Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Lapolla Industries coated our standing seam metal roof with a reflective system that stopped the leaks at the panel overlaps. The building stays significantly cooler in summer and the coating has held up perfectly through two winters."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"Called about a ceiling stain that kept growing. They got on the roof, found the leak source at a HVAC curb penetration, and had it sealed within hours. Professional, fast, and the price was exactly what they quoted."
