Mr-Glass Roofing: The Orlando Owner’s Guide
Mr-Glass roofing panels, skylights, and polycarbonate glazing systems fail most often at the flashing, seam, and gasket points, not the glass itself. In Orlando, we stock and install Mr-Glass-compatible replacement panels, seals, flashing, and hardware, with most repairs running $400 – $1,800 installed depending on panel size, roof accessibility, and whether the substrate (the structural layer beneath the roofing material) is still sound. The typical owner discovers the failure after a hard Florida downpour, when water stains appear on the ceiling or drips show up around the panel frame, or when they notice daylight peeking through a seam that used to be tight.
We are an independent Orlando service provider and not affiliated with Mr-Glass. That matters here because it means we match parts by measurement and application, not by brand loyalty. If a quality aftermarket panel fits better and costs less, we tell you. If OEM is the only sensible call for your warranty or your HOA, we tell you that too.
Key takeaways:
- Most Mr-Glass roofing problems are seal and flashing failures, not glass failures.
- Orlando’s UV load and afternoon thunderstorms are the two forces that age polycarbonate and gasket material faster than manufacturers’ national averages.
- We carry common panel thicknesses and replacement gasket profiles on the truck, so many repairs are one-trip.
- Every repair gets a written price before work starts and the 365-Day Done Right Promise in writing.
Which Mr-Glass Models This Applies To
Mr-Glass produces polycarbonate and acrylic glazing in a few panel families, and the compatibility question is the first thing we sort out on a call. The two most common in Orlando homes are the multi-wall polycarbonate sheets used on covered patios and pool enclosures, and the single-wall panels used for skylights, carport roofs, and small greenhouse or sunroom applications. Multi-wall panels are measured by thickness (typically 6mm, 8mm, 10mm, or 16mm in the Mr-Glass line). Single-wall panels are measured by thickness and by width, generally 24-inch, 36-inch, or 48-inch sheets cut to length.
Here is the gotcha we see often in College Park and Winter Park: a homeowner replaces a panel with the correct thickness but the wrong profile. The panel fits the opening, but the connection channels and glazing bars do not seat properly because the manufacturer’s extruded profiles are built to a specific panel geometry. We measure the old panel, check the rail or bar profile the panel slides into, and confirm the ultraviolet-facing side orientation before ordering anything. On the OEM-versus-aftermarket question, we stock quality aftermarket panels that match Mr-Glass dimensions for most 6mm, 8mm, and 10mm multi-wall applications. For thick 16mm panels and custom curved glazing, OEM is usually the safer route because the thermal expansion match and load rating matter more.

Signs Your Mr-Glass Roofing Is Failing
- Water staining around the panel perimeter or inside the glazing channels. This is the most common first sign in Orlando. The cause is nearly always a compressed or UV-brittle gasket that no longer seals the panel to the aluminum or PVC glazing bar. Once water sits in the channel, the staining spreads outward and the leak looks bigger than it is.
- Condensation or fog between the walls of a multi-wall panel. Multi-wall polycarbonate is sealed at the factory with venting tape or a solid barrier strip. When that edge seal fails, damp Florida air moves into the flutes and condenses. The panel clouds over and light transmission drops noticeably.
- Hairline cracks radiating from screw points or panel corners. Polycarbonate expands more than most homeowners expect, and Orlando’s afternoon heat cycles are brutal. If a panel was installed without oversized screw holes or proper expansion gaps, thermal movement concentrates stress at fasteners and cracks begin there. This is a measurement and installation error, not a material failure.
- Yellowing, chalking, or a brittle surface on the exposed side. UV degradation happens slowly, then all at once. A panel that looks hazy and feels rough has lost its protective co-extruded UV layer. Orlando sun will do this to an unprotected panel in six to ten years, while a proper UV-rated Mr-Glass panel should last fifteen or more.
- Flashing that has lifted, pulled away, or shows sealant that crumbles when touched. The flat aluminum flashing where a panel meets the main roof is a common leak point on Orlando homes with barrel tile or shingle roofs. The sealant fails, wind-driven rain gets underneath, and the leak travels along the roof deck before it shows up inside.

AfterReplacement Cost & What’s Included
For Orlando homeowners, Mr-Glass roof and panel repair work falls into two buckets. Panel replacement on a covered patio or skylight typically runs $400 – $1,800 installed, depending on panel size, thickness, roof height, and how much of the surrounding flashing and seal work needs to be redone. A full re-glaze of a larger pool enclosure or sunroom roof can push higher, into the $8,000 – $20,000 range if the supporting framing is still sound. The variables that move the number: panel thickness and UV rating, accessibility from a ladder versus scaffolding, and whether we are replacing one panel or re-sealing an entire run of glazing bars.
Every Mr-Glass repair we quote includes the panel or seal material, the labor to remove and reinstall, new gaskets and flashing where needed, and disposal of the old material. The written price you get before we start is the number on the invoice. Period. And every repair is covered by our 365-Day Done Right Promise: if the fix fails inside the guarantee period, we come back and make it right at no charge. No service call fee, no re-inspection fee, no argument.
DIY or Call Us?
Roofing work on any slope carries a real fall risk, and Orlando’s afternoon rain makes a damp polycarbonate surface slick in a hurry. That is our honest first word on the DIY question: if the work means getting on a roof or working overhead, call a pro. The second word is a little more useful to a capable homeowner. What you can safely do from the ground: check for cracked panels, note where water stains appear inside, check that gutters and downspouts are not dumping water against the panel edge, and clean off leaf buildup that traps moisture against glazing bars. What you should not do: pull a panel out of a glazing bar, reseal flashing from a ladder against a tile roof, or try to match panel thickness by eyeballing it. We have replaced more than a few panels that a homeowner ordered online in the wrong size or profile, and the second purchase cost more than the labor would have on day one.
If the panel is intact but the seal is failing, that is often a repair, not a replacement. Call (850) 427-6454 and describe what you see. We will tell you what we think over the phone, and if a visit will settle it, the estimate is free.
FAQs
In Orlando’s UV environment, a quality UV-protected Mr-Glass multi-wall panel should last 15 to 20 years before clouding becomes significant, while single-wall panels without a co-extruded UV layer can look rough in 8 to 12 years. The gaskets and flashing around the panels typically fail first, usually within 10 to 15 years. If your panel is clear but leaking, the seal is the problem, not the panel. Call (850) 427-6454 for an exact assessment, estimates are free.
No, and we do not recommend any patching product for a cracked structural polycarbonate panel. A crack changes the load path, and Florida wind loads will find it. We also do not seal over cracks as a long-term fix, because the panel continues to expand and contract and the patch fails. Replacement of the panel is the honest repair, and it is usually less expensive than people expect. Call (850) 427-6454 for a written quote on the panel size you have.
For a single panel on a covered patio or skylight, a one-trip swap usually takes one to three hours from setup to cleanup, provided we have the correct panel size and profile on the truck or confirmed beforehand. Multi-panel re-seal work typically runs a full day. In both cases we give you a written price and a real arrival window before the work starts. Call (850) 427-6454 and we will tell you what to expect for your specific roof.
We stock common 6mm, 8mm, and 10mm multi-wall panels, replacement gasket profiles, and aluminum flashing on the truck for most Orlando-area homes. Thicker 16mm panels, custom widths, and curved glazing are special-order, usually a few days out. We are an independent provider, which means we can also source quality aftermarket equivalents when they match the spec and save you money. Call (850) 427-6454 with your panel measurements and we will check stock while you are on the line.
