How to Flash a Roof Vertical Wall

Flashing a roof vertical wall is an essential step in preventing leaks and ensuring the longevity of your roof. Here's a comprehensive guide on how to do it:

Materials You'll Need:

Roof flashing (e.g., step flashing, counter flashing)
Nails or screws
Caulk or sealant
Hammer or nail gun
Caulking gun
Utility knife

Step 1: Prepare the Wall Surface

Clean the wall surface thoroughly to remove any dirt, debris, or old flashing. Inspect the wall for any damage or gaps and repair them as needed.

Step 2: Install Step Flashing

Cut step flashing to the desired length, ensuring it extends at least 4 inches past the wall surface. Slide the flashing up under the roofing shingles and nail it to the wall.

Step 3: Install Counter Flashing

Cut counter flashing to a slightly wider width than the step flashing. Bend the bottom edge of the counter flashing at a 90-degree angle to form a drip edge. Place the counter flashing over the step flashing and nail it into the wall.

Step 4: Caulk Joints

Apply a generous bead of caulk along all seams and joints between the flashing components and the wall. This will seal any gaps and prevent water penetration.

Step 5: Overlap Flashing

Install multiple rows of step flashing and counter flashing, overlapping them by at least 4 inches. This ensures proper water drainage and prevents leaks.

Step 6: Secure the Flashing

Nail or screw the flashing securely to the wall and roofing shingles. Ensure all nails or screws are countersunk slightly below the surface.

Tips for Success:

Use galvanized or stainless steel flashing for durability.
Install the flashing in dry weather to prevent water damage.
Inspect the flashing regularly for any damage or wear.
Have a professional roofer inspect and repair the flashing if you encounter any problems.

Flashing a roof vertical wall is a crucial aspect of roofing that ensures a leak-free and long-lasting roof. By following these steps and tips, you can effectively protect your home from water damage and enhance its overall integrity.
