Boost Your Kitchen's Air Quality with a Roof Mounted Exhaust Fan
Whether you're an avid home cook or simply like to whip up the occasional meal, it's likely that your kitchen could benefit from improved ventilation. Steam, grease, smoke, and strong cooking odors can quickly make the air in your kitchen feel heavy and unpleasant. Installing a roof mounted kitchen exhaust fan is an excellent way to clear the air and make your kitchen more comfortable.
Roof mounted kitchen exhaust fans are designed to efficiently remove contaminated kitchen air and humidity. They are mounted on the roof with ductwork that vents outdoors, helping prevent grease buildup and odor accumulation in your home. Let's explore the benefits of a roof mounted exhaust fan and key considerations when choosing and installing the right model for your needs.
Why a Roof Mounted Exhaust Fan Improves Kitchen Air Quality
Roof mounted kitchen exhaust fans enhance indoor air quality in several important ways:
- They rapidly remove cooking pollutants like grease, smoke, fumes, and odors, preventing them from spreading throughout your home.
- They reduce humidity and moisture buildup caused by cooking, which helps control mold and mildew.
- They bring in fresh outdoor air, replacing stale or stuffy kitchen air.
- They prevent grease buildup on kitchen walls, cabinets, and surfaces by venting contaminants outside.
By clearing away airborne cooking pollutants, a powerful roof mounted exhaust fan keeps your kitchen environment cleaner and more pleasant to be in, even during extended cooking sessions. You'll also enjoy health benefits from improved indoor air quality.
Reducing Cooking Odors and Humidity
Roof mounted kitchen exhaust fans are highly effective at reducing cooking odors. Rather than recirculating contaminated kitchen air like some under-cabinet models, roof mounted fans directly exhaust odors outdoors. This keeps your entire home free of lingering cooking smells.
These fans also actively lower humidity caused by cooking moisture and steam. Excess humidity can encourage mold growth and cause cabinetry and surfaces to deteriorate over time. A roof mounted exhaust fan maintains optimal indoor humidity levels.
Preventing Grease Buildup and Promoting Cleanliness
Venting cooking grease and residues outside prevents grease accumulation on kitchen surfaces. Over time, grease residues become grimy and difficult to clean. A roof mounted exhaust fan keeps your kitchen cleaner and easier to maintain.
By removing airborne contaminants, roof mounted exhaust fans also help keep the rest of your home's ductwork and surfaces cleaner. This improves overall indoor air quality and protects your investment in your home.
Choosing the Right Roof Mounted Exhaust Fan
When selecting a roof mounted kitchen exhaust fan, key factors to consider include:
CFM Rating
The CFM (cubic feet per minute) rating indicates the airflow capacity of the fan. A higher CFM moves more kitchen air, so it's better for larger or commercial-grade cooking setups. For home kitchens, look for a CFM between 300-600 matched to your kitchen's size.
Fan Speeds
Multiple fan speeds give you flexibility. A high speed clears cooking smoke and odors quickly, while a low speed prevents humidity buildup during routine cooking. Look for at least 2-3 speeds.
Noise Level
Roof mounted fans are typically quieter than under-cabinet models since they're located far from the kitchen. Look for units with sound levels around 6.5 sones or less.
Automatic Shutoff
An automatic shutoff uses a timer or sensor to turn the fan off after a preset duration. This prevents the fan from running unnecessarily and helps reduce energy costs.
Indicator Lights
Indicator lights are a useful feature that let you know when the fan is actively venting air. They remind you to turn it off after cooking.
Removable Grease Filters
Removable grease filters simplify maintenance by making the filters easy to access and clean. Models with dishwasher-safe filters offer added convenience.
Professional Installation for Optimal Performance
Due to the ductwork modifications and potential electrical work involved, professional installation is recommended for roof mounted kitchen exhaust fans. This helps ensure your system is:
- Properly vented through the roof
- Wired correctly by a licensed electrician
- Compliant with local building codes
- Operating at maximum efficiency
The installer will determine the optimal ductwork route to minimize bends, preferably venting upward through the roof near the kitchen. Correct duct sizing is crucial for proper airflow.
Key Installation Considerations
If installing the exhaust fan yourself, key steps include:
- Cutting openings for ductwork routes
- Mounting and securing ductwork
- Installing a roof cap that prevents backdrafts
- Securing the fan unit and making wiring connections
- Testing for leaks and verifying adequate airflow
Avoid extensive duct elbows or horizontal runs which can hinder airflow. Also ensure ducting is properly sealed and secured.
Maintaining Peak Performance
Like any effective exhaust system, roof mounted kitchen fans require periodic maintenance. It's important to:
- Clean fan blades and removable grease filters regularly
- Inspect ductwork for accumulated grease or blockages
- Check for leaks around mounting points or duct joints
- Verify the roof vent cap opens properly
- Replace charcoal filters on ductless models when needed
- Service the fan motor as recommended by the manufacturer
Taking steps to keep your roof mounted exhaust fan well-maintained ensures it continues removing airborne pollutants as effectively as the day it was installed.
The costs to install a roof mounted kitchen exhaust fan depend on the unit CFM, features, ducting complexity, and professional installation fees. While installing a powerful exhaust fan represents an investment, the benefits of greatly improved indoor air quality and kitchen comfort are worthwhile.
By effectively capturing and venting cooking pollutants outdoors, a roof mounted exhaust fan provides fresher, cleaner air that enhances the kitchen experience. Your home and family will enjoy the rewards of reduced odors, grease, and humidity for years to come.
