Not Just Commercial Roofing

The waterproofing of a building system extends beyond simply the roofing system. Best Roofing's commercial waterproofing expertise extends to below-grade building structures including substrates, patios, decks, parking structures, foundation walls and sub-structures.


The rehabilitation of existing parking decks, especially those with occupied space below, such as roof-top parking, requires specialized knowledge. Typically the existing system has to be removed or neutralized, and a new one applied. The selection of the new system to withstand traffic wear, oils, and rubber residue requires the guidance of a contractor that has experience in the performance of various options under the conditions the particular project presents.

The selection of the correct system for these decks depends upon exposure, traffic patterns, and the aesthetics demanded by the client. Finish choices include the selection of color and various textures including anti-slip surfacing. Non-visible waterproofing systems for these decks include between-slab membranes and under-tile waterproofing.
