We have some news worth sharing. Cox Bros Roofing has earned certification from Sika, one of the most respected names in commercial roofing and construction materials in the world. This adds Sika to our existing lineup of manufacturer certifications and gives our customers access to Sika-backed warranty coverage on qualifying projects.
Who Is Sika?
Sika is a global specialty chemicals company with more than a century of experience in construction and industry. Their roofing systems are used on commercial buildings across the world, and their materials are specified by architects, engineers, and building owners who need performance they can document and stand behind.
Their own tagline says it clearly: “Protecting the past. Building the present. Innovating for the future.” That is not marketing language for Sika. It reflects a company whose products are installed on hospitals, schools, warehouses, and commercial buildings that people depend on every day.
Why This Matters for Our Customers

At Cox Bros Roofing, our commitment has always been straightforward: use quality materials, install them correctly, and back the work with real warranties. Earning Sika certification is a direct extension of that commitment.
Certification requires training, demonstrated installation competency, and meeting Sika’s quality standards before they put their name behind your work. We went through that process because our customers deserve contractors who are accountable to the manufacturers whose products they install, not just to their own word.
Sika certification means that qualifying installations completed by Cox Bros Roofing are eligible for Sika-backed manufacturer warranties. That is coverage with a global company standing behind it, on top of our own workmanship guarantee.
This is one more way we are working to give Spartanburg businesses and property owners the most reliable roofing experience available in the Upstate. When you choose Cox Bros, you are not just hiring a crew. You are getting a certified installer who has earned the right to apply the materials and activate the warranties that protect your building for the long term.
If you have questions about how Sika products or warranty coverage might apply to your next commercial roofing project, reach out. We are happy to walk you through it.
