Expert roof waterproofing in Cornelius, NC. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Waterproofing a roof in Cornelius, NC requires more than paint-on products that peel and crack. Lapolla Industries applies spray foam and elastomeric membranes that create a true monolithic waterproof barrier — no seams, no joints, no weak points where North Carolina rain can find a path inside.
The buildings and homes of Cornelius, NC face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers roof waterproofing solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Cornelius customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner Cornelius property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional roof waterproofing results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Our reputation is built on results. Here is what our customers have to say.
"Had our entire warehouse roof restored with a spray-applied coating system. The crew worked around our operations without any disruption. The finished roof reflects heat beautifully and our AC runs less. Win-win."
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
"We signed up for their annual roof maintenance program for our three commercial buildings. They catch small issues before they become expensive repairs. Last inspection they found a failing pipe boot that would have caused a major leak."
