  • 1993 – Just Leaks, Inc. founded by Jay Marin and Scott Siemer with the goal of providing quality roof maintenance services to the San Jose region.

  • 2003 – Satellite operations in Oakland top $350,000.00.

  • 2006 – Rain Defense exceeds $1 million in revenues and maintains 10 full-time field employees.
  • 2008 – Rain Defense earns Contractors License Class C-33 (Painting/Decorating).
  • 2009 to 2013 – As the Recession moves into full swing, the renovation construction market severely contracts. While many competitor’s shut their doors, Rain Defense’s growth continues, albeit at a slower pace. During this time, Rain Defense becomes a certified installer of some of the most prestigious systems on the market including Gaco Western, WestCoat, United Coatings, GAF, Certainteed and Versico.

  • 2015 – Despite the ongoing Recession, Rain Defense reaches the $5 Million benchmark in annual revenue and retains nearly 40 full time employees.
  • 2016 – Rain Defense moves to new location at 50 Stardust Place in Alameda. The new facility shortens drive times, improves work flows and increases capabilities both administratively and for our production teams.
  • 2017 – Our Bosun’s Chair repair team increases training and certification levels in anticipation of strict new state standards coming soon.
  • 2018 – Rain Defense adds Duro-Last and KM Coatings to the growing list of certified systems we install.

The Present

Rain Defense currently serves over 250 active clients through out the San Francisco Bay Area, including property managers, community associations, investors, businesses and home owners.

Looking to the Future

The recession is finally behind us and demand for construction services is soaring. With that, there is a temptation to engage in wild growth but our strategy is very deliberate. Through development of competent personnel and excellence in our core services, we will engage in managed growth to ensure we remain an elite Building Envelope Repair & Replacement Contractor in the Bay Area.
