Sika Roofing & Waterproofing
Industry-leading PVC, liquid-applied, and modified bitumen roofing and waterproofing systems engineered for long-term performance and building envelope protection.
Why We Rep Them
The case for Sika
Sika offers Sarnafil and Sikaplan PVC roofing, Sikalastic liquid-applied systems, and SikaShield modified bitumen membranes for commercial projects. The breadth of the line lets us stay with one manufacturer across single-ply roofing, seamless liquid-applied systems, and modified bitumen membranes — which keeps details, submittals, and technical support consistent from design through installation. System selection, testing, approvals, and warranty options vary by product and assembly, so we review each project individually with Sika's technical team.

Systems We Specify
PVC Single-Ply
Built to outlast the building.
One family of membranes, matched to how you're installing.

G410 is fiberglass-reinforced for adhered systems; S327 is polyester-reinforced for mechanically attached systems, carrying FM, UL, Miami-Dade, and NSF/ANSI 347 Platinum approvals. Both are heat-welded and guaranteed at labeled thickness, not the thinner "nominal" spec most manufacturers ship. Sikaplan delivers the same PVC performance at a TPO price when budget leads the decision.

Liquid-Applied
For every roof a sheet membrane can't cover.
Sikalastic cures seamless — on plaza decks, cooling towers, and skylights sheet goods can't touch.

Sikalastic cures into one seamless, monolithic membrane — sprayed, rolled, or troweled onto concrete, metal, plywood, or an existing roof with zero welded joints. It's the system for plaza decks under pavers, cooling towers, chemical containment, and skylight restoration — jobs no sheet membrane can do. Lo-VOC RoofPro systems run under 50 g/L and are SCAQMD-compliant.

Modified Bitumen
The redundant system.
SikaShield installs five ways, recovers over almost any existing roof, and waterproofs on contact.

SikaShield installs by torch, self-adhered, mechanically attached, hot, or cold application — on low-slope or steep-slope roofs, new construction or directly over most existing asphalt roofs with no tear-off. The HB79 hybrid membrane is BBA-certified to a 35+ year service life. It waterproofs immediately and holds up to wind, rain, hail, and foot traffic.
