Roof Vents: Why They Are Important

Roof Vents: Why They Are Important

Roof ventilation permits air to circulate through the attic. Every home needs roof vents, but few homeowners understand their roofing ventilation systems. Roof vents have numerous benefits. They prolong the roof’s service life, manage internal temperatures and save energy. A well-ventilated attic also protects against decay.

Read on to learn more about the importance of roof ventilation and how it protects your home.

  1. Prevents Condensation, Mold and Rot

Laundry, showering, bathing, cooking and other activities create warm, humid air in your home. Moisture rises to your ceilings and, without a vapor barrier, ends up in your attic. The warm air that reaches a cool surface, like the underside of your roof, condenses. The condensation from this “trapping” of air can create an unhealthy environment conducive to mold and mildew growth.

  1. Increases Energy Efficiency

Proper roof ventilation allows heat to escape, lowering cooling expenses. As the outside temperature rises, so does the temperature inside. Insufficient ventilation traps heat in the attic, forcing your air conditioner to work harder. Proper ventilation can reduce your home’s cooling and heating bills.

  1. Increases Roof’s Lifespan

Inadequate roof and attic ventilation can drastically shorten roof lifespan according to a trusted roofing contractor. Non-ventilated roofs can generate excessively hot attics, causing damage to wood framing, rafters, underlayment and more. Proper roof ventilation allows that trapped air to escape and increases the life of your roofing system.

  1. Reduces Indoor Temperature Extremes

Uneven or non-ventilated roofs might cause significant temperature changes. Proper ventilation prevents indoor temperature extremes. It lets hot air out and cools the air in. A super-heated attic can increase your heating and cooling expenditures. Overall, good ventilation will make your home more comfortable all year.

  1. Prevents Ice Damming

If you reside in a snowy climate, good attic ventilation reduces the chance of damaging ice dams. Warm air reaching the roof deck melts snow on your roof, causing ice dams. This melted snow can run off your roof and produce ice dams on your home’s overhangs.
