Most homeowners never think about their building envelope until something goes wrong. And by then, the mold is already there, the sheathing is already rotting, and the remediation quote is already six figures. In this episode, Ashley sits down with Erika Bonfanti, structural engineer turned building enclosure specialist and forensic consultant, for one of the most practical and eye-opening conversations this podcast has had on what actually keeps water out of your home and what happens when it does not.

Erika breaks down what an envelope consultant actually does, why they are not the same as an architect, and why bringing one in on the front end of a project is one of the most cost-effective decisions a homeowner can make. They go deep on flat roofs specifically, covering why membranes fail, what happens when you put a deck or pavers on top of one, why the seals around every penetration need to be replaced every two to three years, and what the building code actually requires for above-deck insulation in cold climates that almost nobody is following. They also walk through a real project in Santa Fe where all of these issues converged at once and what the solution actually looked like.

This episode is for anyone buying, building, or renovating a home with a flat roof, anyone who has ever had a leak they could not locate, and anyone who wants to understand what good looks like before something goes wrong.
