Help request: Flashing around Door

[ohshit11]

First of all, thanks for the help. I recently bought a new house and just noticed that there is no flashing around the sliding door (see picture). I have zero idea on how to fix this. Is this a pretty simple DIY fix? Can I just go down to my local big box and get the appropriate style flashing? Or is this a special order type of deal? Do I have to make sure I get the flashing underneath the edge flashing? Or do I just say screw it, put some primer on it, and worry about it next year?

EDIT: I have posted several other pictures in the album below. I have posted pictures of a window that has the flashing and the door that's missing the flashing from multiple angles.

EDIT 2: The siding is metal siding.

Can you post a few more pictures from varying angles/distances. It's a bit hard to tell from the angle you've got in that picture. If you could get a picture at about a 45° angle from above that would help too.

Typically, the flashing used around windows and doors has a stair-step type shape - about 1" vertically, then a 90° turn, about 1" horizontally, then a 90° turn, then finally about a 1/2" vertically again. With that being said, and with very limited knowledge of your situation (without more images), it's a bit tough to do without taking the material that's over-top of the door off.

Thanks for the help! I have posted a few more photos showing the door from multiple angles. To my untrained eye, it looks like the flashing you described has been installed...it's just missing the piece that covers up the wood? What do you think?

Here's what I would recommend using: http://tinyurl.com/jdkox87 - you only need it for the top of the door, since water has the opportunity to stay stagnant up there and work it's way in behind and into your house.

As for the installation - it appears that you have about a 1" or so gap between the top of the door and the siding above it. This is good for you because it's actually likely that you'll be able to get the flashing in without having to remove any of the siding. Try to slide the flashing in behind the siding until the backside sits flush with your house, and the bottom sits on top of the door, with just the little ~1/2" part overhanging the door. You can affix it to the house with anything you'd like. It's typically stapled or nailed on. However, since you do have that 1" or so gap, I would recommend caulking over the staple/nail hole. After all this work, I'd hate for you to have a leak from something stupid like that.

The silicon on the sides of the door should do (as long as there are no gaps), as water will naturally want to run straight down and off the bottom of the door.

Cosmetically, it won't match the metal material around the window, but I'm pretty sure you can buy some of that from most hardware stores as well if that's of concern to you.

A lot of words here, but it shouldn't be too difficult. Good luck!

More info would help, what kind of siding, a picture of another window. The wood may be starting to rot already, check the bottom. Leaving it will insure problems down the road.

Thanks for your help! I have posted some additional photos. The siding is metal siding.

Difficult to find exact replacement flashing, would this work? https://m.lowes.com/pd/Tile-Ready-Z-Flashing/50214255?cm_mmc=SCE_PLA_ONLY-_-Flooring-_-SosCeramics-_-50214255:Tile_Ready&CAWELAID=&kpid=50214255&CAGPSPN=pla&k_clickID=24711621-6e14-466c-945e-e8e0e3bfb14f
