Silicone fluid-applied roofing is one of the most capital-efficient decisions available to Salt Lake City commercial building owners who have a qualifying existing membrane. We scope, prep, and apply silicone systems with 10, 15, and 20-year manufacturer warranty paths - and we are direct about when coating is not the honest answer for a Wasatch Front building.

Silicone fluid-applied roofing restores an existing qualifying membrane by encapsulating it under a seamless, UV-stable silicone layer that provides a new warranty path at roughly 50 to 60 percent of the installed cost of full replacement. The system's UV stability is particularly relevant on the Wasatch Front: Salt Lake City's 4,226-foot elevation produces UV radiation levels measurably higher than coastal or Midwest markets, and silicone's inherent UV resistance without the chalking or cracking that affects acrylic coatings under high UV exposure makes it the preferred fluid-applied system for Utah commercial buildings.

We apply silicone coating systems from manufacturers including Tremco WJ, Versico, and Polyglass. We are not a coatings-only operation pushing silicone as the answer to every aging roof - a coating project on a roof with wet insulation or a compromised membrane will fail its warranty inspection and void coverage. Our first step on any coating inquiry is an honest substrate assessment under Utah conditions: if the roof does not qualify, we say so and scope the correct path instead.

The three warranty paths - 10-year, 15-year, and 20-year - are driven by application mil thickness, number of coating passes, membrane substrate type, and the manufacturer's published system design. One Wasatch Front-specific consideration: silicone's performance in ponded-water conditions - it does not degrade in standing water the way acrylic coatings do - is meaningful on Salt Lake City commercial roofs where spring snowmelt creates sustained ponding events on low-drainage roofs before drains can process the volume.

When Silicone Coating Is the Right Scope on a Utah Building

A roof qualifies for silicone restoration when three conditions are met: the insulation is dry, confirmed by moisture core sampling; the existing membrane is structurally sound and adhered with no open seams, delaminated sections, or saturated field; and the deck is not compromised. On the Wasatch Front, the insulation-dry condition is particularly important - Utah's freeze-thaw cycling means wet insulation under a new membrane does not passively dry out over time, it cycles between wet and frozen states, accelerating deck corrosion and membrane adhesion failure while voiding the warranty.

The most common qualifying substrates on Salt Lake City commercial buildings are: existing TPO or PVC in good membrane condition that is 10 to 20 years old; modified bitumen cap sheet in sound surface condition; and spray polyurethane foam (SPF) that is approaching its recoat interval. A meaningful portion of the Silicon Slopes and South Jordan corporate campus buildings installed between 2005 and 2015 are now entering the qualification window for silicone restoration - the right substrate age, if the membrane held condition under Utah UV and freeze-thaw exposure.

LDS-portfolio buildings and institutional properties with long planning horizons find the silicone restore-and-recoat pathway particularly attractive: a qualified 20-year system, recoated at the end of the warranty term, produces a roof that has been maintained continuously on a documented warranty basis with minimal capital disruption across a 40-plus-year building ownership cycle.
