It wouldn't be too big for a residential home and replacing steel RSJ?
Customer: replied 4 months ago.
In terms of design I assume I can use a local SE to check my home and roof and buy a pre-stressed 'off the shelf' beam?

Prestressed beams are not typically 'off the shelf' unless its a lintel for a masonry opening, but they're relatively small. Much smaller than you'll need.
