Featured Project

American Legion HQ

In July of 2023, we had the honor of replacing the roof of American Legion's 8 story HQ in Washington, DC, just a couple blocks from The White House.

When American Legion contacted us, they had a significant leak. Their flat roof was previously patched, but clearly at the end of its lifespan.

My husband and I met with Pat Jewell and he was such a pleasure to work with. Very knowledgeable and kind. We felt comfortable with this company.
We are very pleased with the work that Capitol Improvements did and we would highly recommend and use them again in the future.

Veronica, Google Reviews
Seth and install team were organized and project went smoothly. Entire team was responsive and kept in touch throughout the process.
They replaced my roof including skylights in April 2023 and I am very satisfied. Melinda as my first contact was very professional and got me on the schedule quickly.
It was easy to work with Pat to get a quote. We did both a roof on our house and our shed, we also had new gutters put on our den. The crew was very hardworking and efficient.
