Inspection, Scope and Sequence
Every job begins with a walk. A hands-on roof inspection means probing seams, lifting counterflashing, checking sealant joints and looking at every drain, and where the surface hides what lies beneath it, we add drone passes and infrared moisture surveys. The result is a written report with photographs, laid out so an owner can sort the urgent findings from the ones that can wait for the next budget cycle.
The scope that follows is written from those findings. It names the detail, the cause and the repair, and it separates what has to happen now from what can be scheduled. When an owner wants a replacement, the same document explains what is driving cost: access, the condition of the insulation, the number of penetrations, the amount of edge metal and the hours the building allows us to work.
On occupied buildings the sequence matters as much as the materials. We plan around tenants, deliveries, patient corridors and classes, close every section in each evening and protect the interior below the area we have opened. A crew that leaves a roof exposed overnight is not doing the job properly.
Systems and Sheet Metal
We install and repair TPO, PVC, EPDM, KEE, modified bitumen, built-up, standing seam and retrofit metal, spray foam, and silicone and acrylic coatings. Each has strengths and its own weak habit, which is why the choice of roof system gets as much thought as the day the work starts. A membrane that suits a quiet office roof may not suit a restaurant roof coated with grease or a roof walked daily by service technicians.
Sheet metal is the part of the job we take the most pride in. Parapet caps, counterflashing set into a reglet, scupper boxes and edge metal are formed by hand where the building calls for it, with soldered or properly lapped joints that move with the heat instead of opening to it. Where a roof carries a manufacturer's system, we follow that maker's published details, and the manufacturer systems we install and repair include the common single-ply, asphalt, prefabricated and thermoplastic lines.
Heat, Embers and the Rules That Follow
Pasadena has a Mediterranean climate: dry summers with a recorded high of 113 F in June, a short winter rain season that peaks in February, and a heat advisory that arrived as late as October 2023. Membranes expand and contract through all of it, and rooftop equipment runs hard. Because the San Gabriel Mountains sit close, Pasadena also receives noticeably more rain than downtown Los Angeles, and drains that were adequate in the dry months get tested quickly.
Fire has become part of the planning. The Eaton Fire in January 2025 forced JPL to close and evacuate, burned 14,021 acres near Altadena and Pasadena, and showed how wind and embers reach roof edges, vents and rooftop units. The city maps Fire Hazard Severity Zones in the Arroyo Seco and in upper Hastings Ranch, and in the highest zones a reroof calls for a Class A assembly, ember-resistant vents and debris protection.
The 2025 California codes apply to permit applications filed from January 1, 2026, and the energy code sets reflectance and emittance values for low-slope roofs that are new or heavily altered. We work out which of these rules a scope triggers before a price is given, so an owner is not surprised by the permit.
Records, Maintenance and Planning
A roof is cheaper to own when someone is watching it. Scheduled maintenance clears the debris from sumps and scuppers, tightens what the heat has loosened and records the date, so the next visit starts where the last one stopped. Owners who want the roof planned as well as maintained can ask for condition reports, capital planning, warranty records and due diligence surveys, plus programs that hold several buildings to a single standard.
A written roof condition report is the document owners use most. It helps a facilities office budget, helps a buyer or lender judge a building, and helps the next roofer understand what was done before. We write each one to be read by someone who has never stood on that roof.
The Buildings and Owners We Work For
Pasadena's commercial roofs include the brick-facade storefronts of Old Pasadena, the offices of South Lake Avenue, the theater and restaurants of the Playhouse District, the hospital district around Huntington Hospital, the Caltech campus, and the flex and warehouse space along East Foothill Boulevard. The Playhouse theater was completed in 1925, and at Caltech the Mediterranean-style buildings stand beside newer laboratories, so a single district can hold very different roofs.
Our commercial property types range from warehouses, distribution centers and cold storage to hospitals, schools, hotels, churches and government buildings. Roofing on a military installation follows base access, badging and escort procedures and the Unified Facilities Criteria for roofing, and we plan the work around them.
The owners are as varied as the buildings. Among the industries and owners we serve are property managers, investors, hospital systems, school districts, public agencies, retail and restaurant groups, manufacturers, logistics operators, general contractors and insurance restoration teams. Each runs a roof differently, and we adjust our paperwork and schedule to match.
Where the Crews Go
Our work runs through Pasadena's districts and the cities beside it, including Glendale, Burbank, Arcadia and Alhambra. The 210 and 134 freeways meet in Pasadena, and emergency calls from any of these cities are answered at any hour. The districts and cities we serve each have their own conditions, and Old Pasadena is a good example of a district where the details of brick and sheet metal decide everything.
Commercial Roofing Questions
Who answers the phone when a roof starts leaking late at night?
Emergency calls are taken around the clock, every day of the year. A crew is sent to stop the water and cover the opening, and the permanent repair is planned once the building is dry.
Is the company a fit for small buildings as well as large ones?
Yes, because the details are the same at any size. A small flex unit on East Foothill Boulevard still has edges, a drain and penetrations to flash, just as a large campus building does, and each gets the same attention.
What should a property manager bring to a first conversation?
Anything that shows the roof's history helps: past reports, warranty letters, the address of the leak and any photographs. When none of that exists, a walk of the roof gives us a place to begin.
Who receives the roof findings after an inspection?
The building owner receives the photographs and findings, including repair and replacement options, for use with any contractor.
