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."

Augustine is a veteran and offers military and senior citizen discounts. Class-A Contractors License # 2705 124869A. Additional contact name - Erin Howard.

"Overall, the workmanship was excellent, the price reasonable, and most importantly, Augustine continued to build a huge amount of trust with the customer through an honest and transparent process from beginning to end. Scheduling the initial estimate was easy and timely, good communication continued through the contract process, but we had to wait two months for word on work scheduling. Dakota Biller was a Godsend. He expertly talked through the full scope of options, pros, and cons. He listened to our unique needs, provided helpful guidance, and did not attempt to upsell. Installation was professional and cleanup was thorough. The final product looks magnificent! Price was the most reasonable of all highly ranked companies primarily due to Augustine’s willingness to only replace rotted fascia with new wood. Their 10-year warranty provided peace of mind. This was a RARE hassle-free project, and I cannot recommend Augustine Roofing enough."

"Had a section of gutter come loose, was in danger of it pulling off completely, and taking all the soffit with it.

FAQs for roof sealant application projects in Rockville, 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.
