Fascias, Canopies and Storefront Sheet Metal
Retail owners pay for curb appeal, and a lot of it is sheet metal. Fascia panels, mansard returns, canopy covers and parapet caps frame the storefront, and they are also the first place a roof leaks into a wall. A canopy that is flashed into a masonry face without a reglet will let water behind the wall for years before anything shows on the ceiling inside the unit.
Along Colorado Boulevard and in the brick-faced storefronts of Old Pasadena, fascia and cap metal is as much a part of a storefront's look as the paint. We form replacement metal to match the existing profile, solder or lap the seams so each joint can move, and set new counterflashing into sound masonry. Where the exterior has to stay presentable for customers, we finish the metal before we leave the area, so the owner gets a clean frontage and a roof that is tight at the edge.
Phasing Bay by Bay Around Customers and Deliveries
A shopping center earns its income on weekends and in the holiday season, so we plan the heaviest work for the slow part of the calendar and keep loud work off the busiest hours. We close in each section by the end of the day, set staging where it will not block loading zones or accessible parking, and stage hoisting away from storefront entries. The tenant mix matters: a restaurant wants no work near its intake at lunch, a medical suite wants the noise kept down during appointments, and a gym wants early mornings left alone.
That kind of occupied building reroofing requires a written schedule and a name on our side that tenants can call. We give the property manager a tenant notice before each phase, mark the work zone on a site plan and keep access to rooftop equipment open for each tenant's own service technicians, so a repair on one bay does not turn into a complaint from another.
Reports Owners and Tenants Can Both Read
The roof is a shared asset paid for through a lease structure, and a good written report makes that arrangement easier to run. Ours lists each bay, the condition of the membrane over it, the equipment on it and any wet insulation found by an infrared survey. A property manager can use the report to allocate repairs to the owner or to the tenant whose equipment caused the damage, and to plan a reroof before the leases come up for renewal.
Many owners hold centers inside a portfolio, and the same report format works across the several properties of a real estate investor or REIT. A big-box store at the end of the strip may have a different roof age and warranty status than the bays beside it, and we separate those in the report so nothing is lumped together. A tenant who adds a rooftop unit later should add a record, and we update the report whenever that happens.
Heat, Wind and Fire Rules at the Foothill Edge
Retail roofs in the San Gabriel Valley sit in full sun for most of the year. The June record stands at 113 F, and an advisory in October 2023 showed that hard heat does not wait for summer. A white membrane that has not been cleaned runs hotter and ages faster, and a membrane with dark dirt on it can lose much of the reflectance the 2025 California Energy Code expects of a new low-slope roof. We wash and test before deciding whether a coating can restore the surface, and our roof coating restoration process includes a check of the seams.
Centers near the foothills face a second set of rules. Pasadena's Fire Hazard Severity Zones include upper Hastings Ranch in East Pasadena, and in a Very High zone the state wildland-urban interface rules ask for a Class A covering, ember-resistant vents and gutter debris protection when a reroof covers more than half of the roof in a year. In Arcadia, Westfield Santa Anita is the main draw of the Baldwin Avenue commercial district and Foothill Boulevard serves the city's other centers, which share the San Gabriel Valley's long dry summers, so a white membrane there needs the same cleaning and testing.
Commercial Roofing Questions
Who pays when a leak in one bay is caused by a neighbor's rooftop unit?
The lease decides, but our findings make the question easier to settle. We trace the water to its source, photograph the failed curb or boot, and note which tenant's equipment sits there. The property manager can then apply the lease terms with real evidence instead of guessing, and we can repair the opening so it does not repeat.
Can part of a center be reroofed while the rest stays on the old roof?
Yes, and it is a common way to spread cost. The new section is tied to the old one with a proper termination, and the old roof keeps getting maintenance until its turn comes. We check that the two sections drain separately, so water from the new roof does not run onto a weaker area.
Will the work block parking or the storefronts during the holiday season?
We try to avoid that period altogether. Heavy phases are placed in the slow months, and when a holiday-season repair cannot wait, we limit it to the small area needed and leave the frontage clear. Staging, hoisting and dumpsters go behind the building or in a marked corner of the lot.
How do you handle restaurant tenants with grease on the roof?
Grease needs its own plan, the same one a restaurant roof gets. We clean the area around the exhaust fans, add a containment pan or a grease-rated membrane where needed, and recommend a cleaning schedule with the tenant. Left alone, grease softens and eats through many common membranes, and the damage spreads from the fan outward.
Is a recover over the old roof allowed on a retail building?
Often it is, if the old insulation is dry and the deck is sound. A moisture survey tells us where the old roof is wet, and the building code limits how many layers can sit on a deck. A recover keeps tenants out of the dust and noise of tear-off, so it fits many centers, while a wet roof must be torn off.
