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.

What We Do
Syntech focuses on four core building-envelope services:
Commercial Roofing
Roof repairs, roof maintenance, roof coatings, overlays, and practical repair scopes for commercial buildings, warehouses, multifamily properties, and industrial facilities.
Waterproofing
Leak investigation, below-grade waterproofing, planter and plaza waterproofing, deck and balcony waterproofing, and water-intrusion repair for commercial properties.
Coatings and Sealants
Roof and wall coatings, caulking, building-envelope joint re-seal, expansion joints, window leak repairs, deck coatings, and parking garage traffic coatings.
Concrete Restoration and Injection Repair
Epoxy and urethane crack injection, concrete crack repair, spall repair, masonry restoration, and structural concrete repair for commercial and parking garage environments.
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
