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."

"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."

Since our inception, East Coast Roofing Systems has strived to give the homeowner a breath of fresh air in the construction space. Providing seamless communication, service, and an overall experience that trumps all others. Roofing as an industry has become antiquated due to lack of technology, customer service, and quality. Because of this, the overall homeowner perception of most roofing contractors is negative. Our mission at East Coast Roofing Systems is to provide a 21st Century approach, with the ultimate goal of providing an exceptional roof inspection, installation and replacement experience. Other services offered are gutter, skylight, siding and window installation.

"Attentive and answered all my questions. Tremendous help."

FAQs for roof sealant application projects in Olney, 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.
