DHI Roofing Contractor | Roofing Services in Rockville, MD 20852

Our specialty is the complex work others often avoid. With founder Eric Denchfield's 114,000+ hours of hands-on experience and our focus as a small, expert team, we excel at diagnosing difficult leaks—especially common local issues like persistent roof valley leaks—and executing precise repairs on intricate roof designs. We bring a problem-solving mindset honed over four thousand local jobs since 1985.

We provide honest assessments for Rockville homeowners. For a straightforward repair, that's what we'll recommend. A full replacement is advised when repair is no longer cost-effective or the roof's integrity is compromised. Our extensive experience with both services allows us to guide you to the right, long-term solution for your home and budget, specializing in complex replacement projects where detailed craftsmanship is critical.

Yes, we commonly treat roof algae stains in our Maryland climate. While often considered cosmetic, these dark streaks can retain moisture and potentially degrade roofing materials over time. We can safely clean and treat these stains. More importantly, during our inspection, we check for any underlying moisture or wear issues the staining may be masking, ensuring your roof's health is fully assessed.
