Copper roof vents provide an attractive and durable means of increasing the attic air intake volume necessary to effectively remove heat and moisture from your attic space.
Generally, the most damage done to your home from heat and moisture occurs during the hot summer months, but moisture can be a problem in the winter, also. Attic air temperatures can potentially rise to twice the outdoor temperature in 90 degree weather, without adequate ventilation. This increases cooling costs, and shortens the life of roofing materials. The most effective method for dealing with summer moisture and heat problems, which will also be more than adequate for winter weather concerns, is a balanced system of air ventilation that properly addresses both fresh air intake and moist air exhaust.
Typically, a home will have a system of air intake vents that run along the perimeter of the structure. These can be observed along the "soffit", which is the horizontal area below the gutters. These may be in long, narrow strips, or in multiple locations that can vary in size and shape.
Hot and moist air is exhausted through the top of the roof. This is accomplished by one or more methods, depending upon the size and shape of the roof structure. This can include ridge vents, "box" vents, or specialized roof ventilation products such as are the focus of this article.
A roof that utilizes the "gable" configuration (rectangular planes) will typically have numerous and lengthy ridges, which run along the top of each plane. This configuration is suitable for the use of various types of ridge vent, and "box" vents. The other type of roof style, known as the "hip roof" configuration (triangular planes), is at a disadvantage when it comes to proper ventilation. This is because there is much less ridge area that can be vented using the first two methods mentioned above.
Some older homes are not equipped with soffit vents, or may be designed in such a way that is either difficult or impossible to retrofit them. It is necessary to increase the air ventilation on the roof to compensate for this. Additional ventilation added at the top of the roof would normally allow more hot air to be exhausted, but missing or inadequate soffit ventilation hinders air movement. Simply put, hot air rises. Without sufficient soffit air intake (low point), and suitable roof exhaust vents (high point), the overall process of ventilation is impeded. In this case (or just to enhance your home's overall appearance), there is another option, and that is to add a third method of roof ventilation.
Copper roof vents can be installed in a variety of locations on your roof, in order to provide additional air flow. The goal is to position them significantly lower on the roof than the other roof vents. Normally, "box" vents are installed on the back of a house, due to their utilitarian appearance. Copper attic vents not only provide additional intake airflow, but are also an aesthetically pleasing architectural element. They are most often placed on the front of a home, and perhaps on the sides, rather than at the rear.
Most of the copper roof vents shown here are 18W x 36H. Some are "arched" top, and some are "half-round" top. That element is simply a matter of personal taste. The top length will vary based on the pitch of the roof. A copper roof vent for a low-pitched roof requires a greater overall length than would be necessary in the case of a steep roof. We can customize these to your preferred size, and to the pitch of your roof. Copper roof vents for both low-pitched and steep-pitched roofs are shown in the following photos. Also shown in these photos are our Gem-style copper finials and our flat-seam copper barrel dormer roofs (available in "standing seam", also).
