Roofing Ventilation: Questions to Ask Roofing Companies in Baton Rouge

POSTED ON: November 1, 2021

Louisiana is known for exceptionally humid and hot summers. This makes roofing ventilation a crucial part of your roof’s health and longevity, as well as providing many other benefits. While keeping your attic cooler during warmer months is what most people associate roof ventilation with, many roofing companies in Baton Rouge, LA can inform you of their many other benefits: such as lowering energy costs, reducing damage to shingles, and providing adequate airflow to reduce attic moisture. Roofing ventilation lowers the temperature of your attic space, meaning your heating and cooling don’t have to work as hard to produce the same results. Because of the cooler temperature in the attic, roofing shingles aren’t susceptible to the high temperatures of an unvented attic space, which can cause shingles to deteriorate faster than they should. Proper air flow in the attic prevents mold and mildew from forming by expelling moisture, especially in a state like Louisiana.

If you’re about to replace your roof, or you’re building a new home, there are some questions you may need to ask your roofing company in Baton Rouge, LA.

How many roof vents is enough?

The general rule of thumb is one square foot of roofing ventilation for every 300 square feet of ceiling space. If your home has a vapor barrier, the roofing ventilation requirement doubles to one square foot of ventilation for every 150 square feet of ceiling space. Half of your roof vents should be set to air intake, and half to air exhaust.

What type of roof vents are there, and what do I need?

Your roofing company in Baton Rouge, LA will determine what kind of ventilation is appropriate for your home. There are many different types, from wind turbine ventilation to ridge ventilation to soffit ventilation. Whichever kind your roofing contractor in Baton Rouge, LA decides is appropriate for your home, there are no cons to having adequate roofing ventilation in Baton Rouge, LA.
