Understanding Ridge Vents and Manufactured Homes
If you own a manufactured home, attic ventilation might not be your first concern—until you start noticing potential problems like excessive heat, moisture, or even mold. Many homeowners wonder: Can you install a ridge vent on a manufactured home? The answer is: Yes, but with important caveats and considerations.
Let’s break down everything you need to know before deciding whether a ridge vent is the right fit for your manufactured home.
What Is a Ridge Vent?
A ridge vent is a type of passive attic ventilation installed at the peak (ridge) of a sloped roof. This vent runs horizontally along the roof’s main spine, allowing hot, humid air to escape and encouraging fresh air to flow up from lower vents (such as soffit or gable vents). This “passive” system works without electricity, relying on natural airflow.
Unique Roofing Structure of Manufactured Homes
Manufactured homes aren’t built exactly like site-built houses. Their roof construction often includes:
- A relatively low roof pitch (less of a slope).
- Engineered truss systems.
- Metal or shingle roofing, sometimes installed over solid sheathing, sometimes not.
- Factory-installed roof and attic ventilation features.
This means that altering or adding new venting systems, such as a ridge vent, isn’t always straightforward and requires careful consideration.
Is a Ridge Vent Suitable for My Manufactured Home?
Key Factors You Must Evaluate
- Type of Roof Construction
- If your manufactured home has a traditional, stick-built-style roof with adequate attic space and a ridge, installing a ridge vent may be possible.
-
If your home has a “roof-over” (additional roof built over the original), or low attic space with no continuous ridge, installing a ridge vent may not work.
-
Existing Ventilation
- Factory-built homes often come with specific venting (like gable or roof vents) as per HUD standards.
-
Adding a ridge vent to an already well-ventilated space could disrupt airflow or make little difference.
-
Attic Cavity Size
- Ridge vents require a “flow” of air: hot air must exit at the ridge while cooler air enters through soffit or eave vents.
-
Very shallow or non-ventilated attics might not benefit from a ridge vent at all.
-
Roofing Material
- Shingle roofs make ridge vent installation much cleaner and simpler.
- Metal roofs may require special ridge vent products (not all are compatible).
Ridge Vent Benefits in Manufactured Homes
If installed correctly and in the right roofing system, ridge vents provide several advantages:
- Improved Airflow: Reduces heat and moisture buildup, making your home more comfortable in summer and reducing the risk of condensation in winter.
- Energy Efficiency: Better attic ventilation means less strain on your HVAC system, potentially lowering cooling costs.
- Prevents Mold and Damage: Moisture in attic spaces can lead to wood rot, mold, and damaged insulation.
- Low Maintenance: Ridge vents have no moving parts and, when properly screened, don’t clog easily.
Challenges and Limitations
While the benefits are appealing, you should be aware of some challenges:
- Structural Compatibility: Many manufactured homes have limited attic space or use a “cathedral” ceiling, making ridge vent installation impractical.
- Roof Shape: A flat or slightly sloped roof may not provide enough rise for a ridge vent to work effectively.
- Water Leaks: Improper installation can result in leaks, especially on low-pitched roofs.
- Cost vs. Gain: If your roof is not compatible or your attic isn’t ventilated (or is non-existent), installing a ridge vent may offer little benefit.
Steps to Add a Ridge Vent to a Manufactured Home
If you determine your home may be suitable for a ridge vent, here are the basic steps involved:
- Assess Existing Ventilation
- Calculate attic square footage and inspect current vents (soffit, gable, turtle, etc.).
-
Determine if your home meets ventilation codes and if a ridge vent will add balance.
-
Pick the Right Ridge Vent
- Choose a vent designed for your roofing material (shingle or metal).
-
For metal roofs, look for specialized manufactured home compatible models.
-
Measure and Plan
- Accurately measure the attic space and ridge length.
- Ensure there is adequate intake (soffit) venting to complement the exhaust (ridge).
- Roof Preparation
- Carefully remove a strip of roofing along the ridge, exposing the sheathing.
-
Cut a gap along the peak per manufacturer’s guidelines.
-
Install the Ridge Vent
- Attach the vent system as per instructions, making sure it is waterproofed and sealed.
-
Replace or adapt roofing materials as needed.
-
Check and Test
- Inspect for leaks or drafts after a rainstorm.
- Monitor attic temperatures and humidity to confirm ventilation improvement.
Tip: Professional installation is highly recommended for manufactured homes due to unique construction and warranty concerns.
Alternative Ventilation Options
If a ridge vent isn’t suitable for your manufactured home, don’t worry—there are other effective options!
Common Alternatives
- Gable Vents: Installed on the gable ends of your home, these are excellent for shallower attic spaces.
- Roof Vents (Turtle Vents): Small, louvered vents added at intervals across the roof.
- Whirlybird (Turbine) Vents: Vents that spin with the wind to pull hot air out of the attic.
- Soffit Vents: Must be paired with adequate exhaust vents for balanced airflow.
- Powered Ventilators: Fans installed in the attic or roof, best used where passive ventilation is insufficient.
Best Practices and Practical Tips
For the best result in ventilating your manufactured home, keep these tips in mind:
- Balance Intake and Exhaust: Always pair roof/ridge vents with proper soffit or gable venting. Exhaust without intake limits performance.
- Comply With Codes: Follow HUD and local building codes. Inadequate or improper ventilation can void warranties or even insurance policies.
- Prevent Pests: Use vent screens to prevent birds, insects, and rodents from entering.
- Check Insulation: Good attic ventilation works best with proper insulation. Avoid blocking vents with insulation material.
- Regular Inspection: Inspect vents annually for debris, blockages, and wear.
Summary
A ridge vent can be a great addition to some manufactured homes, especially those with conventional attic and roof construction. However, many manufactured homes have unique limitations that make ridge vent installation unnecessary, impractical, or even impossible. Always evaluate your home’s roof type, attic structure, and existing ventilation before making changes. If in doubt, consult a contractor experienced with manufactured homes to explore your best ventilation options.
Frequently Asked Questions (FAQs)
1. Can all manufactured homes have ridge vents installed?
Not all manufactured homes are suitable for ridge vents. The roof structure, slope, and attic design must allow for airflow from soffit to ridge and have a continuous ridge line. Many manufactured homes with low-pitch or flat roofs aren’t ideal candidates.
2. Will a ridge vent improve my manufactured home’s energy efficiency?
If your attic is poorly ventilated, adding a ridge vent (with proper intake vents) can help regulate attic temperatures and may reduce the strain on your HVAC system, especially in summer. However, if your existing ventilation is already balanced, the improvement may be minimal.
3. Is it necessary to have other vents if I install a ridge vent?
Yes, a ridge vent should always be paired with intake vents, such as soffit vents. Without an intake source, the ridge vent can’t effectively draw out stale air, which defeats the purpose of installation.
4. Are there any risks to adding a ridge vent to a manufactured home?
Improper installation can lead to leaks, structural damage, or ineffective ventilation. Because manufactured homes have different construction than site-built homes, always assess compatibility and consider hiring a qualified installer.
5. What should I do if my manufactured home can’t accommodate a ridge vent?
Many alternative venting solutions can keep your attic dry and cool. Gable vents, roof/turtle vents, and powered fans are viable options that may better suit the unique construction of manufactured homes. Always prioritize code compliance and balanced airflow.
With the right approach, you can ensure your manufactured home remains dry, comfortable, and energy efficient—whether you choose a ridge vent or another attic ventilation strategy.
