Mr-Glass Roofing: The West Covina Owner’s Guide
If you have a Mr-Glass roofing product that’s failed or is starting to, we stock the parts and do the repairs here in West Covina. Typical installed pricing for Mr-Glass roofing repair work runs $400 – $1,800 depending on the extent of the damage and whether we’re replacing a single skylight panel, flashing, or a section of glazing. Most West Covina owners first notice the problem after a heavy rain, when a drip shows up on the ceiling or drywall near a skylight starts to stain. You should know what you’re getting before we ever pick up a tool.
Key Takeaways:
- We’re an independent West Covina contractor, not a Mr-Glass dealer or affiliate
- Repair pricing ranges $400 – $1,800 installed; full glass roof replacement runs $8,000 – $20,000
- We carry common Mr-Glass-compatible glazing, gaskets, and flashing on the truck
- Every job includes a written price before work starts and a written guarantee after
Which Mr-Glass Models This Applies To
Mr-Glass has produced several lines of glass roofing and skylight systems over the years, and the parts aren’t always interchangeable between them. The most common units we work on in West Covina are the older single-glazed skylight units and the double-glazed glass roof panels used on patios, sunrooms, and enclosed porches. The aluminum frame profiles differ by era: older units use a narrower channel that takes a 3/8-inch glazing gasket, while newer panels seat a thicker 1/2-inch gasket. That matters when someone tries to force a new gasket into an old channel – it leaks within a season.
We also stock quality aftermarket equivalents for most Mr-Glass parts, and in many cases the aftermarket gasket material actually outlasts the original because it’s a modern EPDM formulation instead of the older vinyl that hardens in direct sun. West Covina summers are hard on rubber. If you’re looking at an OEM replacement versus an aftermarket equivalent, we’ll show you both and tell you honestly when the aftermarket is the better buy, which is most of the time for gaskets and flashing. The glass panels themselves are a different story: we match the original thickness and tint exactly, because a mismatched panel is visibly wrong from inside the house.
Styles & brands we work with
Signs Your Mr-Glass Roofing Is Failing
- Water staining on the ceiling or walls near the glass. This almost always means the flashing between the glass panel and the roof deck has separated, or the glazing gasket has cracked and pulled away. In West Covina, the summer heat dries out sealant faster than most manufacturers accounted for.
- Condensation between the panes. That’s a failed seal in a double-glazed unit. It cannot be wiped off; the dry air between panes has been lost and the panel needs replacement. We see this most often on west-facing elevations where afternoon sun is relentless.
- A visible crack or chip in the glass itself. Tempered glass doesn’t usually crack without a cause – a branch, a poorly seated frame, or a structural shift. A cracked panel will eventually fail completely, and it’s safer to replace it before that happens.
- Draft or heat radiating through the panel. If you can feel a temperature difference standing under the glass, the thermal seal is gone even if there’s no visible condensation. Your air conditioning is working harder than it should.
- Rust staining on the frame or fasteners. The anodized finish on older Mr-Glass frames eventually wears through, especially on homes near the hills where morning marine layer lingers. Once the aluminum starts corroding, tightening or adjusting the frame fights a losing battle.

Every repair carries a written guarantee, and the 365-Day Done Right Promise covers the work for a full year from the completion date.

DIY or Call Us?
There are things you can check safely from inside the house: look at the gasket for visible cracking, note where water stains are appearing, and mark the panel so you can tell us exactly which one is the problem. That saves time on the quote visit. What you should not do is climb onto a glass roof or work on a ladder at roofline height to remove panels yourself. Glass roofing panels are heavy, and tempered glass under tension can shatter violently if handled incorrectly from a bad angle. The professional move is a phone call, not a weekend with a putty knife.
We work throughout West Covina, including the neighborhoods around Eastland Center and the older housing stock north of the 10.

You’ll get a written price, a confirmed arrival with the technician’s name and photo before we come, and a straight answer on what needs to happen.

FAQs
A well-maintained Mr-Glass roof in our climate typically lasts 15 to 25 years before the glazing and flashing reach the end of their useful life, but the sealants and gaskets often need attention every 8 to 12 years because the Southern California sun breaks down rubber and caulk faster than the glass or aluminum degrade. Call (707) 760-7579 for an exact assessment of your roof’s condition.
Most single-panel failures, gasket deterioration, and flashing problems can be repaired without replacing the entire roof, which is why we always start with a full inspection before recommending scope. If the frame itself is corroded or multiple panels have failed seals, full replacement may be the cheaper long-term path.
Most single-panel gasket and flashing repairs are completed the same day, within 2 to 4 hours including cleanup. Multi-panel work or a full glass roof replacement is scheduled as a larger project, and we’ll give you a clear timeline with the written estimate.
Yes, our West Covina trucks carry common Mr-Glass-compatible glazing gaskets, flashing, sealants, and matching glass panels in the most common thicknesses and tints. For unusual panel sizes or older series units, we order the part and schedule the install once it arrives, usually within a week.
