FAQ

Common Questions

What waterproofing systems does On Top Commercial Roofing install?+

On Top Commercial Roofing installs commercial waterproofing systems for rooftop decks, below-grade foundations, plaza decks, expansion joints, and building envelopes. We use proven systems from leading manufacturers including fluid-applied membranes, sheet membranes, and hybrid waterproofing assemblies tailored to each application.

What is the difference between commercial roofing and waterproofing?+

Commercial roofing protects the top surface of a building from the elements. Waterproofing goes further — it seals the entire building envelope including vertical walls, below-grade foundations, podium decks, and any area where water intrusion is a risk. On Top Commercial Roofing handles both, giving you a fully integrated protection strategy.

Do you waterproof below-grade foundations and parking structures?+

Yes. On Top Commercial Roofing provides below-grade waterproofing for foundations, tunnels, plazas over occupied space, and parking structures. We use appropriate negative-side and positive-side waterproofing systems depending on your site conditions and structural requirements.

How long do commercial waterproofing systems last?+

High-quality commercial waterproofing systems installed by certified contractors typically last 20 to 30 years or more, depending on the system type, application conditions, and maintenance. Fluid-applied systems can often be recoated to extend service life. On Top Commercial Roofing helps you choose the system best suited for your building's long-term needs.
