Mr-Glass Roofing: The Los Angeles Owner’s Guide
We stock and install Mr-Glass-compatible roofing parts across Los Angeles, with most replacement jobs running $470 – $2,125 installed depending on the part and roof access. We carry the common failure points on our trucks, so in many cases we can swap the part the same day we come out. The call usually comes in the same way: a homeowner notices a stain on the ceiling after rain, or spots a lifted edge from the driveway, and the culprit turns out to be a failed Mr-Glass roof component that’s been quietly letting water in for weeks.
Sawyer Remodeling is an independent contractor, not a Mr-Glass dealer or affiliate. That means we match your existing Mr-Glass roof to the right part rather than steering you toward whatever brand pays the best margin. It also means we tell you the truth about whether a part is worth repairing or whether you’re better off replacing a section of roofing.
Which Mr-Glass Models This Applies To
Mr-Glass roofing systems run on a few different part families, and the compatibility gotcha that trips up most LA homeowners is this: the flashing and sealant systems on Mr-Glass skylight and roof-window units changed around 2016, so parts from a pre-2016 unit often will not seat properly on a newer curb and vice versa. If you can find the model tag, it’s usually stamped on the inside frame edge of the glass unit or on the curb itself when you lift the sash. If the tag is faded or gone, we measure the glass, check the hinge geometry, and match from spec sheets we keep on hand.
For most Mr-Glass roof parts, true OEM is the safest call when the part is still in production. For discontinued series, we use quality aftermarket equivalents that match the original dimensions within a couple millimeters. The honest tradeoff: OEM parts carry Mr-Glass’s specification guarantee, but aftermarket equivalents often arrive faster and cost 20 – 30% less. We show you the difference and let you decide before any work starts.
Styles & brands we work with
Signs Your Mr-Glass Roofing Is Failing
- Interior water staining around the skylight or roof window. This almost always means the seal between the glass unit and the curb has failed, or the curb flashing itself has lifted. It’s rarely the glass.
- Condensation between the glass panes. This is a failed argon seal on an insulated glass unit. It cannot be repaired, only replaced, and it will keep fogging no matter how many times you wipe it.
- Sagging or cracked sealant beads around the roof penetration. In Los Angeles, the sun breaks down sealant faster than rain leaks through it. Cracked sealant is a warning sign that the leak is coming within a season or two.
- Visible gaps or lifted flashing at the roof line. Wind-driven rain in the Santa Monica Mountains and foothill neighborhoods exploits any gap, even one that looks cosmetic. Lifted flashing is never cosmetic.
- Squeaking or binding when opening a Mr-Glass roof window. That’s the hinge or operator mechanism wearing out. Left too long, a binding operator will strip the crank and turn a small part into a bigger repair.
Replacement Cost & What’s Included
Installed Mr-Glass roofing part replacement in Los Angeles typically runs $470 – $2,125, with the big variable being roof access and whether the part is a simple gasket, a flashing kit, or a full glass unit. Here’s how it breaks down:
- Sealant and gasket replacement: $470 – $825 installed. This is the most common fix, and it solves most early-stage leaks.
- Flashing and curb repair: $710 – $1,650 installed. This is where you land when water has been getting under the roof membrane around the curb, which is common in older LA roofs.
- Full glass unit replacement: $1,100 – $2,125 installed. This covers failed insulated glass, cracked panes, and fogged units on Mr-Glass skylights and roof windows.
Every quote is written before we start, and the number on your invoice is the number you approved. Our written guarantee covers the workmanship on the install, and if the repair fails within a year, the follow-up visit is free under the 365-Day Done Right Promise. No arguing, no re-quote.

You can safely check two things yourself: look at the sealant bead around the curb for cracks or gaps, and look at the interior stain pattern for wet-to-touch spots versus old water marks. That tells you whether the leak is active or historical.
Actually replacing a Mr-Glass part means working on a roof, often on slope, with flashing, sealant, and glass involved. One slipped foot or one wrong sealant choice and you’ve turned a $500 repair into a $2,000 water damage claim. This is a case where the DIY savings don’t survive contact with gravity. Call us at (254) 272-5876 and we’ll come out, diagnose it, and hand you a written price before anything gets touched.
FAQs
A properly installed Mr-Glass glass unit in Los Angeles typically lasts 15 – 20 years, but the sealant and gaskets around it usually need attention by year 10 because our sun breaks down elastomeric seals faster than cooler climates. If yours is fogging or leaking at year 12, it’s not a defect; it’s normal wear. Call us at (254) 272-5876 and we’ll tell you if it’s a seal job or a full glass replacement.
Gaskets and sealant can be repaired, but a fogged insulated glass unit cannot; once the argon seal fails, the only fix is a new glass unit. Flashing can sometimes be reseated, but corroded or torn flashing needs replacement. We’ll show you exactly what’s repairable before you spend a dollar.
Most sealant, gasket, and flashing repairs take two to four hours once we’re on the roof. A full glass unit replacement usually runs half a day because we set the new unit, seal it, and test with water before we leave. You’ll have a written arrival time before we come out, not a four-hour window.
We stock common sealant, gasket, and flashing kits for Mr-Glass units on our trucks, which handles the majority of Los Angeles service calls same-day. Uncommon glass sizes or discontinued series parts may need a few days to source. If we have to order, you’ll know the day and time before we schedule the install.
