Step flashing is an essential component of roof flashing systems, providing effective protection against water intrusion for metal roofs. It's a critical element in ensuring the integrity and longevity of a metal roof.

Flashing installation involves placing individual pieces of step flashing along the intersecting areas of the roof, such as where the roof meets a wall or chimney. These pieces are typically made of metal, such as aluminum or galvanized steel, and are bent at a 90-degree angle to form an L-shape. This design allows the step flashing to fit snugly against the roof surface and the adjacent vertical surface, creating a watertight seal.

Proper flashing installation is crucial to prevent water from seeping into the roof and causing damage to the underlying structure. The step flashing should be securely fastened to the roof deck using nails or screws, ensuring it's firmly in place. It's important to overlap the step flashing pieces correctly to ensure water is directed away from vulnerable areas.

Regular flashing maintenance is also essential to prolong the life of the metal roof. Inspecting the step flashing for any signs of damage, such as rust or loose pieces, should be done at least once a year. Any damaged or deteriorated step flashing should be replaced promptly to maintain the effectiveness of the flashing system.

Valley Flashing

Proper installation of valley flashing is essential to prevent water leaks and other related problems. When installing valley flashing, it's important to follow specific guidelines to ensure its effectiveness.

One common problem with valley flashing installation is improper overlap. The overlapping of valley flashing sheets should be sufficient to provide a watertight seal. Insufficient overlap can lead to water seepage and damage to the underlying roof structure. It's important to carefully measure and cut the flashing sheets to achieve the correct overlap.

Another common issue is inadequate sealing. To ensure proper water protection, it's crucial to seal the edges and joints of the valley flashing. This can be done using sealant or adhesive specifically designed for metal roofs. Attention to detail during the sealing process is important to prevent any gaps or openings that could allow water to penetrate.

Additionally, proper alignment of valley flashing is crucial. The flashing should be positioned in a way that allows water to flow freely without obstruction. Any misalignment can lead to water pooling and potential leaks.

Regular maintenance and inspection of valley flashing is also important to identify and address any problems early on. Checking for signs of wear, damage, or deterioration can help prevent major issues down the line.
