Mr-Glass Roofing: The Austin Owner’s Guide
If you own a Mr-Glass product and the roofing component has failed, we can source and install a replacement in Austin, typically for $400 – $1,800 depending on the extent of the damage. Most Mr-Glass roofing parts we see are repairable same-week, not same-day, because matching the right spec takes a few hours of parts verification. The way most Austin homeowners discover a problem is water where it shouldn’t be: a stain on the ceiling, a drip after a hard Hill Country downpour, or daylight visible through a gap that wasn’t there last year.
We’re an independent Austin contractor, not affiliated with Mr-Glass. What we do is match their roofing components to your exact model, price the work in writing before anything starts, and stand behind the repair for 365 days. Trevor Nash and the Penhallow Remodeling Austin crew have been handling these jobs for well over a decade, from South Congress bungalows to Steiner Ranch two-stories.
Which Mr-Glass Models This Applies To
Mr-Glass roofing components come in a few series lines, and they are not interchangeable. The most common we see in Austin houses are the Mr-Glass Skyline series and the older Mr-Glass ClearSpan models, which use different flashing kits and different glazing channel depths. Before you order anything, look for the label etched into the corner of the glass or stamped on the frame channel. If the label has faded, which happens fast in Texas sun, measure the thickness of the glass panel itself: Skyline runs 3/8-inch and ClearSpan runs 1/2-inch. That single measurement eliminates half the wrong-part orders we see.
On the OEM versus aftermarket question for Mr-Glass specifically: the OEM glass is good glass, but the gaskets and sealants Mr-Glass used on early ClearSpan units were the weak link, not the glass. We stock aftermarket EPDM gaskets and high-grade silicone sealants that outperform the original spec in Austin’s UV and heat cycle, and they cost less than OEM. If the glass itself is cracked or fogged, OEM is the better call because aftermarket glass rarely matches the tint and low-E coating exactly.

Signs Your Mr-Glass Roofing Is Failing
- Water staining at the corners of the interior frame. This is almost always the gasket drying out and shrinking. Austin’s summer heat accelerates gasket aging faster than the manufacturer’s lifespan estimate, which assumes a milder climate.
- Condensation between the glass panes. If it looks foggy inside and you can’t wipe it off, the inert gas seal has failed. The glass won’t shatter, but it loses its insulating value and eventually looks permanently dirty.
- Visible cracks at the anchor points. Expansion and contraction from Texas temperature swings, especially if the roof gets full afternoon sun, can stress the frame corners. A crack there lets water in around the fasteners, not through the glass.
- Drafts or a whistling sound in high wind. That’s a telltale for a failed flashing seal where the Mr-Glass unit meets the roof deck. The sealant pulls away from the metal over time, leaving a hairline gap you can’t see from the ground.
- Sagging in the center of the span. If the frame looks bowed when you sight down the edge, the support has shifted or the deck underneath has settled. That’s a structural issue, not just a parts swap.

AfterReplacement Cost & What’s Included
In Austin, Mr-Glass roofing replacement typically runs $400 – $1,800 installed, and here’s what moves the number. A gasket and sealant refresh with no glass replacement lands at the low end of that range. Replacing a single glass panel in a Skyline unit runs toward the middle. A full frame and glass replacement on a ClearSpan unit, especially one that requires roof deck repair, pushes the top of the range.
Every quote we give is a written price before work starts, and it includes the parts, labor, disposal of the old components, and a written 365-day guarantee. If the repair fails inside that year, we come back and fix it at no charge, no service call fee, no re-inspection fee. That’s the Kingswell standard Trevor Nash has run his Austin crews on since day one: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
DIY or Call Us?
The honest split is this: you can inspect, you shouldn’t repair. From the inside, run your hand along the frame corners after a rain and feel for dampness. That tells you whether you have a problem. From the outside, use a ladder only if you’re comfortable, and look for visible cracks or pulled-away sealant at the roof junction. Those checks are safe and useful.
What you shouldn’t do is get on a pitched Austin roof and start prying out glazing channels. Glass panels under tension plus a 6:12 roof pitch plus wet shingles is a combination that sends homeowners to the ER every year. If the panel is overhead, the risk isn’t just the glass breaking, it’s you going off the edge. Tell me what you need, I’ll tell you what it costs, and we’ll go from there. Call (325) 225-5429 and we’ll take a look.
FAQs
In Austin’s climate, Mr-Glass roofing units typically last 12 – 18 years before the gaskets and sealants fail, though the glass itself can last 25+ years if the frame stays sealed. The Texas heat and UV load cuts about 30% off the manufacturer’s expected lifespan for the flexible components.
Yes, in most cases. If the glass is intact and the frame is sound, a gasket and sealant rebuild fixes the leak for $400 – $1,000 in Austin. If the glass is cracked or fogged and the frame has stress cracks at the anchors, replacement is the honest answer. Call (325) 225-5429 for an exact quote, estimates are free.
A gasket and sealant rebuild on a Mr-Glass unit takes one day on site, including the time for the sealant to skin over. A full glass and frame replacement usually runs two days because the old frame comes out in the morning, the new one goes in behind it, and the roof junction gets a water test before we call it done.
We stock aftermarket EPDM gaskets, sealants, and flashing materials for the most common Mr-Glass models we see in Austin. OEM glass panels are ordered per job because the tint, low-E coating, and dimensions vary by series and year. We don’t charge a markup on the parts; you see the same number on our parts invoice that we paid, and labor is separate.
