Hey there! As a supplier of External Corner Flashing, I've been getting a lot of questions lately about how to measure the effectiveness of this essential roofing component. In this blog post, I'm going to share some insights and practical tips on this topic.
Why Measuring Effectiveness Matters
First off, let's talk about why it's so important to measure the effectiveness of external corner flashing. External corner flashing is designed to protect the corners of a building from water damage. If it's not working effectively, water can seep into the building, causing all sorts of problems like mold growth, rotting wood, and structural damage. By measuring its effectiveness, we can ensure that our customers are getting the best protection possible for their buildings.
Key Factors to Consider
There are several key factors to consider when measuring the effectiveness of external corner flashing. Let's take a look at each of them.
1. Water Resistance
The primary function of external corner flashing is to keep water out. One way to measure its water resistance is through a water test. You can set up a simulated rain situation using a hose or a sprinkler system. Direct the water at the external corner flashing for a set period, say 15 - 20 minutes, and then check for any signs of water penetration inside the building. If there's no water seepage, it's a good sign that the flashing is doing its job.
Another aspect of water resistance is the durability of the flashing material. Some materials are more resistant to water and weathering than others. For example, high - quality resin - based flashing can offer better long - term water resistance compared to cheaper alternatives.
2. Sealing Performance
A good external corner flashing should form a tight seal at the corners. You can visually inspect the seal to see if there are any gaps or openings. If there are gaps, water can easily get through. You can also use a smoke test to check the seal. Light a smoke source near the flashing and see if the smoke is drawn into any gaps. If it is, then the seal needs to be improved.
3. UV Resistance
External corner flashing is exposed to sunlight, and UV rays can cause damage over time. UV - resistant materials will last longer and maintain their effectiveness. To test the UV resistance, you can place a sample of the flashing in direct sunlight for an extended period, say a few months, and then check for any signs of degradation, such as cracking, fading, or brittleness.
4. Structural Integrity
The flashing should be able to withstand the forces it's subjected to, such as wind, snow, and the weight of roofing materials. You can check the structural integrity by applying some pressure to the flashing. For example, gently push on it to see if it bends or breaks easily. If it does, it may not be strong enough to provide long - term protection.
Tools for Measuring
There are a few tools that can be helpful when measuring the effectiveness of external corner flashing.
1. Moisture Meters
Moisture meters are great for detecting water penetration. You can use them to check the moisture levels inside the building near the corners where the flashing is installed. If the moisture levels are higher than normal, it could indicate that the flashing is not working effectively.
2. Pressure Gauges
Pressure gauges can be used to measure the pressure exerted on the flashing by wind or other forces. This can help you determine if the flashing is strong enough to withstand these pressures.
3. Thermal Imaging Cameras
Thermal imaging cameras can detect temperature differences, which can be an indication of water leakage. If there's water seeping through the flashing, it will cause a temperature change that can be detected by the camera.

How to Improve Effectiveness
If you find that your external corner flashing is not as effective as it should be, there are a few things you can do to improve it.
1. Proper Installation
Make sure the flashing is installed correctly. This includes ensuring that it's properly aligned, sealed, and secured. A poorly installed flashing is more likely to fail.
2. Regular Maintenance
Regularly inspect the flashing for any signs of damage or wear. Replace any damaged parts as soon as possible to prevent water leakage.
3. Upgrade the Material
If your current flashing is not performing well, consider upgrading to a higher - quality material. Our resin - based flashing is a great option as it offers superior performance compared to many other materials.
Conclusion
Measuring the effectiveness of external corner flashing is crucial for ensuring the protection of your building. By considering factors like water resistance, sealing performance, UV resistance, and structural integrity, and using the right tools, you can accurately assess how well your flashing is working.
