Local conditions
What San Bernardino's Climate Does to a Commercial Roof
San Bernardino roofs deal with conditions that coastal buildings don't. Knowing these conditions helps you plan maintenance and catch problems before they reach the inside of the building.
Extreme summer heat and UV.
Temperatures on the valley floor regularly go above 105°F. Over time, heat and sun wear down membranes, sealants, and flashings. Seams and edges are often the first places to fail.
Santa Ana winds.
Strong winds funnel through the Cajon Pass and across the valley. Wind uplift puts stress on roof edges, seams, flashing, and the curbs around rooftop equipment.
Rain after long dry months.
Small cracks and open seams can go unnoticed all summer. They often show up as leaks during the first storms of the season, when a repair is hardest to schedule.
Large low-slope roofs.
San Bernardino sits in one of the largest logistics hubs in the country. That includes AllianceCalifornia, a 2,000-acre trade and logistics hub on the former Norton Air Force Base. Warehouse and industrial roofs cover huge areas and have many drains, penetrations, and HVAC units. A single failed detail can put a large area of floor space at risk.
For most San Bernardino properties, the best time for an inspection is late summer or early fall, before the rainy season starts.
Services

Roof Inspections
We check the roof surface, seams, flashing, drains, and penetrations so you know the roof's condition before any work is proposed.
Infrared Leak Detection
Infrared scans help find areas where moisture may be trapped under the roof surface. This guides where we look more closely and keeps repairs focused.
Roof Moisture Scans
A moisture scan shows how much of the roof system is wet. This is often the deciding factor between repair, coating, or another approach.
Targeted Repairs & Patching
When the problem is limited to one area, a targeted repair can fix it without a larger project.
Leak Prevention & Annual Maintenance Programs
Scheduled inspections and routine maintenance help your team catch wear early and plan roof costs ahead of time, not after a leak.
Full Roof Coatings & Restoration
For eligible roofs, a liquid-applied coating can add protection and extend the roof's service life. We first confirm the roof is a good candidate.
Replacement Guidance
When the roof's condition points to replacement, we explain our findings and walk you through the proposed scope.
Your options
Repair, Maintain, Restore, or Replace?
A leak alone doesn't mean you need a new roof. The roof system, how much of it is wet, and how long you plan to hold the building all affect the right choice.
| Option | When it may fit | What we look at |
|---|---|---|
| Targeted repair | A specific area, seam, or penetration is failing | The source of the leak and how the repair ties into the existing system |
| Planned maintenance | The roof is sound but aging | Inspection schedule, routine upkeep, annual maintenance programs |
| Coating or restoration | The roof is mostly dry and structurally sound | Existing system, moisture scan results, exposure, protection needed |
| Replacement | Moisture or damage is widespread | Site visit findings and the proposed scope |
Roof coatings
Roof Coating Options for Inland Heat
Common commercial roof coatings include silicone, acrylic, and urethane. Each one performs differently. Before recommending a coating, we look at adhesion, flexibility, UV resistance, the existing roof, and how it will be applied.
| Coating type | General strengths | Things to consider |
|---|---|---|
| Silicone | Strong UV resistance; handles ponding water well | The roof needs proper prep; recoating later requires compatible products |
| Acrylic | Reflective; a good fit for sun-exposed roofs | Works best on roofs with good drainage |
| Urethane | Tough; holds up to foot traffic and impact | Often used where durability is the priority |
California's Title 24 energy code includes cool roof requirements. These can apply when a low-slope nonresidential roof is replaced, re-covered, or recoated. We take these requirements into account when we discuss coating options.

Project experience
Project Results
Camino Nuevo School District: Roof Restoration
Ten More Years Under the Dome
The school needed a budget-conscious way to keep its domed roof in service for about 10 more years before a planned sale. The work also had to be finished in two weeks. Syntech installed a Tremco liquid-applied roof coating system that met the performance needs without over-engineering the job. The curved roof and tight schedule called for careful sequencing and extra safety measures.
Northrop Grumman: Façade & Window Sealant Repair
Test First, Spend Less
The first assumption was that the building needed a large-scale restoration. Syntech ran systematic leak tests instead and traced the water to the window perimeters. The project became a targeted sealant repair, not a much larger restoration. The same test-first approach guides how we assess your roof.
CSU San Bernardino: Full Building Envelope Reseal
Local, Occupied, and on a Tight Schedule
The campus stayed occupied around the clock, the schedule was compressed, and the building had no rooftop setup for swing-stage access. Syntech built custom tieback and lifeline systems and stayed in constant contact with university engineering staff. This was not a roofing project, but it shows our experience working on occupied buildings in San Bernardino.

FAQ
Commercial Roofing FAQs
How do I know if my commercial roof needs repair or replacement?
A leak alone doesn't mean you need a new roof. The roof system, how much of it holds moisture, and your plans for the building all matter. We assess the roof first, often with infrared or moisture scans, then discuss repair, maintenance, coating, or replacement.
Is the site visit free?
Yes. Book a free site visit and we'll look at the roof and discuss next steps.
What decides whether my roof can be coated?
It depends on the roof system, its condition, how much moisture is trapped, and its exposure. In general, a roof that is mostly dry and structurally sound is a better candidate.
How long does a commercial roof project take?
It depends on the scope. A targeted repair may take a day or two. A larger coating project takes longer. For example, the Camino Nuevo roof restoration was finished within a two-week schedule. Your proposal will include timing.
Can you work while my building is in use?
Yes. We've worked on a 24/7 occupied campus, a busy arena, and a secure corporate site. We plan the work around your tenants and operations.
Do Title 24 cool roof rules apply to my project?
They can. California's energy code includes cool roof requirements that may apply when a low-slope nonresidential roof is replaced, re-covered, or recoated. We take this into account when we recommend a system.
Do you offer a warranty?
A 20-year no-dollar-limit warranty on labor and materials is available on eligible systems. Coverage depends on the system and the scope.
What if the leak isn't coming from the roof?
Sometimes it isn't. Water can enter through parapets, wall joints, windows, or transitions. Syntech also provides sealant, coating, and waterproofing services, so we can trace the source and fix it.
