Available in structural standing-seam profiles with concealed clips that allow thermal expansion and contraction, metal roofs endure coastal salt spray, intense storms, and heavy snow loads with minimal maintenance. Datum Roofing engineers, fabricates, repairs, and installs Galvalume, aluminum, and copper metal roofing systems designed to protect properties for half a century.

Our estimating process for Metal Roofing 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.
