Coatings Comparison
When the roof is structurally sound with dry insulation, restoring with Cool Roof Coat costs $2–6/sq ft versus $5.50–25 to replace; full tear-off is the honest answer once insulation is saturated past ~25% or the deck is compromised.
The restore-or-replace call is empirical, not rhetorical. A qualified assessment pulls core samples, runs infrared or capacitance moisture scans, checks seams and flashings, and maps saturation percentage. Under roughly 25% wet with a sound deck, repair the wet zones and restore the field; over it, replace. Most structurally sound roofs we assess turn out to be restoration candidates rather than tear-offs.
Restoration with Cool Roof Coat upgrades the roof's physics in a way replacement cannot. The ICP™ film reflects 97% of solar energy, re-radiates absorbed heat, and slows conduction at 0.051 W/m·K — three mechanisms no factory membrane carries — while adding a renewable, up-to-20-year NDL wear layer the existing roof never had. The savings are real: restoration runs 50–70% below replacement cost, finishes in days rather than weeks, and sends zero tons to landfill against the ~70,000–100,000 lbs a typical commercial tear-off generates.
Replacement still wins when the roof is no longer a substrate — saturated insulation past the ~25% line, structural deck compromise, or membrane failure too widespread to detail. The sections below break the decision down by use case, with honest tradeoffs where full replacement is the better pick.

| Landfill waste | None | ~70,000–100,000 lbs per typical commercial roof |
| Energy outcome | 97% reflectance + emissivity + low-conductivity film; up to 50% HVAC reduction | Depends on chosen membrane; new code-minimum insulation |
| Code treatment | Maintenance — preserves roof count | New system — consumes roof count or forces tear-off |

| When it fails you | Applied over wet/failed assemblies (disqualified by inspection) | When the existing roof had years of life you paid to discard |
Installed cost: Replacement installed-cost range per 2025 commercial roofing pricing references — standard single-ply systems land roughly $5.50–12/sq ft, with premium membranes (PVC, standing-seam metal) running higher.
This is most commercial roofs at year 12–18: tired surface, sound bones. Repair the defects, restore with a 40-mil monolithic ICP™ membrane, and bank the difference — typically 50–70% of replacement cost — plus up to 50% HVAC savings the old roof never offered.
Coating over wet insulation seals the problem in, breeds blisters and adhesion failure, and voids warranties. Past the ~25% saturation threshold, partial repairs stop penciling; replace the assembly. The honest sequel: coat the new roof at mid-life so this is the last tear-off you ever fund.
Tear-off means days of open-roof exposure, fastener noise through the deck, odors at intakes, and staging in your loading areas. Restoration is quiet maintenance: water-based, no reportable VOCs, low-odor, sections returned to service daily.
Code caps stacked roofing at two systems. At the cap, "re-roof" legally means "tear off everything first" — replacement's price jumps by the demolition line. Restoration, classified as maintenance, sidesteps the trigger entirely.
No coating fixes structure. Deck repair or replacement comes first; any restoration conversation waits for a sound substrate. We disqualify these roofs at inspection — and tell you why.
Replacement buys you a new roof that behaves thermally like the old one. Restoration with a 97%-reflectance, high-emissivity, low-conductivity surface attacks the actual operating cost — the field-measured ceiling is a 49% HVAC reduction on a 180,000 ft² retrofit.
Replacement is the right answer when the roof is no longer a substrate — saturated insulation past the ~25% line, structural deck compromise, or membrane failure too widespread to detail. At that point a coating is cosmetics over a failed assembly, and any contractor who quotes one is selling you a callback. Replacement is also the cleaner path when an owner wants one decision and one 15–30 year warranty covering an entirely new system, or when the project scope already includes major rooftop equipment replacement that would trash a fresh coating.
The costs are equally real: $5.50–12/sq ft for standard systems (to $25 for premium), in line with 2025 commercial roofing pricing references, plus weeks of disruptive construction, 35–50 tons of tear-off to landfill from a typical commercial roof, and — frequently overlooked — the discarded value of every year the existing roof had left. Industry practice converges on a simple rule: replace when the assembly is wet or structural, restore when it's sound. Most structurally sound roofs we assess turn out to be restoration candidates rather than tear-offs.
The restore-or-replace call is empirical, not rhetorical. A qualified assessment pulls core samples, runs infrared or capacitance moisture scans, checks seams and flashings, and maps saturation percentage. Under ~25% wet with a sound deck: repair the wet zones, restore the field. Over it: replace — and specify the new roof with a mid-life coating plan so the next cycle is maintenance instead of demolition.
Restoration with Cool Roof Coat then does what replacement can't: it upgrades the roof's physics. The ICP™ film reflects 97% of solar energy, re-radiates absorbed heat, and slows conduction at 0.051 W/m·K — three mechanisms no factory membrane carries — while adding a renewable, up-to-20-year NDL wear layer the existing roof never had.
