Chimney flashing | Slate Roof

Flashing is used when the existing roof runs in to something, like a wall or a Chimney. Flashing is usually made of some kind of metal that is fabricated to fit against the wall or chimney to prevent water from running in between where the roofing stops, and the wall or chimney starts.

On most your slate and tile roofs they use 20 oz. copper for flashing. Slate and tile roofing systems last 50-100+ years so you need a metal that will compete with that long of a life span.

 In this picture you can see the existing slate around the chimney has been removed and the old flashing also has been removed. To the left of the chimney there is the tool they use to pull the nails out from a piece of slate to remove it, it is called a slate ripper and usually cost around $100.00 to purchase. Be careful when hiring a roofing contractor, to make sure he has a slate and tile background. A slate and tile roofing contractor will have these tools. A roofing contractor with no slate or tile history will not have these tools and do more damage then good.

 In this photo you can see the roofing contractor has finished fabricating the necessary copper flashing for the chimney and reinstalled the slate that was removed.

  
You can see where the previous contractor, kinda buggered up the mortar joints on the chimney. This falls under, making sure you hire a reparable slate and tile contractor. The one thing I like to see on a slate roof is a copper ridge cap! They look so much better but it might not be in every ones budget. In this photo you see the home owner has chosen not to use a copper ridge cap, which in that case the contractor will use tar to seal the top portion where the two sides meet.

  
The ridge looks a lot better once smoothed out. and from the next picture you can see that you can hardly notice it from the ground.
