Roof System for Columbus commercial properties
A silicone roof coating system restores an aging commercial roof without tear-off. Spray-applied at 20 to 30 mils over properly prepared TPO, EPDM, metal, and modified bitumen substrates, silicone coating provides a seamless waterproofing layer that qualifies for 10-year manufacturer NDL warranties and extends roof asset life by a decade or more — at roughly 50 to 60 percent of the cost of membrane replacement.
The economics of silicone roof coating make sense for a specific category of Columbus commercial building: a roof that is 10 to 18 years into its service life, showing surface weathering, minor seam lift, and early ponding but without significant embedded moisture in the insulation. That building is not ready for replacement — the insulation and deck are still sound — but the membrane is past its prime and likely to produce leaks within the next three to five years without intervention.

System selection is checked against deck capacity, insulation needs, rooftop equipment, ponding patterns, wind exposure, repairability, and warranty requirements.
Owners receive a system-level recommendation that explains what can stay, what should be removed, where risk remains, and how the selected assembly should be maintained.
Questions
The qualifying conditions are: dry insulation (confirmed by core sample or infrared), structurally sound membrane without significant blistering or delamination, less than 25 percent of the surface area showing failed seam adhesive or open splices, and no more than two inches of ponded water over more than 25 percent of the roof area at peak accumulation. We assess these conditions during a documented roof walk and provide a written qualification determination — if the building does not qualify, we explain specifically what condition disqualifies it and what would need to be addressed to qualify.
Highly reflective silicone coatings — Solar Reflectance Index (SRI) greater than 78 for low-slope roofs — can qualify as cool roof improvements under federal energy efficiency programs. Columbus commercial buildings with dark-surface membranes that convert to white silicone coating see measurable reduction in summer cooling load. We provide SRI test data for the coating products we install so building owners can evaluate incentive eligibility with their tax advisor.
Yes. At the end of the 10-year NDL warranty term, a silicone-coated Columbus roof can be recoated with an additional 10-mil top coat application to renew the warranty term — no substrate removal, no major preparation beyond cleaning and minor repair. This recoat cycle can theoretically be repeated indefinitely as long as the underlying membrane and insulation remain sound. A Columbus commercial building that installs silicone coating today and recoats every 10 years may never require a full membrane replacement, provided the substrate remains intact.
