Quick Recap about How Long Can I Expect My Roof System to Last

The ventilation system is, without a doubt, the most crucial component of a roof. The ventilation system on your roof determines how long it lasts. A roof that is well-maintained and has a good ventilation system will survive roughly 25% longer than one that does not. official site
The ventilation system on your roof is critical. Hot air can escape through a well-functioning ventilation system. If this does not occur, the heat in the attic will continue to rise. As a result, the shingles bake from the bottom up. This type of damage will shorten the lifespan of your roof by several years. This heat can also bake your roof’s sheathing, leaving it brittle. Brittle sheathing raises the risk of anything heavy bursting through your roof, such as a build-up of snow. Multiple layers of a roofing system will be weakened if the adhesive used to hold it together breaks down.
Your ventilation system will be determined by the form and substance of your roof. A balanced ventilation system, on average, necessitates a square foot of venting for every 250 to 300 cubic foot of air in the attic. Using this, determine the number of vents that should be installed in your roof. Vents come in a variety of shapes and sizes. Static open units and turbine-style vents are available, as well as thermostatically controlled and electronic vents. The size of the roof and the air space below determine which of these vents should be installed.

A proper ventilation system aims to achieve a balance between the air coming in and the air leaving. Without sufficient ventilation, temperatures in attics can rise as high as 150 degrees Fahrenheit. Personal items can easily be ruined if they are stored in an attic that is this hot. Condensation from washing machines, dryers, and showers can also cause issues. It’s possible that they’re venting directly into your attic. Bacteria and viruses thrive in this environment. These viruses can enter your home through a shift in air pressure caused by someone opening an attic door.
