Does Your Roof Have Proper Ventilation?

The last time you entered your attic to put away decorations, did you notice a musty smell? Did it seem excessively hot? Maybe you noticed that your energy bills crept up lately, or that there are indications of water leakage. These are just a few signs that your roof may not be adequately ventilated. In addition, if your asphalt shingled shelter does not have sufficient ventilation, the manufacturer’s warranty may be voided.

Determining if your roof has enough ventilation is a matter of understanding how much you need, doing some quick math, and using the right roofing supplies. Not all homeowners want to depend on themselves to make sure the structure is sound. Working with a trusted expert team like Century Roofing Limited can ease the confusion and ensure your home’s roof has the proper airflow without voiding your warranty.

How to Ensure Your Roof Has the Right Amount of Ventilation 
It is essential to know how much ventilation your roof needs and how to vent correctly. Here are a few steps to take into account:
• Calculate the Proper Amount of Ventilation – Understanding exactly how much ventilation you need is the first step in protecting your attic and roof. Building codes dictate what you are looking for. For example, if the code requires a ratio of 1/150 of ventilation space to attic floor, you would take the square footage of your attic and divide it by 150. Then you compare that figure to your overall ventilation. An experienced roofing contractor at Century Roofing Limited can make this complex task easier for you.

Choose the Best Products – There are a variety of options to help with proper ventilation. Here are a few:

  • Ridge Vent – A ridge vent is a ventilation strip that is installed along the ridge line of your home. To work correctly, a 1-inch wide piece of roof decking is removed along either side of the ridgeline. The ridge vent is then placed over the ridgeline.
  • Soffit Vents and Insulation Baffles – The key to any ventilation system is having a place of entry and exit for air flow. A soffit vent allows air to flow in and then up to the ridge vent. When you add insulation baffles at the point where the attic floor meets the roof line, you ensure that your insulation stays in place and does not block airflow via the soffit vents.
  • Powered Attic Fans – Sometimes called a whole house fan, attic fans can be installed in your roofing system to draw out the heated air from your attic. They may be controlled with a switch or thermostat. There are even solar powered options available.
  • Gable Vents – These louvered vents are placed in the gable end of your home and allow air into your attic while keeping the elements outside.
