moisture collecting on your roof is by finding and eliminating sources of cold air entry. This might include ceiling fans and light fixtures that are unsealed as well as dryer vents and exhaust fans that could blow moisture directly into your attic.
Finally, how your metal roof is installed matters. Your metal roofing company should ensure that there is a strong foundation for the roof. This alone can help minimize problems with condensation.
What About Ice Damming on a Metal Roof?
We live in a climate that gets incredibly cold in the winter months, so ice damming could be another issue. This occurs when it’s cold outside, and snow melts in spots on your roof where it is warmer. As ice and melted snow try to slide off of your metal roof, it might hit areas that are colder and refreeze. Ice can build up over the roof eave and under panels, resulting in leaks.
This scenario sounds terrible but similar to condensation, it’s preventable. As long as you have adequate ventilation and insulation in your attic, you probably won’t run into issues with ice damming. There are even specialized products available to ventilate and insulate cathedral ceilings, which have historically had these types of troubles.
