What Is “Step Flashing” And How Does It Prevent Leaks?

When it comes to protecting your home from the elements, the roof is one of the most important components. One of the most critical elements in preventing leaks in a roofing system is step flashing. So, what is step flashing and how does it prevent leaks? Let’s take a closer look.

Step flashing is a component of a roofing system that is installed around vertical surfaces, such as chimneys or skylights, where the roof meets the wall. It is typically made of metal, such as aluminum or copper, and is installed in a step-like pattern, with each piece overlapping the one below it. The step flashing is integrated into the roofing shingles, with each piece tucked under the shingle above it and extending up the vertical surface.

The purpose of step flashing is to direct water away from the vulnerable areas where the roof meets the wall. Without proper step flashing, water can seep into the gap between the wall and the roof, causing damage to the structure of the home, and leading to costly repairs.

Step flashing is critical in preventing leaks because it creates a barrier that directs water away from the vulnerable area, preventing it from seeping into the roof or wall. The overlapping design of the step flashing creates a seamless surface that allows water to flow freely without getting trapped in gaps or crevices.

In addition to its protective properties, step flashing also provides a decorative element to the roofing system. It is available in a variety of colors and finishes, allowing it to blend seamlessly with the roof and wall materials.

In conclusion, step flashing is a critical component of a roofing system that plays an essential role in preventing leaks and protecting your home from water damage. Proper installation and maintenance of step flashing, along with the other components of your roofing system, can help ensure the longevity of your roof and the safety of your home. Be sure to work with a licensed and experienced professional to ensure that your roofing system is installed properly and maintained regularly.
