About Syntech Roofing & Waterproofing

Family-Owned Building Envelope Contractors in Southern California

Syntech Roofing & Waterproofing is a family-owned and operated building-envelope contractor serving commercial properties across Southern California.

Our approach is simple:

Fix the problem,
not the whole thing.

We help property managers, building owners, asset managers, facilities teams, and building engineers repair and protect roofs, waterproofing systems, coatings, sealants, concrete, and other exterior building-envelope components.

When a roof, deck, wall, window, joint, or parking garage starts leaking, we look for the source of the failure, explain the repair options, and provide a clear scope before recommending a larger replacement.

Why Property Teams Call Syntech

Commercial building-envelope problems are rarely one-surface issues.

A leak may come from a failed joint, coating breakdown, roof detail, window system, deck, wall, or concrete crack.

Syntech brings multiple repair disciplines together so property teams can get clearer answers, fewer callbacks, and more practical repair options.

We work with:

  • Commercial property managers
  • Building owners
  • Asset managers
  • Facilities directors
  • Building engineers
  • Parking garage managers
  • General contractors
  • Architects, engineers, and consultants
