Manassas Roofing Company

Shanco started off as a humble little business in 2002, providing roofing services to both residential and commercial customers. Since then, it has gradually expanded to include Northern Virginia, Maryland and D.C. We work hard to ensure that local homeowners and business owners don’t have to worry about the roofs over their heads, come storm or tornado.

Throughout the years, our business has acquired certifications with GAF Materials Corporation as a Green Roofer and Master Elite Builder and is certified as lead-safe by the Environmental Protection Agency. Shanco is always striving to be environmentally conscious, especially now at this crucial time for our planet.

Roof Inspections

Damage to your roof may come at the most unexpected of times, but it’s not always easy to determine where the damage is located. At other times, roofs are in obvious need of replacement, and that’s why we’re here for you.

We use satellite technology to ensure your roofing estimate is 99.9% accurate. Manual inspections can be time-consuming, but automating this process saves time and gives us an accurate 3-D aerial image of your roof alongside 24-hour access to estimate-related data. 

Our roof inspections are free of charge, and a quote is then given to you based on our investigation.

It’s recommended that property owners have their roofs inspected every few years regardless of their condition, as damage can add up over time and be invisible to the naked eye.

Roof Repair

If your roof is leaking or otherwise suffering from structural damage, don’t wait any further. A leaking roof can lead to additional costs for you, such as ceiling damage, electrical issues, or even mold. A simple call to our business will ensure that a team of trained and certified roofing professionals arrives at your address in a timely manner.

At Shanco, referrals from satisfied customers are our main source of new business, so we understand the importance of doing the job right the first time. 

Roof Replacement

Roof replacement is sometimes preferable to repair, as some factors, such as excessive damage or old age, may make it impractical to repair a roof. 

In addition, replacing the roof can help reduce your home’s energy consumption, which is in line with our green-friendly policy. You may also wish to expand your house, which could require roof replacement.

We use high-standard industry materials to create our roofs, such as asphalt shingles, which are the most popular type of residential roof material, as they are affordable, durable, and recyclable. Used shingles are donated and then recycled to make hot mix asphalt for paving roads.

New Windows

Manassas summers can be humid, so mold, wood rot, and hail dents to windows can leave your house exposed to outside moisture. We’re here to help replace any damaged or deteriorating windows for you. Through our partnership with Pella, we offer efficient window solutions for any client. The InsulShield glass collection is an innovative way to help reduce energy bill costs and increase efficiency. Our windows can save you money in the long-run, and our warranty lasts for as long as you own the property.


Home siding is a great way to enhance your home’s aesthetics as well as help reduce energy consumption and deter pests and rotting.

We offer a variety of siding options for our clients, including:

  • Vinyl
  • Fiber cement
  • Cedar

Shanco has partnered with manufacturer James Hardie to offer fiber cement siding products that help give your house durable protection with colors that resist fading.
