We’re a family owned and operated company that values honesty and integrity, and stands behind our work. We offer over 40 years of industry experience. We specialize in Asphalt Shingle Roofing installation, replacement, and repairs. Our services are customized to the individual project, paying close attention to the details of each project that we're involved with. We look forward to building long-term relationships with our clients and guarantee your satisfaction!

"I built the home Mr William Smith was contracted to replace the screening of the gazebo on my home’s deck and then power wash both the gazebo and deck. Do working with contractors is not new to me. After cleaning he was requested to apply a clear stain of my choice inside the gazebo and then a solid stain of my choice to both the deck surface and the gazebo’ outsides. I could not have been happier with a contractor ‘s service performance. Weather cooperating he masterfully completed everything in 3 days as estimated. The screening replacement was not straight forwarded. It not just that Mr Smith and his support did a great job he did not require deposit or payment on this scale of job until it was completed and performance approved by me. He is as open and honest of a contractor as I have met. His attention to detail was as if it was his own property. Also his cleanup was excellent. I thought his price was fair and have already recommended his services to neighbors."

This small, family-owned business did an incredible job sealing cracks in our foundation, painting the foundation and front porch, sealing the driveway, and installing gutter guards. They exceeded expectations in cost, time, and quality. The workmanship was outstanding, but what truly stood out was how kind, honest, and genuine the team was—just really good people. I’ll definitely be using their services again and will recommend them to all my contacts without hesitation."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

Roof sealant applications FAQs

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
