Replacement
Commercial Roof Replacement and Reroofing
A commercial reroof takes place above an operating building. Phasing, access, weather, and daily tie-ins must be planned with the roof system.
The first decision is whether the existing roof can support a recover or must be removed. Existing layers, moisture, deck condition, and code requirements all affect that choice.
The project plan then accounts for building access, protected areas, staging, and the daily weather cutoff.
What a replacement project covers
- Assessment of the existing roof, deck, and insulation before scoping
- Tear-off or recover recommendation with the reasoning behind it
- Insulation, drainage, and detail improvements built into the new roof
- Rooftop equipment coordination, curb modifications, and rebuilt penetrations
- Edge metal, coping, and perimeter securement
- Phasing so the building keeps operating and stays dry between phases
- Daily tie-in and weather protection through the whole project
- Closeout documentation and warranty registration
Process
How a replacement runs
Assess and scope
Core cuts or a moisture survey where warranted, deck condition, existing layers, drainage, and code requirements. That produces a scope you can compare across bidders.
Plan the site
Crane or hoist locations, material staging, dumpster placement, protected parking, tenant notice, and the interior areas that need covering.
Phase the roof
The roof is divided into daily areas that close watertight. Production, occupied suites, and school calendars set the sequence.
Close out
Closeout includes a final roof walk, punch list, photos, warranty records, and the required maintenance schedule.
Replacement is usually the answer when
- Wet insulation covers a significant share of the roof
- Seams and field membrane are failing in more than isolated spots
- The roof has reached the end of its service life and repairs keep stacking up
- The deck shows corrosion, deflection, or fastener pull-out
- Existing layers or code requirements rule out another recover
Replacement plan and closeout
- A scope written so you can compare bids on the same basis
- A phasing plan tied to your operating schedule
- Daily progress photos through the project
- Closeout package with warranty registration and maintenance requirements

Common questions
Questions about this service
Can the building stay open during a reroof?
Almost always. We divide the roof into sections so occupied areas stay dry and accessible. Some buildings require night or weekend roofing, which becomes part of the schedule.
Tear-off or recover?
It comes down to the condition of the existing roof, how many layers are already on it, the deck, and the code. We will tell you which one your building supports and why.
How long does a commercial reroof take?
Roof size, access, weather, and phasing all move the number. You get a schedule with the proposal, not after the contract is signed.
