Why Do You Need Efficient Roof Ventilation_

Last week we wrote about drip edges, but that left out a pretty large subject that’s just as important to the health of your roof. That topic is ventilation and why it’s essential for the health of your roof. Your home seems like it should be a closed system be more energy efficient and protect it from water and weather damage, but too closed can cause an array of additional problems. If your roof is buttoned up tight, you risk issues with dampness, mold, or air quality. So, the question isn’t why you need ventilation but rather how to improve your home’s ventilation before and when you get a new roof.

The High Cost of Poor Ventilation

It may not occur to you right away, but some of the high energy bills you’re seeing throughout the year are due to poor ventilation in your roofing. You may think that you can keep your home heated longer if warm air can’t escape through the roof, but that’s not precisely how that works. What happens in the summertime when your air conditioning is working hard to cool your home? Without proper ventilation, your attic temperatures may reach over 150 degrees inside, which doesn’t just create a cooling problem. It can also cause damage to your roofing.
When your attic rises to these outrageous temperatures in the summer, it can lead to condensation issues which will ruin shingles and encourage the growth of mildew or mold.
And, in the winter, the damage can be just as devastating. If your roof isn’t properly vented, you could risk ice damming on your roof which can damage not only your shingles but the very structure of your home.

The Health Risks in Your Home

When we mention the growth of mold and mildew, it isn’t just because it’s an inconvenience to homeowners. Rather, the extended growth of either type of insidious fungus can lead to long term problems if not dealt with right away.
Long term exposure to mold can exacerbate allergies and even cause asthma symptoms to worsen. And if your home is harboring black mold, the consequences can be dire. It may not be too late to sort out these problems, but it can never be too soon either. Addressing your ventilation can prevent further complications and provide a healthier environment for you and your family.

Ways to Improve Ventilation

There is good news. There are many ways you can improve your home’s overall ventilation without completely rebuilding your roof structure. You can start by adding exhaust fans in your kitchen and bathrooms. You can also install an attic vent if you don’t already have one.
There are also quick fixes such as opening doors and windows, and running ceiling fans or window fans. Even by opening windows in different areas of the home, you can create a cross breeze that can improve air quality.
Proper attic ventilation consists of a balance between air intake (at your eaves, soffits or fascias) and air exhaust (at or near your roof ridge). Try this ventilation calculator.
