Proper Attic Ventilation Is A Delicate Balancing Act.
Unfortunately, Most Roofers Are Too Heavy-Handed.
Attic ventilation is one of the most important elements of any roofing system. Unfortunately, it’s also the one thing that McDonough-area roofing companies get wrong the most.
Attic ventilation is a critical component of not just your roofing system, but your overall home. A badly vented attic can cause serious damage and sky-high energy bills. It can also lead to mold growth, rot, shingle failure due to overheating, and ice-dam formation.
The logical question to ask is “If attic ventilation is so important, why do so many roofers get it wrong?”
Before we answer that, we have to talk about how to do attic ventilation RIGHT.
The key to proper attic ventilation is an optimized ratio of intake ventilation to exhaust ventilation. The U.S. Federal Housing Administration (FHA) recommends one square foot of attic ventilation for every 300 square feet of an attic. Each square foot of attic ventilation must strike the right balance between intake and exhaust to ensure satisfactory airflow.
Two Ways Roofers Get Attic Ventilation Wrong
Your attic is a unique size and shape; therefore, your ventilation requirements are also unique.
Many roofers don’t consider this. Instead of customizing a ventilation solution, they use a “one-size-fits-all” approach. That is, they use the same type and size of ventilation for every home… and that can result in huge problems for their customers.
This is especially true if the roofer isn’t considering intake-to-exhaust ratios. The imbalance can cause a few issues, depending on how the ventilation system is set up…
- Negative air space is created when there is more exhaust than intake. What that means is your attic basically sucks up the conditioned air in your home through unsealing openings like vents, recessed lighting fixtures, and so on. As a result, your air conditioner must run constantly to compensate.
- If a roofing company installs two exhaust systems instead of an intake-exhaust system, the stronger exhaust system will pull air from the weaker one. This can result in some areas of your attic remaining unventilated.
How To Ensure Proper Attic Ventilation In McDonough
Bottom line: There is no “one-size-fits-all” attic ventilation system. Every home is different, so every home has different ventilation needs.
That’s why it’s critical to hire a roofing company that does attic ventilation right. And determining whether they do is pretty simple.
First, make sure the roofer performs an attic inspection when giving you a quote. They can’t possibly know your ventilation needs otherwise.
After they perform the attic inspection, ask them the following:
- Do you adhere to the FHA’s recommendation of one square foot of attic ventilation for every 300 square feet of attic?
- What is your plan to ensure a proper balance of intake and exhaust ventilation?
- Do you intend to install more than one type of exhaust ventilation? (If they say “yes,” run away!)
Posing these questions to roofers will weed out the ones who get attic ventilation wrong… and help you determine the ones who get it RIGHT.
