The Only Guide You Need to Properly Ventilate Your Roof
A roof’s ventilation system helps keep a home warm, comfortable and dry. It also prevents mold and mildew buildup, keeps shingles from getting too hot and prematurely aging, and protects the eaves from water damage.
Unfortunately, many homeowners overlook this crucial part of their roof’s performance. If you want to increase your home’s efficiency, lower your energy bills and extend the life of your roof, it’s time to tackle your ventilation issues.
Roof Ventilation
The Only Guide You Need to Properly Ventilate Your Roof
If you want to make sure your home is as healthy and comfortable as possible, it’s important to properly ventilate your roof. Having the right amount of ventilation in your attic will keep your house cool in summer, prevent moisture buildup and help your shingles last longer.
There are a few different types of roof vents you can choose from to properly ventilate your roof. They include soffit vents, ridge vents and gable vents. Soffit vents are installed along the soffit of your eaves and can be made out of aluminum or PVC.
Ridge vents and gable vents are both intake and exhaust vents, but are typically placed on the ridgeline of your roof. These vents are designed to let hot air out of the roof while bringing in cooler air from the outside.
A balanced venting system will keep your home comfortable throughout the year and help you save money on energy costs. Most building codes require that you have at least one vent for every 150 square feet of insulated ceiling space.
Having enough ventilation is especially important in warm climates where your roof can get very hot and cook the shingles. A properly vented roof can reduce your energy bills by up to 50%!
Another benefit of proper ventilation is that it helps to prevent mold and mildew growth. This is because your home produces a lot of moisture from things like laundry, cooking and showering.
Without proper ventilation, these vapors will get trapped in the attic, and will condense on cooler surfaces. This can cause mold, mildew and dry rot to form.
These problems can be costly to repair. And they can even lead to your shingles failing and your home leaking.
The only way to ensure you have the right amount of roof ventilation is to talk to a certified roofing professional. They’ll be able to tell you the correct amount of roof ventilation for your home and will help you choose the best type of vent for your needs.
Attic Ventilation
The Only Guide You Need to Properly Ventilate Your Roof
In most homes, the eaves and soffit are designed to have passive air vents that naturally ventilate the home. However, insulation and other items may block the soffit vents from functioning properly. To prevent this from happening, a homeowner must be aware of the vents that already exist and ensure they’re not being covered up by insulation.
A homeowner can also test their attic ventilation by touching their ceiling on a warm day. If the ceiling feels hot, this means that the attic is storing hot air and needs more ventilation.
While it’s not a guarantee that your home will need additional attic ventilation, it can provide a quick and simple way to determine if you should invest in some new roof vents. It’s also a great way to gauge your roof’s overall ventilation and whether or not it needs any repairs.
Attic ventilation is crucial for preventing costly roof, structural, and remedial repairs. It helps prevent condensation that leads to mold, mildew, and rot problems, while increasing roof shingle life and preserving the structural integrity of the home.
To calculate the amount of airflow your roof needs, you must first determine the volume of your attic space. This is usually done by multiplying the square footage of your attic by 0.7, but it will vary depending on the slope of your roof and the number of hips, valleys, dormers, or gables.
For example, a sloped roof that has more than one dormer or valley will require more ventilation than a steep roof. This is because the slope of the roof creates a large volume of attic space and requires more ventilation to exhaust heat and moisture.
You should install intake and exhaust vents in equal proportion to the area of your attic. These should be located at the soffit and eaves levels and at or near the top of the attic.
There are several types of vents that can help you achieve proper attic ventilation. Some of these include gable vents, ridge vents, and baffles.
Intake Ventilation
The Only Guide You Need to Properly Ventilate Your Roof
There are multiple benefits to properly ventilating your roof, including energy savings and preventing costly repairs. A well-ventilated roof can prevent heat and moisture from accumulating in your home, protect the structural integrity of your home, decrease your heating and cooling costs and extend the life of your roof.
Ideally, your roof is designed to keep warm air in the attic and cool air in the living space. However, without proper ventilation, this heated air can mix with water vapor from your daily activities and can linger in the attic, causing mold, mildew and other problems throughout your home.
Intake ventilation helps to control this temperature difference by bringing in fresh air from the outside. It can also prevent ice dams from forming in the winter.
It is important to have a 50/50 balance of intake and exhaust vents in your attic. Intake vents should be installed in soffits or lower on your roof slope near the eaves and exhaust vents should be located higher on the roof slope, typically ridge vents or off-ridge vents.
Exhaust vents pull hot, moist air from the attic into the living area, while intake vents draw in cooler, fresh air from the outdoors. The balance between these two types of vents is essential to keeping your attic conditioned and your home comfortable, even in extreme weather conditions.
The only way to determine the best venting for your home is by having a professional roofer inspect it. They will be able to tell whether your home needs roof intake or exhaust ventilation and what the exact ventilation needs are.
This will ensure your roof is well-ventilated and insulated from both the sun and the rain. It will reduce your energy bills, prevent moisture and mold problems from developing in your home and protect the structural integrity of your home.

Exhaust Ventilation
The Only Guide You Need to Properly Ventilate Your Roof
Whether you want to save money, reduce energy consumption or improve the performance of your roof system, ventilation is the key. Without it, your roof is likely to experience a variety of issues including mold growth and deterioration, excess moisture, ice dams, damage to your attic, insects and other critters that find their way inside and excessive heating and cooling.
There are many factors that influence the right number of intake and exhaust vents for your home, including the size of your roof, a regional climate and the design of your ceilings. This is why it’s important to consult with a professional roofer before determining how many intake and exhaust vents are needed for your roof.
Intake vents allow cool air to enter the attic space. They can be gable vents, soffit vents or ridge vents (where the two roof pitches meet).
Exhaust vents are also essential to ensuring that hot air is able to escape from the attic. They can be ridge vents, soffit vents, or a power vent that requires a motor to operate the fan.
It is recommended that intake vents are located at a lower point on the roof than exhaust vents. Ideally, a roof with sloped or angled sides should have shingled intake vents, while a flat-roof home may need a gable or soffit vent near the roof eaves.
One of the biggest reasons for a lack of proper roof ventilation is that warm air that rises up into your attic can stay there too long, causing it to overheat and increase the temperature in your home. This can lead to a buildup of extra moisture, which can cause the shingles in your attic to crack and begin leaking.
Another common problem is that snow and ice will melt on your roof more quickly if it is too warm. This can create an ice dam that can then back up into the attic and even underneath the roofing materials.
There are many benefits to properly ventilating your roof, but the most notable is that it can save you money on your heating and cooling bills. If your attic has poor ventilation, the heat from the sun will overheat your attic, which can then lead to mold and rot, resulting in higher energy costs and decreased efficiency. We understand that laymen might find all this hard to understand so we recommend leaving things to Wichita falls roofers.
