Roofing Dallas Texas Ventilation Requirements

By Eugenia Dickerson


Your roofing Dallas Texas is an important part of your home and care should be taken when making decisions regarding it. An important aspect of the design of the roof of your home is that it provides adequate ventilation. Inadequate ventilation can lead to the accumulation of moisture which will cause damage to the deck of the roof. Inadequate roof ventilation could be detrimental to the health of you and your family.

In roofing, the standard requirement for ventilation is a square foot of incoming to a square foot of outgoing ventilation. This is based on 300 square feet of attic space. This applies if vapor barrier insulation has been applied. If the insulation was done without a vapor barrier, the requirement should be doubled.

There are several reasons why a roof should be ventilated. Adequate ventilation will make the area in the attic cooler. Your home will become energy efficient which could save you a lot of money. It reduces the risk of fire in the roof. It stops condensation and moisture accumulation on the inner section of the roof deck which prevents the wood from rotting.

If you decided to go the route of hiring a roofing Dallas Texas company to consult on ventilation, you will be offered a range of vent types. Roofers will offer you roof ridge vents which are normally placed on the ridge line of your home's roof. Ridge vents are suitable for the outflow of heat, stale air and moisture. Eaves and soft fit vents are normally placed at the lower edge of the roof. It is suitable for the inflow of air.

In days gone by, many homes were not as tightly sealed as the newer houses are. There were often openings around the doors and windows, and possibly cracks as well. These opening and cracks allowed air to flow to the interior of the home. Since hot air rises, the moisture and heat that accumulated inside the home would rise towards the attic of the home and exit through the roof vents.

If there is inadequate ventilation in your roof, the moisture that rises into the attic with the warm air would form condensation and settle on the inner sections of the roof decking. The moisture in the house comes from cooking, laundry, bathing and other actions. Once the condensation settles on the roof deck, it will cause the wood to rot.

This not only damages the wood, but also releases mold spores into the air that you and your family breathe in. If this problem is not detected and taken care of, the wood forming the roof deck could collapse due to rot and the air inside your home will become unhealthy.

Once damage has been caused to the deck of the roof, it could cause the shingles to move because the wood will move due to rot. This may result in roof leaks which will require the attention of a roofing Dallas Texas consultant to help with repairs. As can be noted, adequate roof ventilation should be a priority. You should ensure that your roof has suitable ventilation and if it does not, take the necessary steps to immediately resolve this problem.
