BuyManufacturers.com and HomeOver.com are two businesses that sell ridge vents. As of 2015, these companies offer black vinyl ridge vents for approximately $165. Ridge vents travel the whole length of the peak of a roof, cooling the whole roof deck.
Because ridge vents fit right over the peak of a roof, they often escape notice. They are also fairly easy to install, requiring only a hammer, circular saw and drill or driver from the tool box. In addition to the ridge vent kit, which comes with end plugs, the project requires 2-inch roofing nails and the shingles to go beneath the vent in order to complete the project.
