Our Recommended Roof Coating Systems

Graduate Contracting utilizes the most innovative methods to ensure precision coverage.

  • Protect Your investment
  • Stop Roof Leaks
  • SAVE MONEY, Time & Aggravation.
  • Renew your weathered and leaking roof, while meeting roof project specification requirements.
  • Rejuvenate, Rehabilitate, Restore, Re-coat: Today’s most responsible choices available.


Save Time & Money! There’s no need to tear off and replace your weathered and leaking roof. By re-covering your roof you save on labor costs and avoid landfill expenses, plus your existing roof can be re-covered without removing existing “fixed in place” electrical equipment and related components.

Add Life to Existing Roof. By renewing your roof, you’ll never need to replace the roof again. Innovative silicone technology provides a seamless weather-tight seal that protects the substrate against ultraviolet light and severe weather, eliminates common sources of leaks and withstands permanent ponding water.

Insulate while Renewing. Combine GacoRoof Foam insulation with GacoFlex S20 Silicone Roof Coating to provide high R-value and create a monolithic system that fully adheres to any shape or substrate while providing a seamless weather-tight seal.

Perfect for Nearly Every Roof. Apply over pre-existing elastomeric roof coatings, metal roofs, built-up roofing, mineral cap sheet, and weathered single ply membrane (EPDM, TPO/CPA). Re-coat existing sprayed-in-place polyurethane foam and many other aged coatings.

Warranties on Labor & Material. All GacoFlex Silicone Roof Coatings carry a 50-year Limited Material Warranty. Manufacturer offers a full-system labor and material warranty to Qualified Applicators. Manufacturer inspects every project before and after to ensure every application is completed to high standards and merits warranty.
