Roof flashing is a crucial component of your roof that helps prevent water from entering your home. When roof flashing fails, it can damage both your home’s interior and exterior. That’s why understanding it’s important to know what causes its failure and what to do in case that happens. Our roof repair team at Tri-County Contracting shares a guide to help you.
What Is Roof Flashing?
Roof flashing refers to a thin sheet of metal installed around joints and gaps on the roof to protect your home against water infiltration. It is used to seal the bases of chimneys, vents and skylights, as well as installed on certain points where two roof planes meet.
The most commonly used materials for flashing are galvanized steel, copper and aluminum. When correctly applied, it acts as a barrier between water runoff and your home’s framework, protecting the building from damage caused by rainfall and melting snow.
Common Causes of Roof Flashing Failure
It’s important to note that roof flashing may fail for a variety of reasons depending on the material used and environmental factors. The most common causes are age, neglect, and improper installation. Due to moisture exposure and temperature extremes, galvanized steel and aluminum can corrode over time. Copper is less likely to corrode but can contract or expand in extreme weather situations, impacting its effectiveness as an effective barrier against water infiltration.
Shingles and other materials surrounding the flashing may blister or be peeled back, indicating flashing failure. The gutters, windowsills, and downspouts should also be inspected for signs of water infiltration. This includes stains on walls or floors that may indicate water leakage from the roof into the home’s interior, particularly during heavy rainstorms.
What to Do if Roof Flashing Fails
If you suspect your roof flashing has failed, it becomes crucial to respond quickly. A thorough inspection of the surrounding area should be done in addition to repairing or replacing the flashing. This is to identify any other areas where water may have seeped through. If these issues are ignored, things could deteriorate until you face a complete roof replacement instead of a minor repair.
How to Prevent Roof Flashing Failure
Keeping up to date with maintenance and inspecting for any signs of wear and tear such as loose shingles should also be done to minimize roof flashing failure. Plus, checking for any debris buildup can help ensure proper water flow in the event of a storm. Proper maintenance and repairs will ensure your roof’s integrity over the years.
