Roofing
VertX manages tear-offs, re-roofs, and roof repairs in composition shingle, tile, and metal for homes in West Covina and across the San Gabriel Valley. Every roof is built solar-ready and managed by VertX from tear-off to final inspection.
Most roofers never think about what happens above the shingles. VertX does, because half of our business is solar. That changes how projects get planned: load paths planned for future panels, flashing details that survive penetrations, and materials chosen for a 25-year service life, not a quick handoff.
For composition shingle roofs we install GAF and Owens Corning, the two largest shingle manufacturers in North America. Most of our re-roofs use GAF Timberline HDZ or Owens Corning Duration architectural shingles: both Class A fire rated, both built to hold through Santa Ana winds, and both backed by a manufacturer limited warranty on top of our own workmanship warranty. Both lines also come in cool-roof colors that meet California's Title 24 energy code, which matters on a west-facing roof in the San Gabriel Valley.
We install the full system from each manufacturer, not just the shingle: matching underlayment, starter strip, ridge cap, and ventilation. That is what keeps the manufacturer warranty intact and what keeps the roof sealed around solar mounts.
Owens Corning shingle systems, installed by VertX Every project starts with a free inspection with photos you keep, whether or not you hire us. If the roof has ten good years left, we'll say so. If it doesn't, and you're considering solar, you'll want to know before anyone bolts a 25-year system onto it.
Where we do this
Each city has its own page: the utility, the permit path, fire-zone status, and the kind of homes we see there.
Common questions
A repair makes sense when the roof is fundamentally sound and the damage is local: a few lifted shingles or one bad flashing. If the roof is near the end of its service life, repairs become a subscription. We inspect, photograph everything, and tell you which one you actually need.
Asphalt composition shingle from GAF and Owens Corning, concrete and clay tile, and metal. We match material recommendations to the house, the neighborhood, and whether solar is part of the plan.
Mount blocking and flashing planned into the roof from day one, so when panels go on, now or in five years, nobody is cutting into a finished roof. It costs little during a re-roof and saves real money later.
Yes. Re-roofs are permitted with your city and inspected. If solar is part of the project, we combine both into one permit package: fewer inspection visits, faster timeline.
If the roof has less life left than the panels, yes, and it is cheaper to do it now than to pay to remove and reinstall the array later. We inspect the roof first and show you the photos. If it is sound, we will say so and put solar on it as-is.
Most single-family re-roofs are done in a few days, with tile taking longer than composition shingle. Weather and the city's inspection schedule can add time. You get a schedule before we start, and we tell you if it moves.
Yes, concrete and clay tile are a big part of what we do in the San Gabriel Valley. Tile itself often outlasts the underlayment beneath it, so many tile jobs are a lift-and-relay: reuse the tile, replace the underlayment and flashing. We inspect and tell you which job you actually need.
Usually only for sudden damage like wind, a fallen branch, or a fire, not for a roof that has simply worn out. If you have storm damage, we document it with photos you can send to your adjuster. Age-related replacement is out of pocket, which is where financing comes in.
