07 — TPO Restoration

Your TPO Roof Restored.Without Tear-Off. Without Downtime.

TPO membranes are the most restorable commercial substrate in North America. Silicone overcoat seals every seam and flashing permanently — at up to 70% of replacement cost.

The Problem with Aging TPO

Most TPO roofs don’t need replacement. They need a better seam.

After 10–15 years, TPO seams separate, flashings lift, and UV exposure brittles the membrane at laps. A full tear-off at $12–18/sq ft is the easiest quote to give — but for most TPO roofs still within the restoration window, it’s the most expensive solution to a targeted problem.

—Seam and lap failures — the #1 source of TPO leaks
—Flashing separation at parapet walls and penetrations
—UV-induced brittleness after years of thermal cycling
—Wet insulation beneath seam failures accelerating deterioration

The Restoration Solution

Seamless Silicone Overcoat

Applied directly over existing TPO, creating a monolithic membrane with no seams, laps, or penetration points as leak sources.

Seam & Flashing Reinforcement

Every seam, flashing, and penetration is reinforced with fabric-embedded silicone before the full coating — addressing root causes, not symptoms.

Manufacturer-Backed Warranty

Momentive or Gaco warranty for 10, 20, or 30 years. At warranty end: recoat, not replace. The cycle never forces a capital tearoff.

Installation Process

Four steps from survey to warranty.

TPO Condition Survey

Infrared thermal scan maps every seam failure, membrane separation, and wet insulation pocket. We determine restoration candidacy before committing to any scope.

Membrane Preparation

TPO surface is pressure-washed, all seams and flashings reinforced with fabric-embedded silicone. Wet insulation areas cut out and replaced before coating.

Silicone Overcoat

Seamless silicone membrane spray-applied over the entire TPO surface at manufacturer-specified DFT. Rain-safe in 15 minutes with zero disruption to operations.

Warranty & Documentation

Manufacturer-backed warranty documentation issued and post-installation thermal scan confirms complete coverage across all critical areas.

TPO Restoration FAQ

Common questions about TPO roof restoration

Can silicone be applied directly over existing TPO?

Yes. Silicone bonds directly to clean, sound TPO without a primer in most cases. Our crew prepares the surface, reinforces seams, and applies the coating in a single mobilization.

My TPO roof has seam failures — is it still restorable?

Seam failures are one of the most common restoration scenarios. We reinforce failed seams with fabric-embedded silicone as part of surface prep, then apply the full overcoat. The restored seam is stronger than the original.

How do I know if my TPO roof qualifies for restoration?

Candidacy depends on deck structure integrity and wet insulation saturation levels. If wet insulation is below 25% of total area, most TPO roofs qualify. Our free infrared survey determines this definitively.

Will restoration affect my building operations?

No. Installation is completed from the roof surface with no interior access required. The coating is rain-safe in 15 minutes. Most commercial TPO restorations complete in 1–3 days with zero downtime.

What happens at the end of the warranty term?

The silicone system can be recoated at warranty end for another full warranty term — no tear-off required. Your TPO roof never becomes a capital replacement line item.
