Roof Ventilation

If your roof ventilation looks like this, call us! Roof ventilation components are often damaged during severe weather, which may prevent them from functioning properly. Proper ventilation extends the life of a roof and reduces problems because it minimizes the temperature differential between the attic and the air outside. Proper ventilation will remove moisture and heat from the attic. Trapped heat and moisture can raise energy costs, cause ice dams, and damage roof system components, where attic temperatures can reach extremely high temperatures. Condensation that forms inside attics can be caused by the use of washing machines, dish washers, bath tubs, showers, and tumble driers unless these items are properly ventilated through the roof. In some cases the condensation can be bad enough to be mistaken for a roof leak.

Improperly Ventilated Attic Space

Improperly ventilated attic space can lead to several issues, starting with warping of the wood decking due to excess trapped moisture. The plywood decking needs be able to “breathe” by being exposed to circulating air. Dry rot can also occur, and the adhesives in the plywood can break down, making the wood foundation of your roof weak.

Water vapor will condense on anything metal inside the attic, eventually causing the metal to rust. Insulation can trap moisture which will reduce the R-value of the insulation and facilitate the growth of mildew, molds, spores, and fungi. The roof system itself will deteriorate prematurely, and AC units will need to be serviced or replaced prematurely because of excessive use.

Attic Vents

There are many types of attic vents available today. There are static vents, power vents, ridge vents, turbine vents, soffit / cornice vents, gable vents, starter vents, and cupola vents. These all come in a wide variety of sizes, styles and shapes. Some will ventilate better than others depending on the roof configuration, attic size, climate, etc. To properly ventilate an attic, two types of vents are needed. Intake vents, which are located at the downslope edge of the roof and allow fresh air into the attic; and exhaust vents, which are located near or on the ridge of the roof and allow air to leave the attic. The use of an exhaust vent in conjunction with an intake vent uses wind pressure and thermal effect to ventilate the attic space. The general rule for proper ventilation is 1 square foot of net free area per 300 square feet of attic space, assuming ventilation is evenly distributed between the soffits and the top section of the roof.
