How does a Ventilating Cupola provide Attic Ventilation?

Copyright (c) 2009 Elda Titus

“More gold has been mined from the thoughts of men than has been taken from the earth.” By Napoleon Hill

The American Institute of Architects estimates 90 % of U.S. high levels of moisture in the homes.

Adding a cupola provides passive ventilation to the roof allowing trapped heat to escape with a natural flow in an upward direction through the sides of the cupola.

A roof saver, attic ventilation is all about circulating air to reduce moisture and bring in fresh air.

According to studies conducted by the U.S. Dept. of Energy and the American Society of heating and cooling engineers the benefits of roof ventilation is supported.

Insufficient ventilation can lead to moisture problems during the winter and decreased energy efficiency in the summer.

In an unventilated attic the roof sheathing may reach a temperature of 160 degrees Fahrenheit when the outside temperature is in the 90′s.

The attic heats from direct sunlight on the roof that radiates heat. This is then transmitted through the roofing material to the attic floor or the top surface of the ceilings insulation, causing the attic air to become heated.

The attic floor then acts as a “hot plate,” radiating warm air in the rooms below, causing an increase in your air conditioning requirements.

A ridge vent, such as a functional cupola, helps provide air circulation in the attic and allows for excessive attic air to escape through its sides on the top of the roof.

Suffit vents found along the bottom perimeter of the attic space, work well when used in conjunction with ridge vents to promote the circulation of attic air.

In colder climates, preventing moisture damage is a much greater benefit then in warmer climates.

Attic ventilation is required in colder climates to evacuate the warm, moist air that builds from the living space below. This air can condense causing the roof sheathing to rot.

Circulating air from ventilation helps prevent ice, dams, which form when warm air in the attic melts the snow and creates a run off that refreezes on the colder eave.

Suffit vents allow air to enter the attic at the lowest point of the roof. They are more effective when used in conjunction with a continuous ridge vent, such as a cupola.

Adding a cupola to the roof allows a way for trapped heat to escape, by providing a natural flow in an upward direction through the sides of a cupola. This passive ventilation lets the warm air escape while bringing in cool air.

Cupolas were originally designed for functionality, as a ventilating system. Today there has been a rebirth of interest in cupola for decorative architectural accent as well as the functional aspect of ventilation, and are placed on the roof tops of houses, garages, businesses.

Cupolas not only improves the attic ventilation they provide an eye-catching exterior focal point which adds warmth, tradition and a little country charm that will add value to your property for years to come.

Every Homeowner Should Know About Bathroom and Attic Ventilation

Attic ventilation is a critical component to maintaining even temperatures in your attic all year long. In the summer it saves on the life of your shingles by keeping the boards cooler and decreases your cooling costs in the winter weather by diminishing the temperature difference which in turn prevents moisture build up in the form of condensation. Did you know that having a proper amount of attic ventilation is even required to enforce the warranty of most shingle manufacturers?? When it comes to mold the most import ventilation concerns occur in the winter. In the winter during the coldest months as we run our furnaces, hot air escapes into the cold unheated attic space. When the escaping hot air emerges into the cold attic it rises as heat always does. It seeks out the highest portions of the attic where it then coalesces against the cold boards of the roof. This hot- air-mass-meets-cold-surface phenomena results in a condition known as dew point, which creates moisture in the form of water droplets and ice crystals. The nails themselves also will contribute to this moisture problem as iron is a good conductor of temperature and will readily convey the biting chill of cold winter air directly inside the attic. The evidence of this can be seen in the form of drips and of drip spots underneath the nails themselves.

Bathroom fans vented directly into the attic or Soffet areas rather than straight through the roof are also to blame for exacerbated moisture problems which lead to mold, wood- rot and health problems. The more adults showering in the house and the longer the showers the more moisture will enter an attic. In fact in some families the bathroom fans alone are the sole culprit responsible for major mold infestations!

If you want to eliminate attic mold permanently you need to get equal amounts of intake air and exhaust or out-take air into your attic.

Building scientists have proven that using a balanced ventilation system that utilizes equal amounts incoming and out going air. Incoming air comes in from under the eves through vents cut in the underside of the roof overhangs which are called soffets. Proper Soffet ventilation is essential to large amounts of incoming air needed for intake. Many attics were originally vented properly but have become packed with insulation along the way by an over-zealous insulation contractor or homeowner, in an attempt to actually stop air from coming in, sadly a common mistake. This mistake was very common in the 80′s and 90′s.

There are two basic types of Soffet vents: either a contiguous vent or a individual vents which come in round and square varieties. I generally prefer to use 6 inch by 12 inch square vents because of the ease of installation and the low material cost. They work surprisingly well and offer a lot of surface area. They can be purchased easily in brown white and silver to match virtually any siding.

Attic Insulation in Atlanta – a Hot Topic

For nine months out of the year, it’s difficult to even broach the subject of one’s attic in Atlanta. It can become as “hot as Georgia asphalt” and so for the most part, we all leave that lonesome area of the house alone most of the time. The subject is more palatable as the winter rolls around because it offers a nice level of warmth to counteract the cold outside. But cold or hot, when was the last time you ventured up there? We can’t forget that part of the house as a valuable area of temperature control year-round for the floors beneath.

And that’s what I want to focus on. The truth of the matter is that many homes in the metro Atlanta have poor insulation, which is really a shame. It’s a shame because in exchange for a relatively small amount of time and effort, the rewards are great in a short period of time. Put more succinctly, by insulating properly you’re saving in heating and air conditioning costs immediately.

My experience as an Atlanta area roofing contractor is that if your attic even has insulation, it is only in the ceiling and it’s probably fiberglass or cellulose that was blown in. If you look closely at it you will see that it has settled and lost a large portion of its insulating value. The cure here is to spend some time in moving some of the insulation around on your own or hiring someone to do it. (If you choose to do this on your own, we highly recommend that you wear the proper clothing to protect you from the insulation–latex gloves, eye protectors, jeans and long-sleeve shirts.)

If the insulation hasn’t spread and has deteriorated over the years, you may need new insulation. There are a couple of ways to determine whether you need new insulation. One is to climb up there and do a visual inspection. Another is to take note on whether you’re AC/heating units are having to work harder in the summer/winter times of the year. If you’ve notice these bills go up, then the insulation may be the big culprit.

I recommend that you do a check once every year…along with checking the vents and any roofing issues you may have. This will keep things in check. And instead of just “maintaining” the insulation you now have, why not look for further ways to save…such as insulation in other areas of the attic…along the walls, etc.? You may be able to save more than you’ve ever experienced.

And don’t forget about the advancing technology of the insulation materials either. There’s a new product out now called polyurethane foam roof insulation and it has twice the insulating or “R” value of the conventional insulation you have in the attic. It’s applied on the surface of the roof under the roofing material. The benefit of this arrangement is that you don’t see it (doesn’t detract from the roof’s aesthetics) and it adds yet another level of insulation and savings. Other benefits- it lasts for the entire life of the home and helps to seal against roof leaks that are inevitable with the roof’s age. I highly recommend this option for homeowners who are considering a new roof.

The bottom line is this…take stock in what’s going on up in your attic. It can be an expensive area when unchecked. Conversely, it’s an area where you can potentially save money where you never expected or anticipated saving.

Why You Should Have A Solar Attic Fan Installed

For those of you who are lucky to have an attic it’s generally advised that you buy an attic fan. There are different types available however buying one which is solar power offers a number of advantages. Not only is it great for those who want to reduce their impact on the environment but it also means you don’t have the hassle of installing loads of cables. Having an electrical engineer in your home can be very expensive so buying solar power can save you a lot of money on installation and running costs.

One of the problems faced with attics is moisture and your solar attic fan can be set up to work automatically as it’s able to store power gained from the sun. Because it’s solar powered you don’t have to do much to install it and they are very simple units so the chance of them breaking down is minimised.

You don’t have to live in the middle of a desert to experience hot temperatures. Most places in the world will suffer at least a few days or weeks or raging heat. Most people living in hot climates will already have some air con units installed in their homes but for the rest of us who live in a temperate climate, this is not something we normally have the luxury of. Even if you do have air con units or cold air fans, the cost of powering these can be astronomical. Energy costs are becoming more and more expensive and less affordable so it’s important that we look for alternatives such as solar power.

If you have ever had to go into your attic whilst there is a heat wave you will feel like you’ve just walked into an oven. It’s so hot you may even feel as if you’re going to pass out. Luckily an attic fan will transfer the hot air in your attic outside bringing the temperature of your attic back down to a much more tolerable temperature.

Attic fans along with gable ventilators work on the same principal of having a solar panel positioned on the roof. The panels takes the energy from the sun’s rays and this energy is then stored into battery so that the ventilation can work even at night or when it’s very cloudy. Although installation is quite easy if you are used to DIY, having the solar panel placed on the roof is the part which you may find a bit more difficult. For those of you who are used to carrying out DIY tasks in the house you should find this easy, otherwise you can just get a tradesperson in to do the job for you.
