Ventilation is a key part of your roofing system and your home’s overall structure. Older homes and homes with poorly-installed roofs can have insufficient ventilation, which in turn impacts the circulation of air. As technology improves, roof systems are improved. Ventilation included. Today we want to talk about how insufficient ventilation decreases your roof’s lifespan to help you understand why proper ventilation is so important to your roof.

How Insufficient Ventilation Decreases Your Roof’s Lifespan
Without good ventilation in your roofing area, you are bound to have problems during both the summer and winter seasons. As the air heats up and gets trapped in your attic, issues with mold, warping, and moisture buildup can occur. During the colder months, warm air from below can get trapped under your roofline and develop problems like condensation, ice, moisture, rot, and more.
Over the years, these ventilation deficiencies can become a serious problem for your home’s roof and attic area, not to mention the integrity of the rest of your home.
Signs of Poor Roof Ventilation
Let’s take a look at common signs that your roof is poorly ventilated.
Rusting or Moisture Build-Up. Metal areas inside your attic can start to rust because moisture is building up and sitting on these components without ventilation to move the air around.
Damp insulation or Wood. The components under your roofline can start to accumulate moist areas that just aren’t airing out. They can become moldy, rot, and start to deteriorate.
Shingle Damage. Believe it or not, the shingles on your roof will start to wear more quickly because the ventilation isn’t adequate to allow for proper air circulation. Heat can build up under your roof space and heat up your roofing components causing shingle damage.
Improper Roof Vent Installation & How to Fix It
If your current home has a roof with improper or insufficient roof ventilation, you will more than likely have a problem at some point. And older homes simply don’t have the great ventilation like we have today.
Now we have great options for roof ventilation like the ridge vent that is at the top peak of your roof. It’s very efficient at allowing excess warm air to escape. The ridge vent works together great with soffit ventilation to provide the perfect combination of ventilation needed for proper air circulation. Older homes usually will not have a ridge vent, and many will not even have the soffit style of ventilation. As we discussed above, this will cause problems over time with your attic and roof structure.
You might be able to install new ventilation on your older roof. But, a review from a roofing professional is going to be your best next step. They will be able to guide you regarding proper ventilation options and whether a poorly ventilated roof needs repairs or replacement. Improper roof vent installation can be upgraded with a new roof to give superior circulation and increase the dependability of your roof and home.
