Houses need adequate ventilation to ensure living spaces have the proper humidity levels for comfort and air quality. However, many Florida homes lack necessary roof ventilation, leading to severe roofing system deterioration and other costly problems. Below, you can learn the signs of poor ventilation in houses, so you know when to take proper action.
1. Mold Growth
Natural ventilation from open windows isn’t always enough to keep moisture levels low. It’s not uncommon for poorly ventilated attics to trap warm air, making the environment ideal for mold growth.
The proper attic ventilation options allow sufficient air to circulate through the room. The constant exchange of air helps prevent the attic from becoming humid enough to promote mold growth.
2. Attic Discoloration
One of the more obvious signs of poor ventilation in houses is attic discoloration. Though discoloration might mimic mold’s dark, spotty appearance, it is more problematic to the roofing system than your health. If you allow the black stains to spread, you could need total roof replacement earlier than expected.
3. Heating and Cooling Issues
Your roof’s ventilation system improves your heating and cooling units’ efficiency. For instance, some parts of the house might feel cooler than others despite the air conditioning running frequently. The problem comes from the home’s reduced airflow due to the roof’s lack of intake and exhaust vents.
Improperly sized HVAC units can also contribute to inconsistent heating and cooling. However, if your AC and furnace are in good shape but the problem persists, the issue could be insufficient roof ventilation.
4. Poor Indoor Air Quality
Indoor pollution levels can be higher than levels outdoors due to several factors, including emissions from cooking, air fresheners, scented candles, and household cleaning chemicals. However, poor attic ventilation can increase indoor pollutant concentration because the house isn’t circulating enough outdoor air to dilute airborne contaminants.
5. Damaged Roof Shingles
Asphalt roofs should last for a couple of decades with proper installation and routine maintenance. However, premature roofing material degrading could indicate a lack of ventilation over the roof’s surface.
Take note of asphalt shingles that are cracked, buckling, or warping. The damage could be due to excessive roof surface temperature and trapped moisture. Both problems require proper ventilation.
How Many Roof Vents Do I Need?
Roof ventilation is a system of vents that draws air into the building and allows indoor air to seep out. The air circulation of the vents helps the home stay comfortable while keeping moisture levels low.
You might ask, “How many roof vents do I need?” To find the answer, use the standard formula for roof ventilation systems: one square foot of ventilation for every 150 square feet of attic space.
