Mr-Glass Roofing: The Sacramento Owner’s Guide
We stock and install Mr-Glass-compatible roofing materials across Sacramento, with most replacement jobs landing between $400 and $1,800 for a targeted repair and $8,000 to $20,000 for a full replacement. If your Mr-Glass roof is leaking, lifting, or showing granule loss, we can usually get a technician out to look at it within a day or two. Most owners discover the failure the hard way: a watermark on the ceiling after the first heavy Sacramento rain, or shingles scattered across the yard after a wind event off the Delta.
Mr-Glass is not a roofing manufacturer we carry as an OEM line. What we handle is the roofing system that typically sits alongside Mr-Glass products, most often glass block windows and skylights that homeowners installed as part of a remodel. When the flashing around those glass units fails, the roof itself starts taking on water. That’s the call we get: someone with a Mr-Glass skylight or glass block feature that’s now leaking, and they need the roofing around it corrected without tearing out the glass itself. Curtis Lane started Bradford Remodeling Co Sacramento to handle exactly this kind of scope: the intersection of finish glass work and the roofing that protects it.
Straight scope, firm price, no surprises after the drywall goes up.
Key Takeaways
- Mr-Glass skylight and glass block leaks are almost always a flashing or sealant failure, not a glass failure.
- Sacramento’s summer heat cycles break down roofing sealant faster than coastal climates; we see it inside 8 to 12 years.
- Written price before work starts, every time. No numbers that move at the door.
- All completed work carries the 365-Day Done Right Promise in writing.
Which Mr-Glass Models This Applies To
Mr-Glass produces glass block windows, skylights, and related glass units commonly installed in Sacramento homes from roughly the 1980s through the early 2000s. The roofing concern isn’t the glass unit itself but the interface: the curb-mounted skylight frame, the step flashing along the glass block header, and the sealant bed where the glass meets the roof deck. If you have a curb-mounted Mr-Glass skylight, the flashing dimensions will typically run 14 to 30 inches depending on the unit, and the curb height matters more than the glass dimension when we’re replacing flashing. A curb under 4 inches tall is the number one cause of skylight leaks in Sacramento, because water backs up against the frame during heavy downpours.
Here’s the compatibility gotcha most owners don’t know: Mr-Glass glass block windows installed in exterior walls were often set with a specific mortar and sealant system, and the roofing counter-flashing above them was field-cut to match. There’s no universal replacement flashing. We measure each opening, cut step flashing to the actual dimensions, and match the sealant to what’s already there. For the skylights, you can identify the unit by the label etched in the corner of the glass or stamped on the aluminum curb. If the label is gone, we work from the rough opening dimensions and the curb profile.
On OEM versus aftermarket: for the glass unit itself, OEM Mr-Glass is the only thing we’ll put back if the glass is cracked or fogged. For the surrounding roofing materials – flashing, underlayment, sealant, shingles – we use GAF and CertainTeed products because they carry manufacturer specs and warranties that we can hand you in writing alongside our own guarantee. The aftermarket decision only applies to the roofing components, never to the glass itself.
Styles & brands we work with
Signs Your Mr-Glass Roofing Is Failing
- Brown ceiling stains below the skylight or glass block wall. This is almost always a flashing failure where the roofing meets the glass. Water travels along the roof deck and exits at the first gap it finds, which is often several feet from where it entered.
- Granules collecting in the gutters. Sacramento’s UV exposure breaks down asphalt shingles faster than shaded, cooler climates. If you’re seeing granule piles in the downspout splash blocks, the shingle surface is degrading and the roof is losing its weather layer.
- Visible sealant cracks or pulling around the skylight curb. Look for a gap where the sealant bead has separated from either the glass frame or the roofing material. A 1/8-inch gap channels water directly under the flashing.
- Daylight visible through the attic around the glass block header. If you can see light between the top of the glass block and the roof sheathing, the counter-flashing has lifted or was never properly lapped. In a Sacramento winter storm, that gap becomes an open water inlet.
- Rot or softness in the roof sheathing near the glass penetration. This is the late-stage sign. By the time the plywood or OSB is soft to the touch from inside the attic, the leak has been active for months and the repair scope expands from sealing to structural deck replacement.

AfterReplacement Cost & What’s Included
For a roofing repair tied to a Mr-Glass skylight or glass block wall in Sacramento, expect $400 to $1,800 depending on what we find once the area is opened. A simple flashing re-seal runs at the low end. A full curb rebuild with new step flashing, underlayment, and shingle replacement around the penetration lands at the high end. If the deck is rotted, that’s a separate line item we show you before we cut anything.
Here’s the pricing structure we work from:
- Flashing re-seal around skylight or glass block: $400 to $900
- Step flashing replacement with new underlayment: $600 to $1,400
- Curb rebuild with deck repair (if rot is present): $1,200 to $1,800
- Full roof replacement (if the surrounding roof has failed): $8,000 to $20,000
Every price is written before we start. The Garrison Standard runs on that principle: a written scope, a firm price, and a signed guarantee in your hand at job close. No change orders that appear after the drywall opens. If the rotted deck extends beyond what we quoted, we photograph it, we show you, and we get a written approval on the revised number before we proceed. The 365-Day Done Right Promise covers every repair we complete: if the flashing fails or the sealant opens up within one year, we come back and correct it at no charge.
DIY or Call Us?
What you can safely do on your own: clean the gutters, check for granule accumulation, and do a visual inspection of the sealant bead around your skylight or glass block from ground level or from a ladder you’re confident on. If you see a cracked sealant line, you’ve found the likely entry point, and that’s worth a call.
What you should not do: get on a Sacramento roof in July to re-seal a skylight curb yourself. Roof surfaces here hit 140 to 160 degrees in summer, sealant application fails when the substrate is that hot, and the fall risk from a pitched roof is not worth the savings. The same goes for any work involving roof deck repair. If the sheathing is soft, that’s structural work that needs a trained technician who knows how to tie new decking into the existing framing without compromising the roof plane. Call us at (279) 226-1509 and we’ll put an inspection on the books with a written quote to follow.
FAQs
In Sacramento’s climate, the flashing itself can last 20 to 30 years, but the sealant around it typically fails in 8 to 12 years because the summer heat cycles expand and contract the metal against the glass. If your home is older than a decade and you’re seeing ceiling stains, the sealant is the likely culprit, not the flashing metal. Call (279) 226-1509 and we’ll inspect it and give you a written price to re-seal or replace.
Yes, if the metal is intact and only the sealant has separated, a re-seal is a legitimate repair that costs less than a full flashing replacement. If the flashing itself is corroded, bent, or torn, patching it is a short-term fix that will fail again because Sacramento’s freeze-thaw and UV cycles will open the patch within a season or two. We’ll show you which condition you’re in and quote accordingly.
A straightforward flashing re-seal around a skylight usually takes a single day from setup to clean site. A full curb rebuild with deck repair typically runs two to three days depending on how much sheathing needs to come out. We give you the timeline in writing before we start, and the site is clean when we leave: no debris, no fasteners in the yard, and a signed guarantee in your hand.
We stock the common roofing components on the truck: GAF and CertainTeed step flashing, ice and water shield, sealant matched to the existing product, and standard shingle profiles. The Mr-Glass glass unit itself is not something we warehouse, because the dimensions and curb profiles vary too widely. If your glass is cracked or fogged, we measure and order the correct OEM Mr-Glass replacement before we set any installation date, and the order time is included in the written timeline.
No. The written price is the price. If we open the roof and find rot that wasn’t visible from the exterior, we stop, take photos, and present you with a written change order for the additional scope. You approve the number before we cut further. That’s the Garrison Code: no surprises after the drywall goes up, and no work you didn’t approve in writing. Call (279) 226-1509 to get your inspection scheduled and your written quote in hand.
