Some clients have asked us, Why Use Static Vents in my roof? There are many ways to vent your roof and remove air out of your attic to help sustain the longevity of both your roof and your roof structure. Static vents come in a variety of shapes and sizes but they all are there to do the same thing – help create air circulation for both practical and economic reasons. These box vents are also called Flat Vents, Low Profile Vents, Louvers, and Turtle Vents. They have no moving parts and are installed over a hold cut in the roof which will allow heat and moisture to escape from the attic thereby saving energy and prolonging deterioration of your roof.
These static vents are made out of hard plastic or metal and come in a variety of colors. They are most effective when installed in an even line close to the roof ridge which will allow the maximum amount of heat and moisture to escape. Because they are less efficient then some of the other venting systems numerous box vents may be required. The cost of these vents run between $10 and $50 less installation. It is possible to over or under vent your home so getting a free quote from a reputable roofer is encouraged before attempting the job yourself.
Static roof vents encourage natural airflow and enhance the overall comfort of your home by providing escape for hot, stale, and moist air which can reach temperatures of 150 degrees in summer or hotter depending on where you live. During winter in Colorado you need to displace that hot air before it condenses and leads to wood rot and mold. Also, warm air trapped in the attic during winter may cause a rapid melting of snow which can then refreeze as ice dams. This ice can wreak havoc by pushing up shingles or splitting gutters and soffits.
How much roof ventilation you need should probably be left up to the professionals. A rule of thumb for proper ventilation is one square foot of vent for every 300 square feet of attic floor space. Having improper ventilation could possibly void any roof warranty you may have. Here are a few tips for maintaining adequate ventilation once your vents have been installed:
- You or a professional roofer should do an annual check on all your vents
- You need to clear vent screens of dirt, dust, pollen, leaves, bird nests and any other debris that will impede air flow
- Any ripped or torn screens or flashing should be repaired
- Check for rust or rotting around the flashing
- Be sure to clear insulation away from soffit vents by checking in your attic
