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:

  1. Provide a minimum of 1:300 of the total roof cavity area for free ventilation.
  2. Half of the required ventilated area is allotted for the upper ventilators.
  3. The remaining half is apportioned for installing the soffit or eave vents.
  4. Vent openings and ventilators should be placed to provide a passageway of air in the whole roof cavity area.
  5. There should be a clearance of one inch between the roof cover and the insulation material to provide a direct airflow.
  6. 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.
  7. 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?

Intake 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.
