Your roof is a workhorse. Day in and day out, it stands strong against the elements, keeping rain and heat out and your home’s ambient temperature in. Without its steadfast protection and the help of roofing contractors to maintain it, your home certainly would look a lot different!

However, steadfastness aside, you do want ventilation in your attic space. We know that sounds somewhat paradoxical! If your roof is supposed to be a stalwart barrier against the unpredictable weather outside, then why would a great roofing company like us recommend there be holes in it? 

While there may be some exceptions to this rule – some attics, for example, are designed to operate without ventilation – vents in your roof play a number of helpful roles, all of which enable that roof to serve its original protective purpose.

Proper ventilation helps keep water damage at bay.

Weird, right? You’d think that if your roof wasn’t airtight, rain would find its way in and create the notorious nuisance that is water damage. However, without strategically placed vents, the opposite tends to be true.

Humidity from day-to-day activities, such as showering and washing dishes, can make its way into the attic space. Without ventilation, that water in the air has nowhere to go, resulting in the eventual degradation and rotting of the wooden parts of your roof. If the damage from a lack of ventilation is severe enough, you could need a whole lot more than roof repair!

Proper ventilation helps to prevent ice dams.

A well-known Minnesotan menace, ice dams are formed through a complicated interaction between warm temperatures of an under-ventilated roof and the colder temperatures outside. (Learn more about these wintertime hazards and when you might need roof ice removal here.)

Unchecked, ice dams can cause standing water to back up underneath your shingles, further compounding the moisture damage that plagues a poorly ventilated roof in the first place. Trust us, soggy roofs are absolutely not something you want to deal with!

Proper ventilation allows your insulation to do its job.

Your insulation is the fluffy or puffy stuff in your roof that acts as a barrier between the cold air outside and the warm air inside your home. When subjected to the moisture damage that comes from a lack of ventilation, your insulation becomes sopping wet and sad-looking. More importantly, it can no longer protect your home’s temperature if it’s waterlogged. Say hello to sky-high power bills!

As you can see, proper ventilation is a must if you want your roof to perform at its best, and from preventing moisture damage to keeping your home’s air temperature comfortable, a few little vents go a long way.

Does your roof have ventilation issues?

Don’t go poking your head into your attic space to make judgements just yet! While an informed self-inspection is a great way to assess if your attic potentially has ventilation problems, only a condo contractor or the like who specializes in roofing issues will be able to tell for certain. This is for a few reasons:

●      Every attic is designed differently.

As we stated above, every attic is unique. What might be problematic in one attic might be perfectly fine in another (though, of course, there are some things that are universal issues). You can read all you want about ventilation problems online, but the person who wrote that information will never be able to speak for your home and attic’s individual experience – unless, of course, they’re on the scene and investigating for themselves.

●      Ventilation issues can be tricky to diagnose.

A given occurrence in the attic can stem from many potential issues. Frost, for example, is sometimes just a sign of low outdoor temperatures, while in other cases it very well can signal a problem with your ventilation. Air leaks in the attic can often disguise themselves as ventilation issues, but fixing them as if they were can actually make matters worse.

An experienced eye is thus paramount if you’re concerned about ventilation, as any issues will be quickly pinpointed. Throwing stuff at the wall and seeing what sticks absolutely cannot happen – you already know the dangers of a poorly ventilated roof!

●      Your attic can be a dangerous place.

Of course, if everything is working as it should be, you’ve got nothing to worry about. However, ventilation-related issues that cause moisture accumulation can make the area potentially harmful. Water near electrical systems and potential mold growth in a worse-for-wear attic are not something you should ever have to deal with, so let a professional do the dangerous job for you.
