Why fire damage always means open damage
People are often surprised that the holes in a burned home mostly aren’t from the fire. Firefighters force entry through locked doors, break windows to relieve heat and smoke, and cut ventilation openings in the roof to release gases and steer the fire. It is correct, life-saving practice — and it means that even a “small” kitchen fire routinely leaves a home with a forced front door, several broken windows, and a hole in the roof deck.
From the moment the last truck pulls away, that open structure is your liability. Rain enters through the roof cut. Smoke-damaged but salvageable contents sit visible through broken windows. And an unsecured fire-damaged building is an attractive nuisance in the legal sense: if someone enters and gets hurt, the owner can be exposed.
The sequence: fire marshal → release → securing
Fire board-up has one extra gate that storm work doesn’t: scene release. Until the incident commander or fire marshal releases the property, nobody boards anything — the scene may still be under investigation for cause. For ordinary residential fires release is fast, often before the trucks leave. Once you have it, the practical order of operations is:
- Call your insurer’s claim line and tell them securing is starting — many carriers pre-authorize emergency mitigation on the spot.
- Get the structure sealed: doors sheeted or fitted with lockable temporary door systems, windows boarded, and any roof ventilation cuts patched and tarped in the same visit.
- Photograph everything before and after — or confirm the crew does. Post-fire claims involve contents inventories and cause documentation, and the record of how the site was secured protects you for months afterward.
- Keep one controlled access point. You, your adjuster, and the restoration estimator will need to enter repeatedly. Good crews install a padlockable entry rather than nailing you out of your own house.
City requirements most owners don’t know about
Many cities require fire-damaged structures to be secured promptly and can cite owners — or board the building themselves and bill for it, sometimes with a lien. Philadelphia’s L&I, Chicago’s vacant-building rules, and similar codes in most large cities all treat an unsecured fire-damaged building as a violation, not a private matter. Fast professional board-up is cheaper than the municipal version in every city we’ve reviewed.
Cost, briefly
Fire securing is quoted per opening at normal board-up rates — roughly $75–$300 per window opening, more for doors and storefronts — but fire jobs involve more openings than any other damage type, so whole-home totals typically run $500 to $3,000+, plus roof tarping if decking was cut. Full numbers, including what drives jobs to the high end, are in the board-up cost guide and the roof tarping cost guide.
Frequently Asked Questions
The fire department just left. When can board-up start?
As soon as the scene is released to you — often the same hour. Crews cannot start while the fire marshal or investigators still control the scene, but release usually happens quickly for ordinary residential fires. If a fire investigation is open, ask the officer on scene when securing can begin; they deal with board-up crews constantly.
Why does a burned house need boarding at all if it’s a total loss?
Three reasons. Your policy still requires mitigation and site security even on total losses — an unsecured structure invites injury claims and theft of salvageable contents. Cities cite owners for unsecured fire-damaged buildings. And your adjuster needs the scene preserved: contents inventory, cause documentation, and salvage all happen over the following weeks.
What does fire board-up typically cost?
Fire jobs run larger than break-in jobs because the fire department creates openings on purpose — forced doors, broken windows for ventilation, and often holes cut in the roof. Whole-home fire securing typically lands between $500 and $3,000+ depending on opening count and whether roof covering is needed, at the same per-opening rates as standard board-up ($75–$300 per window).
Does homeowners insurance pay for fire board-up?
Yes — fire is the most cleanly covered peril in homeowners insurance, and post-fire securing is standard, reimbursable mitigation. Many restoration contractors will even bill the insurer directly. Keep the invoice itemized: openings boarded, roof area tarped, and any temporary fencing listed separately.
Should the roof ventilation hole be tarped or boarded?
Usually tarped, sometimes both. Vertical openings get rigid sheet material; roof openings get decking patches and a properly anchored tarp so rain stays out without trapping moisture. If your roof was opened during firefighting, make sure the crew you hire handles both board-up and tarping in one visit — it is the most common gap in post-fire securing.
