Mr-Glass Roofing: The Los Angeles Owner’s Guide
We stock and install Mr-Glass-compatible roofing and skylight components across Los Angeles, with most glass panel and flashing replacements running $470 to $2,950 installed depending on the size, pitch, and whether surrounding shingles or tile need re-bedding. Most owners in neighborhoods like Silver Lake, Encino, and Sherman Oaks call us after a rainy week when they notice a water stain blooming across the ceiling or a drip that only shows up during a downpour. You’ll get a written price before we touch anything, and if the part is on our truck, we can usually have it swapped the same afternoon.
Which Mr-Glass Models This Applies To
Mr-Glass roofing products fall into three main lines we see across Los Angeles: their flat tempered glass skylights (most common in mid-century ranches throughout the Valley), the curved or domed acrylic models used on 1970s and 80s construction, and their glass-to-metal roof transitions used on patio covers and sunroom additions. The easiest way to identify your unit is to look for a stamped number along the aluminum frame or the underside of the glass edge, usually a four to six digit code. If the label is sun-baked or painted over, measure the rough opening between the framing members, not the glass itself: Mr-Glass panels are ordered by curb or deck mount dimensions, and a quarter-inch difference means the replacement won’t seat. We carry OEM Mr-Glass panels for most 2×4 and 4×4 units, and for discontinued sizes we order from two Los Angeles glass fabricators who cut to the original spec with matching edge treatment. Aftermarket flat glass with the right laminated construction works fine on decks, but for domed units we recommend staying with Mr-Glass molds: off-brand domes tend to yellow faster in Southern California UV exposure and often have a slightly different flange profile that leaks at the corner welds.

Signs Your Mr-Glass Roofing Is Failing
- Water staining around the interior frame. This usually means the sealant bead between the glass and the aluminum curb has dried and cracked. In Los Angeles, the heat cycling from hot days and cool nights will break that bond faster than rain ever will.
- Condensation trapped between the panes. If you see fogging you can’t wipe away, the edge seal on the insulated glass unit has failed. Once that happens, the panel’s insulating value is gone and replacement is the only fix.
- Hairline cracks running from the corners. Los Angeles is earthquake country, and small seismic shifts plus building settlement will crack tempered units that were installed too tight against the frame. When tempered glass does crack, it eventually spiderwebs across the entire panel.
- Curling or lifting flashing at the roof line. The flashing is the metal collar where the skylight meets your shingles or tile. When it lifts, water walks right under the roof covering and travels along the rafter before showing up somewhere far from the skylight itself.
- Acrylic dome clouding or turning chalky. The combination of hard water, smog, and relentless sun does this to Mr-Glass domes in LA faster than anywhere else. You can sometimes polish the surface, but if the clouding is through the material, the dome has structurally degraded.
Replacement Cost & What’s Included
For Los Angeles homes, Mr-Glass-compatible skylight and glass panel replacement typically runs $470 to $2,950 installed. The low end covers a flat glass panel swap on a curb-mount unit with flashing in good shape; the upper end covers full glass-plus-frame replacement on a tile roof where the tile has to be removed and re-bedded, plus new step flashing and sealant. The three things that move the price most are roof type (composition shingle is fastest, clay tile adds hours), deck versus curb mount, and whether we’re also repairing water-damaged drywall inside the opening. We quote parts and labor separately on every estimate, and the number is fixed: no change orders because we opened the roof and found something we didn’t expect. That’s rare, but if it happens you’ll know the new price before we continue, not after. Every repair is covered by our written 365-Day Done Right Promise, and if the repair fails inside a year, we come back and fix it for free.

You can safely check whether the interior drywall around the frame is soft, whether the exterior sealant is visibly cracked, and whether the dome has surface clouding versus through-panel haze. What you should not do is get on a roof with a tube of silicone and think you’ve solved it. We regularly fix Mr-Glass leaks in Los Angeles where a homeowner sealed the top edge but left the side flashing lifted, or caulked over the weep holes and trapped water inside the frame. Falls from roofs and working around glass at height isn’t worth the gamble, and the money saved rarely covers what a bad seal job costs when the next rain finds the gap. If you’re not sure which part you need, call (213) 277-6578. We’ll talk through what you’re seeing, and if a visit makes sense, the estimate is free.
FAQs

Flat tempered glass panels regularly last 25 to 35 years in the Los Angeles climate, while acrylic domes typically last 12 to 18 years before UV clouding and seal failure catch up with them. Flat glass is the longer-lived material in our market by a wide margin. Call (213) 277-6578 if you’re not sure which you have, and we’ll talk you through it.
For fogged insulated glass, no, the edge seal cannot be restored once moisture has entered the air space. For cracked tempered glass, no. For failed sealant on an otherwise sound panel, yes, we can remove the old bead, re-seat the glass, and re-flash the perimeter, which usually runs at the lower end of the repair range. Call us for an exact quote.
A flat glass panel swap on a curb-mount unit usually takes two to three hours from setup to cleanup. A full frame-and-flashing replacement on a tile roof can take most of a day. We’ll give you a defined arrival window before the job so you know when we’re showing up, not just which day.
We carry flat tempered glass panels in the most common Mr-Glass sizes, along with replacement sealant, torque screws, and flashing kits, because those cover the majority of Los Angeles calls. For domes and larger glass-to-metal transitions, we order from local fabricators, and that usually adds two to four business days. If you call (213) 277-6578 with your model number, we can tell you on the spot whether it’s a same-day fix or a factory-order job.
