A Ventilated Roof is a Healthy Roof
Victory Home Remodeling is among the premier residential roofing contractors in New Jersey. Our company offers a full range of roofing services, including ridge vent installation. One of the most common questions we get from our customers is whether or not they need to replace their ridge vents when they have their homes re-roofed. While the answer does depend on a number of factors, we generally recommend it as roof replacement is the most practical and affordable time to do it. If you need to have ridge vents replaced years down the line, the job is going to be significantly more expensive then.
The reason ridge vent installation is so important is that it allows air in the attic to circulate. In other words, the air in the attic can normalize with the outdoor air, which means that the attic never gets too hot or too cold. A hot attic is problematic because the shingles withstand hotter temperatures that cause the material to break down faster. Poor air circulation in an attic can lead to ice dams in winter as well. It also makes the home more difficult to heat in winter and cool in summer. A home will be less comfortable without proper attic ventilation, and your energy costs will be higher too.
Improve Your Home's Energy Efficiency
Proper ridge vent installation plays an integral role in a building envelope, and that envelope dictates how energy efficient a home is. The ideal temperature for an attic is no lower than 60°F in winter and between 10 and 20 degrees higher than the outdoor temperature in summer. If your attic gets hotter than that, the air in your home will be more humid, and it will require more energy to cool it to a temperature that you find comfortable. Likewise, if your attic gets colder than 60°F in winter, it will require a lot more energy to heat your home to a comfortable level.
Install a Roof Vent During Your Roof Replacement
The easiest time to perform ridge vent installation is when having your roof replaced. During a roof installation, all of the required ancillary work has to be done anyway. Therefore, the cost will be lower. This is why roofing contractors generally recommend replacing roof vents when reroofing regardless of the condition of the existing vents and why many warranties require it as well. If you wait and need them replaced later, it’s going to be a hassle and more expensive, and if you procrastinate, you’re going to end up losing money because the inadequate attic ventilation is going to cause your shingles to wear out faster. The industry estimate is that poor roof ventilation decreases shingle lifespan by 24%.
