Your home needs a strong roof to protect your family and belongings. Whether you need a roof replacement, roof repairs, or a regular inspection, our team is ready to help with expert solutions using the best materials.
We use GAF Lifetime Roofing Systems, known for being strong and lasting a long time. Our roofs can handle tough weather and protect your home for many years. With our skilled team and top materials, you can count on us for a roof replacement that will keep your home safe and secure.
Just like with our commercial roofing projects, we use top materials and skilled workers to make sure your roof is built to last and protect your home.

We know that having a strong roof is really important for your business. Our roofing contractors have a lot of experience with commercial roofing projects, offering new roof installations and roof repairs to meet your business needs. Whether you own a small shop or a big building, we provide top-quality roofing services that give you maximum protection and help make your building more energy-efficient.

We use top products from trusted companies like GAF and GACO, which are known for their long-lasting materials and great performance, so your roof is built to last.

During the summer, Manassas gets very hot, and the strong sunlight can cause shingles to crack or curl. This makes your roof weaker over time. Using materials like metal roofs or energy-saving TPO roofing can help keep your roof cooler by reflecting the sunlight.
Manassas often has thunderstorms and heavy rain, especially in the warmer months. Too much rain can cause leaks or water damage if your roof isn’t in good shape. Getting regular roof checkups can help find any problems before they get worse.
Strong winds, especially during storms, can lift or tear off shingles, leaving your roof exposed. Using strong materials like GAF shingles or metal roofs helps protect your roof from wind damage.
In the winter, Manassas gets snow and freezing temperatures, which can lead to ice dams. Ice dams form when snow melts and refreezes, causing water to back up under your roof and cause leaks. A well-maintained roof with good insulation can help stop this from happening.
To keep your roof strong and safe, it’s important to use high-quality materials, get regular maintenance, and fix any damage quickly. Our team knows how Manassas weather affects roofs and can help you choose the best options to keep your roof in great shape.

Our Manassas roofing company is proud to serve the community with a team of highly experienced and certified roofing contractors. Whether you need a new roof, roof replacement, or roof repairs, our team works in a professional manner to deliver quality work on every project.

We use only the highest quality roofing materials to make sure your roof stands the test of time. From cedar shakes to metal roofs, we provide the best options for your home improvement project, guaranteeing energy-efficient results that lower energy bills.

As a family-owned business, we prioritize clear communication, transparency, and delivering an excellent job every time. Our roofing services come at a reasonable price, making sure you get the best roof without compromising quality. Whether you’re replacing your roof or installing new windows, we aim for complete customer satisfaction with every project.

I don’t send out professional sales reps armed with high-pressure tactics. Instead, you meet me, the owner – for a ZERO-HASSLE 30-minute quote.

As a locally-owned company deeply connected to the Manassas and other Northern Virginia and Maryland areas, we’re passionate about putting our best “friendly neighbor” foot forward.
For years, I worked my way up the ranks in a major home remodeling company. And I had it made. I was earning very good money and leading and managing teams of people.
Which, ironically, is why it became not so good for me.
I often thought, “Why do I have to wear a suit and a tie to sell a roof? No one is replacing a roof in a suit. It’s a blue-collar job!”
That and a million other reasons led me to start my own venture rooted in core values I could stand behind. Values like integrity, trustworthiness, and accountability, to name a few. Qualities that will show up on YOUR stunning (and cost-effective) exterior remodel.
So to wrap up what could be a much longer letter, I’ll say this:
It would be an honor for us to bring you a quality, locally-driven, above-and-beyond exterior remodel with heart and genuine care.
And to prove my commitment to you – here’s my PERSONAL cell number, where you can CALL ME DIRECTLY.

Posted on Google Nolian PapaTrustindex verifies that the original source of the review is Google. Excellent work, and the estimating scheduling process was very quick and hassle free. I'm really glad I went with Milcon.Posted on Google Jonelle HillearyTrustindex verifies that the original source of the review is Google. 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 Thomas VolkTrustindex verifies that the original source of the review is 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 Willmer RomeroTrustindex verifies that the original source of the review is 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 Bernadette RahmaniTrustindex verifies that the original source of the review is 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 Meghan KavanahTrustindex verifies that the original source of the review is Google. Excellent customer service. Quick install. Impeccable job. Would highly recommend!Posted on Google Josh EvansTrustindex verifies that the original source of the review is 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 Justin HoughtonTrustindex verifies that the original source of the review is 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 Jorge Manuel TrasmonteTrustindex verifies that the original source of the review is 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 Kristina MilbergTrustindex verifies that the original source of the review is Google. Matt and his team were great to work with, would recommend!
