Replacing awning on side door
I'm looking for a little construction advice. The side entrance to my house has an aluminum awning over it that has been beat up by years of ice and snow. This season it bent down far enough that the screen door hits it so it's time for it to go. I'd like to replace it with something more substantial, and I've seen some shed awning designs on other houses similar to mine, a 1920s American Foursquare. I think I can figure out the carpentry for the structure of the roof, but I'm stumped as to how to attach it and it's support brackets to the house. I have aluminum siding on the house that will have to be cut into to get to the structure and I'm not sure of the best way to do that and to make it all watertight again. Below are links to the photo of the current awning and a sketch of a design to replace it. (sorry I couldn't get the image uploader to work).
I figure I need to mount the equivalent of a ledger board on the side of the house and then build off of that, but I have no idea how to flash around it. Any advice or resources would be appreciated. Thanks.
Re: Replacing awning on side door
Building an overhang is a good project.
You can find plans on line, or you can create your own design.
Follow all construction principals, as you were building a deck, a patio cover, etc.
Flashing around the ledger and the roof: insert an angled L flashing under the siding and over the shingles.
