Whatever it is, we can repair it or replace it and your leaks will be gone for good. ![Roof-Deck](https://raindefense.com/hubfs/RainDefense/Roof-Deck.png) ## **Roof Decks** A small but growing part of the industry are roof decks. By adding a roof top deck to your property, you can increase your exterior square footage very economically. Ask us about the design firms we work with to engineer your rooftop deck. [Call Now: (510) 769-0102](tel:5107690102) ![1320-Lombard-1](https://raindefense.com/hubfs/RainDefense/1320-Lombard-1.jpg) ## **High Wall Repairs** With **Bosun’s Chair** One of our most important tools for wall waterproofing are our bosun’s chair crews. A bosun’s chair (or boatswain’s chair) is a descent system used to suspend a person from a rope for performing work aloft. Modern bosun’s chair rigging incorporates many safety devices and has changed a lot in the last decade. Rain Defense is fully certified to use this cost effective access tool for inspection, maintenance and repair of high walls.
