The Roof Solution That Saves Missouri Building Owners Money

Updated: Dec 17, 2020

When installed and maintained correctly, the average commercial roof can last anywhere from 10 – 25 years. However, life expectancy will vary based on the materials used and the installation process. Missouri business owners, building managers, and maintenance engineers will face the nerve-rattling decision to repair or replace their roof at some point in their facility ownership. The encouraging news is that there is a great option that makes the repair path a suitable choice. Here's a look at how Eureka Contracting & Roofing applies GacoFlex 100% Silicone Coating to renew a deteriorating roof, saving the building owner thousands of dollars in costly replacement.


A Missouri building owner contacted Eureka Contracting & Roofing because she recognized that her roof was aging. She understood that its compromised condition could make it vulnerable to expensive water leaks.


Eureka Contracting & Roofing performed a complimentary inspection and found the building owner’s roof to be a perfect candidate for the Gaco Silicone Roof Coating system. Keeping the customer's interest in mind, their roofing expert took the time to thoroughly explain how their selection would create a seamless membrane that would protect the property owner's damaged roof against permanent ponding water, ultraviolet light, and severe weather. They additionally highlighted how the silicone re-coating would increase the roof's eco-friendly integrity since there would be no tear-off, oversized equipment, ill-scented tar pots, or dumpsters.

Coating Details:

The roof was cleaned with a power broom, then blown off with a leaf blower and allowed to dry. After, Eureka Contracting & Roofing specialists tackled detail work applying GacoFlex SF4200 Seam Seal. With cracks, gaps, and blisters effectively filled in, the roof transformed into a smooth foundation. The Eureka Contracting & Roofing team lastly installed the GacoFlex Silicone Coating.
