We completed a full roof replacement in Alexandria, VA after the home sustained damage from high wind speeds, which resulted in multiple missing shingles. To ensure long-term protection, we replaced both the existing shingles and the underlying decking, eliminating any compromised plywood. The new roof system was installed using GAF Timberline HDZ shingles in the color Weathered Wood, providing both durability and enhanced curb appeal. In the end, the homeowner was extremely satisfied with the results, and their positive review speaks for the quality of our work.

Excellent experience with American Group Construction. I had several estimates to re- shingle my roof, and not one was more thorough or professional than Isai and AGC. He got up on the roof, took photos, and explained all aspects of what he found and the work he offered. I needed two new skylights, which I knew in advance, but he showed me exactly why they were necessary. Other companies used satellites to measure the work, and did not see or consider the skylights. With the end of January snow storm imminent, the work could not get done, but Isai came by the house on the Saturday, hours before the storm, to 'patch' the roof to keep the home protected until the snow melted. Once the job began, the team was on time, worked tirelessly, communicated everything and once done, returned the area 'cleaner than they found it.' I would use this company again and highly recommend their work.

Alexandria Roofing FAQs

How does Alexandria’s weather affect my roof?

Alexandria’s hot, humid summers, heavy thunderstorms, and occasional snow and ice all put extra stress on roofing materials. Over time, this can lead to shingle cracking, nail pops, and worn flashing that allow water to get into your home if they’re not addressed.

How often should I have my roof inspected in Alexandria?

Most Alexandria homeowners should schedule a professional roof inspection at least once a year, plus an additional inspection after any major wind or hail storm. Regular inspections help catch small problems early—before they turn into costly leaks or interior damage.

What kinds of roof problems do you see most in Alexandria?

Common issues include wind‑damaged or missing shingles, small leaks around chimneys and skylights, aging flat roofs on additions, and storm damage from branches falling off mature trees. We see these problems in both older Alexandria neighborhoods and newer developments.

Do you work on historic or older homes in Alexandria?

Yes. We regularly work on older homes and properties in and around Alexandria, and we understand the extra care needed for aging roofs, unique architectural details, and tighter job sites. We’ll recommend solutions that respect the style of your home while improving protection.

Can you help with storm‑related insurance claims in Alexandria?

We can document storm damage with photos, provide detailed estimates, and communicate with your insurance adjuster as needed. While we don’t control what the insurance company approves, we help you understand the scope of damage and the repair or replacement options available.

What roofing materials do you recommend for Alexandria homes?

Architectural asphalt shingles are the most popular choice for Alexandria because they offer strong durability, good wind resistance, and attractive curb appeal at a reasonable cost. For certain homes, we can also discuss options like impact‑resistant shingles, metal, or other specialty materials.

How long does a typical roof replacement take in Alexandria?

Most single‑family roof replacements in Alexandria are completed in one to two days, depending on the size and complexity of the roof and current weather conditions. If we discover underlying issues such as damaged decking, we’ll explain what we found and how it may affect the schedule.

Do you also handle gutters and other exterior work in Alexandria?

Yes. In addition to roofing, we install and repair gutters, siding, and windows for Alexandria homeowners. Many roof issues are connected to drainage and exterior conditions, so we can look at your entire exterior system and recommend the best way to protect your home.
