Home » Blog » Hurricane Impact Windows: Can They Protect Your Roof From Blowing Off?

Impact windows are designed to protect your home from hurricanes, but can they also be used to keep your roof on during a storm? The air pressure under the roof is an important role in why roofs blow off during a storm.

Storm force winds push into homes and upward towards roofs, while wind, rain, and sometimes debris hit it from the outside. The resulting force lifts the roofs off, and once that happens, everything inside will be destroyed.

All it takes is a broken window or door to cause a massive change of pressure in your house. Impact windows are designed to keep air pressure equal between the outside and inside so that your roof can’t be lifted off.

How are Roofs Completely Destroyed by Hurricanes

One of the first steps people take when preparing for a hurricane is securing the windows and dorms of your home. This can include adding shutters to windows and doors, or installing impact windows if you are able. The reason for securing this part of your home first is because it is the most vulnerable to hurricanes.

Another important and vulnerable part of your home to protect is your roof. Roofs are vital for protecting you and your home from storms! They shelter both inside and outside parts of your property from water, wind, debris, rain, or anything else that might be in the air during a storm. How can this major part of your house get completely blown off despite the high winds that these storms bring?

When these intense and strong winds begin to enter your home, they may cause a change in air pressure. When the wind continues to enter your home, it will push upwards towards ceilings and rooflines which can be very dangerous for the entire structure of your home. The force from these winds will lift off roofs from homes destroying everything inside.

How Do Impact Windows Help

The single most important factor in hurricane protection is protecting all openings from being compromised, including windows. This is why people opt for installing hurricane impact windows in their homes. If your window breaks or shatters from the debris and wind, this is all it takes to cause a massive change of pressure in your house. Leading to more extensive damage.

Impact windows are made up of different levels of impact glass to protect your home from hurricanes and other storms. They are capable of withstanding up to +/-100 pressure, in turn, keeping your home and family safe. The impact glass help protect your windows from breaking due to outside forces. Thus, keeping the air pressure equal in your home, and your roof safe.

Other Ways Impact Windows Protect Your Home

Not only do impact windows protect your home from potential hurricane damage, but it helps in many other ways.

  • Energy saving
  • Noise reduction
  • Burglar resistant
  • Increase property value

Energy Saving

Installing impact windows in your home helps save money on the energy bill every month. The impact glass blocks ultraviolet light, heat, as well as cold air from coming in through your window. This means you turn on the heater or AC less often because of the reduced energy loss into your home thanks to these windows.

Noise Reduction

Another way your home can benefit from impact windows is by reducing noise. They are built to decrease external noise by as much as up to 65%.  This is because impact glass absorbs much more energy than standard glass does, which reduces the amount of sound passing through it. Thus, allowing you to enjoy the peace and quiet from the outside world in the comfort of your own home.

Burglar Resistant

Impact windows can also be used as burglar-resistant protection for your home. They are designed to resist break-ins from impact points and have a tough double-glazed safety film that is virtually unbreakable.

Most impact windows are made of either vinyl or aluminum. Vinyl impact windows come tinted with different colors for an added touch of personal style while also providing privacy. 

Property Value

Impact windows can make a big difference when it comes to the property value of your home. Investing in this product not only brings more value to your house from a safety standpoint but also brings up curb appeal.
