Siding an old house #2 Flashing

Wow, look at the time!

It’s been more than a month since I’ve posted on my little project here at the Misadventures. No I haven’t run out of steam or money – yet. It’s just when the weather is good you make the best of it and go, go go.

So we’re getting the outside done before the cold weather returns this year – that’s my story and I’m sticking to it. Let’s talk about flashing, shall we?

First – there is a big difference between caulking something and flashing something. In my opinion always flash if you can – and throw a little caulk in there for good measure.

So here’s some flashing.

1 copper flashingNow like everything else I’ve gone overboard. These are copper head flashing that go over all the exposed windows. I had them fabricated from 16 ounce copper and soldered end caps. Typically an aluminum angle flashing is all you need.

2 flashing over windowsAll the windows that are exposed to rain get these. The top windows on the second floor won’t need the flashing because they are covered by the roof overhang.

3 copper nailsSo we grab a handful of copper nails – regular steel nails won’t work as they’ll react to the copper.

4 flashing nailedThe housewrap is cut to make a flap above the window so that the flashing will nail directly to the sheathing.

5 flashing tapedA piece of self adhesive flashing tape  is then placed over the copper and sheathing. Make sure the tape is compatible with copper.

6 flashing doneThe flap of  housewrap is taped over this. I’ll add felt and rainscreen over this before the siding is installed.

7 wall penetrationsAll of the wall penetrations also get their own little copper flashing. These are done a little differently because the rainscreen (the green stuff) has to be installed 1st.

8 light blockFor example this light block for a patio light. The block is made from 5/4 (1″) thick Azek surrounding a 4″ octagonal electrical box placed on point so the light fixture will mount correctly. The block sits on top of the rainscreen.

9 light blockFirst cut a section of the rain screen out above the block and cut a flap through the felt and housewrap.

10 light blockThese small flashings were made from strips of copper I cut and bent, tucking the sides in – not as fancy as the soldered window flashings, but they’ll work fine.

11 light blockFlashing is attached with copper nails.

12 light blockFlashing tape over that –

13 light blockThe flap comes down and the rainscreen is replaced and taped. The siding will be the next and final layer.

I know this was pretty boring unless you woke up in the middle of the night wondering how you were going to flash that wall penetration –

Well, now you know.

Oh, and one more thing -Some pretty things are getting done around this place – here’s a peek at the master shower under construction.

    • Hi Betty! I decided to have a pro do the tile work and it’s way better than I could do. The green stuff is GreenGuard – and you’re right – it is dimensional to allow moisture to drain from behind the siding.

    • Hi Jo – thanks for the flashy compliment! The tilers were here for nearly 3 weeks and they have another bathroom to tile.- it would have taken me months to do just one.
