Roof Flashing 101: Expert Techniques for Repairing and Replacing Roof Flashing
Roof flashing plays a crucial role in protecting your Michigan home from water damage by creating a waterproof barrier between your roof and vulnerable areas like chimneys, vents, and skylights. If not installed or maintained correctly, damaged roof flashing can lead to leaks and costly repairs. Now, let’s break down the basics of roof flashing, common repair issues, and expert techniques for repairing and replacing it—specifically for Michigan homeowners.
What is Roof Flashing?
Roof flashing is a thin, weather-resistant material installed at joints, seams, and other areas of your roof that are prone to water intrusion. It helps direct water away from areas where it could otherwise seep in, protecting the roof structure and interior spaces. Common flashing materials include aluminum, copper, steel, and even rubber.
Common Types of Roof Flashing
Step Flashing: Typically used around chimneys and walls, step flashing is installed in overlapping pieces to ensure water is channeled away correctly.
Valley Flashing: Placed in the valleys where two roof planes meet, valley flashing helps water flow into the gutters.
Drip Edge Flashing: Installed along the edges of the roof, this Flashing directs water into the gutters, preventing water from damaging the fascia or soffit.
Vent Pipe Flashing: This is placed around pipes or vents that protrude through the roof, sealing the gap to avoid leaks.
Signs You Need Roof Flashing Repair
The first step in addressing roof flashing issues is knowing when repairs are necessary. Look out for these common signs:
Leaks in the Attic: Water stains or drips in your attic could indicate that flashing has failed.
Visible Gaps or Rust: Visibly separated, rusting, or otherwise damaged Flashing requires immediate attention.
Curled or Missing Shingles: Damaged flashing can cause shingles to lift or curl, exposing the roof to more water damage.
Mold or Mildew: If you see mold or mildew in your home, especially around chimneys, vents, or walls, your roof flashing may be the cause.
Expert Techniques for Repairing Roof Flashing
-
Patch Small Holes or Cracks
If your Flashing has small holes or cracks, you can often repair these with roofing cement or silicone caulking. This quick fix can prolong the life of your Flashing until a more permanent solution is implemented.
-
Replace Damaged Flashing Sections
Replacing flashing sections is often the best solution in more severe cases where the flashing is damaged, corroded, or missing. This involves removing any compromised sections and installing new flashing, ensuring it overlaps properly with surrounding materials.
-
Secure Loose Flashing
Loose Flashing can be re-secured with roofing nails or screws. Be sure to cover any nail or screw heads with a waterproof sealant to prevent water intrusion.

Seal Gaps Around Chimneys and Skylights
Proper sealing is crucial for areas around chimneys or skylights. Using flashing tape or roofing cement to secure gaps can help prevent water from seeping through and causing damage.
