Proper Roof Ventilation

One of the most important aspects of your home to consider is proper roof ventilation. Unfortunately, most people don’t think about proper roof ventilation until they find that they have a leak or other problem with their roof. But, for those willing to invest some time and money into ensuring proper roof ventilation in their home’s roof, they will reap the reward of a longer lasting roof, as well as a much lower incidence of roof-related problems.

What Is Proper Roof Ventilation?

Proper roof ventilation consists of the appropriate amount of ventilation to ensure that hot air and moisture can adequately escape from the roof, rather than becoming trapped. When it comes to proper roof ventilation, however, there is not just one type of ventilation system that can be used. Different roofs have different ventilating needs. There are also different types of ventilation systems to meet those needs, such as ventilation fans or attic fans, ventilation boxes, ventilation strips, and soffit ventilating systems. Some are simply static openings that allow air to naturally flow through the vents. Others are oscillating fans that work to suck external air in and push internal air out. These can be operated in conjunction with a thermostat or can be set to go on at certain intervals.

The primary purpose for proper roof ventilation is to ensure that there is an adequate system of air flow between the interior and exterior of the roof. By regulating air flow, the hot air that builds up under roofing shingles can be transferred outside, while cooler outside air is drawn into the house under the roofing shingles to maintain appropriate temperatures. This also helps even when the weather cools, since moisture can build up in locations that do not have adequate air flow, leading to its own set of problems.

Why Is Proper Roof Ventilation So Important?

A home’s roof is exposed to constant heating by the sun’s rays, as well as a great deal of moisture from rain, snow and humidity. Add to that the fact that heat rises, and what you find is that there is a great deal of heat that sits under the roof. If this heat gets trapped because there is no proper roof ventilation, the result can cause damage to the roofing materials, a build-up of mold and mildew, and unsafe air temperatures in the attic. Proper roof ventilation is necessary to preserve the roofing materials, to maintain energy efficiency in the home, to improve air quality and to even prevent possible home fires due to extreme temperature conditions.
