As practical Clinton Township MI homeowners, we want to avoid unnecessary expenses all the time. Unfortunately, maintaining a home isn't meant to be frugal. However, making the right investment guarantees you won't incur extremely problematic expenses in the future. Residential attic ventilation is one way you can save from financially-demanding roof repairs.

However, if you've already installed an attic fan and porous soffits allowing air into your attic, you might not have to ventilate it any further. On the other hand, any sign of water damage or drenched roof decks is a sign you might need to make your ventilation better. Roof Tech has an excellent post that helps you know whether you need better residential attic ventilation.

Signs Your Roof Needs Better Residential Attic Ventilation

Your roof looks fine from the outside, but just like your plumbing and your body, that doesn’t mean it’s structurally sound. Maybe your energy bill spiked, maybe your roof weathered a bitter winter, or maybe you’ve neglected inspection for too long. In any case, you worry that your roof stands in danger.

Roof ventilation represents one of the most crucial methods of keeping a roof and home healthy. Unfortunately, ventilation problems can prove insidious, developing without a homeowner’s knowledge.

Luckily, inadequate ventilation often comes with distinct symptoms. If you suspect a ventilation issue, watch for these six signs.

1. Debris

Sometimes ventilation problems come not from a poor venting system, but from poor system maintenance. Think about the last time you cleared the space around your roof vents (or had a professional complete the task for you). If you can’t remember when it happened, you likely have a buildup of twigs, leaves, and dirt blocking your vents. You may even notice debris slipping into your attic space.

If you performed a recent cleaning, buildup can still occur after a severe storm. If you notice a change in your energy bill or temperature regulation after a storm with high winds, schedule a time to have a roofer clear your vents.

2. High Temperatures

Your ventilation system allows air to circulate through your attic. It may seem like this makes your heating and cooling system less efficient. However, this regulates the temperature in your home. If you suspect a ventilation issue, place a thermometer in your attic. If the temperatures climb in the summer, contact a roofer.

3. Insulation Issues (continued)

It's important to know if you have adequate attic ventilation. You won't need to spend so much to achieve proper insulation and attic ventilation to reduce moisture levels and ice dam developments. Some individuals and groups are promoting false information about attic ventilation. Home Advisor has compiled a list that talks about the common myths of residential attic ventilation -- such as having more ventilation at home is a good thing. More on this below.

Myths That Most People Believe About Residential Attic Ventilation

Few things are more misunderstood about the home than attic ventilation. In essence, all ventilation is about circulating air to keep it fresh and to reduce moisture levels. About 90 percent of homes in the US have unreasonably high levels of moisture.

Understanding whether your home could benefit from some form of attic ventilation might just be, if not a life-saver, a roof-saver. Here are some of the myths and the facts you need to know about attic ventilation.

1. More Attic Ventilation is Good

Just like properly sizing your furnace and air conditioning unit, you want precisely the right amount of attic ventilation for your home. Insufficient ventilation can lead to moisture problems during the winter and decreased energy efficiency during the summer but too much ventilation can be just as bad, if not worse.

Roof vents create an additional roof penetration, essentially another place of vulnerability where leaks can occur. Some vents are necessary, but you don’t want to needlessly increase the number of roof penetrations. More than leaks, these seams can cause blowouts during a hurricane or allow sparks from a wildfire to enter your home and set it ablaze. (Continued)

Residential attic ventilation is costly in its own way. However, if it cost you beyond $1,000 to create a steady airflow into your attic to reduce moisture and ice dams, then your project is definitely over-estimated.

Roofing Calculator has a great breakdown on residential attic ventilation costs. In fact, they include the costs of different kinds of vents including ridge and soffit variants.

2018 Costs To Install A Roof Vent

The average cost of installing roof vents is $300-650, depending on the vent type, and job complexity. By choosing the right vent you resolve one of the biggest problems that plagues most roofs – poor ventilation.

Over time, lack of proper air flow results in rotting of the wood deck, shorter shingle life, mold growth, ruined insulation, and high energy costs. Depending on your roof structure, there may be various types of roofing vents you can install.

We will review the costs and features of soffit, dormer, solar and ridge air vents, to help you decide which ones would benefit your roof.

It is best to have a professional come and inspect your house and roof, to determine the best venting system for your particular needs.

As the name suggests, this air vent is installed along the ridge of the roof. It features a finishing ridge cap that matches your shingles. Because it is a continuous vent, it can exhaust the hot air rising from the inside with a vacuum-like effect. This makes it most effective out of all passive vents at achieving good air circulation. Another advantage is that it is very dependable and not as susceptible to leaks, compared to a singular soffit or dormer unit. (read more)

It sounds like a huge and unnecessary burden to have proper attic ventilation for your home. However, it's an important procedure for any homeowner who intends to prolong the lifespan and performance of their roofs.

Good airflow in your attic prevents ice dams from forming on your roofs. This happens when cold weather creates ice formations on roofing materials while heated air increases the internal roof temperature. In turn, it creates massive snowmelt, which will drench and hugely damage your roof. Ice dam protection isn't the only protection you receive from proper attic ventilation. GAF has an excellent list of attic ventilation benefits you should know.

Why Should You Have Proper Attic Ventilation?

Properly installing a roof involves much more than putting on the shingles. Whether it’s in warm or cold climates, proper attic ventilation plays a key role in helping to make the roof system last longer and prevent many expensive issues from occurring inside and out of a building. Contractors should explain to homeowners why proper attic ventilation is so important with the benefits below. It serves two key functions:

In cold climates, ventilation helps maintain a “cold” roof system by mixing cool outside air with attic air to allow for less snow melting on the roof, therefore avoiding damaging ice damming. In warm climates, proper attic ventilation helps expel hot air, which can contributes to moisture problems. (Read More)

You might think "since attic ventilation is just simple to perform and no materials are needed, can I do it by myself?" If you have prior experience in roofing DIY, you can conduct attic ventilation efficiently. Attic ventilation works by letting external air into your soffit vent, which will flow in the attic airspace and regulate the attic temperature efficiently.

Construction Pro Tips have an excellent step-by-step guide to proper attic ventilation construction, which can greatly work to your advantage.

Constructing Your Very First Attic Ventilation System

It’s all about airflow

Roof ventilation is based on the simple fact that warm air rises. In summer, the sun heats air in the attic. In winter, heat from your home warms attic air. In either season, good venting occurs when cool air can enter the attic near the eaves and exit near the peak. Ideally, half of the vent area should be low and half high. The ultimate goal is that the temperature and humidity levels in the attic space match the conditions outdoors.

Paths to good venting

For intake air, soffit vents are best. Air can passively exit through ridge vents or hood vents. Turbine vents harness the wind to suck air out of the attic. Electric-powered vents are the ultimate air movers but aren’t necessary in most situations. Gable vents can help by allowing air in or out, but they don’t usually help the air flow evenly throughout the attic.

Bad ventilation, big problems

Moisture damage

At this point, you're definitely wondering how much will an attic ventilation project cost. Figures show that it isn't quite as expensive as a roof installation or replacement. You'll only need to purchase roof vents and equipment. Most of attic ventilation depends on the ventilation design efficiency.

Roof ventilation isn't just to help you prevent ice dam water damage. It works in preserving your roof during warmer temperatures too. If you want an accurate market-based price calculation, check out Home Advisor's post below.

Average Costs to Install Attic Ventilation

Installing a roof vent costs between $300-$650 on average, including labor and materials. Exact rates depend on the type, size, and number of units you choose to install. Ridge vents cost $2 to $3 per linear foot. Roof vents come in a variety of styles and range from $10 to $500 each.

Ridge models run the length of a roof's peak and allow warm, moist air to escape. Soffit vents run along the underside of eaves and enhance airflow by allowing it to enter from outside. Roof and gable versions provide a single point of exit and entry for air. The best system is a combination of ridge and soffit units. However, any airflow is better than none.

No matter what you've heard, roof ventilation is not just for warmer climates. It extends the life of your roof by reducing condensation that can cause structural damage. Since a new roof is one of the most expensive projects a homeowner can undertake, ventilation is a necessary and sound investment. Remember, your attic must be airtight for proper airflow, and there may be an additional cost to seal your roof. To achieve adequate airflow, consult a professional roofing contractor. In most cases, a homeowner does not possess the expertise to do this work him/herself.

Ridge Vent Cost Per Foot

Expect to pay $2 to $3 per foot for ridge venting, not including installation. They sell in 4-foot sections for $8 to $12 per section. The average home with a peaked roof will require 40 to 50 feet of material for a total cost of $80 to $150. You will also need connector plugs and straps at $5 to $6 each to adjoin pieces. Estimate $10 to $15 per 5-lb. bag of roofing nails and $20 to $30 per 200 to 300 specialty roofing screws with neoprene washers that create a seal. Homes with flat roofs or other designs without ridges will require another type of ventilation. (continued)

Not everyone’s aware of what attic ventilation is and what it does. For one, attic ventilation could be a bit technical-sounding. Also, it’s not like your usual exterior element (windows, gutters, siding, etc.). You don’t see it on a normal basis either. However, we strongly believe that it is still something that more homeowners should be concerned about. The role it plays contributes to the overall welfare of your property.

What is Attic Ventilation?

To understand the benefits of proper attic ventilation, we first need to discuss what it is all about. To explain it in simpler terms, let’s look at the root word of ventilation. “Ventilate" means that there’s moving or circulating air. Technically, the warm air is released while the cooler air enters a certain enclosed room or area. (This is also what happens to your attic.)

Proper attic ventilation is the provision of ample air to flow in and out. There’s a term called “air exchange” that takes place whenever there’s a need to release heat. It is then replaced with fresh air coming from the outside.

Proper attic ventilation is crucial in keeping your property's temperature balanced.

Attic ventilation is more than just your usual exhaust. It’s actually a continuous process of regulating the air movement to make sure that the temperature doesn’t rise too high or too drop too low. Clearly, there’s science behind it.

What are the Key Benefits of Proper Attic Ventilation?

Not all attic ventilation is the same. There is a difference between a well-ventilated attic as compared to something that isn’t designed correctly.

Prevents Moisture

Moisture is one thing that you should watch out for as a homeowner. This could lead to many different water damages that are not only bothersome visually but could also be costly to fix.

Faulty attic ventilation system may cause water retention. This issue may also lead to more serious water damages like stains and leaks.

To avoid water retention that may result in moisture, the air should continuously move in and out of the attic. Improper attic ventilation could potentially trap air that may cause moisture to proliferate. This is something that you don’t want to happen so that you wouldn’t have to deal with more serious issues later on.

Keeps the Attic Mold-Free

In relation to the first point, if there’s no moisture, there won’t be any breeding ground for plant growth. Note that molds, mildew, fungi, etc. are not only harmful to your property but to your health as well. There are cases reported that these plants caused severe allergies and asthma as they release toxins to the air you breathe at home.

Molds found in the attic area

Damp areas in your attic are the perfect breeding ground for molds and mildew. These are harmful both to your health and your property.

Energy Efficient

Did you know that attic insulation can help reduce your energy bills? Yes, you read it right! It becomes energy efficient when installed correctly for it has the capability to improve the temperature. As a result, it helps reduce the need for cooling appliances. For instance, during the summer months when it becomes too hot, proper attic ventilation could help replace the heat with cooler air. It efficiently improves the flow of air coming in and out of the attic so that you wouldn’t have to suffer from the summer heat. When there’s a right amount of air temperature, you wouldn’t be needing to turn on your air conditioning units more often which also means more savings for you and your family.

Prolongs the Life of Your Roof

If you think that the attic ventilation isn’t that important, you have to think again. Here’s why: A well-designed attic ventilation can help extend the life of your roof. It lessens the need for premature repairs and pushes the timeline when it comes to expensive replacements.

An excessive amount of heat trapped in your attic can damage other parts of the roof such as the underlayment. This part, found under the shingles, may absorb heat and eventually become brittle. Once they become brittle, they are no longer useful. On the other hand, if there’s a balanced temperature in your attic, you help protect its overall welfare. Note that too much heat in your attic area may damage areas surrounding it.

 Stops Ice Dam Formation

Ice dams are solid crystal-like icicles found mostly on the edges of the roof. Now, it there’s poor attic ventilation, too much heat escapes the attic area. If there’s not enough heat to melt the ice, it will continue to freeze and form into ice dams. While ice dams are pretty to look at they may lead to more serious problems like leaks, water stains, damaged roofing shingles, and many more.

If there’s enough attic ventilation, snow will melt and naturally exit through the drainage system.

Final Words

Attic ventilation plays an integral role in regulating the temperature. It maintains the right temperature by making sure there’s air flowing in and out.

On the flipside, poor ventilation may lead to premature damages as it enables moisture to penetrate the interior parts of your property. It also causes other issues like damage to underlayment and growth of molds.

Roofing is a huge investment. Protect it by make sure there’s proper attic ventilation. Of course, not everyone understands how it works. After all, there’s science behind it. You need ample training, skills, and experience in order to develop a functional and well-designed attic ventilation.
