Mr-Glass Roofing: The Austin Owner’s Guide
If you have a Mr-Glass roof component that’s failed or is starting to show wear, here’s the straight answer: Mason Remodeling Co Austin stocks Mr-Glass-compatible roofing parts and installs them throughout the Austin metro, with most replacements running $400 – $1,800 fully installed depending on the part and roof access. We carry OEM Mr-Glass parts plus quality aftermarket equivalents on our trucks, so most jobs get done in a single visit. The way most Austin homeowners find us: a leak shows up after a hailstorm, a skylight seal starts weeping during a heavy spring rain, or a roof penetration (vent collar, pipe boot, curb flashing) finally gives out.
One thing to know up front: Mason Remodeling Co Austin is an independent service provider. We’re not affiliated with Mr-Glass, but we’ve worked on enough of their roof systems to know exactly which parts interchange, which ones don’t, and what fails first in Texas heat.
Which Mr-Glass Models This Applies To
Mr-Glass makes a fairly wide line of glass and glazing components that end up in Austin rooflines: fixed skylights, tubular daylighting devices, glass roof panels for sunrooms, and ventilated curb-mount units. The parts we replace most often are the flashing kits, gaskets, curb seals, and glazing gaskets, not the glass itself. If the glass is intact but water’s getting in, the failure is almost always in the seal or flashing system, and that’s a lot cheaper to fix than a full unit replacement.
The key compatibility gotcha with Mr-Glass products: their curb-mounted skylights use a specific flashing profile that doesn’t interchange with Velux or other common brands. If someone slaps a generic curb flashing on a Mr-Glass unit, the corners will leak within a year or two, especially with Austin’s hard afternoon downpours. We match parts by the model number stamped on the inside of the frame, usually starting with “MG-” followed by four digits. You’ll also find the size etched on a corner of the glass panel itself.
The OEM versus aftermarket decision matters here. For interior glazing gaskets and edge seals, Mr-Glass OEM parts are worth the extra cost because the channel dimensions are tight. For roof flashings and curb sleeves, we’ve had excellent results with heavy-gauge aftermarket aluminum and EPDM replacements that actually hold up better to Texas UV exposure than some original factory parts. We’ll give you the honest recommendation on the phone, not just push the expensive option.
Styles & brands we work with
Signs Your Mr-Glass Roofing Is Failing
- Water staining on the ceiling drywall below the unit. This is the classic first sign. In Austin, it often shows up 24-48 hours after a heavy rain because the water pools on the roof and works through a failing corner gasket before the roof drains. By the time you see the stain, the seal has been compromised for weeks.
- Condensation forming between the glass panes. If your Mr-Glass unit is a double-pane or insulated glass unit and fog forms inside it, that means the edge seal has failed and the desiccant is saturated. It’ll never clear on its own. The good news: the curb and flashing are usually fine, so it’s a glass replacement, not a whole roof rework.
- Visible cracks or gaps in the rubber glazing gasket around the glass edge. Texas sun is brutal on rubber. After eight to ten Austin summers, EPDM and butyl gaskets get brittle, shrink, and pull away from the frame. You can see the gap from a ladder or, in some cases, from inside with the light at the right angle.
- Dripping or streaking down the inside of the glass, especially at the top corners. That’s a flashing failure, not a glass problem. The water is working between the curb and the roof membrane, then running down the inside face of the curb. It’s the most common misdiagnosis we see with Mr-Glass units.
- Musty smell or mold staining on the drywall within two feet of the unit opening. By this stage there’s been regular water ingress for a while. We see it most often in older Mueller neighborhood homes where the original roof install is now fifteen-plus years old and the curb flashing was never re-sealed.

AfterReplacement Cost & What’s Included
In Austin, Mr-Glass roofing repairs and part replacements run $400 – $1,800 fully installed, depending on what failed and how steep the roof access is. Here’s how it breaks down:

- Tubular daylighting dome and seal replacement: $400 – $900
- Full curb re-flashing with new sleeve and storm collar: $600 – $1,400
Every quote is a written, line-item price before any work starts. No verbal estimates that grow. You’ll know the part cost, the labor cost, and what we’re doing about roof access and cleanup. We pull permits when required by the City of Austin and handle inspections so you don’t sit on hold with the development services department. Our workmanship warranty covers the installation for 365 days from the completion date. If something fails in that window, we return and fix it at no charge.
DIY or Call Us?
There’s one safe DIY check: from inside the house, look at the interior frame where it meets the drywall. If you see cracking paint, a water line, or daylight at the corners, that tells us where the failure is and it costs you nothing but five minutes. Don’t re-caulk from the inside. It doesn’t stop the water; it just moves it somewhere else and makes the eventual repair messier.
Anything that requires getting on the roof is our department. Austin roofs get steep, especially on two-story homes in Mueller and Allandale, and the areas around roof penetrations are exactly where crews get hurt. Working around a failed Mr-Glass unit means dealing with aged sealant, sharp metal flashing, and wet surfaces. We have the safety gear, the right sealants for our climate, and the experience to know when a curb needs to be rebuilt rather than resealed. Tell me what’s wrong with it. We’ll figure out what it actually needs. Call (903) 623-1966 and we’ll get an inspection scheduled, usually within a couple of days.
FAQs
Most Mr-Glass gaskets and flashing systems last six to ten years in the Austin climate before the combination of UV exposure, heat cycling, and hail takes a toll. Insulated glass units can last twenty years or more if the edge seal was done right, but a bad one can fog in five. Realistically, plan on inspecting the seals every two years after the five-year mark and budget for replacement flashing around year eight.
Some can, and we’ll tell you honestly where. A minor flashing gap can sometimes be fixed with a proper EPDM seam and sealant job. But a saturated glazing gasket or a fogged insulated glass panel cannot be restored. Once that edge seal fails, the only real fix is new glass. Call (903) 623-1966 and we’ll walk through what we’re seeing on the phone before anyone gets on a ladder.
Most Mr-Glass part swaps are done in a half day or less, from curb flashing to glazing gaskets. An insulated glass unit replacement might take four to six hours if the frame needs cleaning and re-sealing. Roof access and weather are the usual variables, not the work itself.
We stock the most common Mr-Glass gaskets, curb flashing kits, and sealants on our trucks right here in Austin. If your unit needs a custom-sized insulated glass panel or an unusual flashing profile, we order it from our supplier network and usually receive it within three to five business days. We’ll let you know which bucket you’re in before we schedule the job, and we also stock compatible parts for KraftMaid, Cambria, and Silestone projects since we work across those lines.
