"The company goes out of their way to ignore reviewing HOA policy. They installed doors that were not up to code based on HOA policy.

"Very satisfied with our roof and gutter replacement project. We’re repeat customers, having hired them for storm damage repair previously. Their workmanship, fair pricing, and the thoroughness of the office staff's communication (thanks Angela & Maria!) made it an easy call when the full replacement became necessary. This project was once again overseen by Charlie - a true GEM! He is hands-on, accessible, and extremely knowledgeable. He helped us pick the best products for our house & patiently advised as we dealt with some last-minute HOA and neighbor wrinkles. The work crew was fully staffed, well equipped, and did a good job ensuring that debris from the old roof was contained and cleaned up. And at the end, Charlie made sure everything was done right and inspires our confidence that he and this team care about quality and the finished product. They did everything they said they were going to do - and they made the process easy to navigate at every step. Highly recommend!"

"Spent ~$50,000 on a new roof with them. Thought everything went well. Years later discovered that they had not sealed the cricket on the chimney well enough. Discovered water coming in and eventually rotting the wallboard, studs, etc. Had to replace entire wall. Called them about the issue, they sent a rep. He said it was the chimney's fault, it was leaking. Not so, opened the wall and ceiling and had another roofer come spray water on the chimney, nothing, no leak. Then sprayed water on the cricket, water came in. Exterior Medics would not admit any fault. Had it repaired, no leak, no problem since then. Had recommended to a friend, never gain, he also had a bad experience. DO NOT USE IF YOU WANT QUALITY WORK AND A COMPANY HAT STANDS BEHIND THEIR WORK."

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.
