Spray Polyurethane Foam (SPF) Commercial Roofing
Monolithic, self-flashing closed-cell foam that insulates and waterproofs in a single seamless layer, finished with a protective elastomeric coating.
30+ years (with periodic coating recoats every 10-15 years)
Renewable warranty cycles through scheduled maintenance recoats
30+ Years Commercial Experience
Engineered commercial performance for Spray Polyurethane Foam.
Spray Polyurethane Foam (SPF) is an advanced seamless roofing system that combines exceptional thermal insulation with monolithic waterproofing. Formed by spraying two liquid components that expand 30 times their volume on contact, SPF conforms to every pipe, curb, and irregular substrate shape without a single seam, fastener, or joint. Topped with a durable elastomeric silicone or acrylic coating and ceramic granule granules, SPF provides the highest R-value per inch of any roofing material (R-6.5+ per inch).
Why Property Owners Choose Spray Polyurethane Foam
- 100% seamless and monolithic — eliminates 99% of common leak points
- Highest R-value per inch (R-6.5), slashing heating and cooling utility costs
- Self-flashing around complex penetrations, pipes, and irregular parapets
- Lightweight material eliminates structural dead-load concerns
- Indefinite lifespan with periodic silicone topcoat re-applications
Datum Installation Process
Sprayed as high-density 2.8 to 3.0 lb closed-cell polyurethane foam at a minimum 1.5-inch thickness, coated with two passes of high-solids silicone or acrylic elastomeric coating and embedded granules.
Coastal Wind & Weather Engineering
Monolithic adhesion to the deck withstands hurricane-force winds; tested past Category 4 wind uplift without blow-off.
Best Suited For
- Roofs with complex architectural shapes and dozens of penetrations
- Storage facilities, cold storage, and temperature-sensitive warehouses
- Commercial buildings seeking dramatic HVAC energy savings
- Retrofit recovery over existing metal or built-up roofs without tear-off
Datum Spray Polyurethane Foam Repair Capabilities
- Localized foam excision, closed-cell repair injection, and elastomeric topcoating
- Mechanical damage and bird-peck repair using high-solids silicone mastic
- Preventive inspection and recoating of aging protective coatings
- Thermal infrared moisture verification
Our estimating process for Spray Polyurethane Foam Projects: thorough by design, zero surprises.
With deep roots in engineering and structural restoration, Datum takes existing conditions seriously. In commercial roofing, change orders are often treated as business as usual — but to us, too many change orders are a black mark. Our estimating is always 100% free, but engineered to be exhaustive before work begins.
Only 6% of our roof replacements involve a change order.
That low rate is the direct result of core samples, deck verification, and moisture scans completed before we price the work.
Projects finish on time — and yes, we're proud of that .7%!
Detailed phasing, tenant coordination, and weather buffers keep condominium boards and owners on schedule.
Exhaustive existing condition analysis at no charge.
Full condition audit, core cuts, moisture maps, and written replacement vs. repair options for your board or management company.
1. Core sampling & deck verification
We take physical core cuts through the membrane to verify the exact assembly underneath — number of existing plies, insulation type and thickness, substrate condition, and deck type (concrete, metal, wood, gypsum). No guessing.
2. Thermal moisture scanning
Non-destructive electronic moisture meters and infrared thermal imaging map trapped moisture pockets across the roof deck so wet insulation is quantified before the proposal is written — not discovered during tear-off.
3. Ventilation & intake/exhaust analysis
We calculate intake, exhaust, and rooftop airflow dynamics to prevent condensation, pressure imbalance, and premature membrane failure. A low-slope roof without proper ventilation engineering traps moisture from below.
4. Structural condition & load review
Drawing on Lasher's 30+ years in structural restoration and engineering, we evaluate parapets, expansion joints, deck deflection, and drainage slopes so every structural constraint is solved in the upfront scope.
