TPO Commercial Roofing Contractor in South Jersey & Philadelphia
Thermoplastic polyolefin single-ply membranes — energy efficient, heat-welded seams, and eligible for our industry-leading 35-year warranty on new systems.
25 to 35+ years
35-year warranty on new TPO installations; written warranty on every repair
30+ Years Commercial Experience
Engineered commercial performance for TPO.
TPO (Thermoplastic Polyolefin) is the fastest-growing commercial low-slope roofing membrane in the country. Combining the long-term weathering of EPDM rubber with the heat-welded seam strength of PVC, white TPO membranes reflect up to 87% of solar heat, dramatically reducing HVAC load and preventing thermal shock. Datum Roofing specializes in engineered TPO assemblies with custom mechanical fastening or induction welding engineered specifically for high coastal wind uplift.
Why Property Owners Choose TPO
- Industry-leading 35-year warranty on new Datum installations
- Heat-welded seams 3-4x stronger than taped or glued rubber seams
- High solar reflectance (CRRC-rated) lowers summertime cooling expenses
- Superior resistance to mold, puncture, tears, and chemical buildup
- Fully compliant with NJ and Philadelphia commercial energy codes
Datum Installation Process
Installed via mechanically attached, adhered, or rhino-bond induction-welded methods over polyisocyanurate (polyiso) rigid board insulation and cover boards, finished with robotic hot-air seam welding.
Coastal Wind & Weather Engineering
Engineered fastener spacing along perimeter and corner zones designed to resist severe Nor'easter winds and coastal salt-fog atmospheric corrosion.

Our estimating process for TPO 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.
