We pride ourselves on exceeding our customer’s expectations by delivering the highest quality of workmanship and customer service on every repair and every installation.

Year after year, nearly 75% of our sales volume is from repeat customers or by direct referral from satisfied clients. We experience this kind of loyalty by working with honesty and integrity in all that we do. We never oversell something you don’t need for our benefit.

Attention to Detail

From our highly detailed evaluations to our dedicated customer service team, you will always know what to expect each day as the installation of your commercial roof progresses. You can focus on your business and not worry about whether your roofing project will be done right and on time.

Whether you need service for a flat, metal or low-sloped roof, we’re prepared to evaluate, document and help you determine the best choice for your business and your unique facility. In addition to being respectful of your business operations, we will operate safely at all times and promptly adapt our standards to any additional safety protocols you may require.

Concept to Completion

We will conduct a pre-construction conference to confirm all project details, requirements for communication with your team and any safety standards unique to your company. Each day, jobsite inspections and safety checks are conducted to ensure safety requirements are being met. The result of an aggressive approach to safety avoids injuries and near misses, saves money with reduced insurance rates, and promotes confidence and efficiency in the work force. Proper behavior by our crews on your job site results in peace of mind for you.

We treat every project like it is the most important job we’ve ever done and expect to exceed your expectations with every detail, no matter how small. We believe there is a way to do a job and then there is our way - the Sentry way!
