Silver Spring Roofing: Article About The Importance Of Correct Roof Insulation
What is ventilation, and why is it so important for Silver Spring roofing? In wintertime, houses are sealed shut to trap heat inside. While people are inside conducting their normal activities, they create moisture in the process. Cooking, bathing and even talking can all contribute to a buildup of moisture, which rises up to the attic and condenses into water droplets.
The warm, dark environment of an attic facilitates the growth of mold. Mold is a fungus that grows as single cells or as organized multicellular filaments called hyphae. Mold spores are ubiquitous; there is no getting away from them at home or in the workplace. There are 50,000 different types of mold, some of which cause lung disease in humans and some that can rot the materials that make up the structure of a home. Mold is one reason why ventilation is so important.
There are also implications for energy bills. In metropolitan New York, for example, when the temperature gets up to 90 degrees Fahrenheit, the roof surface can climb to 107 degrees. The temperature in the attic may reach between 140 and 165 degrees. The whole house heats up, causing huge demands on the air conditioning.
As a general rule of thumb, for every 300 square feet of attic, there should be a 1-foot square hole in the roof to let air escape.

The best arrangement is for half of the ventilation to be at the top of the roof, and the other half at the bottom. Without a hole at the bottom for fresh, cool air to enter, there is no way for the hot air to escape. With correct ventilation, the temperatures of the air and the roof surface remain the same, but the attic cools by 20 or 30 degrees.
While having the requisite amount of holes in the roof is sufficient to ventilate a home, there are a plethora of devices available to improve their efficiency such as ridge, box and soffit vents as well as ridge runners and attic fans. Some attic fans are even solar powered and thermostatically controlled. Note, however, that attic fans should not be used with ridge vents because they are just sucking in the same hot air.
When a property owner invests a considerable sum of money in roofing materials that are warrantied for up to 25 years, it makes sense to ventilate the roof correctly to make sure it does not fail years earlier.
