Comprehensive spray foam roofing and insulation services tailored for Dundalk properties.
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.
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.
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.
Full roof replacement with spray polyurethane foam delivers superior insulation, waterproofing, and wind uplift resistance compared to conventional membrane systems. We strip the old roof, inspect the deck, and install a new SPF system built for decades.
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.
Professional flat roof repair for all membrane types — TPO, EPDM, modified bitumen, built-up, and PVC. We find the actual source of the leak using infrared scanning and fix it permanently, not with another temporary patch.
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.
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.
Know the true condition of your roof before problems escalate. Our inspection process covers every component — membrane, flashings, penetrations, drains, and substrate — and delivers a clear, actionable report you can trust.
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.
Commercial roofs deteriorate from the surface down. If your structure and deck are sound, restoration with spray foam and silicone coating is the economically superior choice. We handle buildings from 5,000 to 500,000 square feet.
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.
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.
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.

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 comes backed by manufacturer material warranties plus our own workmanship guarantee. We handle all warranty registration so you are always covered.
Answers to the most frequently asked spray foam questions from Dundalk property owners.
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 Dundalk homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Dundalk. 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 Dundalk roof with drainage challenges or heavy weather exposure.
Spray foam insulation costs in Dundalk 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 Dundalk homeowners see a full return on investment through energy savings within 3 to 5 years.
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 Dundalk we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
In most cases, yes. One of the biggest advantages of SPF roofing is that it can be applied directly over existing roof membranes — TPO, EPDM, built-up, and even metal — without a costly tear-off. Our Dundalk crews evaluate the existing substrate to ensure it is structurally sound before application.
Yes. Every Dundalk 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.

"The silicone coating they applied to our metal roof eliminated all the rust spots and sealed every seam and fastener. The reflective finish dropped our cooling costs noticeably. Our building looks ten years newer."
"We had a persistent leak that three different contractors could not find. Their team used moisture scanning equipment and pinpointed it to a failed pipe boot in minutes. Fixed it the same day. Incredible diagnostic work."
"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."
