Founded in 1992 and based in Manassas, VA, we’ve installed over 16million sqft of commercial roofing and served more than 2,000 customers across the states of Virginia, Washington, D.C. and Maryland. Our team delivers high‑performance roofing on data centers, warehouses, retail shopping centers and high‑rise offices. We’re full building‑envelope specialists. In addition to tear‑offs, overlays and new‑construction roofs, we handle masonry restoration, caulking/sealant replacement, concrete repair and waterproofing. Our crews are certified to install every major system – TPO, PVC, EPDM, modified bitumen, built‑up and liquid‑applied roofs – so clients get one source for every exterior need. You can trust our experience across industries. From multi‑building projects for major telecommunications facilities to energy‑efficient single-ply installations on Class‑A office buildings, our versatility keeps general contractors, property managers and REITs coming back. We hold elite manufacturer certifications enabling us to offer long‑term no‑dollar‑limit warranties. And when emergencies strike, our on‑call teams are ready 24/7/365 to investigate, mitigate and repair any roof or façade leak; each service call includes a detailed report and one‑year workmanship warranty. As a privately held firm with a safety‑first culture and 50+employees, Simpson Unlimited stands apart through reliability, craftsmanship and attention to detail.
