Knox’s Construction is a Fully Insured and Certified Roofing Company
Our site supervisor and installers have been factory-trained on the latest installation methods and techniques. Why should this matter to you?
Because Knox’s Construction has been specially trained by the manufacturer to install each roofing product, you’re entitled to complete manufacturer warranty coverage. Our roofing certifications and insurance ensure this coverage.

On the other hand, the installation of roofing materials by a contractor who is not certified may invalidate the warranty, leaving you high and dry if a problem occurs. Knox’s Construction is fully committed to the practice of following manufacturer-recommended guidelines so that our customers may enjoy the benefits of a full manufacturer’s warranty.
