It is for this very reason the Importance of Roof and Attic Ventilation might be worth learning about. Your wallet might thank you for it later!
The Importance of Roof and Attic Ventilation
How It WorksEffective Airflow in unfinished attics typically include:
- Intake Vents
- Exhaust Vents
These vents are used to permit constant airflow throughout the attic space.
If they work correctly, the cooler air will draw through the intake vents, and
the hot air will exit through the exhaust vents.
Why Should We Be Concerned about Roof Ventilation?
Simply put, hot air and humidity damages your home.
Appropriate ventilation
in your attic will ensure that hot air and humidity are removed.
Without roof
and attic ventilation, the warmth and humidity buildup no matter the climate.
3 Reasons to Ensure Sufficient Roof and Attic Ventilation
#1 Beat the Heat
Are you feeling heat down in your living areas during the summer? If so, your attic floor may not be insulated the way it should be.
During summer months, the sun causes an increase in attic temperature. The heat could actually distort roof sheathing and warp shingles. Hire a certified roofing professional in Pittsburgh to inspect the attic floor to see if it is evenly and properly insulated.
#2 Prevent Ice Damming
In Pittsburgh, average low winter temps drop to the 20s. We receive approximately 28 inches of snow during winter months. So, in similar locales, warm air will rise to your attic from the living spaces below (in homes without proper attic ventilation).
The roof deck will warm during the above process. If there is snow on the roof, it will melt, causing it to run down the roof. However, it will refreeze once it reaches the cooler outer edges.
Ultimately, this entire process causes ice damming due to the refreezing water. Ice dams prevent water from escaping, so it can back up underneath the shingles.
#3 – Get Rid of the Humidity
September is known to be the most humid month in Pittsburgh, PA, but the average humidity runs around 68%.
If your attic is cool: Over time, moisture from the humidity of your living areas causes condensation when it meets the colder surfaces of the attic. The condensation over time causes the roof structure to deteriorate, believe it or not.
If your attic is warm: The moisture from humidity causes mold and mildew.
Summertime is always a great time to learn the Importance of Roof and Attic Ventilation. But sometimes, finding a roofer you trust is difficult.
