Why Do Gazebos Have Holes? How Many Holes Required in A Gazebo?

    Gazebos are a great investment if you are looking for a versatile backyard statement piece. Gazebos can be large enough to fit a crowd of people, or cozy enough for you and a friend or two.

    Because of their wide variety of uses, they are a no-brainer must-have for anyone who is looking to relax in the outdoors without being exposed to rain, sun, or wind.

    Gazebos are a great choice for those who are looking to relax in the comfort of their own backyard without having to go indoors to seek shelter when the weather starts to turn a bit sour.

    When purchasing a gazebo, there are lots of important things to consider, like the style, size, weight, materials used, and price. Gazebos come in all sorts of options, with hard and soft, pop-up, and durability often used as selling points.

    However, one of the most important questions you have to ask yourself when purchasing a gazebo is how you intend to use it. All of the above considerations are moot if you do not first determine how you intend to use the structure.

    When looking at purchasing a gazebo, you have to determine what you’re looking to protect against – with rain, sun, and wind is the most important options to consider.

    Most gazebos offer varying degrees of protection against all three, which means having to make design compromises that, at first glance, may seem a bit backward.

    Not to worry though – nothing is wrong with your gazebo, these holes provide a purpose. Gazebos are designed to keep you protected against the elements when relaxing underneath it, so these holes will not affect your ability to enjoy yourself. The holes ensure the structure lasts for years of enjoyment.

    If your gazebo has built-in holes in the roof, don’t attempt to cover or plug them – they aren’t a defect, they are more useful than you think.

    Thankfully, these holes have individual purposes and are built into the design of the structure, so they take rain, sun, and wind protection into account.

    Why Do Gazebos Have Holes?

    The holes in gazebos help with the below-listed functions primarily

    1. Wind pressure relief
    2. Ventilation
    3. Drainage for pooling water

    1. Wind Pressure Relief

    Holes in Gazebos manage wind Pressure Relief

    If you are looking to set the gazebo up in an area with lots of high winds, look for durable, steel units with a wind resistance rating, and ventilation holes on the roof of the gazebo to allow for wind to travel through without compromising the integrity of the structure.

    These units often offer rooftop ventilation to assist with wind pressure and resistance. Always remember to securely bolt down all four legs of the gazebo to the ground – strong winds love to blow gazebos away.

    2. Ventilation

    Ventilation through holes in gazebos

    Both hard and soft gazebos offer ventilation options. which helps to circulate the air inside the tent when there are walls affixed to the sides of the gazebo.

    These ventilation holes are situated on the top peak of the gazebo. They are oriented vertically, instead of following the angle of the roof of the gazebo, with a two-tier awning covering the holes to avoid rainwater from entering inside.

    3. Drainage for Pooling Water

    Gazebo holes facilitate Drainage for Pooling Water

    Having holes in a gazebo helps to keep rainwater from pooling on the top of your gazebo, instead redirecting the water to drain off in an area around the perimeter of the structure.

    Some gazebo roofs are designed with some artistic flair in mind, which may allow for hidden pockets of rain to collect.

    Having these holes, otherwise known as leak holes, will help prevent this by allowing water to escape. These holes are usually placed in an area where people won’t be actively underneath, so no need to worry if you are sitting in the wrong spot in a storm.

    What Happens If Gazebos Don’t Have Holes?

    A gazebo without holes can lead to your gazebo breaking down faster when exposed to rain, sun and wind.

    1. Could Sag and Get Damaged

    If your gazebo does not have holes, the entire structure can sag. Rainwater can collect and put weight on areas of the tent that do not have the capacity to withstand it. This can cause the entire structure to be compromised.

    2. Could Break

    These holes are usually built into the design of the gazebo, so attempting to cover or plug the holes would lead to gazebo dysfunction.

    A gazebo without ventilation holes in a wind storm could knock the whole unit over, and one without leak holes can cause the whole structure to collapse due to the weight of the rain in one bad spot.

    Prolonged water exposure to certain parts of the gazebo can also lead to rust, rips, tears, and leaks.

    How Many Holes Are Required in A Gazebo?

    Generally, you will see that most gazebos have four holes in their roof, one for each side of the structure, to allow for proper cross-breezes to flow through, making it suitable to use in all sorts of weather.

    This is entirely dependent on the model you are looking at, however, but most gazebos should have two to four built-in rooftop holes to ensure proper ventilation, circulation, and drainage.

    The design and structure of the gazebo should indicate how many holes are needed to ensure proper drainage and ventilation.

    Final Words:

    The key to having a gazebo that will withstand prolonged exposure to the elements is purchasing one that has built-in rooftop holes that will allow for relief from wind pressure, bring in a breeze for air circulation, and for proper water drainage.

    The best gazebo design that allows for ventilation would be a two-tier tent design, with the topmost part of the peak featuring ventilation screens with its own awning to avoid water from getting in, while still allowing wind to pass through and provide circulation inside the structure.

    Because the wind is passing through the peak, it is less likely for the wind to put pressure against the walls of the gazebo and topple over.
