Commercial Services

From One Leak to a Full Re-Roof.

Self-performed commercial roofing — our own crews on your roof, one accountable contractor from assessment to closeout.

Flat & Low-Slope Systems

Torch-applied modified bitumen and waterproof deck systems for flat and low-slope commercial roofs — installed by crews who do this work every week, not brokered out.

Commercial Re-Roof & Recover

Full tear-off and replacement, or a recover over the existing system where the substrate allows — we assess honestly and price both paths when both are viable.

Repairs & Leak Response

Leak diagnosis and repair with photo documentation of cause and fix — the paper trail you need for owners, tenants, and insurance files.

Preventive Maintenance Programs

Scheduled inspections, drain and penetration checks, and minor repairs on a predictable cadence — catching $500 problems before they become $50,000 ones.

Condition Reports & Budgeting

Roof condition assessments with remaining-life estimates — the numbers you need for capital planning, reserves, acquisitions, and lease negotiations.

Restoration & Insurance Scopes

We work alongside restoration contractors and property managers on insurance-scope roofing — clean scopes, clean documentation, no surprises at closeout.

Why Building Owners & PMs Choose NRG

Paperwork as Clean as the Roof.

Documentation First

Photo-documented inspections, written scopes, and condition reports built for owners, boards, lenders and insurance files.

Measured Bids, Not Allowances

Every number comes from a real takeoff. You see the scope, the system, and the price before you commit — and the price holds.

Tenant-Aware Scheduling

Occupied buildings stay occupied. We sequence work, protect entries, and keep tenants informed so business doesn't stop for the roof.

One Contractor, More Trades

NRG also self-performs carpentry/framing and electrical — rotted blocking, equipment curbs, and penetrations get handled without a second mobilization.

Commercial FAQ

What Owners & Property Managers Ask.

Can you maintain a roof you didn't install?+

Yes. Most maintenance-program roofs weren't ours originally. We start with a documented baseline inspection, fix what's urgent, and put the rest on a scheduled plan with a per-visit report.

Repair, restore, or replace — how do you decide?+

By condition, not by what's most profitable to sell. If the membrane has serviceable life, we'll tell you — a repair-and-maintain plan often defers a replacement for years. When replacement is genuinely the right call, we show you the evidence in photos.

Do you handle multi-building portfolios?+

Yes. We inspect and report per building, so property managers get one contractor, one point of contact, and consistent documentation across the portfolio. For condo and apartment communities, see our HOA & multifamily roofing services.

Can you provide reports for insurance or an acquisition?+

Yes — roof condition reports with photos and remaining-life estimates are one of our core services, and we're used to working with adjusters, restoration GCs, and buyers in escrow.

Are you licensed and insured for commercial work?+

Yes — CSLB C-39 #1156853, bonded and insured. Certificates of insurance are available on request, and you can verify the license at cslb.ca.gov.
