30+ Years Commercial Experience
Engineered commercial performance for EPDM.
EPDM (Ethylene Propylene Diene Monomer) is the classic high-performance synthetic rubber membrane that has protected Northeast commercial and industrial buildings for over five decades. Known for extreme flexibility in freezing Mid-Atlantic winters and relentless summer sun, EPDM does not shatter, crack, or become brittle with age. Datum Roofing inspects, repairs, seam-tapes, and replaces 45-mil, 60-mil, and 90-mil reinforced EPDM roofing assemblies across NJ and PA.
Why Property Owners Choose EPDM
- Remains elastic even in extreme sub-zero winter temperatures (-40°F)
- Unmatched resistance to atmospheric ozone, UV radiation, and hail impact
- Proven 50+ year track record on Mid-Atlantic commercial buildings
- Cost-effective installation and straightforward localized repairability
- Available in ballasted, fully adhered, or mechanically fastened assemblies
Datum Installation Process
Installed as fully adhered with solvent-based bonding adhesive or low-VOC adhesives over high-density polyiso insulation, or mechanically fastened with heavy-duty seam plates.
Coastal Wind & Weather Engineering
Elastic rubber naturally absorbs wind fatigue cycles and thermal contraction during coastal ocean temperature swings.
Best Suited For
- Industrial manufacturing plants and warehouse complexes
- Schools, municipal buildings, and institutions
- Condominium buildings with ballasted or black-membrane specifications
- Properties with large, uninterrupted roof areas
Datum EPDM Repair Capabilities
- Stripping-in failed lap seams with primer and cured EPDM cover strips
- Wall flashing restoration, termination bar resealing, and counterflashing
- Gutter apron and edge metal tie-in repairs
- Drain sump and scupper bowl rebuilding
Our estimating process for EPDM 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.
