  • Forget High Pressure

    Forget High Pressure

    At S&K, our motto is Worry Free. Guaranteed. We want our customers to have a great experience with us from start to finish. So why begin the relationship pressuring you into buying from us? While many roofing sales people are heavily commissioned to close a sale during their first meeting with you (some even forfeiting commission if they don't close during the first meeting), ours are not. Our sales people are compensated the same no matter when your proposal is signed. This helps ensure that our staff is providing you with an educated, no hassle buying experience.

  • Fair Pricing

    Fair Pricing, Honest Assessments

    Our staff is trained to provide you with a fair and honest assessment. You might need a replacement now, or you might not. We will tell you exactly how long we think your roof will last. That may mean that we don't get a sale now, but we're counting on it meaning you'll call us in the future. Our pricing is fair also. Compare us to others and see!

  • Worry Free. Guaranteed.

    Our Motto - Worry Free. Guaranteed.

    Our approach to home improvement sales and services is simple. Provide homeowners with an easy way to get work done right. From our sales people to our front office staff to our work crews, we strive to make each and every interaction with us Worry Free. Guaranteed.
