One of the quickest ways to make a buyer or Realtor nervous during an inspection is hearing the phrase, “This needs an engineer.”
But don’t panic.
Roof and floor trusses are engineered structural systems. Unlike conventional framing, they’re designed to work together as a complete assembly, with each component carrying a specific load.
Because of that, damaged or altered trusses shouldn’t simply be repaired in the field based on someone’s opinion. The repair should follow an approved design.
The good news?
Most truss repairs are much simpler than people expect. In many cases, the repair might involve reinforcing the damaged area with additional lumber and fasteners according to a written repair detail.
And obtaining that repair detail is often easier than people realize. Many times, the truss manufacturer can provide the necessary information quickly.
The word “engineered” shouldn’t automatically raise red flags. In many cases, it simply means the repair has been reviewed and documented so everyone knows exactly how it should be completed.
I’d much rather see a documented, approved truss repair than a field repair that was never evaluated.
