Proper roof or attic ventilation is vital to your home. Many homeowners know this, but some don’t fully understand why, no worries, we are here to help with that.
For roofing material manufacturers to honor their warranties, proper ventilation is required. Ventilation is also a requirement for building codes. A specified number of vents is necessary per square footage to ensure the correct amount of air gets in and out of the attic. It is a good idea to confirm that you have the required amount of vents for your home before you replace your roof.
Roofs that have been properly ventilated last longer. In cold conditions, proper roof ventilation is important in preventing undesirable events such as ice dams. Ice dams occur when ice melts and refreezes at your roof’s edge, causing freezing of underneath shingles. The ventilation assists to free up any heat that may otherwise build up beneath the roof resulting in the premature thawing of snow. In hot conditions, a properly ventilated roof allows hot air to escape resulting in a cooler roof and attic. This prevents temperatures in your roof and attic from soaring to unbearable degrees, a condition that can damage your shingles both inside and out.
As explained above, proper ventilation enables high-temperature air building up in your attic to be released. This in turns cools your home’s interior and reduces the workload of your air conditioning unit. If the air conditioner is working less, it means lower power bills for you.
Proper roof ventilation will protect your roof by releasing any moisture that would have otherwise have collected on the roof deck. Moisture that is not expelled from underneath your roof deck will result in all manner of problems. Metal materials will in time be affected by moisture accumulation- rusted nails may weaken or break. Additionally, moisture buildup causes mold and fungi to grow and the roof deck itself may suffer from dry rot.
The right ventilation system also allows free circulation of oxygen and prevents the buildup of carbon monoxide, which is harmful.
So there you have it, now you know the benefits of having a well-ventilated roof and the drawbacks of roofs with poor ventilation. A properly done ventilation job will result in a comfortable and safe home environment for you and your family.
