How Do You Install Flashing On An Existing Roof?

There are a few ways to do the job, but flashing is important because it protects the roof and helps prevent leaks.

Step 1: Loosen the shingles.

Using a pry bar, pull back the shingles above and on both sides of the vent pipe. There’s no need to bend back the tiles beneath the pipe. You may bend them back by inserting a putty knife under the bottom of each tab and breaking the seal with it.

Step 2: Place the new flashing over the vent and into the correct position.

The flashing should be put beneath the top and side shingles but above the shingles below the vent pipe. You can turn the flashing as you drop it in position to make installation simpler. The flashing’s neck should fit tightly around the pipe.

Step 3: Hammer the nails into the top and sides of the flashing.

Ensure the top and side shingles are curved back, so you don’t accidentally nail through them. To seal the nail heads, use roofing cement.

Step 4: Hammer nails into the bottom edge of the flashing.

You must ensure the flashing is on top of the shingle beneath the vent pipe before driving the roofing nails into the flashing’s bottom edge. Apply roofing cement next to seal the nail heads.

Step 5: Use roofing cement to seal around the flashing’s edges.

Do not forget to use caution if you want to complete the task alone. We must emphasize this. Use nails made of the same metal as the flashing as well. This is crucial because different metals can interact and speed up corrosion.
