Mr-Glass Roof Replacement & Installation in Coral Gables: What to Know First
We install and replace Mr-Glass roof systems throughout Coral Gables, and most full replacements run three to five working days once materials land in our yard. You’ll get a written, line-item quote before we touch anything, and the price we quote is the price you pay. No change orders disguised as surprises. If you own a Mr-Glass roof in Coral Gables and it’s leaking, lifting, or just aging past its useful life, call (904) 478-8983 and we’ll walk you through what you’re actually looking at.
This page is for Coral Gables homeowners who already have Mr-Glass roofing or skylight systems and need straight answers about replacement and installation. Not a sales pitch for a different brand. Not a generic roof page with a logo slapped on it. Ed Winslow has been in South Florida construction since his days at Miami Dade College, and we’ve seen how Mr-Glass components behave after a decade of Coral Gables sun and salt air. Here’s what you need to know.
How Mr-Glass Products Fail - and How We Fix Them
Every roof system fails eventually. Mr-Glass has specific failure patterns we see repeatedly in Coral Gables, and knowing them ahead of time saves you money and keeps small problems from becoming structural ones. Here are the five we run into most.
- Seal degradation on Mr-Glass Series 700 skylight flashing. The rubberized gasket between the glass curb and the metal flashing dries out and cracks after seven to ten years of direct South Florida UV exposure. Water doesn’t pour in at first. It seeps, darkens the ceiling around the opening, and you don’t notice until paint bubbles. We replace the entire flashing assembly with a newer-generation EPDM gasket and mechanically re-secure the curb, which stops the seep at the source instead of caulking over it.
- Condensation between panes on Mr-Glass Series 500 insulated glass units. When the desiccant seal inside the double-glazed unit fails, moisture gets trapped between the glass and fogs it permanently. No amount of cleaning fixes it. The unit has to come out. We measure, order a replacement IGU matched to the original Mr-Glass dimensions, and re-bed the glass in fresh structural silicone. The frame usually stays in place, which keeps the job faster and less invasive than a full replacement.
- Aluminum frame corrosion at the corners of Mr-Glass Series 300 roof panels. Coral Gables sits close enough to Biscayne Bay that salt-laden air accelerates pitting on painted aluminum corners, especially where panels meet the curb. Once the paint goes, the aluminum underneath starts to oxidize. We strip the affected corners, treat the corrosion with a conversion coating, re-seal with marine-grade sealant, and re-coat to match. When the frame is too far gone, we quote the panel replacement honestly, not just a patch job.
- Improper slope on retrofitted Mr-Glass installations. We’ve taken over jobs in Coral Gables where a previous installer set Mr-Glass panels at a pitch that looks fine from the street but doesn’t shed water fast enough during a proper Miami downpour. Water ponds at the low edge, works its way under the cap, and rots the deck sheathing. We re-set the curb to the manufacturer’s minimum slope requirement, rebuild any damaged sheathing, and re-flash the entire perimeter before reinstalling the glass.
- Fastener pull-out on Mr-Glass Series 400 curb-mounted units after storms. High winds flex the roof deck and the curb, and over time the lag bolts that hold the curb to the framing loosen and back out. You might hear a subtle rattle during strong gusts or see slight movement at the base. We remove the old lags, inspect the underlying framing for cracks, epoxy-fill any stripped holes, and re-anchor with larger stainless hardware rated for the wind uplift zone Coral Gables sits in.
Our Mr-Glass Roof Replacement & Installation Process
We don’t do mystery timelines or vague “we’ll be there sometime next week” scheduling. Here’s exactly what a Mr-Glass roof job looks like when you call us.
- 1
Phone call and honest triage. You call (904) 478-8983 and talk to a live person, any hour. We ask what you’re seeing: water stains, fogged glass, rattling during wind, visible corrosion. That tells us whether we’re looking at a repair or a full replacement before we even schedule the visit.
- 2
Site inspection and measurements. We come out to your Coral Gables home, walk the roof, and inspect every Mr-Glass unit. We measure the openings, check the curb condition, test for moisture in the deck, and photograph everything. You get a written report of what we found, not a verbal summary.
- 3
Written quote with parts specified. The quote lists each Mr-Glass component by size and line, whether we’re using OEM glass or a quality aftermarket equivalent, and labor broken out separately. No allowances, no “to be determined later.” If we find hidden damage we didn’t quote for, we stop and call you before spending another dollar.
- 4
Removal and substrate repair. We pull the old units carefully, protect the interior work area, and expose the curb and deck. If there’s rot or water damage underneath, we repair it properly with new lumber and waterproofing before anything goes back on. That’s the part a lot of crews skip to save time, and it’s the part that determines whether the new installation lasts.
- 5
Installation and sealing. New Mr-Glass units go in, leveled and shimmed for correct drainage. Every seam gets sealed with commercial-grade sealant rated for South Florida’s UV index. Flashing is lapped so water always flows downhill and away from the opening.
- 6
Water test and final walkthrough. We run a controlled water test on every installation, then walk the job with you and point out what we did at every step. If anything’s not right, it gets fixed before you sign off. That’s the Done Right Promise at work: Ed Winslow’s name is on the door, and on every job we do.
What Mr-Glass Roof Replacement & Installation Costs in Coral Gables
Roof replacement pricing in Coral Gables runs higher than inland Miami because of the wind load requirements and the labor pool that actually shows up. For Mr-Glass work specifically, here’s what we’re seeing on our current Coral Gables jobs:
- Single skylight seal replacement: $350 to $650, depending on curb condition and access.
- Insulated glass unit replacement (one panel): $800 to $1,400, based on size and whether the frame is reusable.
- Full Mr-Glass Series 300 panel replacement (single unit): $1,800 to $3,200, including curb re-flashing.
- Complete Mr-Glass roof section replacement (multiple units plus deck repairs): $6,000 to $24,000, depending on square footage, structural repairs, and building access.
What moves the price: whether the existing curb and framing are sound, how much deck replacement is needed, access difficulty (second-story roofs, tight yard setbacks in Coral Gables neighborhoods like the Gables or the Biltmore area), and whether you need OEM Mr-Glass parts or can use matched aftermarket units. We’ll show you both options where available and let you decide. Call (904) 478-8983 for a free, written estimate. You’ll know exactly what you’re paying before we start.
Why Coral Gables Homeowners Call Winslow Windows & Doors for Mr-Glass Work
We’re the locally owned, owner-operated shop that’s been serving South Florida since 2011, and we don’t hide behind a brand name or a call center. Ed Winslow grew up right down the road in Coconut Grove, and his name is on our trucks and our license. That means something specific: when you call about a Mr-Glass roof that’s leaking, you’re calling the person who’s accountable for the fix, not a dispatcher reading from a script.
We’re an independent Mr-Glass service provider, which means we’ll give you the straight answer about parts and repairs without pushing you toward a brand replacement you don’t need. And if a replacement does make more sense, we work across the whole exterior-protection lineup: PGT, CGI, CWS, and ES Windows are all in our authorized portfolio. That matters when a Mr-Glass unit failure turns out to be part of a bigger roofing or fenestration problem. We can fix the whole thing, not just the piece that matches our logo.
Every technician who shows up at your Coral Gables door has passed a background check and arrives in uniform, so you know who’s on your property before the truck parks. Calls are answered live, 24 hours a day, by a real person. And we publish our address and license number. No shell companies, no subcontractor roulette. Upfront pricing, a free second opinion on any written estimate, no trip charge inside our home county, and a permanent 10% discount for seniors and veterans. The one down the road.
FAQs
In most cases, no. As an independent Mr-Glass service provider, we follow manufacturer installation specifications and use compatible sealing and flashing materials, which keeps your warranty intact. Where old units are already past the warranty window, we recommend the most cost-effective replacement path and tell you upfront whether OEM or quality aftermarket parts make more sense for your Coral Gables roof.
Most single-unit replacements are completed in one day, but we need one to two days for the site inspection and quote. If you’re in an emergency situation, you’ll get a live person when you call (904) 478-8983, not a voicemail loop. We’ll get you scheduled as quickly as our current Coral Gables workload allows.
Both. Many Mr-Glass issues in Coral Gables homes are repairable: seal failures, flashing degradation, condensation between panes, and frame corrosion can all be addressed without replacing the entire unit. We’ll tell you honestly when a repair is a waste of your money and a replacement is the better call. You’ll never get an upsell just because installation is more profitable.
No. The written quote you approve is the price you pay. If we find hidden deck rot or structural damage we couldn’t see during the initial inspection, we stop work, show you exactly what we found, and get your sign-off on any additional scope before proceeding. No surprise line items on the final invoice. That’s a promise, not a policy.
With proper installation, flashing, and sealant, a new Mr-Glass roof section should hold up for 15 to 25 years in South Florida’s climate. The biggest factors are whether the deck underneath was sound when the glass went in and whether the slope sheds water properly during heavy rains. We address both of those before the new units go in, which is why our Coral Gables installations tend to outlast ones that were done by crews that cut corners on the substrate work.
