"I've had two projects done with Home Genius, and everybody I've met has been responsive, friendly and courteous. I consider them family at this point and respect the kind hearted nature that everybody had displayed with me. From Ralph, Lori, Tim, Chris, Jesse, and Dylan, I have been pleasantly surprised by the warm personality of every one of them. The door installation led by Oscar and the siding installation led by Antony were equally impressive. They came in, got to work, and were more than willing to assist and answer all of the questions and concerns that I had during the process. My home has been completely transformed now, and they deserve all the good things they have coming their way. No complaints thus far whatsoever and I do not envision that changing any time soon."

"I would not hesitate to recommend - responsive, great communication, reasonable pricing. We had a disastrous roof flooding experience from a flat roofed dormer and needed it fixed quickly. As Roberto worked on the dormers he found significant water damage below the shingles, documenting it with photos for us. Although it cost more than the original estimate to replace the flat plywood sheaths and wood fascia, it was still reasonable and the work done was thorough and looks great. "

FAQs for roof sealant application projects in Harwood, MD

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.
