Roof ventilation is one of the most important aspects of most home roofing systems. Without adequate ventilation, the moisture that accumulates in the attic can damage that roofing system. Although many may consider the effects that external moisture has on their roof, few tend to think about the internal moisture. Rain, ice, and sleet are commonly taken into account when choosing a roofing system but not aways the ventilation system to ensure that the internal moisture has an adequate way to evaporate and evacuate before causing damage to the roof, shingles, rafters, or sheathing --- the roofing system.
Roof vents work by allowing air to circulate through the vents, which in turn, draws out the moisture in the attic. This circulation of air is vitally important to the maintenance and well being of the roofing system. The roof vent is installed along or near the top ridge of the roof. A roofing contractor can let you know which type and how many vents you'll need for you particular type of roof. Some roofs are extremely wide and may need additional ventilation to ensure good circulation.
Some of the major benefits of roof ventilation system is that it works throughout the entire year and isn't affected by which direction the wind happens to be blowing. It's generally best to hire a professional roofing contractor to give you a written cost estimate and has the equipment and experience for this type of project. If you have cathedral or vaulted ceilings, for example, the roofing contractor may need to install a ventilation system for the attic joists as well.
