While flashing is designed to prevent water from getting into your roof, it is possible to deteriorate and cause a leak to happen. If you have water getting into your home from where the flashing material is falling apart around a pipe, here are some tips for replacing the flashing material.
Verify Where The Leak Is Located
You should start by trying to confirm where the water is getting into the roof. If you have any sort of ventilation pipes that stick out of the roof, it is likely that water is getting in around these places. Look at the flashing material to verify its condition. Is it detached from your roof or rusted? Is there rubber that is brittle and falling apart? If so, this could be where the water is getting in. Go into your attic and verify that you see water or stains beneath this part of the roof.
Removing Shingles Around The Area
All of that flashing material goes underneath the shingles that surround the pipe. If you need to replace any flashing, it will require that you remove those shingles in the immediate area. Make sure that you have additional shingles on hand so that you can immediately replace the material with new ones.
You can actually loosen the tabs located on the upper portion of shingles by using your putty knife. Work it around the top edge of your shingles to loosen them. These shingles along the top near the pipe are likely attached with roofing cement since nails cannot go through the metal flashing material. Once the first row or two of shingles are loosened, you can remove lower rows of shingles by prying up the nails. It will help to have a claw hammer to pull up the nails as cleanly as possible.
Removing and Replacing Damaged Flashing
Flashing can be removed in a similar matter, by using a claw hammer to pull back on the material. There may be nail securing the flashing in place, which will require the claw hammer to pull the material back and remove the nails. The old flashing material can either be broken off the pipe or slide off the top.
The new flashing material should slide back over the pipe, where it will need to be secured with nails or roofing cement.
Now you can move forward with securing your new roofing shingles in place around the pipe flashing. The bottom rows of shingles can be nailed into the surface of the roof, but the ones extending above the pipe will need to be secured with roofing cement.
