Repairs, maintenance and replacements for offices, warehouses, retail buildings and other commercial properties – flat, low-slope and everything in between.
Commercial roofs behave differently than residential ones, and they usually can't afford to shut a business down for a project. We plan around your operations, focus on the problem areas and keep communication clear the whole way through.
Commercial roofing covers repairs, maintenance and full replacements on offices, warehouses, retail buildings and other commercial properties. Flat and low-slope systems are common, and they behave differently than residential roofs.
Leaks, drainage issues, worn membranes and failing flashing are the problems we see most. Work has to be planned so it doesn't disrupt daily operations more than necessary.
Most issues start with water sitting somewhere it shouldn't. Drains clog, seams separate, and flashing pulls loose around units and walls. Once water starts pooling, materials break down fast.
We also see a lot of older patch work on commercial roofs – temporary fixes that were never meant to last forever. Southern California sun and heat wear those down, and leaks usually come back in the same areas.
Not every commercial roof needs replacing. Many issues can be handled with targeted repair if the system still has life left.
When leaks keep popping up across the roof or moisture is widespread, replacement often makes more sense long-term. Commercial roofing starts with figuring out which situation you're actually in.
Most start with an inspection to identify problem areas and decide whether repair or replacement makes sense. From there we walk through scope, timing and access.
Some repairs are quick. Larger projects take more coordination. We work around business hours where possible and keep communication clear throughout the project.

Heat is rough on commercial roofs here. Membranes dry out faster, adhesives weaken and daily temperature changes cause constant movement. Over time that stress adds up.
Heavy rain also exposes drainage problems fast. Even a small slope issue can lead to standing water and quicker material breakdown on a large commercial roof.
Commercial roofing work typically requires a permit through the local jurisdiction, and larger replacements may involve additional review depending on the building's occupancy type and the scope of work. We handle permit submission and coordinate inspections so the paperwork doesn't hold up your project or create issues down the line for insurance or a future sale.
For properties with rooftop HVAC units, satellite equipment or solar, we also make sure any new roofing work is properly flashed and integrated around existing equipment rather than treated as an afterthought – that's a common source of failed inspections and callback leaks on commercial buildings.
We know a roof project can't just shut a warehouse or retail space down. Most commercial work gets scheduled around your hours – early mornings, weekends, or phased section by section so part of the roof is always weathertight while we work on the rest.
For multi-tenant buildings we coordinate with property management on tenant notices, noise windows and access, so the people working underneath the roof aren't surprised by a crew showing up. Clear scheduling up front is usually what keeps a commercial roofing project from becoming a headache for everyone involved.
Roofing systems
01 · Materials we install
The everyday workhorses. Three-tab and architectural asphalt shingles cover most homes we touch, and we still hand-cut wood shake repairs and set metal panels where a roof calls for it. Good value, fast turnaround, easy to service years down the road.
Best for: Most tract and custom homes across Southern California
02 · Materials we install
Heavier, thicker profiles that mimic slate or hand-split shake without the weight or the price. They carry longer manufacturer coverage, hold up better in wind, and give a plain roofline real depth from the street.
Best for: Homeowners who want tile presence with shingle simplicity
03 · Materials we install
Classic Southern California. Tile itself lasts decades, but the underlayment beneath it does not. We lift and stack, replace the paper and metal, then reset or convert depending on what makes sense for the house.
Best for: Spanish, Mediterranean and mission-style homes
04 · Materials we install
Single-ply membrane for low-slope and flat roofs. Heat-welded seams instead of adhesives, a bright reflective surface that keeps attic temperatures down, and a clean surface for solar to sit on later.
Best for: Flat residential decks and commercial buildings
05 · Materials we install
Concealed-fastener panels with raised seams, so there are no exposed screws to back out and leak. It sheds water and debris fast, handles coastal weather, and pairs well with clamp-mounted solar that never penetrates the roof.
Best for: Modern builds, additions, patio and carport roofs
06 · Materials we install
The details most crews rush. Custom-bent flashing, coping, gravel stops, cricket and chimney pans, scuppers and gutters fabricated to fit the actual roof instead of a stock length from the supply house.
Best for: Tricky transitions, parapets and chimney details
07 · Materials we install
Built-up hot mop and torch-down modified bitumen. Multiple reinforced plies fused into one waterproof mass, which is still the toughest answer for a flat roof that ponds water or takes regular foot traffic.
Best for: Flat roofs, decks and roofs with heavy service traffic
