Structural Integrity Assessment for Dormered Home

I need a professional to assess the structural integrity of my 48' home with a metal roof and three 10' dormers. I have basic sketches available. The assessment should focus on:

- Load-bearing capacity
- Wind resistance
Need to know what to change to make sure this is structurally sound. Construction of load bearing walls and is there a special ridge beam or brackets that would be required to maintain the structural load.

Ideal Skills and Experience:
- Licensed structural engineer
- Experience with residential homes and metal roofs
- Ability to review and interpret basic architectural sketches

Please provide a detailed report and recommendations.
