GAF Master Elite residential roofing across Leesburg and Loudoun County. Owner-led, no sales reps.
Need to replace the roof on your Northern VA home? You need more than pretty shingles. You need a roofing system – one that will protect your home from the harshest elements for decades and decades.
And do it without breaking a sweat.
At Milcon Design & Build, we install premium GAF Lifetime Roofing Systems – and we do it to Golden Pledge standards. This means we use the highest-grade materials in GAF’s product catalog… and we install them with painstaking adherence to manufacturer standards. This lets us provide you with a Lifetime Warranty on products and installation.
Best of all? We can install your GAF roof for up to a 30% LOWER price than national companies in Northern VA! Keep scrolling to see how we provide you with the BEST possible quality… and the BEST possible value.
Our full-service roof replacement means exactly what it says – FULL service.
So while other Northern VA contractors might start their service with the first nail pulled, we start ours from the first call made. You see, exemplary customer service during the process matters just as much as the stunning roof you’ll get after the dust settles.
Let’s be real – if the replacement process for a top-of-the-line roof comes packaged with poor communication, rude customer service, and a nightmarish process, it’s partial service at best. And partial service at Milcon Design & Build is simply not tolerated.
So we’re all in from our top-of-the-line GAF residential roofing materials to our expert installation.
Once you have your first call with owner Matt Kavanah to schedule your easy breezy 30-minute quote… you’ll know we mean business.
We kick the process off as smoothly and efficiently as possible by utilizing state-of-the-art technology coupled with our equally impressive people skills.
Our seasoned roofing veteran of an owner will ask all the right questions, get to know your roof’s unique needs, and take that to his office. From there, highly-precise third-party satellite technology will measure your roof down to the inch to piece together a non-invasive accurate-to-the-inch quote.
You’ll then get the quote emailed to you so you can decide on YOUR time – without some overbearing salesman from National Roofer X breathing down your neck.
When you’ve been a contractor in Northern VA for as long as we have, you come to learn who’s who in the contractor world – both the good and the bad. This happens through word of mouth or through doing job after job with so many installers.
At Milcon Design & Build, we believe that our customers deserve nothing but the best, which is why we go above and beyond to find and then maintain solid relationships with the most qualified and reliable professionals to work on your roof.

Matt Kavanah is the owner of Milcon Design & Build. He has 20+ years of experience and has a simple philosophy, only the absolute best will do. On every single job. For every single customer. Down to every single detail.
We don’t have a bloated advertising budget or an army of salespeople. We run a tight ship with no waste and no frills. We DON’T need to inflate our prices to pay our bills.
Roofing products typically move through multiple middlemen in a supply chain before you receive them. And every stop piles on more markup YOU have to pay for. We’ve drastically reduced markup by cutting out as many of these middlemen as humanly possible.
Our installers are obsessed with details and doing the job right the FIRST time. As a result, we almost NEVER have to go back and fix installation problems, keeping our “callback costs” to a bare minimum.
Above all, we simply believe in providing top-notch roof replacement for a fair price. We sleep well at night knowing YOU sleep well at night because of your Milcon experience. Apples-to-apples, we win the roofing price war. (Which means YOU win, as well.) *When compared to national, large-scale roofing corporations. Your costs may vary. Contact us for details.
We’re a superior value to large-scale national companies… but we never try to win jobs by offering low-quality materials at the lowest price. In other words, we’re not necessarily the cheapest. We simply offer the best products and the best workmanship… at the best VALUE.
As a locally owned and operated Northern VA exterior remodeler, we don’t start with ourselves. We start with our community. This “you-centric” approach means no matter what, we will always go above and beyond to find solutions to any residential roof replacement.
We get it – that might sound a little “lip servicey” and hard to believe, given the shoddy reputation of so many Northern VA roofers. But believe us when we say we’re different from the rest.
And in typical Milcon Design & Build fashion, here’s the proof.

We’re so pleased to be able to provide this review of our recent window replacements project with Milton Design and Build- all in all, truly a 5 star event. Owner, Matt Kavanah, followed up on a Thumbtack request for proposals with a home visit to see what we needed and how Milcon Design and Build could help. Matt explained the process, how long it would take to order and get ready for the installation, and most importantly, what we could expect as performance from the ProVia window and door products recommended for our home. Matt indicated that he would have Project Manager, Josh, come out and take precise measurements to make up the order, but for the proposal pricing he was able to give us a very competitive bid based on our conversation that day. We kept coming back to Matt’s straightforward conversation and the value of the windows we would be ordering. The price and quick time-to-install just sealed the deal. Matt made some key suggestions that, after our installation today, proved to be great advice. One of the reasons we chose to do a window replacement now (January) was the cold spots in both our primary bedroom and dining room - opposite ends of our house. Even upgraded HVAC hadn’t been able to overcome the heat loss. Tonight, with a new package of high-efficiency thermally broken windows and sliders installed, we’re actually turning the thermostat down because we’re warm! Thank you to Matt, Josh, Luis, Martin, and the rest of the crew for a great job, for explaining all the tips and techniques to get the most out of the new windows and front door, as well as to keep them looking beautiful for years to come! Thank you, Milcon Design and Build for working with us on this purchase… you guys are awesome!Posted on Google![]()

Outstanding! After weeks of countless window contractor interviews, we found the perfect company. Matt at Milcon, with his many years of experience, provided us with detailed product descriptions to meet our environment requirements, that included muffling the Ashburn Data Center and air traffic noise. They installed over 40 windows in two days! Most important, my wife is so happy with our choice.Posted on Google![]()

I went to Milcon for a quote and they came in under the competition. The staff was super professional and did everything I asked for. The team was quick and was done within hours. I would go back for any future projects.Posted on Google![]()

Matt was very professional, gave us very good advice for the 2 massive doors we had to replace. We were very happy with the process, the execution of the project and the products. We had a very pleasant experience with Matt and his installation crew. Thank you so much.Posted on Google![]()

Right on time. Matt and his team did what they said they were going to do when they said they were going to do it. Painless process from start to finish. I had a new roof in about 48 hours. Highly recommended.Posted on Google![]()

We were in need of a roof replacement so we threw out a few requests on Thumbtack and I’m glad we did since it brought us to Milcon Roofing. Matt reached out very quick and if I recall correctly came out the following day to discuss options. He wasn’t pushy or trying to just sell me something. It was clear he has been in the business for years and more or less just informed me of my options. He also noted his crew gets certified on the roofing systems which we really liked. So we needed up asking for a quote and it was very fair and competitive. I will say, Matt was very professional, quick to reply to texts, his quote was very fair, and his crew was on time and knocked out the job out in less than one day. Oh, also their clean up was outstanding. While I hope to never see Matt again (since the roof will last many more years than we should be here) I would 100% call him back for any future work here or at our next home. If you need a new roof, give them a call, you won’t regret it!Posted on Google![]()

We hired Milcon Roofing, Design & Build for replacing the original aluminum siding on our house. Matt took the time to explain different options and we opted for the insulated siding. Matt was very easy to work with and communicated with us through the entire process. The work crew did an great job despite some days with rough weather. We are very happy with the results, less cold drafts, a reduction in noise and a more modern looking exterior. Everything looks great! Can't recommend enough.Posted on Google![]()
