While doing your research on insulating your attic you may have come across a term you’ve never heard of before – hot roof.

So what exactly is a hot roof? Well, it’s probably not what you think.

RetroFoam of Michigan has more than 15 years of experience, and when it comes to terminology in the field, we’ve got you covered. In our ongoing efforts to educate homeowners, we will explain what a hot roof is and what that means for your home.

What is a Hot Roof?

The term hot roof comes from the earliest days of insulating attics.

Some people believed insulation was actually a heat source, even though in actuality it is a barrier between two areas of different temperatures. For example, your attic space compared to your snowy roof.

Even though the term “hot” roof is a bit of a misnomer, you’re still wondering what exactly it is.

Another term that describes a hot roof much better is unvented attic. If the roof deck of your home has been insulated, it is actually now a part of your home’s conditioned space. This is a great benefit as it helps prevent ice dams and helps save you money on monthly energy bills.

As for the “hot” roof theory, the unvented attic system could make the temperature of your roof go up a little, but fear not. This possible temperature increase of a couple degrees won’t cause damage to your roof or shingles at all. In fact, the insulation will make sure the only thing your shingles have to worry about is the sun, which they are designed to handle.

Want More Info on the Benefits of an Unvented Attic?

It’s too bad that an unvented attic is called a hot roof because it is much more about having a conditioned attic that doesn’t cost you money on monthly energy bills.

Don’t let that ominous hot roof label fool you, it’s one of the best options for your roof as it will save you from costly repairs from damaged caused by ice dams.
