Commercial · Replacement
Commercial roof replacement sequenced around your operations
Commercial roof replacement is a capital project, and it gets managed like one: condition data first, then a program that coordinates design inputs, permits, safety, tenant operations, phasing, quality control, and closeout documentation. It is for owners and facility teams planning tear-off or recover work on an occupied building, on their calendar, not the leak's.
The program
What the replacement plan coordinates
On an occupied building, the roofing is the easy half. The plan earns its keep in everything around it.
Occupancy and communication
Tenants and operations keep running. The plan covers notifications, access changes, parking, and the daily reality of work overhead, agreed before mobilization.Safety and site logistics
Roof access, fall protection, material staging, crane or hoist days, and ground-level protection are planned and written down, not improvised on day one.Phasing and weather windows
The roof comes off in sections the crew can dry-in the same day. The building is never opened up beyond what can be closed before weather.Permits and code
Replacement triggers current code, and in most jurisdictions today that includes energy code, which commonly drives insulation values above what the old roof had. That belongs in the budget from the start, not in change orders.Procurement and submittals
Materials, submittals, and lead times are managed against the schedule, so the project isn't hostage to a missing fastener pattern approval in week three.Quality control and reporting
Inspection checkpoints during the work (seams, terminations, flashing details), with progress reporting you receive rather than request.
Decision guidance
Tear-off or recover, decided by data
Installing a new roof over the old one saves real money when the assembly qualifies, and compounds a hidden problem when it doesn't. The moisture picture makes the call.
| Consideration | Recover can qualify | Tear-off is the right call |
|---|---|---|
| Moisture | Insulation verified dry, or isolated wet areas cut out and replaced first. | Wet insulation across a significant area; recovering it seals water into the building. |
| Existing layers | A single existing roof in serviceable condition, the layer limit most codes set. | Multiple existing roofs, or a first layer too deteriorated to build on. |
| The deck | Sound, verified where it can be observed. | Deck damage or corrosion that must be exposed and corrected. |
| Attachment and wind | The combined assembly can meet the wind design the building needs. | Existing attachment can't be verified or won't carry the new loads. |
| The long game | Lower cost and less disruption now, with the layer budget spent. | Higher cost now, and the next reroof starts from a clean, known baseline. |
System choice runs parallel to this decision: TPO, EPDM, modified bitumen, built-up, metal, and their variants each detail differently at edges, penetrations, and traffic areas. The system comparisons cover the tradeoffs.
The process
How the program runs
Assessment and moisture data
Condition documentation plus moisture evaluation (core cuts or survey where warranted), because tear-off versus recover is decided by data, not preference.
You receive: A condition report with the moisture picture attached.
Design and scope
System selection, insulation and drainage design, edge and penetration details, and code requirements resolved into a written scope.
You receive: A line-item scope your stakeholders can review.
The project plan
Phasing, safety, staging, schedule, and tenant communication assembled into the plan the job is actually run from.
You receive: A plan you can circulate before anyone mobilizes.
Mobilization and protection
Staging, protection, and access installed per plan. The building's operations are disturbed exactly as much as the plan said, and no more.
Installation and checkpoints
Section by section: remove or prepare, dry-in, install, and inspect against the scope at defined checkpoints rather than at the end.
You receive: Progress reports tied to the schedule.
Closeout
Final inspection against scope, site restoration, and the complete record handed over.
You receive: As-built scope, photo record, and the documentation for the installed system.
If the assessment says the roof isn’t ready for capital replacement, that’s what you’ll hear: targeted commercial repair or a maintenance program can be the better spend, and recommending them costs us the bigger invoice.
FAQ
Replacement program questions
Can tenants stay in the building during the work?
That is the default the plan is built for. Phasing keeps work zones defined, dry-in happens the same day a section opens, and noisy or odor-producing operations are scheduled around how the building runs. What tenants experience is planned and communicated, not discovered.
How disruptive is it, honestly?
There is noise: tear-off and mechanical attachment are audible below. Some systems involve adhesive or asphalt odors, which is a real factor in choosing the system and scheduling its installation. We won’t pretend a reroof is invisible; we will put every disruption in the plan where you can schedule around it.
What decides whether we can recover instead of tearing off?
Moisture, layers, deck condition, and wind attachment, in roughly that order. Dry insulation, a single existing roof, a sound deck, and verifiable attachment make recover a legitimate saving. The assessment gathers exactly that data before the question gets answered.
Why do bids on the same roof come back so different?
Because they aren’t bidding the same roof; they’re bidding different scopes. Insulation values, edge metal, flashing details, moisture allowances, and quality checkpoints are where numbers quietly diverge. A line-item scope exists so you can put bids side by side and see what each one includes.
What should closeout include?
The as-built scope with any approved changes, the photo record including details that got covered up, and the documentation that applies to the installed system. If a closeout package would not survive a staff transition or an ownership change, it isn’t finished.
