Most people often miss this... | Deck Flashing

When adding a deck to a house, the flashing is often left out. It is a very important step, nonetheless!

I'll show you how to properly flashing the deck ledger board, so that you can rest assured that your deck won't rot the framing on your house over time.

Deck flashing or Z flashing is readily available at a Home center and will save you lots of problems later.

Finally a good video on flashing a deck ledger board. Thanks.

Thank you- Short & Sweet! Great video without all the fluff. This describes what I’m up against, except my door is above the ledger board. I’m dealing with water damage as the previous owners didn’t use flashing.

Thanks for your short video with useful information. Much appreciated.

I have an all brick, 60 yo house with a back deck that was built properly and per code 20 years ago. The boards & railing were removed 2 years ago to replace. The base frame was in great condition so waterproofing tape was installed over the frame boards and new boards and rails put on. I had an inspector out yesterday for something else and he was commenting on the deck and lack of flashing, saying water could seep in between the board and brick wall without flashing.

I pointed out that the soffit above covers that space. It was raining at the time and I pointed out that the deck board that runs along the house is completely dry while the other boards are wet. Code did not require flashing when the deck was built. He told me to put caulk between the board and the brick since there is no flashing. I'm searching online to learn if this is advisable. I've never had water seep in there but I'm fine with running some caulk along there if advisable.

Nice tips. The people who built my deck did not install any ledger board flashing and fortunately there has been no water infiltration since built about 24 years ago because they silicone the bottom of the vinyl siding to the deck board; shiiiisters. I found this issue because I had to remove 6 deck boards to dig a trench to apply termiticide under the deck. I also found they did not use corner bracing on a few side boards and only nailed the one board to the house (no lag bolts). I am now checking for other short cuts the builder took and making corrections. The inspector obviously missed these errors. Dam shiiiisters.

Exactly what in dealing with. Thanks for the advice!

This literally answered all my questions!

Buying a house and my inspector told us about "flashing". I had no idea what it was. Apparently the builders of the house we are buying neglected to install flashing between the butt joints of our siding (hardie wood plank).

They said we could either chalk it, as a stop gap for now which is the "wrong way to do it" or we could just try sliding some flashing behind after lifting up the siding.

Thanks for this video! Appreciate it!

Vinyl siding is not water-proof. If you don't have house wrap, which you should, you need an ice and water membrane.

Great video thanks. Our wall is pebbledash, not timber, and we have water penetration indoors in heavy or prolonged rain. There's no flashing I can see so water gets in easily.

[sylvaingauthier]

Thank you so much, just what I need. I will do the same way you did it . :)

[llahsramavt]

Good video. It would be great if you showed how to put the siding back also. Thanks.

[GTOoo]

And then do you put another layer over that flashing too?

[nicholasglasgow]

Can you show the install of the vinyl siding? You mentioned it in your video but never showed it. Good video. Thanks.

[debuenzo]

Shouldn't that flashing go behind the tyvek against the sheathing?

[Matt_justlikethat]

U have to flash the ledger board under the siding. A 6” pc of z flashing under siding attached to sheathing, ice hard against, an down an over top of ledger.

How do you re-attach the bottom piece of siding? Since the siding gets nailed at the top and the rest of the siding over lap each other then how would you nail it back up?

[rsmail]

I dont like this flashing with turn down edge directing water to end grain joist.

[Muuuzzzi]

So the water can get behind vinyl siding?
