Importance Of Correct Placement Of Step Flashing
Properly placed step flashing is paramount in preventing water damage to roofs. Step flashing is a type of flashing commonly used in conjunction with shingle-style roofing materials. It is installed along the vertical walls of the roof, overlapping each course of shingles.
When improperly installed or neglected, step flashing becomes susceptible to water infiltration. This can lead to leaks, rot, and mold growth. To avoid these issues, it is crucial to correctly position step flashing during roof installation or repair.
Using Kickout Flashing To Prevent Water Damage
One effective solution to prevent water damage and ensure proper drainage is the use of kickout flashing. Kickout flashing, also known as diverter flashing, directs water away from a vertical wall and into the gutter system. It is typically placed where a sloping roof meets a vertical wall and is bent to divert water onto the roof rather than allowing it to flow behind the siding.
By bending kickout flashing correctly, it can effectively protect against water intrusion and potential structural damage. The following steps will guide you through the process of bending kickout flashing using commonly available materials.
Options For Kickout Flashing Materials
Kickout flashing can be fabricated using different materials, including polypropylene, aluminum, or copper coil stock. Each material has its own advantages and may be chosen based on project specifications, budget constraints, and personal preference.
- Polypropylene kickout flashing is lightweight, budget-friendly, and resistant to UV rays.
- Aluminum kickout flashing is durable, lightweight, and corrosion-resistant.
- Copper kickout flashing, on the other hand, is renowned for its aesthetic appeal, longevity, and malleability.
