Roof flashing is one of the most important components of a roofing system, yet it’s often overlooked. This thin, weather-resistant material, usually made of metal, rubber, or plastic, is installed around chimneys, vents, skylights, and roof valleys to direct water away from vulnerable areas. When flashing is damaged or improperly installed, it can lead to leaks that compromise your home’s structure. Today, we at Skyline Designs Roofing & Restoration would like to discuss why fixing roof flashing is crucial and how to do it effectively.
Role of Roof Flashing
Flashing acts as a barrier against water intrusion in areas where the roof meets other structures. Without properly functioning flashing, rainwater can seep into the roof deck, attic, and even interior walls, causing extensive damage. Over time, exposure to extreme weather, temperature changes, and poor installation can cause flashing to deteriorate, leading to leaks that result in mold growth, rot, and structural weakening.
Common Causes of Flashing Damage
Several factors can contribute to flashing failure, including:
Corrosion – Metal flashing can rust or corrode over time, especially in humid or coastal climates.
Poor Installation – If flashing isn’t securely fastened or properly sealed, water can easily penetrate gaps.
Storm Damage – High winds, heavy rain, and falling debris can bend or dislodge flashing.
Age and Wear – Like all roofing materials, flashing deteriorates over time, leading to cracks or warping.
Improper Repairs – Using the wrong materials or sealing methods can do more harm than good.
How to Fix Roof Flashing
If you notice signs of flashing failure, such as water stains on ceilings, damp walls, or visible gaps around chimneys and vents, it’s important to address the issue quickly. Here’s how to fix flashing problems:
1) Inspect the Flashing. Carefully examine the flashing for cracks, rust, or loose sections. Check for dried-out or missing sealant, which can lead to leaks. If you’re unsure, a professional roof inspection can help identify issues.
2) Remove Damaged Flashing. If flashing is corroded, cracked, or severely damaged, it must be removed. Use a pry bar to lift old flashing carefully, being mindful not to damage surrounding shingles.
3) Install New Flashing. For metal flashing, cut a new piece to match the size of the damaged section. Secure it in place using roofing nails, ensuring it sits snugly against the surface.
4) Seal the Edges. Apply a high-quality roofing sealant around the edges to create a watertight barrier. Avoid using cheap caulking, as it may not hold up against the elements.
5) Secure with Roofing Cement or Screws. If necessary, apply roofing cement under the flashing to provide extra adhesion. For added security, use galvanized screws to hold it in place.
6) Test for Leaks. Once the repair is complete, spray water over the area to check for leaks. If water still seeps through, reapply sealant or consider professional help.
Preventative Maintenance
To prevent future flashing issues, schedule regular roof inspections, especially after storms. Keep an eye on potential trouble spots and replace aging flashing before leaks develop. Proper maintenance can save you from costly repairs and keep your home protected from water damage.
