How to build a lean-to is what interests lots of homeowners, who need extra room. Surprisingly, but to build it one doesn’t need to possess any special knowledge. However, there are a few things you are to be aware of.

Make a Plan

In order to succeed in building a proper lean to you are to decide on how the lean should be constructed. Figure out as to what the lean is going to be constructed to.

Installing the Support Header

This is what you are to start with right after planning. The end of the header must set back from the edge of the building you are going to attach the lean to. Always consider the thickness of the trim and siding. Your task is to mark the location of the header’s end. Make sure that the header is level end-to-end and then fasten it in place with lad screws through the siding and right into the studs of the building. Drop a plumb line from the header’s corners and mark the locations on the bottom of the building. This will definitely help in determining the support posts’ location.

  • the distance between the 2 plumb-line marks for the carport’s length

  • between the two stakes
