| Continued from ventilation page 2 Ridge Ventilation
Ridge ventilation is a highly effective method of ventilation for certain types of roofs. Ridge ventilation completely and continuously vents the attic. It is also highly effective in cutting energy costs and prolonging the life of the roof. First introduced in the 1970's, manufacturers have gone to great lengths to improve ridge ventilation components.
Early ridge vents were constructed of galvanized metal or aluminum, while effective they are prone to bending and denting during installation and severe weather. Another drawback to the metal ridge vent was appearance, as it detracted from the roof's aesthetics. The late 70's early 80's the "curb appeal" of ones home, and subsequently the home's roof, became a factor, this led to the evolution of the ridge vent.
The shingle over vent appealed to the concerns of aesthetics, as the component of the vent itself was masked with a ridge cap to match the roof shingles. The early shingle over vents were rolled out over a slot cut along the ridge, fastened to the roof with nails, then the ridge cap shingle installed over the vent. This type of system is still in use today. Note: metal ridge vent components are still in existance and very effective for metal, tile and slate roofs, with roofing material installed over the vent.
A ridge ventilation system with similar attributes is the Fold a vent unfolded along the ridge, with ridge cap installed over the top of the vent system.
A new highly functional, aesthetically pleasing ridge ventilation system is comprised of individual components, the vent and ridge cap is one unit, which are installed along a slot cut along the ridge of the roof individually to form a continuous ridge ventilation system. While this is not an option for ALL roof designs, it is a preferred method for roofs where installation is possible.
