5.0 Michael O'hearn Google Review

I’ve worked for a high-end design/build firm in the Washington DC area for more than 19 years and worked with more than a dozen roofing contractors. I’ve had the pleasure of working with DNB for more than 12 years. Aleksandra is always accommodating when scheduling site visits. Written estimates are always timely and thorough on the front end with options provided as requested. Scheduling is always easy and the work is always done to perfection. I would recommend them for any job, small or large, simple or complex!

The DNB team was professional and, most importantly, left the yard clean. The work was done as agreed, no surprises! I highly recommend DNB.

5.0 Zaga V Google Review

Thank you DNB! A great experience from start to finish. We recently had our shingle roof replaced and we are very pleased with the results. Appreciate the patience and information provided to help us understand all options before making decisions. Crew arrived on time and worked quickly. They did a good job of cleaning up when they were done. Would definitely recommend them.

5.0 Vuk Google Review

Great customer experience. After the work was complete we were amazed by the result. We had bad experiences in the past with other contractors, DNB managed to satisfy us. Prices are great and reasonable for todays market for the quality of work that we have received.

5.0 Tom N. Franklin, TN

DNB was the only company that would even come to look at my repair. When their representative arrived, he went up on my roof and located the problem. He also took pictures so he could clearly explain to me what had to be done. The repair was made the same day, after last weeks rain, no more leak. Great service!!!!

5.0 Darlingston J. Gaithersburg, MD

Did an excellent job, completed the work more quickly than expected, very good customer service, highly recommended

5.0 Fred B. Kensington, MD

We talked to six roofers before selecting DNB. Speaking with some companies was worse than dealing with a sleazy used car salesperson. DNB representative was polite, informed, and knowledgeable. He answered all of our questions immediately. The crews who worked on the house were friendly and efficient. They worked together as a team and it showed they were happy in their work. Our roof looks great. Would definitely recommend to anyone and everyone!

5.0 Peter B.

They were quick and did an excellent job. They answered my phone calls right away and were responsive. The manager was always out to see what was going on with the job. They checked up on us to make sure everything was OK. Everything went smoothly.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
