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."

"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."

FAQs for natural slate roofing repair projects in Rockville, MD

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
