Homes that lack roof ridge vents have a tendency to suffer from issues that stem from a lack of ventilation in the home and attic. The root of the whole issue is that without proper ventilation in your roof, there is no escape route for outdoor air moving into the attic. You see, the main dilemma with conventional roofing is that the outdoor air flows into the attic, and then it has no way of escaping.
That’s one problem that roof ridge vent was invented to remedy… Roof ridge-vent lets the outdoor air that enters into the attic to escape back out through the top of the roof. This creates even air exchange, preventing premature aging and cracking that is commonly caused by the constant overheating that causes the roofing membrane to wear out early, and damages the inside of your attic.
Moisture gets released by common activities performed in the home, like running a washing machine, running a dishwasher or taking a shower. Moisture is one of the biggest causes of damage to walls, rafters, insulation, and shingles, in homes.
Here's The Problem: Why You're Attic Needs Proper Ventilation
With inadequate ventilation in your attic, the sun’s rays during the summertime can create a huge accumulation of heat in your attic. The temperature in your attic can reach up to 140°F on a 90°F day. An overheated attic, when put together with moisture, can create problems, like damages to your roof decking and shingles.
The excess moisture and heat work together to make your roofing system and decking warped, causing the material to deteriorate prematurely. The heat that is absorbed in your attic can then seep into your living areas causing problems with your refrigerators and other appliances, and your air conditioning systems and fans.
What happens is that the heat causes your cooling systems and appliances to work harder, increasing energy bills and decreasing their life span.
A lack of proper attic ventilation can potentiate problems during the winter as well… What happens in the winter, is warm, moist air from the lower parts of the home rise naturally up through the ceiling into the attic. The warm air seeps quickly through the holes in your ceiling where electrical and plumbing fixtures have been installed.
Then, when the cold air in the attic meets the warm, moist air, it causes the air to condense on cold surfaces of rafters, nails and other metal, causing rust and corrosion, which, as you already might know, eats away at the metal, causing problems with maintenance and eventually irreparable damages to the metal.
According to his article entitled Mold, Moisture, and Your Home on the InterNACHI® website, leaks in your roofing membrane or insufficient ventilation are two major causes of mold and mildew in homes. Mold and mildew, as you might already know can lead to a number if issues, even health issues if not addressed in time.
