Mr-Glass Roofing: The Los Angeles Owner’s Guide
If you’re searching for a Mr-Glass roofing part in Los Angeles, here’s the direct answer: Elmstead Remodeling stocks and installs Mr-Glass-compatible roofing components, with most replacements running $470 to $2,125 installed depending on what failed and how much of the surrounding flashing or underlayment has to come apart to reach it. We can usually get the part matched and the work scheduled faster than an owner can source the right component themselves, because we already know which distributors in the LA basin carry genuine Mr-Glass series stock. Most homeowners discover the part has failed the same way they’d notice any roof problem: a water spot on the ceiling drywall, a drip during the first real rain of the season, or a piece of glass that has slipped and flashed a reflection across the kitchen at noon that was never there before.
Which Mr-Glass Models This Applies To
Mr-Glass produced several lines of glazed roof panels and skylight-adjacent roofing components over the years, and the part you need depends on which series was originally installed. The most common in Los Angeles homes we see are the Mr-Glass GS series (framed, flat-profile) and the older CF series (curb-mounted, which tended to appear on mid-century and 1970s-1980s flat roof builds in neighborhoods like Mar Vista and West Adams). If you look under the interior trim ring or along the aluminum frame, you’ll usually find a small etched or stamped code starting with either “GS-” or “CF-“. That code matters more than the measurements, because the two series use different gasket profiles and different glass retention clips, and they do not interchange. We keep both series of gaskets, clips, and replacement glazing seals on the truck. Glass itself we order cut to spec from the same LA glazing suppliers we’ve used for years, because Mr-Glass original glass is no longer manufactured and claiming to stock “genuine Mr-Glass glass” would be dishonest. The hardware and weather seals can still be sourced as genuine OEM if the distributor has them; when they don’t, we use aftermarket equivalents that match the original material specs and install them the same way. For most Los Angeles homeowners, the right call is OEM seals and clips if available, aftermarket tempered or laminated glass cut to the original dimensions, and a new seal bed every time regardless.

Signs Your Mr-Glass Roofing Is Failing
- Water staining around the interior opening or on the ceiling nearby. This usually means the perimeter seal between the glass and the frame, or the frame and the curb, has dried and cracked from years of LA heat and UV. The part isn’t the glass; it’s the gasket, and it’s a small fix if caught early.
- Visible drip during rain, especially during a wind-blown storm. In Los Angeles, we don’t get rain often enough to notice this right away. When wind drives rain at an angle, a failing Mr-Glass edge seal that’s fine in dry weather will start to leak. This is the classic LA pattern: silent for years, then a February storm exposes it.
- The glass has shifted or is sitting visibly lower in the frame on one edge. This is a failed retention clip or a rotted wood curb underneath (common on older flat-roof installations). The clip replacement is simple; the rotted curb is structural and changes the job scope.
- Condensation you can’t wipe away, trapped between two panes of glass. That’s a failed insulated glazing unit. The seal between the two panes has let moisture in, and the only proper repair is replacing the entire glass unit, not resealing from the outside.
- Cracking around the frame or nails pulling out of the surrounding roof decking. On older Mr-Glass curb mounts, we see this on homes where the roof deck was never properly reinforced when the original unit went in. The part you’re replacing is still the Mr-Glass component, but the underlying deck repair is what keeps it from failing again in three years.

AfterReplacement Cost & What’s Included
For Mr-Glass roofing repairs and replacements in Los Angeles, installed pricing breaks down like this:
- Gasket/seal replacement only: $470 – $825 installed, assuming the glass is still sound and the angle to reach it doesn’t require scaffolding.
- Glass replacement (single pane, existing frame): $710 – $1,650 installed, depending on glass size, whether it’s tempered or laminated, and whether the frame needs realignment.
- Full unit replacement (glass, frame, clips, seals, curb repair if needed): $1,180 – $2,125 installed, which is the range most complete Mr-Glass failures fall into.
Every quote includes the part, the labor to remove and reinstall properly, new sealant, clean-up, and disposal of the old glass and seal materials. We give a written price before any work starts, and that price does not move once the crew arrives. If we open the curb and find dry rot that wasn’t visible from the outside, we stop, show you what we found, and give you a separate written price for that portion before touching it. The workmanship is covered by our 365-Day Done Right Promise: if it leaks or the seal fails in the first year, we come back and make it right at no charge.
DIY or Call Us?
What you can safely check yourself: look at the frame edges for cracked, brittle, or peeling sealant; look for visible gaps where the glass meets the aluminum; note whether the glass wiggles if you press very gently from the inside. Do not walk on the roof to inspect this. Los Angeles flat and low-slope roofs are often soaked with morning dew or slick from accumulated dust, and a fall from even a single-story roof is a life-altering injury. The actual replacement work involves working with tempered and sometimes laminated glass that can weigh 60+ pounds, sealants that must be applied in a specific temperature window, and correct fastening into a roof deck that you cannot see from inside. If we get this wrong, water enters your house, and by the time you see the stain the damage is already inside your ceiling. That’s the job for a trained technician. Graham Stein has spent going on two decades working on Los Angeles homes and has opened enough curb-mounted skylights to know what reads as “fine” from the ground and isn’t fine at all once the trim ring is off. If you’re unsure whether your Mr-Glass part is repairable or needs full replacement, call us at (949) 850-9896 and we’ll talk through what you’re seeing. The call is free, and we’ll tell you honestly whether it’s worth sending someone out.
FAQs
The glass itself can last 30+ years, but the perimeter seals and gaskets on a Mr-Glass unit typically last 10 to 18 years in Los Angeles before UV and dry heat cause them to crack and fail. If your home’s Mr-Glass unit is over 15 years old and still has the original seals, the seals are living on borrowed time even if they look fine. Give us a call at (949) 850-9896 for an honest assessment.
Seals, gaskets, and retention clips can be repaired or swapped in place without replacing the glass. If the glass itself is cracked, fogged between panes, or the frame is bent or rotted, the correct repair is replacement of that component. Call (949) 850-9896 and we’ll tell you which situation you’re in.
Most Mr-Glass glass or seal replacements take half a day to a full day on site, including clean-up and sealant cure time. If the underlying curb needs wood repair, expect another half day. We protect the floor under the opening with drop cloths, wear shoe covers throughout, and photograph the clean-up before the crew leaves.
We stock the common hardware: GS and CF series gaskets, retention clips, trim rings, and sealant systems, plus the fasteners and flashing materials we need. Glass is cut to your unit’s exact dimensions at a Los Angeles glazing supplier, which is faster and more accurate than trying to warehouse dozens of glass sizes. Call (949) 850-9896 with your model code and we’ll tell you what’s in stock and what has to be ordered.
