Why Board Up and Tarping Happen First, Before Anything Else

The building envelope is the first thing to protect

A house works as a sealed system. Roofing, siding, and windows keep water and outside air where they belong, outside. Once fire burns through a section of roof or shatters glass, that seal is broken. Board up and tarping exist to rebuild a temporary version of that seal, fast, so the rest of the structure isn't taking on new damage while everyone figures out repair plans. It's not a repair. It's a pause button on further loss.

What happens if it's skipped

An open roof after a fire is an invitation to a second disaster. Arizona doesn't get constant rain, but when a monsoon storm rolls through, even a few inches of standing water inside a home can soak insulation, drywall, and framing that the fire never touched. Add in dust storms, which push fine debris into every open gap, and pests, which move into an unsecured structure within days. Insurance policies also generally expect a homeowner to take reasonable steps to prevent further damage after a loss, which is another reason this step doesn't wait.

Board up: securing the openings

Boarding up means covering broken windows, damaged doors, and any exterior openings with plywood, cut to fit and fastened securely. This does two things at once: it keeps weather and animals out, and it keeps the property from looking like an open invitation for anyone passing by. In a fire-damaged home, glass is often gone entirely or too unstable to leave in place, so board up is usually one of the first physical tasks on site.

Tarping: covering roof and structural gaps

Tarping does the same job as boarding up, but for the roof. Heavy-duty tarps get stretched over burned-through sections, torn shingles, or holes left by fire crews who had to open the roof to fight the fire from above. It's usually secured with wood strips or fasteners along the edges so wind doesn't get underneath and rip it loose. On a sloped roof, the overlap and direction of the tarp matter, water needs somewhere to run off, not pool in a low spot.

Then, and only then, the real assessment begins

Once the structure is sealed against the weather, the slower work can start: figuring out what's salvageable, what needs to come out, and what the rebuild actually looks like. Trying to assess smoke damage or start cleanup in a home that's still open to the elements means redoing work later, because new water or debris keeps changing the starting point. Sealing first means everything that follows is measured against a stable baseline instead of a moving target. If you're at this stage, the fire damage restoration process and the reconstruction and rebuild process both depend on this first step being done right.
