Wyoming Porch Roof Engineering

Job ID: 39547673

Budget: $30 – $70 USD

I need a licensed PE or Structural Engineer in Wyoming for my residential project. You will provide stamped framing and foundation plans for a porch roof I'm adding to my house.

The house is built with structural insulated panels framing (SIPs), and I’m unsure whether a ledger can safely be attached in a way that carries load.

There are two potential design routes I'm hoping to get your help evaluating:

Option A: If structurally feasible, I’d like to understand if we can safely attach a ledger board to the SIP wall and have the roof bear on the house. This would simplify the framing quite a bit.

Option B: If that’s not an option, then I’ll need the roof to be fully supported by four footings/posts. My concern is how close to the existing foundation the footings can be placed and whether there are limitations that might complicate that layout.

I’d be submitting this as a homeowner, so I'm not working with a contractor —just trying to get everything lined up to do it right.

Extra Details:

-The house is built with SIP (structurally insulated panel) framing.
-Located in Jackson, WY
-Posts would be 8x8 Douglas Fir, with 4x8 beams — going for a bulky timber-framed look.
-Roughly 16' Wide x 6' Deep x 10' Tall
-Roof pitch is roughly 2:12.
-I plan to use a metal roof, flashed to the existing house and cedar lap siding.
-Roof will cover part of the existing deck (only 12in off the ground), but the new roof structure will probably be independent from the deck framing, unless you think otherwise
-I have the project 3d modelled in Sketchup, so once we decide on the structural requirements (Ledger vs Footers) I can give you ideal design measurements so you don't have to design the whole thing from scratch

Ideal Skills & Experience:
- Licensed in Wyoming
- Experience with residential framing and foundation plans
- Structural integrity assessment for attached vs. freestanding designs

Please ensure compliance with local building codes. Looking forward to your bids!
