Structural Engineering questions, answered by experts

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

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

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

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.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
