Short answer: In many Florida projects, roof and solar work can be procured under a single contract, and doing so can simplify coordination, scheduling, warranties, and accountability. However, a single contract is only advisable when the contractor is properly qualified to perform—or lawfully subcontract—both scopes and the contract clearly separates roofing and solar responsibilities.
When a building needs both a roof replacement and a rooftop solar installation, owners often face a choice: hire one company for the complete project or contract separately with a roofing contractor and a solar contractor. The best approach depends on the project’s size, complexity, licensing requirements, financing, and who will be responsible for the finished roof-and-solar system.
Advantages of a Single Roof and Solar Contract
A single contract creates one primary point of responsibility. Instead of coordinating two independent contractors, the owner has one party responsible for the overall schedule and project coordination.
This can be particularly valuable when solar panels must be installed after a new roof is completed. The roofing and solar scopes need to be sequenced correctly, and penetrations, flashing, attachment points, structural requirements, and waterproofing details need to be coordinated.
Florida building requirements also make coordination important. Rooftop photovoltaic systems must account for structural loads, installation requirements, fire considerations, and roof penetrations. Florida code materials specifically address photovoltaic systems installed on or above roof coverings and requirements for roof penetrations and structural support.
A single contract can also reduce disputes over leaks. If a roof begins leaking after solar installation, the owner should not have to determine whether the roofer or solar installer caused the problem. A well-written contract can establish one party’s responsibility for investigating and correcting problems.
When Separate Contracts May Be Better
Separate procurement can make sense when the roofing and solar scopes are highly specialized or when the owner wants to obtain competitive bids from independent specialists.
Solar electrical work has its own licensing requirements in Florida. The Florida Department of Business and Professional Regulation states that a license is required to install photovoltaic systems and that certified or registered electrical contractors may perform solar-electric work within their licensed scope. Florida also maintains separate contractor licensing categories for roofing and solar contractors.
For a complex commercial project, separate contracts can therefore provide greater control over solar engineering, electrical work, equipment procurement, and specialized warranties.
If Using One Contract, Define the Scope Carefully
A single contract should not simply say “roof and solar installation.” It should clearly identify:
- Roof replacement or restoration scope
- Solar panels, inverters, racking, and electrical equipment
- Engineering and structural requirements
- Removal and reinstallation of existing solar equipment
- Roof penetrations and flashing details
- Permitting responsibilities
- Utility interconnection responsibilities
- Warranty responsibilities
- Leak and waterproofing obligations
- Change-order procedures
- Responsibility for damage caused by either trade
- Final inspections and closeout documentation
The contract should also identify which licensed contractor is performing each portion of the work and whether subcontractors will be used.
The Most Important Issue: Roof Warranty
Owners should pay particular attention to the roof warranty. Installing solar equipment on a new roof can affect manufacturer requirements, maintenance obligations, and future repair procedures.
Before approving the project, confirm that the roofing system, solar attachment method, and installation details are compatible with the roof manufacturer’s requirements. The contract should specify who is responsible for maintaining the roof warranty if solar equipment has to be removed or repaired later.
Best Procurement Strategy
For many commercial and multifamily projects, the strongest approach is a single point of contractual responsibility with clearly divided roofing and solar scopes. This gives the owner one party to coordinate the project while preserving clear technical and licensing responsibilities for each trade.
For smaller or highly specialized projects, separate contracts may be more appropriate.
Bottom line: Roof and solar work do not automatically need to be procured under separate contracts. A single contract can be advantageous when it provides clear scope, qualified contractors, coordinated scheduling, defined warranties, and one accountable party. Before signing, owners should verify licensing, insurance, permitting responsibilities, roof warranty requirements, and exactly who is responsible for every part of the roof-and-solar interface.
