Older homes, as well as new construction, have one thing in common – a lack of ventilation to the roof surface.
Lack of ventilation in turn means they have inadequate air movement and they typically have either too few vents or the vents they have are not functioning properly.
You must have adequate roof ventilation in your home, especially in Texas where the surface temperature of a roof can reach excesses of 170 degrees Fahrenheit. Without this feature on your roof, you will see premature aging of your shingle, expedited granular loss, thermal cracking, heat blisters, and excessive nail pops.
Other benefits that come along with a properly ventilated roof:
1. Proper ventilation can help balance the temperature of your home.
When you have a new home built, or you’re replacing a roof, then installing proper ventilation helps to balance out the transfer of hot and cold air.
During the summer months, your attic and upstairs will always have higher temperatures, regardless of how strong your air condition systems are, because of how the hot air rises. However, when there are vents installed in the roof, the hot air is allowed to escape the home naturally, which in turn helps balance the temperatures below.
In the evening and during winter months, this ventilation allows the pressure of the cold air outside to prevent all the warm inside air from escaping. This process can allow a homeowner to save more on utilities each month, whether during summer months or winter months.
2. Ridge vents can add aesthetic appeal to your home
Ridge vents offer a sleek design that is difficult to notice from ground level. The pitch of your structure remains unaffected by the design of the ridge vent.
If you have enough intake from your soffit, it is possible to install them along every ridge of your roof, which provides your home with the maximum level of ventilation. The amount of ridge vent we install to the roof actually depends on the square footage of attic space, which is measured before we began work on the project.
The above are just a couple of the reasons why it is worth making sure your roof contractor considers your roof ventilation system.
The next time you have work done on your roof, be sure to ask your contractor about this! We're sure you'll be glad you did.
