Signs a Roof Isn’t Properly Ventilated
A poorly ventilated roof has low-quality insulation. The longer it wreaks havoc on the roof, the greater the risk of delamination.
When maintaining their roofs, most homeowners notice sagging shingles or discoloration. There’s no way to effectively address the problem without understanding the cause. And in this case, the culprit normally lies in poor ventilation.
You can tell if a roof is badly ventilated by inspecting the structure for these five issues:
Loose or sagging shingles
A poorly ventilated roof has low-quality insulation. The longer it wreaks havoc on the roof, the greater the risk of delamination. In other words, some wooden parts of the unit become smooth, preventing the shingles from resting securely on top of them. Inevitably, these shingles come loose and can no longer protect the home properly.
Sagging shingles also accompany poor ventilation. Ventilation problems can weaken various elements of the roof. What happens in this case? You guessed it—the structure starts sinking and drags down any connected parts, including the shingles. That’s why sagging shingles are a tell-tale sign of inadequate ventilation.
Mold or discoloration
Few problems are as pressing as mold. Unfortunately, it can plague many homes, especially those with poorly ventilated roofs. Here’s why:
Bad ventilation limits airflow.
Instead of circulating, air remains in one place and attracts moisture.
Moisture allows mold to thrive.
The easiest way to spot mold is to look for blue-green spots on beams and other wooden components. It also generates an overpowering smell that may make the problem even more pronounced to owners.
The discoloration is another hallmark of improper ventilation. It normally appears as black stains in the attic and is caused by limited airflow.
Inefficient HVAC system
The HVAC system is the cornerstone of indoor comfort. It keeps the place cool in summer by distributing cool air throughout the house. In winter, it warms up the property with heated air.
However, don’t forget that an HVAC unit requires proper airflow to function correctly. Good circulation in individual rooms is essential, but roof airflow is just as important. Consequently, look for higher energy bills, pointing to lower HVAC inefficiency due to poor roof ventilation. Critters
Some properties have too much ventilation, especially when the roof has a hole or two. Besides lowering HVAC efficiency, these openings invite rats, birds, insects, and other unwanted critters. Homeowners who notice these creatures should contact a licensed roofer to confirm and patch up the ventilation issue.
Peeling paint
If there’s peeling paint in the attic, it could mean that the roof isn’t ventilated properly. The room traps too much moisture, resulting in peeling or blistering paint.
Contact a trusted roofer
There’s no other way around it—the only reliable way to verify and fix ventilation issues is to partner with a licensed roofer. Contact them, describe the signs you’ve noticed, and they’ll use all their expertise and tools to solve the issue.
