Why Proper Ventilation is Important for Your Roof’s Longevity


Ventilation is one of the most important functions of your roof. While protecting your home’s interior from the elements is critical, you can’t ignore the negative effects of poor attic ventilation. We’ve compiled some information for you on how your roof’s ventilation system increases the longevity of your roof using soffits and fascia in St. Louis, MO.


Removing Moisture – Humidity in the home can cause a lot of damage. When you have proper ventilation in your attic, the interior of the home remains dry. This prevents issues like rotting wood and mold from affecting your roof. Excess moisture in your attic and roof can lead to costly repairs or even a full roof replacement.


Preventing Ice Dams – Ice dams are formed when snow on your roof melts and then re-freezes. This can cause severe damage to your roof. With proper ventilation, snow accumulation is more evenly distributed.


Preventing Leaks – When your attic is not properly ventilated, condensation can collect and leak into your insulation, causing a whole host of issues. While soffits and fascia can prevent water from entering your home from the outside, the moisture build-up in a poorly ventilated attic can still cause severe damage.


Mitigating Air Pressure – Heat rises, and if that heat has nowhere to go, it can cause major problems for your roof. The pressurized heat in your attic can damage your shingles from the inside out. This is especially true for asphalt shingles, which are more sensitive to heat.


Poor ventilation in your attic can severely impact the longevity of your roof, so it pays to make sure air is flowing properly through your attic and roof vents.
