In 2026, most Mercedes-Benz Glb owners can expect sunroof (moonroof) glass replacement pricing to land in a “few hundred to low thousand” range, but the exact number depends on roof design, trim, and parts availability for your specific build. If your vehicle qualifies for a straightforward glass-only panel swap, many quotes fall around $300–$1,200. Panoramic sunroof and panoramic glass roof panels commonly run higher because the glass is larger and heavier, shipping and handling costs increase, and fewer suppliers keep every panoramic configuration on the shelf. Costs rise further when the job is not truly “glass-only.” If the cassette/module (frame, tracks, and seals) is damaged, a full assembly replacement can move the estimate into the $1,000–$2,000+ tier, and some panoramic systems go higher when parts are scarce. Beyond parts, labor is the next major driver: safe removal, bonding-surface prep, correct adhesive application, precise height and alignment, and post-install leak and wind-noise checks are what prevent repeat visits. Prior issues—bent frames, worn guides, clogged drains, or earlier water intrusion—can add work beyond “replace the glass.” At Bang AutoGlass, quoting stays simple: send your VIN and a couple clear photos of the damage, and we’ll confirm whether you need glass-only or assembly-level repair. Our mobile service can come to you as soon as next day; most glass-only installs take about 30–45 minutes, and we recommend at least one hour of safe drive-away time for adhesive cure. Every job includes a lifetime workmanship warranty, so you’re protected if leaks or wind noise show up later.
