Spray Foam Services in Decatur

Professional roofing, coating, and insulation services for Decatur property owners and facility managers.

Commercial Roof Restoration

Large-scale commercial roof restoration using SPF and coating systems that extend roof life by 20 or more years without the cost and disruption of full replacement. Phased scheduling available to keep your business operational.

Attic Insulation

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.

Spray Foam Roofing Repair

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 Roof Coating

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.

Crawl Space Insulation

Spray foam insulation for crawl space walls, rim joists, and band boards that eliminates moisture, cold floors, and musty odors. Closed-cell foam acts as both insulation and vapor barrier in a single application.

Spray Foam Roofing

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.

Storm Damage Roof Repair

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.

Roof Leak Repair

Roof leaks get worse with every rain. Our crews respond fast, identify the exact source using infrared and moisture mapping, and apply permanent repairs using spray foam and coating systems designed for long-term performance.

Roof Maintenance

Preventive roof maintenance programs with scheduled inspections, drain cleaning, minor repairs, and detailed photo-documented condition reports. Catch small problems before they become expensive emergencies.

Flat Roof Repair

Flat roofs fail at seams, flashings, and penetrations. Our crews specialize in diagnosing and repairing these critical failure points using spray foam, liquid-applied membranes, and targeted coating systems that outlast conventional patch repairs.

Roof Waterproofing

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.

Roof Restoration

Complete roof restoration with spray foam and protective coatings that add 20 or more years of life to your existing roof — without the cost, waste, and disruption of a full tear-off and replacement.

Roof Replacement

When restoration is not enough, our crews perform complete roof tear-off and replacement with modern spray foam roofing systems. Full deck inspection, substrate repair, SPF application, and protective coating — all warranted.

Roof Inspection

Comprehensive roof inspections using infrared moisture scanning, core sampling, and visual assessment. Detailed photo-documented reports with condition ratings, remaining life estimates, and prioritized repair recommendations.

Silicone Roof Coating

High-performance silicone roof coatings that resist ponding water, UV degradation, and extreme temperatures. Unlike acrylics, silicone does not re-emulsify in standing water — making it ideal for flat roofs with drainage challenges.

Frequently Asked Questions

Have questions about spray foam in Decatur? We have answers.

What is the difference between open-cell and closed-cell spray foam?

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 Decatur we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.

Can spray foam fix a leaking crawl space in Decatur?

Yes. Spray foam applied to crawl space walls and rim joists creates an airtight moisture barrier that eliminates condensation, musty odors, and cold floors. For Decatur homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.

How much does spray foam insulation cost in Decatur?

Spray foam insulation costs in Decatur 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 Decatur homeowners see a full return on investment through energy savings within 3 to 5 years.

How do I know if my commercial roof needs restoration or replacement?

If your commercial roof in Decatur 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.

How long does a spray foam roof last in Decatur?

A properly installed SPF roof in Decatur 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.

How long does attic insulation installation take in Decatur?

Most residential attic insulation projects in Decatur 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.

What Our Customers Say

Honest feedback from property owners who trusted Lapolla Industries with their spray foam projects.

★★★★☆

"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."

— Charles Iverson
★★★★☆

"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."

— Kenneth Ostrowski
★★★★★

"When our TPO roof failed after only eight years we switched to spray foam for the replacement. The seamless application eliminates all the seam failures that plagued the old system. Three years in and it performs flawlessly."

— Carol Andersen
