One of the most common causes of roof leaks is around the vent pipes. The reason for this is that the flashing (the metal trim that goes around the base of the vent pipe) is not installed properly or has come loose. If you have a leaky roof vent, the first step is to check the condition of the flashing. If it is loose, you will need to remove it and install new flashing.

To repair a leaky roof vent pipe flashing, you will need the following supplies:

– a ladder
– a putty knife
– a tube of roofing cement
– a piece of flashing (metal or rubber)
– a utility knife

1. Using the ladder, climb up onto the roof and locate the leaky vent pipe.

2. Use the putty knife to scrape away any old roofing cement that is around the base of the vent pipe.

3. Apply a bead of roofing cement around the base of the vent pipe.

4. Place the piece of flashing over the roofing cement. Use the utility knife to trim the flashing so that it fits snugly around the vent pipe.

5. Apply another bead of roofing cement over the top of the flashing.

6. Allow the roofing cement to dry for 24 hours before climbing on the roof again.

How do you seal roof vent pipe flashing?

1) Apply a thick bead of lap-seal caulk around the seam between the vent pipe and old rubber gasket.

2) Then run a second bead of caulk just below the first bead.

3) Slide the replacement rubber gasket over the pipe and press it down tight to the flange.

I’m going to use a lap seal caulking which is actually designed for rubber roofs. Okay, I’m going to put a little bit on here. I’m just going to smooth it out with my finger. I don’t want to put too much because then it will just run off the edge. And that’s pretty much it. It’s really easy to do and it should last a long time.
