Should I add another post to Patio Cover?
I have an extension cover over my patio that is supported by a beam made of 2 2x12 16 ft long. One end is supported by a hanging bracket to the house and the other by a wood post. So the spacing between support elements is 16ft, I am contemplating adding another post in the center of the span for safety and stopping deflection of the beam. My concern is that the wooden post may fail over time so with another post the cover would not collapse. The structures weight is easily carried by the supports today. Each corner needs to support approximately 1000lbs, the wooden post is rated for 3000lbs, two corners are attached to the house roof and one to the house. Am I being to cautious?
