    What DrivesCommercial Roof Cost

    Two roofs of the same size can have very different costs. These are the factors that move the number, so you know what to ask about.

    The Factors That Matter Most

    Roof size and access

    Larger roofs spread setup across more area, but tight access, height and staging needs add work.

    System choice

    TPO, EPDM, modified bitumen, BUR, SPF and metal differ in materials, labor and expected service life.

    Tear-off, recover or restoration coating

    Removing the old roof is the most work. Recovering or coating a sound roof is usually a smaller project.

    Insulation

    Insulation type, thickness, tapered sections and code-required R-value all affect the scope.

    Penetrations and rooftop units

    Every pipe, curb, skylight and HVAC unit needs flashing, and some units must be lifted or disconnected.

    Drainage changes

    Adding drains, crickets or tapered insulation to fix ponding water adds to the job.

    Deck condition

    Rusted, rotted or damaged deck found during tear-off has to be replaced before the new roof goes on.

    Code requirements

    Current energy and building codes can require more insulation, edge metal or attachment than the old roof had.

    Scheduling around occupancy

    Phasing work around tenants, patients, services or operations affects crew planning and sequencing.

    Repair, Restore or Replace?

    A quick guide to which path usually fits. The Free Roof Condition Report shows which one fits your roof.

    OptionUsually fits whenWatch for
    RepairDamage is isolated, the membrane and insulation are mostly dry and sound, and the roof has useful life left.Repeated repairs in the same area can signal a bigger problem.
    RestoreThe membrane is aging but structurally sound, insulation is dry, and you want to extend service life without a tear-off.Saturated insulation or deck damage rules out a coating.
    ReplaceWidespread membrane failure, wet insulation across large areas, deck problems, or the roof is past its service life.Plan it with a Roof Budget Forecast so it is not an emergency.
