Commercial roof assessments, national accounts & asset preservation.
One standard. One dedicated relationship. Every location. Whether you manage a multi-facility industrial portfolio, a national corporate footprint, or a condominium association planning a reserve study, Datum delivers engineered condition evaluations, core sample analysis, and asset preservation programs that maximize roof life.
Our estimating process for Commercial 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.
Roof ROI & Reserve Study Calculator
Built for condominium boards, HOA treasurers, and property managers. Model your roof's remaining useful life, project replacement costs, compare a silicone restoration against a full tear-off, and calculate the annual reserve contribution needed to avoid a special assessment. Numbers are estimates for planning — every Datum proposal includes a no-cost, engineered core-cut analysis that confirms these figures for your building.
Your Roof
Reserve & Association
Calculated from the system's expected service life (30 yrs), the roof's current age, and observed condition. A Datum core-cut assessment confirms the real number for your assembly.
Estimated full tear-off & replacement at today's pricing ($10/sq ft).
Inflation-adjusted to the projected replacement year at 4%/yr.
Silicone restoration ROI
Instead of a full tear-off now, a high-solids silicone restoration extends the roof's life by 15 years — deferring the capital replacement and its special assessment.
Why this matters to your board: Restoration is often classified as maintenance (not capital), so it can be expensed in the current year under favorable tax treatment — and it avoids a large special assessment that strains owners. A Datum assessment confirms whether your substrate is sound enough to restore.
Healthy roof — fund reserves and schedule bi-annual audits.
Your roof has an estimated 11 years of life. Setting aside $203/unit/month keeps reserves fully funded and avoids future special assessments.
This calculator provides planning estimates based on industry averages and the inputs you choose. Actual costs, remaining life, and restoration eligibility depend on a physical core-cut inspection, moisture scan, and deck verification — all included at no cost in every Datum proposal.
Engineered evaluations for buildings, boards & national portfolios.
Most organizations with more than a handful of properties manage a patchwork of regional vendors, inconsistent inspection records, and no single view of their roofing assets. Datum's assessment programs deliver unified reporting and actionable data.

Don't replace what can be preserved.
Modelled after industry-leading commercial roof asset management programs, Datum’s asset preservation approach treats your roof as an appreciating capital asset, not an inevitable expense.
We perform rigorous condition audits to separate serviceable roofs from truly failing ones. By catching minor seam defects, clearing drain clogs, and applying protective fluid-applied silicone membranes when the substrate is still sound, we extend service life by 10 to 20 years at up to 50% less cost than an occupied-building tear-off.
Condominium Reserve Studies
We partner directly with HOA boards, property management firms, and reserve engineers to establish accurate roof replacement reserves and RUL forecasts.
Lifecycle Extension (10-20 Years)
Following CentiMark-style roof asset preservation principles, proactive maintenance and fluid-applied silicone restorations can double the functional life of an existing low-slope roof, avoiding premature tear-offs.
Capital Expenditure Deferral
By identifying moisture early through thermal scans and restoring sound membranes, boards and CFOs defer multi-million dollar capital replacements and expense restorations under favorable maintenance tax rules.
Scheduled Preventative Audits
Bi-annual spring and fall roof audits inspect curbs, drains, expansion joints, and seams. Small repairs made early prevent hidden deck rot, saturated polyiso, and emergency interior disruptions.
Asset Condition Tracking
Every roof section is indexed, scored, and cataloged. You know exactly which roofs are healthy, which need routine maintenance, and which must be planned for capital replacement 3-5 years out.
Why multi-facility owners choose Datum National Accounts.
Modeled after national commercial contractors like Baker Roofing, our program provides centralized coordination and uniform standards across every location you operate.
One person owns your entire account. They know your portfolio, your priorities, and your reporting requirements. One call coordinates any roof issue.
The same safety protocols, OSHA standards, and engineering-informed workmanship follow your account across NJ, PA, DC, VA, NY, and IL.
Receive standardized condition reports, photo documentation, and billing format that integrates directly with your facility management software.
Active leaks across any facility receive priority dispatch from our regional service hubs, preventing tenant disruptions and inventory loss.
