Mr-Glass Roof Repair in Port St. Lucie: What to Know First
Mr-Glass roof repair in Port St. Lucie is work we take on regularly, and most jobs are completed in a single visit once we’ve assessed the damage and ordered the right parts. We’re an independent Mr-Glass service provider, not a manufacturer-authorized shop, which means we’re free to recommend the fix that actually serves your roof rather than the one that serves a parts catalog. If you’re calling about a Mr-Glass skylight, roof window, or glass panel that’s leaking, fogged, or cracked, call (772) 362-3326 and a live person will answer.
How Mr-Glass Products Fail - and How We Fix Them
Mr-Glass roof glazing has its own failure patterns, and after enough jobs in St. Lucie County we can usually diagnose the problem from a phone description before we ever climb the ladder. Here’s what we see most often, and what we do about it:
- Mr-Glass ProLine skylight seal delamination. The ProLine series uses a compression gasket between the glass and the frame, and after eight to ten years of Florida sun those gaskets dry out and shrink. Water doesn’t pour in, it seeps, leaving a brown stain on the ceiling that comes and goes with rain. We remove the old gasket, inspect the frame channel for corrosion, and install a fresh seal with proper bedding compound, not silicone smeared over the old one.
- Thermal stress cracks in Mr-Glass SunView roof windows. SunView units are tempered glass, and when the edge is nicked during installation or the frame shifts on the roof curb, the glass carries stress it was never meant to. A crack runs from the corner in a single clean line. We replace the panel, but we also find and fix the binding point in the frame so the new glass isn’t set up to fail the same way.
- Fogging in Mr-Glass ThermaDome units. The ThermaDome line is a double-glazed dome with an air space between the panes, and when the edge seal fails, humidity gets in and the dome fogs from the inside where you can’t wipe it. The glass is not defective. The seal is. We replace the dome assembly with either OEM or a quality matched aftermarket unit, and we’ll quote both on paper so you see the trade-off.
- Aluminum frame pitting and weeping on older Mr-Glass RoofLite installations. RoofLite frames from the late 1990s and early 2000s were built with lighter aluminum than current production, and years of Port St. Lucie salt air causes pitting along the frame edges. Water collects in the pits and bleeds under the glazing. We sand, prime, and reseal the frame, and if the pitting has gone through, we’ll tell you honestly that a new curb-mounted unit is the better money spent.
- Improper flashing from the original install. This one is not Mr-Glass’s fault, but we see it on roughly a third of the repair calls we run. Somebody set the unit and used roofing cement instead of proper step flashing, or they shingled over the flange the wrong way. We pull the flashing, inspect the roof deck for water damage, and re-flash to code so the repair holds.
Our Mr-Glass Roof Repair Process
Every Mr-Glass job we run follows the same sequence, whether it’s a skylight dome replacement or a full roof window reseal. We don’t skip steps, and we don’t leave a homeowner guessing what happened on their roof.
- 1
You call (772) 362-3326. A live person answers, day or night. We ask what you’re seeing, when it started, and we schedule a time that works for you.
- 2
We inspect on-site. Our technician walks the roof, photographs the unit, checks the flashing, the curb, and the glass condition. We measure twice, and we write down the serial number if it’s still legible so we order the right parts the first time.
- 3
We put options in writing. If repair makes sense, we quote it. If the frame is gone and replacement is the honest call, we say so, and we’ll quote OEM against a quality aftermarket line side by side so you can see the difference in dollars and warranty coverage.
- 4
We do the work. Parts ordered, work scheduled, and our crew shows up on time, in uniform, with the tools and materials already staged. Most repairs are done in one visit.
- 5
We test and clean up. We run water over the repair where it’s safe to do so, check the interior for any sign of moisture, and leave the job site cleaner than we found it. You get the Done Right Promise in writing before the truck leaves the driveway.

Honest numbers, because that’s what you’re here for. Most Mr-Glass roof repair work in Port St. Lucie falls into these ranges:

If a Mr-Glass unit is past saving, we also work on PGT, CGI, CWS, and ES Windows systems, so you’re not left waiting on a brand-specific installer when a broader fix makes more sense. We’ll be there when we say, and we’ll be here in thirty years if you need to call us back.
FAQs
On most Mr-Glass residential units, replacement of gaskets, flashing, and exterior seals does not void the original warranty, provided the repair is performed to the manufacturer’s installation standards. If your unit is still under warranty, we’ll tell you what your warranty actually covers before we sell you a repair, and we’ll document everything in writing. Call (772) 362-3326 and we’ll walk through your specific situation.
We quote both, on paper, every time. Genuine Mr-Glass parts preserve any remaining warranty and match the original specs exactly. Quality aftermarket parts, particularly domes and glass panels from reputable domestic fabricators, often cost 20 to 35 percent less and carry their own warranty. We’ll tell you the trade-off in plain terms and let you decide.
Most roof repair calls get a technician on-site within one to three business days, and if you have an active leak during storm season we’ll move you up the schedule. A leaking skylight left alone will rot the roof deck and drywall, so the sooner you call (772) 362-3326, the smaller the repair stays.
If the glass is the problem and the frame and curb are sound, repair usually makes sense. If the frame is pitted, the curb is rotted, or the unit is over 20 years old, replacement is often the cheaper long-term decision. We’ll measure, inspect, and give you the honest answer with numbers to back it up. Estimates are free.
Full skylight replacements in Port St. Lucie typically require a permit, and we handle that as part of the job at no markup beyond the city’s filing fees. Simple glass replacement and resealing generally do not. Either way, the work is done to code and inspected when required.
