Total project management, from preconstruction through closeout.

Zenith Construction has worked as a general contractor for more than 15 years. Every project starts with a clear scope of work, then runs on complete planning, scheduling, cost control, and closely monitored construction. Whatever the project type or budget, every detail gets the attention it deserves.

Our own crews carry most of the work, from demolition and excavation to concrete, framing, carpentry, and roofing, which keeps the schedule in our hands. Specialty trades come from a bench of qualified subcontractors held to the same dates.

Construction

We guide owners through design development so the budget and schedule hold once construction starts, and we keep a high level of service from groundbreaking to closeout.

New construction
Ground-up buildings and design-build delivery.
Tenant improvements and remodels
Tenant improvements and additions; office, retail, and restaurant remodels; apartment and condominium renovations.

S-02 · Roofing

  • Membrane and drain
  • Cover board
  • Insulation, 2 layers
  • Metal deck
  • Bar joists
  • Parapet and coping

Roofing

A roof is all that separates a building from the elements. Left alone, a small problem can turn a low-cost repair into a much larger expense. We install, maintain, and repair commercial roofing systems.

Low-slope systems
Built-up roofing (BUR), modified bitumen, elastomeric, and membrane roofing.
Steep-slope and metal
Sheet metal roofing, roof tile, and shingles.
Maintenance and repair
Repairs, flashing and sheet metal, and maintenance programs for HOAs and property managers.
