Streamline Waterproofing Applications from a Single Team of Skilled Workers
Waterproofing protects a building from the ground up. Done right, it keeps water out of the structure and the spaces people use. Done wrong, it leads to some of the most expensive repairs a building owner can face. Sylvester Roofing's waterproofing team covers the whole building envelope, from below-grade walls and intra-slab work to large sports venues, roof deck balconies and traffic coatings in parking garages, all from a single organization.
We install both positive-side and blind-side waterproofing. Our team holds certifications with Sika, Tremco, American Hydrotech and Henry, so every system is installed to the manufacturer's standards.

Why One Team for Roofing and Waterproofing Matters
Most leaks start where two systems meet: where a roof meets a parapet, a deck meets a wall, or a plaza sits over occupied space. Because Sylvester Roofing installs roofing systems, waterproofing and architectural sheet metal, one team is responsible for those transitions. There are no gaps between trades and no question about who owns the detail.
Waterproofing Projects by Sylvester Roofing
At Fletcher Jones Audi Costa Mesa, we paired a Carlisle TPO roof with an American Hydrotech hot fluid applied waterproofing system for rooftop car parking. At North Torrey Pines Living & Learning at UC San Diego, the same Hydrotech system sits under elevated pedestal pavers. At Callan Ridge, our waterproofing supports an expansive green roof.
