New supports and existing-deck assessment
A roofed porch needs a support design for the actual roof and platform. The assessment should establish whether existing foundations, posts and framing can serve the new loads and layout. Additional supports or rebuilding may be necessary even when the walking boards are in good condition. For a new construction project, coordinate these requirements from the outset. A complete estimate identifies the structural work explicitly, so the roof is not treated as a decorative cover attached to an unspecified existing deck.
