American Group Construction

Roofing Contractors in Chantilly, VA

Chantilly takes its name from Chantilly Plantation, and the area saw Civil War fighting at the Battle of Ox Hill in 1862. Today it sits where U.S. Route 50 meets Route 28, just south of Washington Dulles International Airport. Suburban development accelerated after 1980 on former farmland south of the airport, while neighborhoods like Greenbriar are older.

That mix means Chantilly roofs range widely in age, from homes on their third roof to homes still on their first. American Group Construction is based in Nokesville, is a GAF Certified Plus roofing contractor and offers free roof inspections to homeowners in Chantilly.

ROOFING WORK ACROSS CHANTILLY AND FAIRFAX COUNTY

We only use high-quality materials with outstanding warranties.

Chantilly homeowners can count on American Group Construction for a full range of roofing services, from leak detection and shingle repairs to complete roof replacements and storm damage restoration. Every inspection is free, and every recommendation comes with photos of what we found.

Older Homes in Greenbriar and Nearby

Many homes in Greenbriar and other established Chantilly neighborhoods date to the 1960s and 1970s. Older homes often have more than one layer of shingles, sections of damaged decking or ventilation that no longer meets today’s standards. We inspect the decking during every replacement, show you any damaged sections and replace only what needs it.

Newer Subdivisions South of Dulles

Chantilly’s post-1980 subdivisions are now old enough that many original roofs are due for replacement. Most of these neighborhoods have homeowners associations with rules for exterior changes, so check your covenants before choosing a new shingle color or style. We provide product specifications and samples for your application.

Skylight, Chimney and Flashing Leaks

Leaks around skylights, chimneys and vents are some of the most common problems on older roofs. We replace worn flashing, repair or replace leaking skylights and repair chimney flashing so water stays out, often without replacing the whole roof.

Storm Damage and Insurance Claims in Chantilly

After a hail or wind storm, we provide free storm damage inspections, photograph the damage and give you the documentation your insurance claim needs. We also meet your insurance adjuster at your home so nothing is missed. If a storm leaves your roof open or leaking, call us right away so we can protect your home.

Repair When We Can, Replace When You Should

Not every roof problem calls for a new roof, and we will tell you when it does not. A few missing shingles, a leak at a chimney or skylight, or worn flashing can usually be repaired. When a roof is near the end of its life or damaged across large areas, replacement is the better value. We get on the roof, take photos and show you what we found before we recommend anything.

 Trustindex verifies that the original source of the review is Google. Isai with American Group Construction is just wonderful. I first found Isai about 9 years ago when had a leaky skylight when we first moved in to our home (we bought >100 year old house). I went through about 20 contractors before I found Isai. He was the only one to actually get on the roof to check and found it was the roof, not the skylight, causing problems. His crew replaced the lower roof with new skylights in just a day. He also has a great guarantee on his services.

When we thought we had a leak in the roof when it started pouring like a waterfall from the dining room, he came right out the next day to check it out. Turns out, the HVAC left a hole in the side of our house when HVAC guy installed a new unit upstairs (that is a whole other story). But Isai also determined that the upstairs roof had some issues that needed to replaced. Once again, his crew replaced the upper roof in a day and did a great job. He also replaced our garage roof at a later date.

We then had a leak through one of the skylights that we replaced. Isai came out the next day. He determined that the skylight was fine but found that an upstairs window was leaking in water (whoever originally fixed up this house just literally put bandaids over everything and now everything was coming off). We saved up the money to fix our whole outside of our house. We needed a general contractor to do the outside porch/deck, mudroom repair, and stone foundation. Isai did all the siding, windows, and doors. Isai has made our house look beautiful - a red farmhouse type.

Isai is great to work with, especially as a woman. I have had so many contractors treat me poorly or ignore me because of being a woman. But he treats everyone with respect. He is very detailed, reasonable, and gives many options. He was willing to work with us when we had hiccups and delays with the first general contractor (too bad Isai is not also a general contractor). He will fine tune until you get your vision. I now have my dream home. Trust Isai, Harry, and American Group Construction and you will not be disappointed.

 Trustindex verifies that the original source of the review is Google. I have dealt with several roofers over the years and this company has, by far, been the best. Everyone is courteous, and knowledgeable. They show up promptly and document their work. I can't say enough good things about this company. I would highly recommend them for your roofing and gutter needs.

 Trustindex verifies that the original source of the review is Google. I can’t recommend Isai from American Group highly enough—outstanding service, clear and detailed explanations, and very fair pricing. He’s incredibly honest and immediately pointed out that others had misdiagnosed the issue—I didn’t need to replace the entire gable after all. He saved me time, money, and a lot of unnecessary stress!

 Trustindex verifies that the original source of the review is Google. We highly recommend American Group Construction.  I found them through Angie’s list, because we needed to replace our roof. I called them on a late Saturday for a quote and they came the next day, on Sunday.  They were the only company who agreed to work on my schedule.  At the beginning, I had in my mind to do repairs only and replacing the roof in a couple of years, because my 3 previous quotes to replace the roof were too expensive for my budget.  When Isai came he took several pictures of my roof, and his quote for replacing the entire roof was very, very, very affordable.  Then, he explained to me the process and we discussed about any hidden damage that he could discover when replacing the roof, so everything was crystal clear. He found 5 damaged plywood, sent me the pictures and proceeded to replace them. After finishing the job, they gave me the certificate of completion for my insurance company, that lowered my annual insurance premium from $2800 to $928.  We are very happy with American Group Construction, a family owned company, they were very professional, reliable, and with the lifetime warranty on my roof, we couldn’t ask for more.  Call them, they will go above and beyond and you’ll end up with an extraordinary result. Thank you!

 Trustindex verifies that the original source of the review is Google. I'm very happy with the work American Group Construction did replacing an outside door, painting other outside doors, solving an issue with my gutters, and caulking my skylights.  Isai Fonseca, President of the company, was personally involved in all aspects of the work and quickly replied to texts as we tried to find a solution for a gutter issue.  American Group Construction replaced my roof several years ago, which was a positive experience and led me to request the recent work.  I've been very happy with the quality of work and the attentiveness of Isai.
