Going solar is a smart move for many commercial property owners. It can reduce energy bills, support sustainability goals, and even increase the value of your building. But before you move ahead with installation, there’s one big question to answer:
Is your roof ready for it?
At The Duerson Corporation, we work with many businesses that are preparing to install solar panels. We specialize in commercial roofing systems like Duro-Last, and we know how important it is to make sure your roof can support your solar investment for the long haul.
Here’s what you should consider before moving forward with solar.
- Your Roof Should Have a Comparable Lifespan
Solar panels are built to last 20–30 years. If your current roof is nearing the end of its life, it’s wise to replace or restore it first. Otherwise, you could be looking at an expensive panel removal and reinstallation when it comes time for a roof replacement.
Tip: If your roof has fewer than 10 years left, consider upgrading it before installing solar panels.
- Not All Roofing Systems Are Created Equal
Some roofing materials are easier to work with when it comes to mounting solar panels. For example, the Duro-Last systems we install are a great match—they’re highly durable, energy-efficient, and flat or low-sloped, which makes panel placement simpler for your solar contractor.
Other materials, like clay tiles or aged asphalt, may present more challenges during installation and require additional prep work.
- Can Your Roof Support the Weight?
While solar panels aren’t extremely heavy, they do add extra weight—usually a few pounds per square foot. Not all roofs are structurally designed to carry that added load.
Before installing panels, it’s a good idea to have a roofing professional and structural engineer evaluate whether any reinforcements are needed.
- You’ll Still Need Access to the Roof
Once your panels are installed, your roof still needs to be accessible for inspections, maintenance, or servicing rooftop equipment. Make sure your solar installer designs the layout with proper walkways and clearance areas.
Involving your roofer early in the planning process can help avoid issues with panel placement that could make future roof work more complicated—or more expensive.
- Don’t Overlook Waterproofing
Any time a contractor mounts something to your roof—especially solar racking systems—penetrations must be properly sealed to prevent leaks. Poor sealing can lead to water infiltration, insulation damage, and mold growth.
While we don’t install solar ourselves, we work with building owners and their chosen solar companies to ensure the roof is protected during and after installation—especially when working with Duro-Last systems, which are designed with long-term performance in mind.
- Talk to Your Roofer Before You Install
Your roofer should be part of the conversation early—not after the panels are on the truck. We’ve seen too many situations where solar panels were installed on aging or damaged roofs, leading to bigger problems later.
At The Duerson Corporation, we’re happy to inspect your roof, provide honest feedback, and work with your solar provider to ensure your investment is secure from the start.
