Ways to Install Chimney Flashing
Chimney flashing – A fireplace provides any room in the house with a warm atmosphere the whole family can enjoy. That enjoyment will be short-lived, however, if your fireplace starts leaking. Moisture from a dripping fireplace can damage wood beams and joists in the ceiling and at the same time leave an unsightly water stain on your ceiling. Michigan State University points out that if your fireplace exhaust is the result of improperly installed or worn intermittent, replacing the blinker not only stops the leak, it extends the life of your fireplace.
Lift the nails holding the shingles around the fireplace with the hammer claw. Because the same set of roof studs penetrates two tiles in each row, two tiles must be levered on all four sides of the chimney to expose the old flicker. Lift and remove the old blinker using the hammer claw. Use the old flicker as a pattern for cutting back flicker. Mark the cut lines and curve each piece of the new one for chimney flashing with a permanent marker.
Clamp each piece of blinking to a 2 x 4 block of wood with metal clamps. Place another 2-by-4 wooden block over the flicker and hit it with a hammer. This doubles the flicker of a perfect 90 degree angle. Align the curve on each piece of chimney flashing with the slot where the fireplace meets the ceiling. Slide a tile over the blinking until the edge of the tile is flush with the groove between the ceiling and the fireplace.
