Cover Construction in Los Altos, CA | Viceroy Construction
We handle Cover skylight and roof window service across Los Altos as your Los Altos General Contractor, from leak tracing and flashing replacement to full unit swaps on ranch homes and second-story additions. We’re an independent contractor, not a Cover-authorized dealer, which means we answer to you and your roof, not a manufacturer’s warranty department. What separates our Los Altos work from any other market is simple: we know how a 1950s ranch roofline with low slope and shallow clearances interacts with a Cover curb-mounted unit after thirty years of thermal cycling. Call (877) 358-6557 when you want someone who’s actually stood on a Los Altos roof and diagnosed the problem.
Before we get into the weeds, know this: if you’re dealing with a leaking Cover skylight or a fogged fixed unit, the fix is almost always cheaper than you fear, and almost never requires a full roof tear-off. More on that below.
Why Los Altos Residents Choose Us for Cover Service
Our familiarity with Cover’s product line comes from years of hands-on work, not from a training video. We’ve pulled apart Cover Skylight Series units, re-flashed Cover Roof Windows, and replaced fogged Cover Flat Roof Window glass on Peninsula ranch homes from Los Altos to Saratoga. Neil Drummond grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where framing and structural coursework taught him something that sticks: a skylight is only as good as the roof system around it. We’ve also provided Cover service in Stanford and neighboring communities. That’s the lens we bring to every Cover job in Los Altos.
We stock common Cover flashing kits, gaskets, and sealants locally so a 94022 or 94024 service call doesn’t turn into a two-week parts wait. When you call, we can usually tell you over the phone whether it’s a flashing issue, a glass-seal failure, or an operator problem, and what that means for your budget.

Common Cover Construction Problems We Solve in Los Altos
- Condensation and fogging between panes in fixed skylights. Los Altos bathrooms and kitchens run humid in winter. When warm interior air hits cold glass on a 38-degree morning, a failed thermal seal shows up as persistent fog that won’t wipe away. The fix is glass replacement or full-unit swap, not a tube of silicone.
- Leaking at the curb flashing on Cover roof windows. Low-slope ranch roofs in Los Altos let water pause during November-March storms. Add years of thermal cycling and the flashing seam opens up. We see this constantly on homes built in the 1950s and 1960s where the original Cover unit was installed with outdated flashing details.
- Cracked or brittle polycarbonate domes on older Cover models. Long, dry Peninsula summers hammer UV onto aging domes. A 20-year-old Cover dome that looks fine from the ground can be spider-cracked up close, and it’ll fail the moment a winter storm drops two inches of rain on it.
- Sticking hinges or failed operators on vented Cover skylights. Heritage street trees drop leaves, seeds, and fine debris into tracks. On Los Altos streets with mature oaks, we regularly open a vented skylight and find the track packed with gunk that’s been grinding the operator for years.
- Water stains showing up on ceilings below a second-story addition tie-in. Older Los Altos additions often routed a Cover skylight into a low-slope tie-in that was never properly cricketed. The stain shows up years later, and the fix is flashing plus drainage correction, not drywall patching.
Cover Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos has a design-review process that neighbors actually attend. That changes where a Cover skylight can go on a second-story addition. Because lots are wide but shallow and many streets were fully built out by the 1960s, adding a second floor often triggers a neighborhood compatibility review. A new Cover roof window positioned to face a neighbor’s one-story ranch bedroom window will draw privacy objections and stall your permit. In Sunnyvale or with a Cover service in Mountain View, that same unit goes in with a standard submittal. In Los Altos, we sometimes reposition a skylight by three or four feet to keep the sight line from becoming somebody’s complaint at a planning meeting. That’s not boilerplate stuff you get from a national roofing company. It’s the difference between a permit that moves and one that sits.
Cover Models & Products We Service in Los Altos
We service the Cover Skylight Series, Cover Roof Window, and Cover Flat Roof Window lines, including discontinued models from the 1980s and 1990s that show up on original Los Altos ranch homes. Our parts approach: OEM Cover glass and flashing kits whenever the model is still supported, because fit and finish matter on a curb-mounted unit. For discontinued models, we use aftermarket seals and operators that meet or exceed the original spec. We don’t cut corners with generic flashing tape and call it a repair.
We also carry the materials to match Cover units to existing tile roofs, which matters on the Spanish-tile ranch homes scattered through Los Altos. A mismatched flashing on a tile roof is a leak waiting for the first winter storm.

AfterCover Service Pricing in Los Altos
| Service | Typical Range |
|---|---|
| Roof Repair (Cover skylight flashing) | $400 – $1,800 |
| Roof Replacement & Installation | $8,000 – $20,000 |
| Tile Roof Repair | $600 – $2,500 |
Flashing repairs on a single Cover unit usually fall in the $400 to $1,800 range depending on access, roof pitch, and whether we’re re-flashing one curb or redoing a tie-in. A full roof replacement is a different animal, and the range reflects tile versus composition, tear-off versus overlay, and roof complexity. A free estimate means we come out, get on the roof, and show you exactly what’s wrong and what it costs before you commit. Call (877) 358-6557 and we’ll schedule it.

FAQs – Cover Construction in Los Altos
Yes, in nearly every case. A leak at the curb flashing or glass seal is a localized repair, not a roof replacement. Even when the underlayment around the unit has rotted, we replace that section, not the whole roof. Call (877) 358-6557 for an exact diagnosis, and we’ll tell you straight if a repair makes sense or if the unit is beyond saving.
Yes, and we coordinate the placement with Los Altos’s design-review requirements from the start. That means accounting for privacy sight lines to adjacent one-story ranches, which can affect where the unit goes and how it’s flashed. We’ve pulled permits on Los Altos additions where a skylight position change made the difference between a smooth review and a resubmittal.
Most Cover units last 20 to 30 years in Los Altos, but the seal and flashing deteriorate faster here than in drier inland markets because winter wet seasons stress the curb and the UV summers bake the dome. A unit from the 1990s is usually near the end of its service life, even if it hasn’t failed yet. Call (877) 358-6557 if you want us to assess one before it becomes a ceiling stain.
Yes. We cut and shape flashing to match your tile profile, and we carry materials for flat, S-tile, and low-profile tile profiles common across Los Altos. A properly matched flashing keeps water out and looks like it was always there. If you’re not sure what tile profile you have, send us a photo or call (877) 358-6557.
We prioritize active leaks during the November-March wet season. If a Cover unit is leaking during a storm, we can usually get a tarp or temporary seal on it same day, then schedule the permanent repair once the roof dries. Call (877) 358-6557 and tell us it’s an active leak.
