Quick answer: For an Albuquerque commercial roof, repair suits a few defined leaks, coating restoration suits a weathered but dry roof, and replacement suits wet insulation or a failing membrane. Published local data puts silicone coating near $5 per sq ft at the midpoint and installed TPO at $7 to $14. A moisture survey decides which path is honest.
Part 1 of 5
Start with moisture
Everything depends on whether the insulation under the membrane is dry. A moisture survey with probes and cores in ponding zones, curbs and old repairs answers that. Dry roofs can be repaired or restored; wet roofs need replacement in the wet areas at least.

When repair is enough
A handful of leaks at curbs, drains or seams on an otherwise sound roof are repair jobs. See commercial roof repair. Recurring leaks in new places are the sign the roof has moved past repair.

When restoration pays
A weathered but dry roof can be cleaned, repaired and coated, usually with silicone. It keeps the existing roof and insulation, avoids tear-off and disruption, and costs far less than replacement. See commercial coating and restoration.

When replacement is cheaper
Wet insulation over large areas, a failing membrane, or two existing layers point to replacement. Once two layers exist, both must come off, which adds $1.50 to $3.00 per sq ft in local data. New Mexico jurisdictions commonly require R-25 to R-30 insulation on a replacement, often the largest line. See commercial roof replacement.

Hold-period math
If you will hold the building for a decade or less, a restoration on a dry roof often delivers the needed protection at a fraction of replacement cost. For long holds, or roofs with structural or moisture problems, replacement is usually the better investment.
FAQ
Common questions on this topic
Moisture in the insulation, membrane condition and your hold period.
Local data puts silicone near $5 per sq ft midpoint versus $7 to $14 for TPO.
