Do Mobile Homes Need Roof Vents? (Solved)

It does not matter the prevailing climate in the environment where the mobile home will be located, you will need roof vents in your mobile home for a variety of reasons, the attic of mobile homes, which is the space found directly below the pitched roof of a house, is an essential space to control the temperature of the house in a natural way and this can be achieved through the circulation of air in that space.

A roof vent in a mobile home with an attic will help keep the attic cool and ventilated during the summer and will keep the mobile home free of moisture during winter months, this has several advantages, aside from keeping the attic temperature down, it can mitigate mold and many other problems caused by lack of ventilation in a hot, enclosed space.

Ventilation in a mobile home is composed of two essential parts, apart from the roof vents, an effective side ventilation system is required, which can be through the fascia, or ventilation through the soffit.

Because the ventilation in the roof of a mobile home works by convection, that is, warm air tends to rise, some mobile homes ventilate the attic through a small space in the fascia that protrudes slightly from the eaves of the roof.

Many mobile homes do not have roof overhangs, in mobile homes that do have roof overhangs this method of ventilation can be made more efficient by adding ventilation through the soffit, for this, you can get some perforated vinyl or aluminum panels that are placed and ventilate towards the top of the roof where the roof vents are.

Do roof vents help prevent mold in a mobile home?

Of course, roof ventilators help mitigate the creation of mold in the attic and other spaces or corners of the house that could contain a lot of moisture. Mold is formed by an excessive accumulation of moisture, mainly in spaces where the humidity exceeds 50%.

There are several methods to prevent or control the appearance of mold in a house, and ventilation is the main aspect to control this problem, that is why ceiling fans are a fundamental element to prevent mold formation.

Renewing the indoor air inside the mobile home through ceiling fans also helps to reduce the rate of other potential indoor pollutants such as VOCs, CO2, and formaldehyde.

A mobile home without roof vents is only a matter of time before mold starts to appear.

Are mobile homes hot in summer?

Due to the materials and coatings, mobile homes can be hot in summer if they receive direct sunlight. Although the walls of the mobile home are protected by an insulating material, induction heat can also be generated through the roof and window panes.

The heat in a mobile home is more easily produced on the roof, since it is the part that will receive the most direct sunlight, although the heat could be mitigated with good ventilation, otherwise, if there is no ventilation, or the ventilation of the house is poor, logically the thermal sensation inside the house will be much higher.

Of course, the heat could be mitigated by technological means, such as air conditioning installed in the house, but the more effort the air conditioner has to make to cool the house, the more energy expenditure it entails and this represents a higher cost in the electricity bill.

do mobile homes have attic vents?

roof vents on the roof of a mobile home

The attic of a house should always be ventilated, but in reality, mobile homes have a very narrow attic space between the roof and the ceiling, that attic space is enough to store some things and to ventilate the mobile home, however, to answer the question, many mobile home models do not contain a vent in the space that is considered as the attic, especially the older models.

Instead, many mobile home models contain side vents, as explained at the beginning of the topic through the fascia in the roof overhang. In addition to having additional ventilation in the roof, mobile homes may have ridge vents in the roof instead of roof vents.

How many vents does a mobile home need in the roof?

According to the HUD ventilation code for mobile homes, in order to have proper ventilation, for every 300 square feet of living space in the house you will need to have one square foot of ventilation space, combining both roof and soffit ventilation.

Can you put a ridge vent on a manufactured home?

Ridge vents are one of the most popular forms of ventilation used in mobile homes, yes, you can put ridge vents in a mobile home or manufactured home, this type of system is widely used by many mobile home manufacturers, although other people do not like this ventilation system because it may be more susceptible to moisture intrusion.

Ridge vents are seamless vents that are placed at the ridge of a pitched roof. Roof ridge vents usually have cap shingles so that the vent is almost invisible from the ground.

Adding a roof vent to the mobile home roof DIY

Step 1: Get dumpsters

For this project, you will need to get a dumpster, either rented or borrowed, this is for throwing away old roofing materials.

Be sure to place the dumpster in an area of the yard or an area where it won’t be in the way, place a tarp underneath to make it easier for you to pick up any debris that falls out of the dumpster during the job.

Step 2: Climbing onto the roof

You will need a ladder tall enough to be able to climb onto the roof easily to remove the existing shingles. Don’t worry, the roof of the mobile home will hold the weight of one or more people without any problems unless you have badly rotted parts of the roof.

The ladder should be checked to make sure it is durable enough to support your weight and perform this task.

Climb the ladder, and try to have a helper for the job who will help you by passing you the necessary materials to remove the shingles once you are on top.

Step 3: Remove the roof

To remove the shingles you can use either a shovel or a pickaxe. Work carefully around the edge of the roof to avoid injury or injury. You should wear safety glasses while working, as a lot of loose material will fly off toward you. The material should be thrown in a garbage can below you as you work.

Step 4: Remove all nails and loose materials.

You must kneel down to remove loose nails and other materials left on the roof. This is a tedious, time-consuming process that requires you to carefully go over every inch of the roof. Throw the loose material in the dumpster.

Step 5: insert the tar paper

Spread the tar paper on the roof. This acts as a barrier to prevent water from seeping through the roof. The tar paper is attached to the roof with a stapler.

Step 6: Attach roof shingles and vent

Attach the roof shingles in rows. The shingles should have a flange or attachment that you can use to nail them to a nail strip that you installed over the tar paper. Work carefully to secure the entire row before moving on to the next row.

Use expanding foam to attach and seal the vent and other roof elements to complete this project.

If you want to do a much more precise job you can use a small crowbar instead of a shovel, a cutter and also the always useful hammer to remove the nails.
