2.5 Jane and robert E. Frederick, MD

Initially Mr. Wiesman seemed alright. He explained the process for replacing our 100 year old roof. Appreciated the fact he came the same day to give an estimate in view of the heavy damage in Frederick. Installed roof May 22 . He came 5 days later. Red flag - he didn't offer a written warranty, Said to come to him if there were any problems. Didn't notice until 3 weeks later 3 problem areas- piece of trim of the front of the roof not securely nailed on. Material l buckling in several places on the side and rear. Everything visible fro the street. After 3 voice mails and 1 email he has not. Had our lawyer send him a letter which he received last week. Ding subsequent research I discovered he had 2 complaints from the Better Business Bureau- only 1 resolved. The same issue no response after problems with work. Please stay away from this company. Now I question what he might have neglected on the main roof.

0.50 Watt J. Takoma Park, MD

I had a 1 year warranty to repair the roof at our church. Three months later, the roof is leaking. I called several times for day and weeks. Finally someone answered and they will call me back. Since then I left several messages for a month. No response. I do not recommend this company. After the work is complete ,you will not hear from them any more.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.
To find more licensing information for your state, visit our Licensing Requirements page.

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.
