Solar panels on flat commercial roofs deliver sustainable energy, but they also introduce new fire risks. International investigations (IEA PVPS, BRE, NFPA, Australian regulators) show that technical failures combined with combustible roofing materials are the main drivers of rooftop PV fires. In this artikle we discuss the 10 leading causes of fire in commercial PV systems.
Solar panels on flat roofs come in many types: glass–glass, glass–foil, plastic and more. Each reacts differently to fire - but all depend on the roof beneath them. AllShield makes roofs inherently non-combustible, ensuring solar energy is both safe and insurable.
Solar energy is growing fast, but rooftop fires remain a real risk. Many ask: “How much heat can your roof coating resist?” The real question should be: “How can we stop the roof from catching fire at all?” AllShield provides two non-combustible solutions: BarrierSheet and AllShield Blue. They ensure that even when something fails in a solar installation, the fire cannot spread across the roof.
Q2 2025 saw a surge in rooftop solar (PV) fires across warehouses, factories and farms worldwide. This AllShield tracker lists each incident with date, location, likely cause and impact, plus verified sources and expert insight—so insurers and owners can benchmark risk and improve safety.
Flat roofs with solar panels offer major benefits in renewable energy, but they also increase the risk of roof fires. For building owners and insurers, it is crucial that flat roofs are not only watertight but also fire-safe and insurable.
From January–March 2025 we tracked significant rooftop PV fire incidents worldwide on commercial and agricultural buildings. Each entry lists date, what burned, where, suspected cause when known, and notable consequences like roof damage, smoke, water-damage, or PV debris.
AllShield Blue is officially FM 4482 Approved. This mineral coating creates an extra fire-resistant layer on existing roofs and makes them recognized as Class 1 Roofs – fire-safe and insurable.
Rooftop solar is booming—and so is the need to manage its fire risk. This Q4 2024 roundup highlights major rooftop PV fires on warehouses, logistics hubs and farms worldwide, with dates, locations, likely causes and consequences. All entries include primary sources.
What do solar insurers say about roof fire safety? We asked Solarif – the experts in PV insurance. Their advice: make your roof non-combustible. AllShield Blue ticks that box, keeping your solar-covered roof truly fire safe.
BouwTotaal presents AllShield Blue as a powerful solution for safeguarding flat roofs against fire. This non-combustible, mineral-based coating is easily sprayed onto existing bitumen roofs, reflects sunlight to boost PV performance, and extends the roof's lifespan, all with a single solution.
The Dutch roofing industry will gather again at Daken & Zaken, the annual trade fair where roofers, suppliers, and solar specialists connect to shape the future of roofing. AllShield will be there at stand 57, ready to share the latest in fire-safe roofing innovation.
We’re proud to announce that our water-curable, non-combustible roof coating AllShield Blue has been officially granted a European patent. Yet another recognition of our innovative work – novel, inventive, and fit for industrial use. Congratulations to the whole team!
