American Group Construction, Inc.

American Group Construction is a family-owned business serving the Northern Virginia area. We specialize in roof repairs, installations and re-roofs. Because we are not a franchise, we are able to provide the most competitive pricing in the area. With reliability and honesty being the cornerstone of our business, we always take pictures of all current (and potential) roofing problems. This measure is taken to authenticate the problem and assist in the initial consultation process. This way the customer is always 100% informed of all points of concern. To ensure the most cost-effective option, our first step is to approach each roof as if it can be repaired before ever recommending new roof alternatives. We use only the highest quality materials and premium workmanship which is why we are able to warrantee our services for 5 years. The owner, Isai Fonseca, personally oversees and scrutinizes every project. All staff is rigorously trained and pleasant to work with.

Isai was knowledgeable and professional. Our roof had a leak issue and he took pictures and explained all how the issue would be resolved in advance. He delivered as promised.

Isai was very professional, he answered all of our questions before the job started. There were no details left out. When we had a tiny problem it was addressed immediately. We know have a beautiful new GAF asphalt roof. The yard was left in excellent condition. The work was completed in 1 day as promised. We got more then expected, and are totally happy.

The only company I xould find who would do a minor roof flashing repair on a three level townhouse that did not charge a $500 minimum. Both the customer service representative and the on-site repairman were exactly on time and wonderful to work with. I highly recommend them.

Review by in Manassas, VA
These guys really know their roofing. They did a great job roofing my shed and repairing a section of my house roof. Their pricing is fair and I am confident they gave me the best value of all three contractors I interviewed.

Polite, professional, honest and quick. Saved us thousands from money hungry roofing companies trying to upsell us on an entire, new roof. Initial response, estimate and completed roof repairs in a matter of hours. Couldn't be happier and would recommend them to anyone. Wish they did more than exterior! Thank you AGC!

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
