Tear-off is the last resort, not the default. Here is how WatchGuard Roof systems map to the decks we restore.
Spec My Roof SystemA commercial roof at year eighteen is not a failed roof; it is a roof with failed details. Seams, fasteners, flashings and surface weathering account for nearly all leaks on structurally sound decks, and every one of those failure modes can be coated out of existence for a third to half the cost of tear-off, without landfilling the old assembly or closing the building below. The catch is system design: the right primer for the substrate, the right build coat for the movement, the right topcoat for the water and sun. That is the whole WatchGuard Roof playbook, and it changes by deck type as follows.
Metal moves, so the system must stretch. Fastener rows and seams get brush-grade polyurea detail work; the field gets a high-tensile basecoat, around 2,850 PSI with 400 percent elongation, that bridges panel movement without splitting. A reflective topcoat drops summer deck temperatures dramatically, which the building feels as lower cooling load and slower thermal cycling.
Rust is handled at the primer stage, not painted over: tight rust primed and locked, heavy scale mechanically addressed first.
Aged TPO, EPDM and mod-bit roofs are prime restoration stock: sound decks, tired surfaces. After cleaning and universal tie-coat priming, silicone build coats waterproof the field with the chemistry that laughs at ponding water, and reinforced details rebuild the seams and penetrations that were leaking. The finished assembly typically qualifies for a 10, 15 or 20 year renewable warranty.
Renewable is the operative word: at horizon, recoat and reset instead of tearing off.
Foam-over-deck is the performance ceiling of low-slope roofing: closed cell foam sprayed to the prepared deck adds R-value and slope-to-drain in one operation, then takes the coating system as its weather skin. WatchGuard Roof coatings and WatchGuard Foam are engineered as that assembly, one warranty, one supplier. For chronic ponding roofs where foam is not in budget, straight silicone systems are the honest answer; silicone is the one chemistry that shrugs off standing water indefinitely.
Commercial roofing contractors run these systems as their restoration division; building owners come to us direct and we connect them with trained applicators. Either way the spec conversation starts the same: deck type, square footage, leak history, photos if you have them.
Deck type, square footage, leak history. We return a written system spec with warranty path and coverage math.
