Roof flashing is an essential component of your roofing system, designed to prevent water from seeping into vulnerable areas, such as around chimneys, vents, and valleys. Proper installation of roof flashing ensures that your home stays protected from leaks and water damage. However, improper installation is a common issue that can lead to costly repairs down the road. In this blog, we’ll highlight some of the most common mistakes to avoid when installing roof flashing.
Incorrect Flashing Placement
One of the most common mistakes is improper placement of the flashing. Roof flashing should be installed in areas where the roof meets a wall or another surface, such as chimneys, skylights, or vents. If the flashing is installed too far away from these points, water can easily slip underneath, causing leaks. It’s essential to place flashing at the right angle and position to effectively direct water away from these vulnerable areas.
Using the Wrong Type of Flashing
Roof flashing comes in various materials, including aluminum, copper, and galvanized steel. Each material has specific uses depending on the roof type and climate conditions. Using the wrong type of flashing can result in premature corrosion or ineffective waterproofing. For example, aluminum flashing might not be the best choice in areas with high humidity, as it can corrode faster than other materials. Always consult with a roofing professional to determine the best flashing material for your specific needs.
Not Securing Flashing Properly
Flashing must be securely fastened to prevent it from shifting over time. If it’s not nailed or sealed tightly, it can shift or become loose, creating gaps where water can enter. This mistake is particularly common around areas that experience high winds or storms. Be sure to fasten flashing properly with nails or screws and use a high-quality sealant to ensure a tight bond with the roof.
Overlapping Flashing Incorrectly
Properly overlapping roof flashing is crucial to ensuring water doesn’t sneak under the edges. If the flashing pieces aren’t overlapping enough, water can easily find its way through the gaps. On the other hand, overlapping too much can create a bulky area that traps water, leading to potential damage. The overlap should be just right to ensure optimal water runoff.
Neglecting to Inspect Flashing Regularly
Even after a successful installation, flashing can wear out over time due to exposure to the elements. A common mistake is neglecting to inspect your flashing regularly for signs of damage, rust, or wear. Performing annual checks will help you spot issues early on, preventing small problems from becoming larger, more expensive repairs.
Incorrectly Cutting Flashing
Properly cutting flashing is crucial for a watertight seal. If flashing is cut incorrectly, it can leave gaps or weak spots, leading to leaks. Using the wrong tools or not following the correct measurements can lead to uneven edges and poor-fitting flashing. Take your time when cutting the flashing, and ensure it fits snugly against the roofline and other components.
