7 Flashing Installation and Repair Mistakes to Avoid

The main purpose of the flashing is to redirect water away from vulnerable areas of your roof. However, even small flashing installation and repair issues can put your roof at risk. In this blog post, roof repair contractor Christian Brothers Roofing discusses seven common flashing mistakes you need to avoid.

1. Using Incompatible Materials

For seamless integration and durability, invest in compatible materials for all your roof’s components, including the flashing. For instance, if you use copper flashing with aluminum roofing, galvanic corrosion may occur, which weakens the roof’s structural integrity.

2. Improper Sealing

While proper sealing is crucial to prevent water infiltration, some common sealing mistakes can put your roof at risk. One such error is using insufficient or low-quality sealant. Additionally, improper application or uneven sealing can create vulnerable spots, allowing water to seep through. To avoid these issues, ensure your flashing is effectively sealed to provide long-lasting protection for your roof and home.

3. Incorrect Flashing Placement

Flashing should be installed at all roof penetrations, such as chimneys, vents, and skylights, as well as in areas prone to water collection, including valleys and eaves. Otherwise, this can lead to water damage and a reduced roof lifespan. For more effective roof protection, your flashing should be installed by a professional.

4. Insufficient Overlap

To drain water and prevent leaks, flashing pieces should overlap by at least three inches. The upper piece should extend over the lower one to allow water to flow downward and away from the roof. Insufficient overlap can result in water seeping through the gaps, leading to leaks, water damage, and costly repairs.

5. Ignoring Manufacturer’s Instructions

Following the manufacturer’s instructions for flashing installation and repair is critical for optimal performance and durability. Ignoring these instructions can result in improper installation, compromised effectiveness, and the potential voiding of warranties. Make sure the roofer you hire for the installation or repair adheres to the manufacturer’s guidelines for best results and long-lasting protection.

6. Hiring Unqualified Contractors

Entrusting your flashing installation and repair to a reputable roofer is imperative for ensuring the job is done correctly and securely. Hiring unqualified contractors can lead to errors, inadequate work, and potential damage to your roof.

7. Neglecting Regular Maintenance

Regular roof maintenance is essential for maintaining the effectiveness of your flashing and overall roof health. Inspecting and repairing your flashing as needed prevents small issues from escalating into major problems. With this, you can be sure that your roof is in top condition.

Proper flashing installation and repair are crucial for protecting your roof from water damage and ensuring its longevity and weather performance.
