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
Leaks, flashing problems, or localized damage? A targeted repair may address the problem without replacing the entire roof.
Restore
When the existing roof is a suitable candidate, a restoration or coating system may help extend its service life.
Replace
When deterioration is extensive, a complete roof replacement may provide the better long-term solution for the property.

Commercial Roofing Contractor
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.

Commercial Roofing FAQ
Answers to common questions about commercial roof inspections, repairs, restoration, replacement, and flat and low-slope roofing systems.
The right solution depends on the condition of the existing roof, the extent of any damage, drainage, flashing, penetrations, seams, and the roofing system already in place. Localized problems may be addressed with commercial roof repair, while some existing roofs may be candidates for restoration. When deterioration is more extensive, commercial roof replacement may be the more appropriate option. A roof inspection is the best place to start.
We provide roofing services for commercial flat and low-slope properties, including TPO roofing, torch down roofing, and eligible roofs that may be suitable for silicone roof coating applications. The appropriate roofing system or service depends on the property, existing roof conditions, drainage, and project requirements.
TPO is a single-ply roofing membrane commonly used on commercial flat and low-slope roofs. The membrane is installed across the roof surface and the seams are heat-welded to create a continuous roofing system. Whether TPO is appropriate for a property depends on the existing roof, roof design, drainage, and project requirements.
In some situations, yes. If the existing commercial roof is still in suitable condition, restoration may be an option instead of a complete roof replacement. Silicone roof coating is one restoration option for eligible roofing systems. The existing roof must first be evaluated to determine whether restoration is appropriate.
Silicone roof coating may be an option for certain existing commercial roofing systems that are suitable for restoration. It creates a seamless coating over the prepared roof surface and can be used as part of a commercial roof restoration project. An inspection is necessary to determine whether the existing roof is an appropriate candidate for coating.
Yes. Commercial roof leaks can come from a variety of areas, including flashing, penetrations, seams, drainage areas, or localized damage. Our inspection process is designed to evaluate the visible roof conditions and identify problem areas before recommending the appropriate commercial roof repair.
A commercial roof inspection begins with evaluating the existing roofing system and visible roof conditions. We look at areas such as drainage, flashing, penetrations, seams, and visible problem areas. Based on the condition of the roof, we can then explain whether targeted repair, restoration, or replacement may be appropriate.
