Trusted spray foam roofing & insulation services for Princeton, IL property owners. Licensed, insured, and backed by manufacturer warranties.
Professional roofing, coating, and insulation services for Princeton property owners and facility managers.
From minor surface patches to full-section refoaming and recoating, our repair crews restore SPF roof performance using materials compatible with your existing system. Every repair is blended seamlessly and warranted.
Metal roofs leak at fasteners, seams, and panel overlaps. Our coating systems bridge and seal every one of these failure points while adding a reflective finish that reduces surface temperatures and cooling costs significantly.
Professional flat roof repair for all membrane types — TPO, EPDM, modified bitumen, built-up, and PVC. We find the actual source of the leak using infrared scanning and fix it permanently, not with another temporary patch.
Our commercial restoration process preserves your existing roof structure, adds insulation value, and applies a warranted waterproof coating system — saving 50 to 70 percent versus tear-off and replacement on buildings of any size.
Protect your roofing investment with a maintenance program designed for your specific roof type. Our crews document every visit with photos and condition ratings so you always know the exact state of your roof.
Attic insulation with spray foam delivers the highest R-value per inch and eliminates the air infiltration that accounts for up to 40 percent of your home energy waste. Our crews install cleanly and efficiently — in and out in one day.
Hail, wind, and debris damage demand immediate attention and thorough documentation. Our crews respond quickly, document all damage with photos and measurements that satisfy insurance adjusters, and restore your roof completely.
Complete SPF roof systems for commercial and residential buildings. Our factory-trained crews apply closed-cell foam directly to your roof deck, creating a monolithic waterproof membrane that eliminates seams, joints, and the leak points they create.
Extend the life of your existing roof by 15 to 20 years with a silicone coating that seals every seam, reflects solar heat, and handles ponding water without softening or deteriorating. Professional application with manufacturer warranty.
Precision leak detection and permanent repair for active roof leaks. We use infrared moisture scanning and visual inspection to trace the leak to its source, then apply a lasting fix — not a band-aid — so it never comes back.
Roof restoration saves 50 to 70 percent compared to full replacement while delivering equivalent performance. Our SPF and coating systems seal every seam, add insulation value, and provide a reflective finish that cuts cooling costs.
Seamless waterproofing membranes applied over existing roof surfaces to eliminate leaks and ponding water permanently. Our spray-applied systems conform to every detail and create a monolithic barrier with no seams to fail.
Pre-purchase, post-storm, or routine maintenance — our inspection reports give you the data you need to make informed decisions about your roof. Infrared moisture scans reveal trapped water invisible from the surface.
Full roof replacement with spray polyurethane foam delivers superior insulation, waterproofing, and wind uplift resistance compared to conventional membrane systems. We strip the old roof, inspect the deck, and install a new SPF system built for decades.
Transform your crawl space from a moisture liability into a conditioned, energy-efficient part of your building envelope. Spray foam eliminates condensation, prevents mold conditions, and dramatically improves floor comfort above.

Answers to the most frequently asked spray foam questions from Princeton property owners.
A properly installed SPF roof in Princeton can last 30 to 50 years with periodic recoating every 10 to 15 years. The closed-cell foam itself does not degrade — only the protective topcoat needs maintenance. Many spray foam roofs installed in the 1970s are still performing today.
Closed-cell foam is denser, provides a higher R-value per inch (R-6.5 vs R-3.7), and acts as a vapor and moisture barrier. Open-cell foam is lighter, more flexible, and more affordable. For roofing applications in Princeton we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Spray foam insulation costs in Princeton typically range from $1.50 to $3.50 per square foot for open-cell and $3.00 to $7.00 per square foot for closed-cell. The exact price depends on the area being insulated, foam thickness, and accessibility. Most Princeton homeowners see a full return on investment through energy savings within 3 to 5 years.
If your commercial roof in Princeton is structurally sound but showing surface deterioration — cracked coatings, minor leaks, UV damage — restoration with SPF and a new coating system is likely the better investment. If there is widespread substrate damage, saturated insulation, or structural concerns, full replacement may be necessary. Our inspection will determine which option is right.

Honest feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"After a major hailstorm damaged our commercial roof, they walked the entire surface with us documenting every impact point. Their insurance report was so thorough the adjuster approved the full claim on the first visit. Seamless process from start to finish."
