Weather is unpredictable and out of your control. However, it can be extremely harsh and unforgiving. Your home is one of the biggest investments you can make, so you want to ensure it is well-protected against the weather elements and conditions.

What is the WindTripper

WindTripper was developed to solve the issue of roof wind damage that can occur from thunderstorms, hurricanes, tornados, and similar weather concerns. Whenever strong, severe, and high winds, your roof becomes a major target for structural damage.

When the winds blow, they immediately go to the edges of your roof, which are already loose and weak. Thus, if the wind is particularly fast and strong, it can cause serious and potentially irreversible damage to your roof. The worst-case scenario is losing your roof, which serves as your first line of defense against the outdoor conditions.

Upon looking deeper into this problem, we found that the root cause was the lift force of the wind on your roof and roofing material. Thus, we created the WindTripper, our patent-pending aerodynamic device that can protect commercial and residential roofs by keeping them secure and preventing them from lifting off, even against strong winds.


How the WindTripper Works

The roof of your home, building, or facility is designed like an airplane wing. When the wind blows into your property, it creates a low-pressure area over the roof. Under harsh conditions, the wind can gradually lift the roof and roofing material. The low-pressure area may also cause the entire roof to get detached from the supporting frame.

The WindTripper attaches to the edges of the roof–the most vulnerable area–and contains a spoiler that rests against the roof fascia. The spoiler will rotate to a deployed position upon detecting the increase in wind speed. With the deployed position, the spoiler will rotate such that it extends the airflow over the roof and prevents wind from lifting the roof off.

Along with this, there is an overhang surface that presses down on the roof to keep it stable and secure in its position. Once the wind speed decreases, the spoiler returns to its stowed position.

Overall, the WindTripper is designed to reduce wind damage by minimizing the effect of the winds on a roof. In addition, it protects your home from the potential loss of a roof by disturbing the airflow around the area. This way, the roof will not easily lift off the sub-roof.

Tested and Proven to Protect Against Wind Damage

We have conducted various tests to demonstrate how our WindTripper works and how its design can be used to combat roof wind damage.


Tuft Testing

We started by installing the WindTripper in a 12:1 scale model building constructed with the standard sills, sheathing, and trusses you will find in normal buildings. The roof was placed on the building sidewalls, and the WindTripper spoiler was placed in the area closest to the wind source.

We then used a blower to mimic the airflow of wind. The blower speed was set to a variable speed with a 50:1 ratio, and we made sure to monitor the output with a meter. When the spoiler was in a stowed position, the airflow pattern was smooth. It is similar to the design of an aircraft wing, which is meant to produce maximum lift.

However, our goal is to minimize roof wind damage, so we try to avoid this lift. After rotating the spoiler into its deployed position, we saw a disturbance in the airflow and its lift over the roof. Overall, there was a reduction in the lifting force caused by the blower, which indicates that the wind would need to be much stronger and faster to lift off your roof structure. Thus, the WindTripper was successful in mitigating the wind damage.

Smoke Testing

Using a similar setup as our tuft demonstration, we also conducted a smoke demonstration. The smoke is released from a pipe under pressure, then enters a slip strain from the fans and blows off the roof. This test allowed us to assess the aerodynamic effect of the WindTripper.

When the spoiler was in its stowed position, the WindTripper stayed attached to the roof. This is because wind flows along the roof, resulting in airflow that creates lift and tends to grab and displace materials in the roof like the shingles.

Once the spoiler was deployed, the airflow was separated from the roof. The smoke noticeably tumbled and dissipated above the roof structure, indicating a major change in airflow. In addition, here was little to no surface contact on the upper half of the roof, which helped reduce the lift and consequent upper pull on the roof and roofing material.

As you can see from our demonstrations, the WindTripper can prevent wind damage by changing the airflow such that it destroys the aerodynamic lift created by the low-pressure area over your roof. This way, your roof will stay attached to your home, and it stands stronger against the harsh pull of the wind.
