Structural Engineering questions, answered by experts

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

Indications include cracks in walls, uneven floors, and sticking doors or windows that suggest foundation movements.

Most load-bearing walls are exterior, though they can also be interior.

A structural inspection report will include a detailed description of the structural engineer’s findings, applicable photographs, and recommendations to correct the issue. The contents of the report may depend on the scope of the inspection but might also include a time and cost estimate for recommended work to correct any structural problems found during the inspection. 

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.
