I’m looking to reshingle my roof soon. I have laid shingles before, but never had to flash a chimney. My chimney meets my roof at the gable end and is only on one side of the gable, it doesnt go up to the ridge. How do I flash this? There are only 3 sides that meet the roof.
Michael,
You will need to start your step flashing that the bottom of the chimeny, and then work your way up. The top flashing piece (top of the chimeny) should extend up the slope at least 18 inches, and wrap around precenring step flashing. Then lay wour shingles over the flat (on the roof part), leaving at least 6 inches clearance between chimney, and the shingle above it.
Seal under the first shingle above the chimeny.
Hope this makes sense … try this video as well: https://www.youtube.com/watch?v=1RxsQRDyfNQ
