Roof Flashing Techniques for Leak-Free Roofs

Proper roof flashing techniques are crucial to preventing leaks and water damage. By using the right methods, you can effectively seal vulnerable areas and keep your roof secure for years.

Wrapped Corner Method

The wrapped corner method is a common and effective technique for flashing exterior corners. It works well for both DIYers and professionals.

Steps for the Wrapped Corner Method

• Position the Flashing Under the Weather Barrier
  Place the flashing beneath the weather barrier for optimal protection. For chimneys, secure the flashing as high as possible.
• Run the Base Flashing
  Extend the base flashing 4 to 5 inches beyond the dormer and bend it to match the dormer edge.
• Notch the First Step Flashing
  Cut and notch the first step flashing, leaving a 1-inch flap. Bend this flap around the dormer front.
• Continue with Step Flashing
  Layer shingles and add step flashing above each row, ensuring each layer overlaps securely.
• Apply Caulk
  Seal any small gaps with caulk to prevent water infiltration.

Soldered Corner Method

The soldered corner method offers superior durability and eliminates leaks at caulked joints. While more complex, this method ensures long-term protection.

Steps for the Soldered Corner Method

• Measure and Order Custom Flashing
  Measure your roof slope and order a custom copper flashing for easy soldering.
• Lay the Flashing
  Position the soldered flashing securely at the corner and nail it in place.
• Secure the Lower Edge
  Nail the lower edge if needed and seal nail heads with silicone.
• Add Shingles and Step Flashing
  Continue layering shingles and step flashing to ensure complete coverage.

Conclusion

Both roof flashing techniques provide reliable protection. Choose the wrapped method for a faster solution or the soldered method for maximum durability. For more tips and insights, explore more news on this website.
