Constructing a roof is more than just throwing up shingles onto a roof deck and nailing them down. Builders have to plan ahead to make sure the Summerville roofing is sturdy, water-tight and energy efficient. Two of the most important factors for a well-built roof are insulation and ventilation.
Insulation is important to keep the heated or cooled air inside the climate controlled living spaces. Anytime air escapes, it wastes energy and money. Insulating the attic floor is important. It is also important that the roof have some form of insulation.
Roofs need ventilation in all climates: hot, warm and cold. In a cold climate, ventilation helps keep the roof cool to prevent melted ice and snow from damaging the roof. Hot climate roofs need ventilation to keep the sun-warmed air from continuing to heat up in the small attic space, forming moisture in the insulation and on the roof deck. Insufficient ventilation can also cause other problems in all climates including warping of the house frame, mold, mildew and water damage.
Your ventilation system needs to keep air moving through your attic or vent space. A huge difference in temperature between the roof surface and outside air can cause condensation. Keeping the outside air flowing through helps balance out the temperature difference.
There are many different types of ventilation. Some of them include attic fans, soffit vents, powered roof vents, static vents and ridge vents.
