Our Company
Powered by First Tier Exterior
San Francisco Roofing & Waterproofing is the San Francisco brand of First Tier Exterior, a Diamond Certified exterior contractor. That relationship is not a marketing line — it is where our crews, systems, and standards come from.
One Standard of Workmanship
The same crews, specifications, and inspection practices apply whether a project is sold under the First Tier Exterior name or ours. Nothing about the work changes because of the brand on the truck.
Accountable to Customers
Diamond Certified status is awarded on the strength of ongoing, independent customer-satisfaction research. It reflects completed work and rated performance rather than a self-declared claim.
Roofing and Waterproofing Together
Water does not stop at the edge of a roof. First Tier Exterior works on the building envelope as a whole — roof systems, flashing, decks, balconies, and exterior coatings.
What Diamond Certified Means
Diamond Certified is an independent credential awarded on the basis of ongoing customer satisfaction research. It is a documented record of how customers rate completed work, not a badge a contractor can purchase or award itself.
For a roofing or waterproofing project, that matters most after the job is finished — when the question is whether the work still performs a rainy season later.
