[Shop-talk] building off of a vinyl siding wall

[Pat Horne]

John, several options bit you should run them by your local building officials. 

1. Remove the siding where the roof/awning is to be attached & mount the edge of the roof/awning to the sheathing. You might need tar paper or a membrane behind it. Put flashing behind the upper siding & onto the roof/awning. 

2. Drill some oversized holes through the siding & add spacers through the holes & secure the roof/ awning with lag bolts. There should be an air space between the siding & the roof framing. Flash as above. 

Peace,
Pat

we built an addition onto the house and it's covered in standard run of the mill vinyl siding.  Off that we built a 12wx10d p.t. deck.  The deck is accessed by a double French door with only one moving door.  I either want to
add an awning over the door or maybe cover the entire deck with a roof...  The vinyl siding copies lap siding and doesn't offer a nice flat surface to attach a header to.  What is the approved method for attaching something
permanent to a vinyl sided wall.  There is particle board beneath the siding and of course it's a studded wall so I have a sound surface to use but don't know about the siding  and attaching over it...  Suggestions ??  the pic is
not the actual wall just a sample of what it is.
