Trusted spray foam roofing & insulation services for Johnston, IA property owners. Licensed, insured, and backed by manufacturer warranties.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in Johnston.
Cold floors, musty smells, and high energy bills often trace back to an uninsulated or poorly insulated crawl space. Our closed-cell spray foam seals the entire crawl space envelope — walls, rim joists, and sill plates — creating a conditioned space.
Waterproof your flat or low-slope roof with a spray-applied membrane system that eliminates the seam failures, flashing leaks, and ponding damage that plague conventional roofing. One seamless application. Permanent results.
Stop metal roof leaks without replacement. Our elastomeric coating system treats rust, seals every fastener and seam, and creates a continuous waterproof membrane over your entire metal roof — backed by a manufacturer warranty.
Stop chasing flat roof leaks with temporary fixes. Our diagnostic approach pinpoints the exact failure point, and our repair methods address the root cause — whether it is failed flashing, membrane damage, or ponding water that needs re-sloping.
Transform your building with a spray foam roof that insulates, waterproofs, and strengthens in a single application. No tear-off required over most existing substrates. Backed by manufacturer warranties and our own workmanship guarantee.
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.
When your roof is structurally sound but the surface is deteriorating, restoration is the smart investment. We clean, repair, and recoat your entire roof with a warranted system that performs like new at a fraction of replacement cost.
Active roof leak? We locate the source using advanced detection methods, then repair it permanently at the root cause. No guesswork, no temporary patches — just lasting results backed by our workmanship warranty.
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.
Upgrade your attic insulation from fiberglass or cellulose to spray foam and feel the difference the same day. SPF does not settle, sag, or leave gaps — it expands to fill every cavity and seals air leaks that other materials miss.
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.
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.
Emergency storm damage response with tarping, property protection, detailed damage documentation for insurance, and complete roof restoration to pre-storm condition. We work directly with insurance adjusters.
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.
Our replacement process is thorough: remove existing roofing to the deck, inspect and repair substrate, apply closed-cell SPF to specified thickness, and finish with a UV-protective coating. The result is a monolithic roof system with no seams to fail.

Common questions about spray foam roofing and insulation in Johnston, IA.
Spray foam insulation costs in Johnston 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 Johnston homeowners see a full return on investment through energy savings within 3 to 5 years.
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 Johnston homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Yes. Spray foam roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In Johnston, this translates to significant cooling and heating savings because the seamless membrane eliminates air infiltration that accounts for up to 40 percent of energy loss in conventional roofs.
Call us immediately for emergency tarping to prevent further water damage. Our Johnston storm damage crews respond quickly to secure your property, document all damage with photos and measurements for your insurance claim, and provide a complete restoration plan. We work directly with insurance adjusters to ensure your claim is handled smoothly.
Yes. Every Johnston crew is fully licensed, bonded, and insured for spray foam roofing and insulation work. We carry general liability and workers compensation coverage on every project. You can request proof of insurance before any work begins.
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 Johnston we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
