Family owned and operated, 40 years experiece in roofing and gutters. We only use premium quality materials, highly qualified and BBB member.

"After interviewing several roofing companies, I chose Tom Parks .the son of the founder, Daniel Parks. He had an impressive portfolio of roofing jobs he had done along with many photos. He was very knowledgeable and seemed very honest and well trained especially with natural slate roofs. He worked with his son, Tom and his foreman, Edwin… they came early each day and worked non stop replacing by hand each damaged tile as well as the rotting wood. They finished the project in about four days and took many before and after photos of the roof. My family and I were very pleased with the beautiful new roof and highly recommend Daniel Parks roofing company! Also he gave us a nice discount so the price stayed within our budget."

"Had windows and doors installed by this company. The window installation went great. The bad news is that they do not seem competent at installing door hardware. My door has not latched properly since they made some unwanted modifications to the hardware (it worked perfectly before they started modifying it).have had them out three separate times to fix the issue they caused with the door latch and lock. Every “fix” they do seems to make the problem worse. I would steer clear of this company for door installations."

FAQs for roof sealant application projects in Spencerville, 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.
