Trying to add perpendicular addon to our back patio. Need help please.

[65Shelby]

Mornin' guys.  Trying to draw up an addon roof to our existing patio cover.  Ive viewed a few videos and tried adding a couple rooms but my roof always ends up looking like a leanto roof on one side.
Id like it to have a gabled end with a small slope to maintain roof line and stay under the window.
What Im doing:
- Create 3 external walls off the existing posts.
- Make room "Patio"
- "Gable" roof the end of the roof

Red drawing is what Id like, but this is my end result...  I know you guys are busy, appreciate any pointers you can offer.  Thank you in afvance.

that looks like the left wall is not set to hip, and the front wall is not set to gable. you might need to post the plan

Change the pitch on your new 3 walls to 2/12.  That should keep you under your other windows.  Slowly raise pitch until it is the max height you want it to be. (Pitches don't have to be whole numbers, FYI)

 

Second, draw the room 2' to the right of where you want it to be.  This will help you get the roof right, then you can move the walls 2' left once you like what you see.

 

Third,  keep the new room separate from the existing porch.  You need to keep the original left wall a gable and the new left wall needs to be hipped.  Keeping the existing front porch wall there makes sure the change in roofing stays aligned.

Thanks everyone.  Will try all of these mentions this weekend.

I agree with @JiAngelos third comment.  It appears the new 'room' is adopting the wall from the previous patio and somehow integrating the height of the whole house.  I did try the 'build off' method and it seems to be close but when I move and tie them back to the posts the wall goes crazy again.

@SHCanada2I am almost certain those walls are hip and gable, respectively, but will double check this weekend.  Thank you.

Thanks again guys.  Used the above recommendations and got pretty close.  Close enough to submit the 'idea' to Kootenai County now.
