Cobra ® Snow Country ™
Recently there have been many questions asked about proper roof ventilation; specifically ridge ventilation. The role of roof ventilation and conflicting opinions as to which application best serves your roof is often debated among local roofing contractors.
Today we will visit the anatomy of Cobra Snow Country ridge ventilation and exactly how it enhances the life of the structure of your roof, as well as the shingles.
There are many features of Cobra Snow Country that make it one of the best roofing ventilation options. It is visibly appealing because it is integrated into the ridge of your roof and does not stick out like conventional “hat” or “mushroom” style vents, it can be installed on roof pitches from 3:12 to 16:12, and it provides 18 sq. inches per linear foot of net free ventilating area, just to name a few. However, one question that arises over and over is whether it will leak through the venting perforation? The answer is no.
As shown in the illustration, the perforation of Cobra Snow Country is protected by a vertical lip or edge which eliminates the possibility of water infiltration. Moreover, this lip or edge aids in the ventilation of your roof when air passes over it; drawing air and heat out of your attic. Unlike other conventional vents, Snow Country is designed to use the increased air velocity created by the slope or pitch of your roof as wind travels upward, and converting that force into useful ventilation, even on days when wind velocity is minimal.
Despite varying opinions, Cobra Snow Country is a reliable and efficient roof ventilation application that any homeowner should consider when having your roof replaced or repaired.
There are many services that roofing contractors can provide to maintain your roof and protect your home throughout the harshest summer and winter seasons. Attic ventilation services is one of the most important jobs that a roof repair contractor can offer.
During the summer months in the Midwest, an improperly ventilated attic can cause heat to build to temperatures in excess of 160°F! This excessive heat creates downward pressures which penetrate the ceiling insulation and migrate into your living area below. Moreover, You also cannot have a valid manufacturer’s warranty on your shingles without proper ventilation. As such, not only will improper ventilation reduce the lifespan of your roof, it will also void your manufacturer’s warranty, and rest assured that shingle manufacturer’s will send an inspector to determine this should your roof need replacement under a warranty claim.
A correct attic ventilation system provides for a steady flow of outside air from the lowest part of the attic through the upper most part of the attic. As shown in the illustration, proper attic ventilation allows the attic insulation to perform at peak efficiency and help maintain constant temperatures in your home.
There are many roof ventilation styles available on the market. Choosing the right style for your home is critical to providing optimum air flow and function.
