I'm trying to find a company to repair the leaks in this solar pool heating system on the roof, but one solar company I called told me it's a "mat" style - which they don't repair. I'm attaching a photo of the system. Does anyone know if this IS a mat style and if so, can leaks be repaired, and if so, by who? I think this system is less than 8 years old. The places I called are solar companies and they sound like they just want to sell a new system.
