9' garage door header


My 9' garage door solid header had rot on the right half which I removed.
The remaining header is 10"x10" on the left untrimmed side but narrows on the right side to a trapezoid measuring 10" vertical, 4.5" on bottom and 9.5" on top.
So the beam at the weakest point has at least the strength of a 5"x10" header.
Is this enough for a flat roof with max snow load of 1'. The narrowest spot in the header is five feet from the corner of the roof.

I understand you want to replace a rotting header. The rest I don't understand except that you aren't sure about size. Is there some reason you don't want to replace it with the same size that was there?

Replacing the header may not be necessary if the remaining header is adequate. We use over sized beams in Santa Fe for style. My hope is to build a false cover to conceal the missing portion which is about 25% of the cross sectional area of the header. Cost difference between this and replacement is about $300 vs $3000

OP: "Is this enough for a flat roof with max snow load of 1'." ---------- NO. Not when the builder used a minimum 10x10" header because he had to pass inspection or the Engineered plans called it out. You now have 1/3 as much left, how would that suffice?

"So the beam at the weakest point has at least the strength of a 5"x10" header." ---- A structural Engineer evaluated this? Or are you guessing?

1. Where are you located?

2. What is the load? Joist span? Trusses bearing- span? Rafters/ceiling joists? Storage on c.j.s?

Be safe, Gary
