Commercial re-roofing
Complete commercial re-roofing: moisture survey and core cuts first, then tear-off or recover, deck repair, insulation to the current energy code, new membrane or metal, and the manufacturer's NDL warranty, by the crew that walked the roof with you.
Commercial re-roofing, the way we actually do it.
Most re-roof surprises are under the membrane: wet insulation, rotted deck, a second roof under the first one nobody mentioned. We find them before the contract. Every scope starts with an infrared moisture scan and core cuts, so the proposal shows what is actually up there and prices the deck repair as a known quantity, not an allowance that grows.
Tear-off versus recover is a real decision. Code allows one recover over a dry roof; a wet or doubled roof has to come off. We show you the scan, the cores and the cost of both where both are allowed, and tell you which we would do on our own building.
The work
Tear-off to the deck, deck repair priced by the square foot, tapered insulation to the drains where the roof ponds, cover board, and the membrane you chose. Drains, scuppers and edge metal replaced, not reused. Rooftop units lifted and reset with the HVAC contractor, curbs raised where the new insulation height requires it.
Occupied buildings
We roof over operating businesses all year. Odor and noise are scheduled with the tenants, the tear-off area is never larger than what can be dried in the same day, and the roof is watertight every night before we leave. Monsoon season is planned around, not ignored.
What happens, in order.
So you know what to expect from the first call to the last walk.

Questions about commercial re-roofing.
Can we recover instead of tearing off?
If the existing roof is dry, single-layer and the deck is sound, code usually allows one recover. The moisture scan tells us. If it is wet, it has to come off, and we show you why.
How do you handle rooftop units?
Lifted and reset with your HVAC contractor or ours; curbs raised where the new insulation height requires. Coordinated so the building does not lose cooling.
What about monsoon season?
We roof through it. Tear-off sections are sized to what can be dried in the same day, and the roof is watertight every evening.
