ViewLux Roofing: The San Antonio Owner’s Guide
We stock and install ViewLux-compatible roofing components across San Antonio, with most replacement jobs landing between $400 and $1,800 for roof repair work and $8,000 to $20,000 for a full ViewLux roof replacement. The typical homeowner calls us after spotting a leak near a skylight, noticing granule loss in a gutter, or finding a section of flashing that has pulled away from the chimney or vent pipe. ViewLux skylight and roofing systems age differently in Texas than they do in milder climates, and the first failure point is usually a seal, a gasket, or a flashing detail rather than the glass or the shingle itself.
Which ViewLux Models This Applies To
ViewLux manufactures skylights, sun tunnels, and roof window assemblies, and most of what we see in San Antonio homes falls into three lines: fixed skylights, vented skylights with manual or electric operation, and tubular daylighting devices. The compatibility gotcha that catches a lot of owners is the flashing kit. ViewLux flashing is profiled to the roof pitch and the roofing material, so a flashing kit rated for a 3:12 asphalt shingle roof won’t seat properly on a tile roof at 5:12, even though the glass unit is identical. Before ordering, we measure the interior frame width and length in three places, then confirm the glass tint code stamped on the inner frame edge. That tint code matters more than the model year: a clear glass unit and a Low-E tempered unit look nearly alike from inside the house, but they behave very differently in a South Texas summer. We install OEM ViewLux glass and flashing kits where they’re available, and we offer quality aftermarket gaskets and fasteners for older units where ViewLux has discontinued the original part. An independent service provider, Elmstead Remodeling San Antonio is not affiliated with ViewLux, and that independence is what lets us be honest about when an aftermarket part is actually the better buy.

Signs Your ViewLux Roofing Is Failing
- Water staining at the drywall corners below the skylight. This usually means the flashing seal has separated from the roof deck, not that the glass has cracked. The water travels down the rafter before it shows up on the ceiling, so the stain may be a foot or two away from the actual opening.
- Condensation trapped between the glass panes. When the inner seal fails, humid air gets between the panes and fogs the unit from the inside. There is no cleaning that fixes this; the sealed glass unit needs replacement.
- Acorn debris or granule piles in the gutter directly below the skylight. This often points to failing flashing or worn underlayment around the curb, not a problem with the skylight itself, but it will leak through the same opening.
- A vented skylight that cranks harder than it used to, or won’t stay open. The manual gear assembly and the electric lift motor are the two most common mechanical failures we see after eight to ten years of Texas heat cycling.
- Daylight visible around the frame edge from inside the attic. If you can see light, water can find the same path. This is a flashing and seal failure, and it’s worth a call before the next heavy storm.

AfterReplacement Cost & What’s Included
In San Antonio, a ViewLux skylight glass unit replacement typically runs $400 to $1,800 depending on glass type, frame size, and whether the flashing can be reused. A full roof replacement on a San Antonio home with ViewLux skylights runs $8,000 to $20,000, with the skylight reseal or replacement priced as a line item inside that total. What drives the range most is roof access: a single-story ranch with a walkable 4:12 pitch is quicker and safer to service than a two-story home with a steep cut-up roof. Every quote we write includes the part, the labor, the fastener and sealant materials, and the job site protection (shoe covers and drop cloths inside your home, a photo of the clean-up before the crew leaves). The written price you sign is the price you pay, no line items added after the work begins, and the installation is covered under our 365-Day Done Right Promise.
DIY or Call Us?
There are two things you can safely check yourself before you call. First, look for visible cracks in the curb flashing from the ground with binoculars; second, note whether the interior frame feels damp to the touch after a rain. What shouldn’t be a DIY project is anything involving roof access, sealant removal, or glass unit extraction. A skylight replacement done wrong leaks slowly for months before anyone notices, and by then the roof deck sheathing is damaged. Working at height on a San Antonio roof in summer adds heat exhaustion and slippery tile to the list of reasons this is a professional job. If you’ve spotted any of the signs above, call (432) 233-0976 and we’ll come take a look, write down exactly what we find, and price it before any tool leaves the truck. Write it down, price it once, do it right.
FAQs

Most ViewLux sealed glass units in the San Antonio climate hold up for 12 to 20 years before the inner seal begins to fail, with flashing often needing attention at the 15-year mark due to UV exposure and thermal cycling. Call (432) 233-0976 and we’ll inspect the unit and give you an honest remaining-lifespan read.
A flashing repair is possible when the metal is sound and only the sealant has failed, but once the flashing is bent, cracked, or corroded, replacement is the only fix that holds. We’ll show you the condition of the flashing before we quote either option.
A single skylight glass unit replacement usually takes one visit of two to four hours, including the roof work, the interior protection, and the clean-up photo. A full flashing replacement or multiple-unit job may take a full day; the written quote includes the timeline.
We stock the most common ViewLux gaskets, fasteners, and flashing profiles for San Antonio homes, along with the roof sealants rated for Texas heat, and we order the specific glass unit or motor to match your frame measurements and tint code. We also maintain stock of parts for KraftMaid, Cambria, and Silestone products for other parts of your home.
