Owner David VanLaningham founded Olde World Slate Service, LLC in 2009. His goal was to offer a superior roofing service for historic properties in Baltimore by providing excellent historic-quality work as well as an enjoyable experience for the client. Wife Jessica VanLaningham joined him in 2011 as joint owner and administrator. Their professionalism and teamwork continue to make this family-owned company one of the most-often recommended in the area.


We’ve made it our business to know our craft. We know slate, tile, metal, and flat roofing inside and out. Gutter systems too. Rather than offering many home services and knowing a little about each, we’ve chosen to specialize just in historic roofing and know ALL about it. This makes us experts.

Our sales estimators care about your needs. They are not trained in high pressure sales tactics. They are knowledgeable about the materials and about many local HOA’s. Each one is educated in the many varieties of roofing systems; they have spent time with the work crews. They are carefully chosen people that we would want to have visit our own homes. This makes us trustworthy.

Our crews are master craftsmen who care about every job they do. Several of them are from the Amish community. Our guys are dependable and their work is consistently high-quality. We are proud of the reputation that our crews have for being quiet, efficient workers, and we have very little turnover. This makes us reliable.

Our office staff is communicative, both with you and in-house. You will always know what to expect; you will get a prompt response to messages. We make sure that the excellent work you were promised at the time of your estimate is exactly what you receive. If there are surprises on the job, we contact you immediately. This makes it a pleasure to work with us.


The main objective of Olde World Slate Service, LLC is to be an honest, trustworthy voice in the roofing industry, providing excellent service on every job. We accomplish this by working for a stellar reputation among all clients and associates, and by maintaining clear communication. We strive to do business with a moral conduct that is always above reproach.
