When a fire reaches a commercial roof in Ventura, the first question is not what kind of membrane to order. It is whether anyone can safely walk the roof yet. Fire crews, the building owner's insurer and often a structural engineer need to clear the building before a roofing crew goes up, and we wait for that. Once the roof is open to us, our job is narrower and more practical: find where the roof is no longer keeping water out, get it dried in, and work out what needs to be torn off and rebuilt. Scorch marks on the surface tell you where the heat was. They do not tell you whether the deck underneath is sound, whether the insulation is wet from firefighting water, or whether rooftop units still work. Those answers come from opening the roof and from the other trades doing their own checks.
The Thomas Fire reached Ventura and the surrounding communities, and owners here know that two buildings on the same block can come through very differently. We price each roof on its own findings. If you have a warehouse roof with fire damage, we start with that building, its access and its owner's contact, not a general estimate for the area.
Getting cleared to go on the roof
Before we schedule anything, we confirm who is managing the building after the fire and what the fire department, adjuster or engineer has said about access. If parts of the structure are still off limits, we work around them or wait. A photo from the street can show a burned parapet, but it cannot tell us whether the roof deck will hold a person. Once we are cleared, we walk the areas we can reach, take photos, mark the damage on a roof plan and note anything we could not get to. If you already have an adjuster's report or the fire department's notes, send them; they help us know where to look first and what has already been ruled in or out.
Our roof inspection after a fire lists what we checked, what we could not reach and why. If a section was closed off or unsafe, the report says so plainly, so nobody assumes that part of the roof is fine just because it is not mentioned.
What the roofing repair actually covers
Fire usually damages more than the field of the roof. Membrane can blister, shrink or melt. Insulation softens or soaks up hose water. Flashing at walls, curbs and parapets can pull loose, and sealants near the heat often fail. Our scope covers tearing off the damaged roofing, replacing insulation and cover board where needed, and installing new membrane and flashing that tie into what is left in good shape. What we do not cover is the structural repair of joists or deck, the electrical work, or replacing a burned rooftop unit. Those belong to the engineer, electrician and mechanical contractor, and we list them on our estimate as items someone else has to finish before we can close up those spots.
Walls and curbs are where this gets tricky. Flashing repair at a damaged wall cannot be finished if the wall itself still needs framing or sheathing replaced. We mark those spots so you can see what is waiting on another trade.
Finding out how far the damage goes
The top of the roof only tells part of the story. Water used to fight the fire runs into the insulation and can travel well past the burned area. We use core cuts and, where it makes sense, a moisture survey to find wet or damaged layers, and we record exactly where each sample was taken. A dry core in one corner does not prove the rest of the roof is dry, so areas we have not tested stay listed as unknown. If we open the roof and find more damage than expected, such as rotted deck or charred blocking, we stop, measure it, photograph it and get your approval before the extra work proceeds. The roof stays protected while that decision is made.
Replacing insulation and cover board can change the finished height of the roof at walls, drains and door thresholds. We check those heights before ordering material so the new roof does not end up too tall for the flashing, or so low that water collects at the drains.

Temporary protection and working around other trades
After a fire, the roof often needs to be dried in quickly while everyone figures out the permanent fix. We install temporary protection where the roof is open, and we tell you plainly what it is: a short-term measure, not a repair. Tear-off, debris removal and new roofing each have their own timing, and some of it depends on other trades. If the electrician has to disconnect a rooftop unit or the structural crew has to replace deck first, we schedule around them instead of opening the roof and leaving it waiting. We would rather start a week later than leave a building exposed to winter rain.
For a building near downtown Ventura, that often means working out deliveries, crane or hoist access, and tenant hours with the property manager ahead of time. Before we set the protection and permanent repair, we check the membrane, metal edges and drains for heat damage, debris and standing water.
What you get when the roof work is done
When we finish, you get a closeout package that shows the work we did: photos of the deck and insulation before they were covered, the new membrane and flashing, and a roof plan marking the repaired areas. It also lists anything that is still open, such as a curb waiting for a new rooftop unit or a wall the general contractor still has to rebuild. A finished roof does not mean the building is ready to reopen; that call belongs to the building official and the owner's other consultants. If a new leak shows up later, the record lets us compare it with exactly what we installed and where.
Fire can also cause unrelated damage. A membrane puncture from falling debris or a dropped tool during cleanup gets its own repair and its own entry in the report, so it is not lumped in with the fire scope.
We go through the closeout with you before we leave. You should be able to tell at a glance which roof areas are finished, which items are waiting on another contractor and who is handling each one.
One more thing worth checking after a fire is the spots where ash and debris collect: drains, scuppers, the base of equipment curbs and roof edges. We clean those out and separate real heat damage from soot or smoke staining that only needs cleaning. If we cannot tell whether part of the roof will still perform, we say what testing or opening is needed before putting a quantity on it. Interior and air-quality concerns go to the right specialists. The roof record shows what we examined, what we removed or repaired and what still has not been checked, which gives you and your insurer a clear basis for the rest of the rebuild.
Common Questions
What has to happen before you can inspect a fire-damaged roof?
The building needs to be cleared for access by the fire department, the owner's insurer or a structural engineer, depending on how bad the fire was. We confirm who is managing the building and which areas are safe. We do not walk a roof just because it looks fine from the ground.
Can you price the repair from what the roof looks like?
Not reliably. Surface damage shows where the heat was, but firefighting water often soaks insulation well beyond the burned area. We take core cuts and may run a moisture survey to find the real extent, then price from what we find instead of guessing.
What if another trade has to finish work before you can close the roof?
We mark those spots on the roof plan and in the estimate. If a rooftop unit has to be replaced or a wall rebuilt first, we schedule around that work and keep the roof temporarily protected, rather than open an area we cannot finish.
What does the closeout tell me when the roof is done?
It shows what we repaired, with photos and a marked roof plan, and lists anything still open with another contractor. It covers the roof only. Decisions about reopening the building or restoring other systems stay with the building official and your other consultants.
