Roof Ventilation 101: Why It Matters and How to Improve It

Writer: Staff Desk Staff Desk

Have you given your roof ventilation a thought recently? If it hasn’t come to mind in the past year or if you are asking, “what even is roof ventilation,” you’re not alone! It’s one of those behind-the-scenes home features that often get ignored until a problem rears its ugly head.

 

But, here’s the thing: proper roof ventilation is not just recommended. It is in fact essential if you are looking to keep your home comfortable for the long run. It also adds to the energy efficiency of your home and keeps you shielded from costly damage. Let’s understand why it matters and how you can ensure your roof is properly ventilated.  

 

Why Roof Ventilation is a Big Deal

If the house was a human body, the attic would be its lungs. Without proper airflow, things can quickly get hot, humid, and unbearable. Here’s what good roof ventilation does for you;

 

  1. Temperature Regulation: In the summer, hot air often gets trapped in your attic which pushes your air conditioner to work overtime. Proper ventilation allows that heat to escape and keeps your home cooler, and energy bills lower.

  2. Prevention of Moisture Damage: In the winters, warm air from your home will rise to the attic where it can meet the cold surface and cause condensation. Over time, unless taken care of, this moisture will lead to mold, mildew, and even cause structural damage. 

  3. Extending Roof Lifespan: When your roof gets exposed to excessive heat and moisture it can warp the shingles and deteriorate roofing materials. A well-ventilated roof keeps those shingles intact for longer and saves you replacement costs.

  4. Avoiding Ice Dams: Do you live in a colder climate? You might have come across ice dams which are essentially ridges of ice that form around the edge of your roof. Poor ventilation leads to this issue as it allows heat to build in the attic and melt snow unevenly. With proper airflow, you can avoid this headache easily.

 

Improving Roof Ventilation

If you want to improve your roof ventilation, you must start by looking out for red flags and getting issues fixed ahead of time. Here are some warning signs;

 

  • Your attic feels like a sauna in the summer and freezes up in the winter.

  • You notice mold, mildew, or musty smells.

  • Your energy bills creep up without any reason.

  • You see peeling paint or warped wood near the roofline.

  • You keep coming across ice dams in the winter.

 

If you come across any of these signs, you should consider contacting a professional Wilmington roofing company before the problem gets worse!

 

Here are some tips you can use to improve your roof ventilation right away;


  • Add soffit vents (intake) and ridge or gable vents (exhaust) to keep the air moving.

  • Invest in a ventilation fan to boost that airflow.

  • Check for any blockages in the vent caused by the insulation, debris, or bird nests.

  • Upgrade that insulation if it is blocking airflow.

 

Final Thoughts

Roof ventilation might not be in the forefront of your mind, but once those energy bills start rising or you begin noticing mold, it may be too late. We suggest getting that roof looked at every once in a while, to avoid big problems!
