The secret behind a long-lasting roof lies in—ventilation. All types of roofing systems require ventilation.

Proper ventilation protects the roof from damage caused by the sun’s rays. Direct sunlight can adversely affect roofing materials and structure via heat transfer. As a result, they shorten the lifespan of a roof.

Roofing ventilation basics

Roofing ventilation begins with the attic. To put it simply, roof ventilation systems regulate the flow of air into your attic. In general, these are the most commonly used roof ventilation systems:

Intake vent

Intake vents allow cool air into the attic. Found in the soffits or eaves of a roof, these vents are often used together in combination with exhaust vents.

Exhaust vent

Exhaust vents allow hot air to escape from the attic to the outside. These are located along the roof’s peak. Exhaust vents come in different forms, such as power vents, static vents and turbine vents.

Why roof ventilation matters

There are many benefits of a well functioning roof ventilation system:

  • Roof life: Depending on the climate of your state, the need for  ventilation becomes even more important. However, a robust ventilation system will always help extend the lifespan of your roof. In extremely cold temperatures, ventilation prevents the formation of ice dams. These ice dams are detrimental to the roof. It can freeze shingles. Alternatively, roof ventilation is fundamental in the summer. Direct heat can deteriorate roofing materials by causing the plywood to be hot and dry the asphalt roof from underneath.


  • Moisture: Ventilation prevents the formation of moisture in the attic. It has an adverse impact on anything metal, such as nails. Consequently, you can expect your roof to suffer over time. Not to mention, moisture can also result in mold, which can weaken the roof. If you live in tropical climates, ventilation is a must.


  • Saves energy: By releasing heat outside, ventilation systems help keep the high temperature in attics under control. Consequently, you can rely less on air-conditioners. Of course, this leads to energy efficiency and money savings.
