Appropriate roof ventilation is undoubtedly a factor to consider when purchasing a house, as it determines its efficiency and life expectancy. If you have a double-wide home and want to install ventilation but are wondering how to do so, this post is for you. We searched and asked professionals, and we found these answers.
A double-wide roof ventilation system must have two parts: intake vents and exhaust vents. A ridge vent is the most suitable for handling a double-wide roof pitch, among other roof vents. This type of vent is best for extending the life of your roof.
The ridge vent (exhaust) works by installing soffit vents (intake) on each side of the roof. The combination of both ridge vents and soffit vents creates a proper double-wide roof ventilation system, though some factors require consideration to achieve the best ventilation for a double-wide roof.
As you have read, venting a roof is not easy, as installing a mechanical device to permit the circulation or air inside the house requires expertise. Continue reading to learn how to install a double-wide roof vent successfully.
Double-Wide Roof Ventilation Tips
A proper ventilation system is necessary for a double-wide home like any other traditional home. Having proper ventilation will surely boost the performance of these homes. Here are some of the ventilation tips for a double-wide roof:
- Provide a minimum of 1:300 of the total roof cavity area for free ventilation.
- Half of the required ventilated area is allotted for the upper ventilators.
- The remaining half is apportioned for installing the soffit or eave vents.
- Vent openings and ventilators should be placed to provide a passageway of air in the whole roof cavity area.
- There should be a clearance of one inch between the roof cover and the insulation material to provide a direct airflow.
- Alternatively, install a mechanical ventilation system that can provide ample air in the roof cavity area, provided that intake and exhaust vents must also be present.
- The vents should withstand underlying weather conditions and can restrain the entry of birds and insects.
What Are the Two Components of a Roof Ventilation System?
A typical ventilation system is composed of both intake and exhaust vents. These two are very important in regulating humidity in your entire house. Here are the types of commonly used vents:
Intake vents are placed at the lowest possible eaves of the roof and must be near soffits. This vent permits outdoor air to enter the roof cavity, thus regulating the humidity level inside the house. The roof intake vents are eave vents, soffit vents, and fascia vents.

Exhaust vents are employed to extract warm air from inside the house and force it outside. This roof vent is mainly set at the highest possible portion of a roof. The most efficient exhaust vent is the ridge vent.

Why Are Roof Vents Needed On Manufactured Homes?
Roof ventilation has a great impact on the quality of life inside a house. Without proper roof ventilation, warm air is trapped inside the house and can cause unexpected repairs due to humidity.
Ventilation is essential because it helps keep your roof in excellent condition for an extended period, can save energy, and neutralizes room temperature. The following are the upsides of having a roof ventilation system:
Roof ventilation protects the roof shingles from cracking and blistering. Also, roof ventilation secures your ceiling from mold and deterioration.
Bad weather is inevitable, but its aftermath is manageable. Hurricanes, rain, and snow can cause damage to your roofing over time. However, ventilation averts the aftereffects from happening.

Ease of Repair and Maintenance
The roof vent is a doorway between the roof and ceiling and is advantageous to future repairs and maintenance. The need to secure and inspect roof vents like gable, ridge, and soffit vents performance from time to time.

When selecting roofing assemblies, there are various types of materials to choose from. However, you must also understand the material's properties and the underlying weather conditions. This section presents the leading roof coverings suitable for double-wide roofs.
GI corrugated sheet is a covering material commonly used to construct temporary shelters. It is made of galvanized metal and is available in different sizes.
