5.0 Charles H. Frederick, MD

What a fantastic team to work and to do business with. Reliable, professional and great customer service is just a few words to describe Exteriormax. From the beginning to the end of my roof & gutter installation they were on point with scheduling, professional work crew and most of all the quality of work. I am a very satisfied customer and will be sure to recommend them should I hear of anyone needing roof repairs and/or replacement.

5.0 Shane R. Baltimore, MD

I worked with Brian on getting everything set up from getting the inspection, to dealing with my insurance company, and made sure that he checked in during the installation to see how everything was going. ExteriorMax did a fantastic job installing my roof. They were respectful of my property, explained the process with delivering the materials and the clean up job was great. ExteriorMax really made sure that I felt comfortable, never felt pressured, and follow ups even days after the install showed they really cared. They have a customer for life in me.

5.0 Karen W. Boonsboro, MD

ExteriorMax was great! Brian Kelly helped me through the entire process and it went seamlessly! The new roof was installed in a day - and the crew took such great care of my yard and did an amazing job. Adam was helpful and the roof looks so beautiful. I wouldn't choose anyone else!

5.0 Aaron A. Hagerstown, MD

I was super impressed with the whole process they made it really simple from the initial inspection, to picking out the shingles and scheduling getting the roof done it was all a quick and easy process!!!

5.0 Chloe Z. Clarksburg, MD

Chidi helped me to go through all the process with my insurance company. Yes they helped me to file the claim and it covered the roof installation and dry wall repairs. Chidi is super gentle and very patient to explain every single step, came over for all inspections(roof and third floor dry wall) to make sure the inspector captured all issues, helped me to coordinate with drone inspection and followed up the installation. If you are planning to change or repair your roof, I highly recommend to work with Chidi from EXTERIORMAX.

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.
