How Does Insufficient Ventilation Cause Residential Roofs To Rot

May 10, 2022

Many house owners do not pay attention to the ventilation of the houses, which in turn results in the high electricity bills and rooting of the roof. Ventilation plays a very important role in the maintenance of the house and protects the roof from damage.

Most roofers say the roof’s ventilation provides a very noticeable decrease in the utility bills as it keeps the house warm in winters. If there is no proper ventilation in the house, it will reduce the roof’s life span. It is more likely to rot in a few years.

You have to invest a lot of extra money and effort in repairing the roof. Ventilation of the roof maintains a proper balance in the environment of the house. The areas that are more likely to be exposed to hazardous environmental conditions should have sufficient ventilation on the roof.

The industry standard for the roof’s ventilation is 1 square foot inside ventilation and 1 square foot outside. The importance of ventilation cannot be underestimated; it helps to keep the roof safe from excessive moisture that, in return, reduces the strength of the roof and many more.

Here are some of the damage to your roof if proper ventilation is not provided:

Insufficient ventilation

Insufficient ventilation involves a lot of issues like water leakage, loss of shingles, excessive water loss or excess moisture in the house, and extremely warm conditions in the summers. In short, if proper ventilation is not available in the house, it becomes an uncomfortable place to live in.

Shortened roof life

The roof life is shortened due to inadequate ventilation, the excess moisture absorption in the roof, the missing shingles, and continuous underlayment damage reduce the roof’s life span. Therefore, you have to take care of the roof maintenance on and off to resolve any minor issue on time and save yourself from future damage.

Rusting of the roof

The rusting of the roof is also one of the damages caused by improper ventilation. The moisture is absorbed in the roof as it does not find enough space to escape from the roof. Therefore, it will result in the rusting of the iron materials of the roof, like nails in the roofing.

The rusting reduces the strength of the roof. The long-term rusting results in the replacement of the roof.

Unwanted growth

Insufficient ventilation might also provide favorable conditions for the growth of unwanted plants. The unwanted growth may cause small gaps and whole production in the roof. In addition, there might be the growth of unwanted destructive pests like mice and termites in the gaps between the shingles, which reduces the roof’s strength.

The termites might eat the wood in the roofing and reduces its strength. Proper ventilation help in proper water evaporation, and there is no excessive moisture retained in the roof.

Importance of proper ventilation

Proper ventilation is very important to maintain the proper prime living conditions in the house. If there is no proper ventilation in the house during the summers, extremely warm air is trapped in the house and causes a lot of suffocation.

In countries that experience extreme weather conditions, it is very important to have proper ventilation to maintain its temperature. If proper ventilation is not provided, the hot air cause mold growth in the summers.

The ice dams are also the result of the poor ventilation in the winters.

Reduce the utility bills

The proper ventilation keeps the temperature of the house moderate. It keeps the temperature of the house balance. So do not worry about the high electricity power bills during the summer; the proper ventilation keeps the house cold, and you do not have to splurge on the air conditioners.

During the wintertime, the proper ventilation keeps the house warm and cozy and prevents ice dams; hence you can notice a remarkable bill reduction.

Many conditions like rusting, roof leaks, mold, ice dams, and missing shingles can be reduced through proper ventilation. The roof’s life span also increases through proper ventilation, and you do not have to invest money in it again and again.

Conclusion

The roof’s ventilation is a very important step that should not be neglected while constructing the house or any building. The ventilation process can be done naturally or mechanically according to feasibility. In extreme weather conditions, ventilation plays a very important role in keeping the temperature moderate. And it is the best way to eliminate the chance of mold growth in any house and building.
