Closed-cell and open-cell spray foam attic insulation that eliminates air infiltration and creates a continuous thermal barrier from ridge to eave. Most projects completed in a single day with immediate comfort improvement.

New spray polyurethane foam roof installation that creates a seamless, self-adhering membrane with the highest R-value per inch of any roofing system. Energy-efficient, leak-proof, and engineered to last 30 to 50 years with periodic recoating.
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.

Answers to the most frequently asked spray foam questions from Simi Valley property owners.
Spray foam insulation costs in Simi Valley 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 Simi Valley homeowners see a full return on investment through energy savings within 3 to 5 years.
Most residential attic insulation projects in Simi Valley are completed in a single day. Our crews prep the space, apply the spray foam to the desired thickness, and clean up within 6 to 8 hours. The foam cures within minutes, and you can feel the difference in your home comfort levels the same day.
A properly installed SPF roof in Simi Valley 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 Simi Valley we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Simi Valley. Unlike acrylic coatings, silicone does not re-emulsify in ponding water and maintains its flexibility and UV resistance for 15 to 20 years. We recommend silicone for any Simi Valley roof with drainage challenges or heavy weather exposure.
Yes. Every project in Simi Valley begins with a no-obligation roof inspection. Our crews assess the condition of your existing roof, identify problem areas using infrared moisture scanning when needed, and provide a detailed estimate with photos and recommendations. There is never a charge for the initial inspection.

"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."
"Attic insulation upgrade from blown-in to spray foam. The crew masked everything off properly and the overspray was minimal. The temperature in our attic dropped dramatically and so did our energy bills. Worth the investment."
"Lapolla Industries has been maintaining our spray foam roof for three years now. Every visit they document the condition, clean debris from drains, and address any minor issues on the spot. Peace of mind is worth every dollar."
