Property owners in DeKalb, IL deal with the same roofing and insulation challenges as everywhere else — leaking flat roofs, sky-high energy bills, deteriorating roof coatings, and contractors who apply band-aid fixes that fail within a season. Lapolla Industries takes a different approach: we find the root cause, apply the right spray foam solution, and back it with a real warranty.
With over 40,624 residents depending on reliable buildings, DeKalb needs contractors who show up, do the work right, and stand behind it. Lapolla Industries has built our reputation on exactly that — thousands of spray foam roofing and insulation projects completed nationwide, with the same attention to quality whether the building is a 500-square-foot garage or a 100,000-square-foot warehouse.

SPF roofing delivers the highest R-value per inch of any commercial insulation. Our customers typically see 20 to 40 percent reductions in heating and cooling costs after installation.
Unlike conventional roofing with seams, joints, and fasteners, spray foam creates a monolithic membrane with zero penetration points — eliminating the most common sources of roof leaks.
Lapolla Industries has been at the forefront of spray polyurethane foam technology since 2003 — with deep roots in SPF manufacturing and application that few competitors can match.
Have questions about spray foam in DeKalb? We have answers.

There is never a charge for the initial inspection.
Spray foam is one of the best solutions for flat and low-slope roofs in DeKalb. The seamless application eliminates the seams and joints where conventional flat roof systems fail. SPF also self-levels to eliminate ponding water — one of the biggest causes of flat roof leaks and premature failure.
If your commercial roof in DeKalb 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.
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 DeKalb we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Spray foam insulation costs in DeKalb 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 DeKalb homeowners see a full return on investment through energy savings within 3 to 5 years.
