Mr-Glass Roofing: The San Francisco Owner’s Guide

We stock Mr-Glass-compatible skylight and glass roofing components at Bradford Remodeling Co San Francisco, and we install them for a typical flat-rate of $470 – $2,125 depending on the part and the roof pitch. Most San Francisco homeowners find us after a fog-season leak or a cracked pane that finally gave way, and we can usually have the right part matched and on the truck within one business day. The telltale sign is almost always water where it shouldn’t be: a drip line on the ceiling below, discolored drywall around the glass, or a visible crack in the sealant bead that’s turned brittle from years of UV and salt air.

Which Mr-Glass Models This Applies To

Mr-Glass frames and glazing units come in a few standard curb-mount and deck-mount configurations, and the compatibility gotcha in San Francisco is almost always the curb size. Older homes in the Outer Sunset and Richmond District tend to have 14½-inch and 22½-inch curb openings, while newer construction runs 30-inch and 36-inch. If you measure the inside of the existing curb before you call, we can tell you on the phone whether we stock the right glass pack or need to order it. For most owners, OEM Mr-Glass glass is the right call when the frame is still square and sealed; we go aftermarket only when the original frame is discontinued and the opening is a standard size that accepts a code-compliant insulated unit. Bradford Remodeling Co San Francisco is an independent service provider, not a Mr-Glass dealer, which means we match the part to the opening rather than trying to sell you a full replacement you don’t need.

Signs Your Mr-Glass Roofing Is Failing

• Condensation between the panes. The inert gas fill has escaped through a failed edge seal, and the glass is no longer insulating. This is the most common first symptom in San Francisco’s damp, cool climate, and it only gets worse with the thermal cycling between foggy mornings and sunny afternoons.
• Water staining on the ceiling below the unit. The curb flashing or the sealant bead has failed, and water is traveling down the roof deck before it becomes visible. By the time you see ceiling stains, the leak has usually been active for weeks.
• Visible cracks in the sealant or dried, crumbling gasket material. UV and salt air harden sealants faster here than the manufacturer’s average lifespan suggests. Once the bead loses elasticity, it cracks and lets moisture wick under the frame.
• Fogged glass that won’t clear even on warm days. A failed seal lets moisture inside, and once it’s in, the only fix is a new glass unit. No amount of sun or defogging spray will change that.
• Visible rust or corrosion on the frame or fasteners. Coastal fog carries salt, and older Mr-Glass frames with steel fasteners will eventually show rust at the corners. That’s a sign the weatherproofing system is compromised and the frame needs assessment before it gets worse.

Replacement Cost & What’s Included

In San Francisco, Mr-Glass skylight and glass roofing repairs run $470 – $2,125 installed, depending on whether we’re replacing a sealant bead, a single glass pack, or a full curb-mounted unit with new flashing. The part itself is typically one-third to one-half of the price; the rest is labor, flashing, sealant, and disposal of the old glass. Every price is written before we start, and that number does not move at the door. We use code-compliant flashing details for San Francisco’s wind and moisture exposure, and every completed job is covered by the 365-Day Done Right Promise: if it leaks inside that year, we come back and correct it at no charge. Straight number, real scope, no surprises at close-out.

DIY or Call Us?

You can safely inspect the inside of the frame, photograph the label, measure the curb opening, and check for condensation between the panes. Those four steps tell us exactly what we’re dealing with before we arrive. What you shouldn’t do is climb onto a San Francisco roof to reseal a skylight yourself. Most of these roofs are steep enough that a fall is a real risk, and a failed patch job means a bigger leak and more drywall damage by spring. We carry the right Mr-Glass-compatible glass packs and flashing on the truck, and our technicians are background-checked, uniformed, and trained for roof work on pitches that make most DIYers think twice. If you think the seal has failed, call us at (831) 610-5598 and we’ll get you a written price before you ever see a ladder.
