Trusted spray foam roofing & insulation services for McHenry, IL property owners. Licensed, insured, and backed by manufacturer warranties.
Professional roofing, coating, and insulation services for McHenry property owners and facility managers.
Expert repair for existing SPF roofs including blistering, coating deterioration, punctures, and storm damage. We restore your foam roof to like-new condition with matching materials and factory-specified application techniques.
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.
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.
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.
Ponding water, chronic leaks, and moisture infiltration destroy roofs and building interiors. Our waterproofing systems use closed-cell spray foam and silicone coatings to create an impermeable barrier that handles standing water indefinitely.
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.
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.
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.
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.
Silicone coatings provide the longest service life of any roof coating product. Our crews apply them over metal, TPO, EPDM, built-up, and spray foam surfaces — sealing the entire roof in a seamless, reflective, waterproof membrane.
When severe weather damages your roof, our storm response crews deploy fast — securing your property, documenting every impact point for your insurance claim, and restoring your roof with quality materials and expert workmanship.
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.
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.
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.
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.
McHenry, IL is home to a growing mix of commercial, industrial, and residential properties — and Lapolla Industries serves all of them with professional spray foam roofing and insulation. Our SPF systems are particularly effective for the flat-roofed commercial buildings common in McHenry, where conventional membrane roofs develop seam failures and ponding issues within years of installation.
For McHenry facility managers and building owners, spray foam offers something no other roofing system can: a single application that provides waterproofing, insulation, and structural reinforcement simultaneously. No separate vapor barrier. No separate insulation board. No seams to fail. Just one seamless, self-adhering membrane that protects your McHenry investment for decades.
Here is what sets Lapolla Industries apart from other contractors in McHenry.
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.
Every project comes backed by manufacturer material warranties plus our own workmanship guarantee. We handle all warranty registration so you are always covered.
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.
Every project starts with a no-obligation inspection using infrared moisture scanning and visual assessment. We identify every issue and provide an honest, transparent estimate.
Have questions about spray foam in McHenry? We have answers.
A properly installed SPF roof in McHenry 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.
Yes. Spray foam roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In McHenry, 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.
Spray foam insulation costs in McHenry 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 McHenry homeowners see a full return on investment through energy savings within 3 to 5 years.
If your commercial roof in McHenry 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.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in McHenry. 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 McHenry roof with drainage challenges or heavy weather exposure.
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 McHenry homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Honest feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"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."
"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."
"Ponding water on our flat roof was causing constant problems. They re-sloped the low spots with tapered foam and applied a silicone coating. No more standing water after rain. Excellent work."
