Hiring separate contractors can cause delays, cost overruns, and unclear accountability. Choosing one experienced contractor for both ensures your project runs smoothly. When roofing and solar installation for your business are handled by different companies, accountability becomes unclear if something goes wrong. For example, if a roof leak occurs, the building owner typically calls their roofing contractor. But if it turns out the leak was caused by the solar installation, the roofing company may charge for the repair, and that’s when the finger-pointing begins. The result? Delays, frustration, and unexpected costs. Choosing a contractor who can manage both roofing and solar keeps the process simple and headache-free. The timeline runs smoother, inspections go faster, and both systems are designed to work together from day one. In this blog, we’ll cover everything you need to know before installing a new commercial roof and solar panels for your business, so you can save time, reduce risk, and protect your investment. ## One Project. Two Upgrades. Commercial roofs typically last 20-25 years. Solar panels usually come with 25-year warranties. ​​If you install solar panels on an aging roof that could  mean paying for the same labor twice. Removal, reinstallation, and downtime costs will add up fast.  Combining your [commercial roofing project](https://citadelrs.com/commercial/roofing/)along with your [solar investment](https://citadelrs.com/commercial/solar/) eliminates double disruption and double paperwork. Your contractor can design the roof and solar system to work together perfectly, and you can use solar savings to help offset roofing costs. ## Here’s how your project should unfold with the right contractor: - **Assessment and Planning:** Your roof gets thoroughly evaluated, and any needed repairs are built into the design. Design and Engineering: Roofing and solar design are engineered together, so structural loads, [fire codes,](https://osfm.fire.ca.gov/what-we-do/code-development-and-analysis/battery-energy-storage-systems)and electrical needs are built into one plan. - **Permitting:** A single contractor handles [permitting](https://pv-magazine-usa.com/2025/09/29/california-allows-flexible-interconnection-for-distributed-solar-storage-to-avoid-grid-upgrades/), so paperwork is consistent and the project stays on schedule.  - **Installation:** Installation of roofing and solar is on the same schedule to minimize business disruptions.  - **Wrap Up:** Once the project is complete, you have one team to answer questions and handle any follow-up issues.  ## Things to Look For (and Watch Out For) 1. **Check Their Licenses and Certifications (All of Them):** A solid commercial roofing company won't hesitate to show you license numbers and certifications. And you can double-check with the [California Contractors State License Board](https://www2.cslb.ca.gov/onlineservices/checklicenseII/checklicense.aspx).  2. **Look for Local Expertise:** Find contractors who've done projects like yours nearby and know how to manage them. They should know[local codes](https://www.dgs.ca.gov/BSC/Codes)and permitting, but also how to coordinate crews without turning your property into chaos. 3. **Understand Warranty Coverage**: Roofing and solar warranties are separate, but they need to work together. Your contractor should provide clear workmanship warranties for roofing installation and help you understand solar manufacturer warranties. ### Expensive Mistakes That Hurt Businesses - **Putting Solar on Old Roofs:** This is just an expensive cycle. You pay to install solar panels, then pay again to remove them for roof repairs, then pay a third time to put the panels back. A thorough roof assessment before solar installation will make sure you avoid this costly merry-go-round. - **Poor Coordination Between Teams:** When roofing and solar contractors work separately, scheduling conflicts and communication failures are practically guaranteed. If there’s a weather delay, it can cause delays that snowball throughout the project. - **Rushing Assessments:** Solar panels add weight and wind pressure to your roof. Contractors who rush the assessment can create problems that show up during the next big storm. - **Choosing the Lowest Bid:** The low bids you see often come with hidden costs. Cheap materials wear out faster, and rushed workmanship leads to repairs that could have been avoided. A reputable contractor is upfront about costs because they’re confident in the quality of their work. ### Save Yourself the Headache Separate contractors create unnecessary complications, and coordinating them all is exhausting.  With one contractor in charge, the project is designed, managed, and built as a whole. Find a contractor who handles both roofing and solar, then let them worry about making it all work together. **Our comparison chart makes it easy to see the difference between hiring multiple contractors versus one integrated provider.** With a single team handling both roofing and solar, you streamline communication, reduce costs, and ensure warranties and schedules align from the start. ![Comparison of separate contractors vs. one integrated contractor for roofing and solar. Integrated contractor provides streamlined scheduling, permitting, labor, communication, and warranty. Separate contractors often cause delays, duplicate work, higher costs, and warranty confusion.](https://blog.citadelrs.com/hs-fs/hubfs/Separate%20Contractors%20vs.%20One%20Integrated%20Commercial%20Roofing%20%26%20Solar%20Contractor%20Comparison.png?width=800&height=600&name=Separate%20Contractors%20vs.%20One%20Integrated%20Commercial%20Roofing%20%26%20Solar%20Contractor%20Comparison.png)   ### Why Businesses Trust Citadel We’ve been roofing [California businesses](https://citadelrs.com/commercial/roofing/) for more than 30 years and [installing solar for over 20](https://citadelrs.com/commercial/solar/).
