Manage Attic Heat and Moisture
Attic ventilation is essential to control airflow and temperature in your home. However, many attics have little or no ventilation, causing stale air, mold growth, and temperature dysregulation. With a properly installed attic exhaust fan, both cold and warm air can move through the structure more effectively, and keep the air fresh.
FixRoof can bring a blast of fresh air to your attic. We’ll position your fan to maximize heat transfer, we won’t compromise the framing (e.g. trusses), we’ll make sure all electrical connections are secure and up to code, and we’ll flash and seal the roof penetration so that the exhaust fan area doesn’t leak.
Get your attic exhaust fan working properly, stop leaks, and improve your attic space overall. Contact us today to learn more about attic exhaust fan installation and repair.
Why is Attic Ventilation Important?
A poorly ventilated attic can trap heat in your home during the summer, trap moisture in your attic, rob your living space of heat in the winter, cause ice dams to form on your roof, and drive up your utility bills year-round. Along the way, the poor ventilation can cause your roof to age prematurely, allow mold to grow and spread, damage anything you store in your attic, and make any trip up to your attic unpleasant or dangerous. A simple exhaust fan can help with all of that. There are several reasons attic ventilation is important, including:
Temperature problems
When air is trapped in the attic, it can make your home hotter in the summer as warm air collects and doesn’t ventilate, and colder in the winter as the warm air rises to your attic.
Mold
Proper airflow helps to prevent mold and mildew growth.
Ice Dams
Differences in temperature cause ice to thaw and refreeze across the roof, creating ice dams which can put your roofing system at risk.
Roof deterioration
Temperature changes can affect your roof throughout the year, causing roofing materials to wear out faster.
Keep Your Attic Air Moving
An attic exhaust fan can help improve the air quality in your home or business, improve temperature regulation, and more. Contact us today to learn more.
When Do You Need an Attic Exhaust Fan?
There are several issues that can indicate poor ventilation in your attic. Without adequate airflow, attic heat can reach extreme temperatures, which contributes to the premature aging and deterioration of roofing materials. An attic fan helps keep temperatures in check, extending the lifespan of your roof by preventing warping, cracking, and other heat-related damage.
Moisture buildup can also turn a poorly ventilated attic into a breeding ground for mold. Aspergillus, Cladosporium, and Stachybotrys (Black Mold) grow on wood, sheetrock, insulation, and in HVAC systems. Attic fans help reduce moisture levels, which can limit the conditions that allow mold to grow, helping to protect your home from potential health hazards.
Stale, hot air trapped in your attic can potentially affect your living areas, lowering indoor air quality. An attic fan helps to expel this air, promoting better airflow and contributing to a healthier living environment.
By lowering attic temperatures and reducing the workload on your HVAC system, an attic fan can improve your home’s energy efficiency. This can lead to savings on your energy bills.
Here are some signs you might need an attic exhaust fan:
Your home has a hot upper floor.
You have unusually high cooling bills.
You notice signs of moisture or mold in your attic.
Your attic gets much hotter than the temperature outside.
The attic smells stale or musty.
You often get ice dams.
Your attic lacks other ventilation: soffit vents, gable vents, a ridge vent, or open windows.
Finished Attics vs Unfinished Attics
Attic exhaust fans are not needed in every situation. Generally, finished attics usually have built-in ventilation systems that keep the internal temperature at a reasonable level. An exhaust fan may not be needed for a finished attic because of this existing airflow system.
Unfinished attics typically need exhaust fans, because these airflow systems don’t exist in unfinished attics. Unfinished attics tend to store unused items long-term, often including valuables. Without an exhaust fan, these items can be exposed to extreme heat and mold, leading to damage over time. Installing an attic fan helps keep the space cooler, protecting your stored belongings from getting cooked.
