First things first, you need to assess the condition of your existing roof. How old is it? Are there any signs of damage or wear?

  • Slate: Beautiful, long-lasting, and fire-resistant; but can be heavy and expensive.
  • Wood: Aesthetically pleasing and environmentally friendly; but can require more maintenance and be less fire-resistant.

3. Hire a Reputable Roofing Contractor

Lastly, it’s crucial to hire a reputable roofing contractor in Gaithersburg, MD. Ask for recommendations from friends, neighbors, or online reviews. Make sure they have the proper licenses, insurance, and experience. Don’t be afraid to ask for references and get multiple quotes before making your decision.
