Find the Right Solution

What Does Your Commercial Roof Need?

Not every commercial roof needs to be replaced. The right solution depends on the roof’s condition, existing system, and the extent of the damage.

Repair

Commercial Roof Repair

Leaks, flashing problems, or localized damage? A targeted repair may address the problem without replacing the entire roof.

Explore Roof Repair

Restore

Roof Restoration

When the existing roof is a suitable candidate, a restoration or coating system may help extend its service life.

Explore Restoration

Replace

Commercial Roof Replacement

When deterioration is extensive, a complete roof replacement may provide the better long-term solution for the property.

Commercial Roofing Built Around Your Property

Commercial roofs require a different approach than residential roofing. Flat and low-slope roof systems must be evaluated based on their existing condition, drainage, penetrations, flashing, seams, and the roofing system already in place.

First Roofing Contractor provides commercial roofing services across Southern California for property owners, property managers, and commercial facilities. Our work includes commercial roof inspections, roof repair, roof restoration, roof replacement, and roofing systems for flat and low-slope properties.

Whether the property has a TPO roofing system, torch down roofing, or an existing roof that may be suitable for a silicone roof coating, the first step is understanding the condition of the roof and determining the appropriate scope of work.

The goal is not to recommend the same solution for every property. Depending on the roof’s condition, the appropriate path may involve targeted repairs, restoration of an eligible existing roof, or complete roof replacement.

    Review of visible roof conditions, problem areas, drainage, flashing, penetrations, and the existing roofing system.

  • Clear Recommendations

    A clear explanation of the roof condition and the recommended scope of work.

We hired First Roofing Contractor to replace the old roof on our commercial building with a new TPO system. From the first inspection to the final walkthrough, everything was handled professionally. They explained the different options, answered all of our questions and kept us updated throughout the project. The crew was organized and worked efficiently without causing major disruption to our business. The new roof looks great and the whole experience was much smoother than I expected. I would definitely recommend First Roofing Contractor for commercial roofing work.

Really good experience with First Roofing Contractor. We were originally expecting to replace our entire commercial roof, but after inspecting it they recommended a silicone coating system instead. I appreciated that they gave us an option that made more sense for the condition of our roof instead of automatically pushing us toward a full replacement. The work was completed on schedule and everything looks great. Very professional company.

yelp review

We had a leak in our flat roof that two other roofers had already tried to fix. Every time it rained, the leak came back. First Roofing Contractor came out, found where the water was actually getting in and repaired it. We’ve had rain since then and no more leaking. Simple, professional and they actually fixed the problem. Would definitely call them again.

I own a commercial building with multiple tenants, so my biggest concern with replacing the roof was how much the construction would interfere with their businesses. First Roofing Contractor did an excellent job coordinating everything. They communicated with me throughout the project, kept the work areas organized and made sure we knew what was happening each day. My tenants were able to continue operating while the roofing work was being done, which was extremely important to me. The project was completed as promised and the new roof looks excellent. I’m very happy with the decision to hire them.

As a property manager, I deal with a lot of contractors and communication is usually the biggest issue. That was not the case with First Roofing Contractor. We called them for a commercial roof issue at one of our properties and they were responsive from the beginning. They provided photos, explained what needed to be repaired and kept me updated without me having to constantly follow up. The job was completed on time and the property was left clean. I’ve already saved their number for future roofing projects.

thumbtack review

Our warehouse roof was getting old and we started noticing water coming in during heavier rain. I contacted First Roofing Contractor after getting a recommendation from another business owner. They inspected the roof and were very straightforward about what needed to be done. The price was reasonable compared to the other estimates we received, but what really sold me was how comfortable I felt dealing with their team. They showed up when they said they would, finished the project within the timeframe they gave us and cleaned everything up afterward. It’s been a great experience from start to finish. If you own a commercial property and need a reliable roofing company, I highly recommend First Roofing Contractor.
